@@HaseebElectronics In the past I opened epoxy blocks containing parts using hot air. Yes it's a bad smell but I did it outside. It's quicker than using flame. The very hard epoxy will break off in small pieces easily. I don't think that small flame will do anything for thick solid epoxy.
if that is hