welcome to Technologies discussion Channel today I like to continue the discussion on EMC consideration okay so for this video I'm going to explain why we need to do EMC testing firstly let's thank some of you guys actually suggest valuable suggestion how to improve this video again because of your So-Cal respond your suggestion I have decided to do a enhanced discussion on this part two series discussion okay so therefore this video I'm going to explain why we need to perform EMC testing for me I feel that if you understand the motivation okay why we need to
do this then you will be able to appreciate that so therefore this video I'm going to explain why we need to do EMC testing so that later on you will be able to appreciate why we need to do this essential task this will be the part two series discussion on EMC so guys if you ke to know more about EMC okay please take a look on the playlist under the description over there you will be able to find a series of discussion on EMC this is my email if you have any question regards on this
discussion okay please drop me an email okay or if not if you want to have a faster respond you are also welcome to ask me your question through the comment I also sit the support of those expert in this learning committee to give me some suggestion or maybe provide some input so that all of us actually can learn as a whole before I continue okay I'd like to urge you guys to help this channel by like this video just give me a few second by helping to press the like button thank you so much for
those who are new to this Channel please consider to subscribe and turn on your notification Bell once again thank you so much much for S support these are the six reason that why EMC testing is necessary EMC testing is actually a very critical part of product development so as to ensure that our newly developed electronics and electrical device they actually function properly in their intense environments so these are the six six key reason okay why we need to do this EMC testing first one will be limited electromagnetic spectrum okay we know that spectrum is a
limited resource so therefore we need to manage this spectrum efficiently okay so therefore we cannot allow any new build device okay even for those old buil device they cannot afford to be transmitt at any frequency they are not intend to so therefore we need to have this emission criteria to limit the emission from the electronics device next G will be the regulator compliance so basically every countries have some compliance for example us have FCC control Europe actually have this C control so basically based on the different region that you intend to sell your newly built
device you need to ensure that they actually compliant to respective So-Cal compliant test before you can actually start to sell in that particular region next we need to ensure that the device is able to work in a function manner for example okay when you attribute a new product you need to ensure that they do not overly contribute the emission that can be a disturbance Source from the nearby device we also need to ensure that any new device that you actually meet okay they are able to withstand certain amount of electromagnetic spectrum if not it will
not be able to function properly so therefore because of this we need to ensure that the device is actually properly function okay in term of emission and also imunity next will be on the safety okay so safety is basically you just imagine this any new device that you actually make okay it actually has a reset suddenly without you knowing so this can become a very hazardous okay so therefore we need to ensure that the device will be able to compliant so as we don't have this scenario of resetting so therefore this is a life and
matter so therefore we need to ensure the safety okay by doing EMC we actually can guarantee some form of safety next will be the quality of performance of the product okay again it will be highly related to safety but in term of this some of the product may not require very high standard of safety as compared to safety so therefore for example some a product we can actually allow them to do a reset however we cannot have frequent reset so therefore this EMC testing actually ensure the quality of performance of the product last but not
least is on product recall and F okay so I will give you an example okay of a So-Cal a product record from a global soal example okay so therefore when you actually has a product record it can be harmful give to to the company reputation so therefore with EMC testing we actually reduce the product record and if you don't compliant to the So-Cal Regulatory Compliance you may subject to have some form of f so basically these are all the six key reason why EMC testing is necessary and we will go through one by one in
deep discussion okay the first one is what I mentioned earlier on okay which is the limited electromagnetic spectrum okay so we know that we actually have a finite amount of electromagnetic spectrum for transmission okay basically any electronic device okay if let's say they require to transmit in order to function okay so therefore when every electronics device transmit there will be a lot of interference so therefore we need to manage the Spectrum efficiently okay so unfortunately even those Electronics device without any transmitter which means that they don't require to transmit in order to function they also
emit electromagnetic wave okay so this can be another potential issue without limitation to the amount of unint electromagnetic radiation from Electronics products the electromagnetic spectrum could be messy and frequency band reserve for radio transmission could become compromised again you can imagine that for example you build a Electronics device beside the intend frequency they also transmit at the unint frequency or maybe I should not say that they transmit okay they release the EM wave unintentionally this can be a interference okay for those nearby device or maybe also for those that is actually intend to reserve for
radio transmission because of this so therefore we need to ensure that the electromagnetic spectrum G need to be well managed next okay as the number of wireless Electronics product continues to grow exponent financially the already pack electromagnetic spectrum is going to become even more crowded okay we know that the amount of electronics device in our household for example they grow exponentially so everything in our households almost everything become smart we have Smart TV we have Smart fridge we have Smart washing machine Etc so because of this okay the already back electromagnetic spectrum they will be
even more crowded so again this require some management of electromagnetic spectrum protection of this essential resource become very critical so as to ensure that device continue to be able to function properly in the future so basically this is the first reason okay because of the limit electromagnetic spectrum so therefore we have this EMC criteria to ensure that any Electronics device okay they do not have any unint electromagnetic radiation even as so okay we need to ensure that they need to be compliant at certain limit level so basically this is the first reason reason number two
okay will be because of the rules of different region okay so the governments and international organization actually establish EMC regulation so as to ensure that Electronics device do not cause harmful interference or suffer from it so basically firstly is on the emission emission may cause harmful interference next okay we need to ensure that our new build device will not be suffer from So-Cal the EM environment okay so that they actually intend to work with EMC testing actually help manufacturer compliant with this regulation okay so basically this is the second reason okay because of the rules
from different region most country actually have this regulation okay in short they are actually a legal requirement okay which means that you cannot avoid is a legal requirement okay that mandate EMC testing so as to ensure the product actually meet specific standard for example SEC KY will be us CE will be from Europe okay compliance actually ensure product can be legally sold and actually operate in the market so basically this is what I have explained early on based on the region that you actually plan to soal launch your new product for example you plan to
Launch in US you need to ensure that you actually comply the EMC standard according to the FCC rule if you plan to launch in Europe then you need to ensure that the new product that you actually launch actually compliant to the C standard so basically this is very important next meeting International EMC standard actually allow manufacturer to distribute product across multiple region under the framework of Global Market assess okay because most of the time when we actually make any new product we don't intend to launch in one particular So-Cal country we plan to launch it
under multiple region so therefore okay we need to ensure that whatever device they must be able to compliant under different soal EMC rules and regulation next as the density of electronics device in home office and Industry environment actually increase ensure that device can actually coexist without interference is critical for technology progress okay so this is what I have explained earlier on also okay you just imagine this if you m a new device that actually Emit and interference for example to the Bluetooth then the Bluetooth device that they actually use they will have a lot of
interference and there will be a lot of loss message then this may not allow the different technology to co assist because of this and because of the So-Cal the legal compliant by different region therefore with this we actually can ensure that different technology can actually coexist without creating any interference to the other Technologies so this is the reason number two because of the different region compliant so therefore we need to ensure that our newly built device need to be compliant before we can actually start to sell in the different region in the world reason number
three okay we need to ensure that it actually properly function okay so Electronics device that emit electromagnetic signal that can interfere with other devices EMC testing ensure product do not disrupt the operation of nearby equipment and minimize interference so basically this part you can imagine it as a emission any new electronics product that we actually mean okay we need to ensure that they do not unint release electromagnetic signal that potentially can become a interference source with nearby device once you have this soal unint emission Okay this may cause some interference with nearby device and in
result may cause the device not able to function properly so basically this is the reason number three in term of emission okay so next on the immunity okay so basically where we actually do this EMC testing okay they actually also confirm that the device have immunity to some form of interference okay they will be able to resist external electromagnetic disturbance and they are able to continue to function reliability okay so basically this is a emission this is a immunity we need to ensure no over okay emission released by The dut we also need to ensure
that our D able to function in it in 10 function in the real world environment next okay EMC test product provide customer with assurance and also trust in technology ensuring they are actually purchasing a safe and reliable device imagine with EMC okay so basically we know that there won't be any form of radiation so therefore we are actually purchasing a very safe and reliable product and also when we actually have the immunity test on the dut okay again with this we can ensure that what the thing supposed to be able to soal function properly and
therefore again with this we actually ensure that we actually purchase a safe and reliable device next okay EMC certification is often regards as a mark of quality and Market differentiation okay helping Brands stand out okay so if you look at most of the bigger brand they actually compliant to the EMC okay some of the smaller brand on a newly startup okay therefore they still not able to soal compliant to the EMC so therefore if you able to achieve EMC certification This is highly regard as a mark of quality and also to differentiate that your product
is actually one gr higher than the rest okay so basically this is reason number three okay to ensure proper function of your duty in term of emission and also in term of immunity next in term of safety okay so past EMC test can mean the difference between life and that okay so basically this is very important okay so many application okay like in the medical military industry Aerospace and Automotive product they actually have safety critical application okay they need to be continue working in order for us to be safe okay so later on I'll give
you an example okay why this safety is very important like this line mentioned okay so we have a lot of application okay be it in the medical environment be in the military okay if anything fail to work then it become a safety issue so therefore EMC test actually ensure that all these device they are able to continue to work okay in order for us to be safe okay uncontrolled electromagnetic emission they can actually L to the malfunction in critical system such as medical device or Automotive system that become a risk to human safety nowaday a
lot of Automotive become Electronics device so therefore any form of disturbance or interference can be become a very hazardous effect so therefore we need to control the electromagnetic emission next okay by medicate electromagnetic risk EMC testing actually protect the user from potential harm due to equipment failure if any of the function of those product fa okay due to electromagnetic phenomen such as power supply search Okay earlier on I have largely discussed about So-Cal interference for example now for example we have this power supply search which means that they search up maybe 20% more and if
this can kill the device so we need to ensure that even with a reasonable power supply search our device still able to function properly or maybe because of ESD okay so basically when you actually have a ESD okay your device can be unfunctional so basically this is also very critical so this is what I have discussed most of the time which is the radi electric view that can cause the disturbance to the duty and therefore the life can certainly be at risk okay so let me give you an example okay imagine in boing aircraft over
300 mobile phone okay let's say now a day typically for boing aircraft okay we have about maybe 200 or maybe even 300 because some some of you guys actually hold two mobile phone or maybe smartw watch Etc so typically we have lots of soal emission let's say we have about 300 mobile phone on board all transmitting three watt of power okay it is the regress EMC testing that ensure all the electrical system of the Boeing aircraft can with stem those sort of electromagnetic environment okay because when we actually do this test on the soal on
the Aeros space for example okay again you can encourage everybody don't bring your mobile phone on board okay everybody will bring their mobile phone in and we need to do a very stringent test for example let's say 300 over mobile phone actually imit up three wat of power okay we need to ensure that okay all the electrical system of the Boeing aircraft they are able to withstand this sort of interference so basically this is reason number four okay so any malfunction due to EMC can become a safety issue so this is reason number four okay
before I continue guys okay I'd like to urge you guys again to help this channel by like this video if you had learned something from this video and you are new to this channel urge you to help this channel by subscribe to it and also turn on your notification Bell once again thank you so much for song support next on the reason number five the quality of performance of the product the function and performance of a product can easily be affected or degrade by certain or internal generate EMC Fon GUI earlier on I talk about
safety which means that total malfunction in this case here basically the function of performance of a product will be affected and will be degraded okay by external or internal generate EMC Phenom let's take a close look EMC testing actually ensure that the performance Assurance of the product remain consistent in real world electromagnetic environment reduce the risk of downtime caused by electromagnetic interference improve the operational reliability of the products for example okay if the internal power supply is too noisy and this can affect the sensitive analog data for sensor okay so basically this is one of
the example okay for example all the disturbance actually went through the power supply and this noise Source reach the analog data for example because this analog data also require power so therefore the noise actually reach the analog dat data uh reach the sensor okay through the analog data cable and this may come a big issue EMC phenomenon like our cellular based station emission can negatively affect Electronics products from data Corruptions because of degration of RF performance okay so EMC testing helps to ensure that the device will continue to work and function as expected in the
presence of a typical EMC environment okay so basically this is reason number five the quality of performance of the products next okay on the last reason okay we want to minimize the product recall and also potentially five by the different regulation here okay reduce recall and penalties peing to meet EMC standard can lead to costly product Rec course fight and even loss of reputation okay so nowaday I think a lot of big company okay emphasized on reputation everything can go into social media so your reputation can be destroyed just one particular case of product recall
okay mitigate legal risk non-compliant can actually result in lawsuit okay under some extreme case it can be result in a lawsuit if a product cause interference or Fs in critical scenario if your company is caught selling product on the market that is non-compliant the consequence can vary from insignificant to scary okay so basically if you have selling some product that do not oite to EMC for example in the different region you actually have different rules in term of EMC so if you are C selling product okay that your product do not compliant to the MC
standard okay so it can be very insignificant but it can be a nightmare because you are going to face lots of lawsuit which can be quite So-Cal disturbing okay in term of your company progress okay for example your company may involve in complicated lawsuit and required to pay a fine or in some case JE okay a product recall is also a possible consequence and is a very painful process okay for example this thing although it happened quite sometime which is the Samsung Galaxy Note 7 I'm not sure whether you still remember this issue here okay
the battery actually has some fult it become quite explosive and because of some issue of this uh So-Cal mobile phone export in air uh aircraft get some potential Airline actually ban any soal passenger that actually carry a Samsung Galaxy phone uh Note 7 okay if you carry this Samsung Galaxy Note 7 at that particular time you may also require to off it completely okay so basically because of this okay a product record can be a soal possible consequence and from this example you can see a a painful lesson learned by Samsung okay because of the
40 battery 40 okay they actually need to do a product recall okay so let me do a quick conclusion okay before I end this discussion EMC testing is a very important and comprehensive progress that ensure the safety reliable and compliance operation of electronics and electrical device in today increasing complex and interconnect environment okay so B see this is very important now more and more device are required to connect to each other in order to function so therefore because of this we are going to have some increased complexity because they are linked somehow and therefore we
need to have soal ensure that we need to do some form of EMC testing so as the function will be able to work normally and also we do not introduce emission that can cause a disturbance okay more than just a regulatory requirement it is actually a critical step in product development that Safeguard functionality that enhance user trust and minimize R for both manufacturer and end user by addressing both emission and Immunity EMC testing support technology con coist ensure products are fit for the intent environment that make it an indisposable part of the development and certification
of modern Electronics device okay so with this okay I like to end my discussion okay please to like And subscribe once again thank you so much for song support I hope to see you guys soon bye for now thank you
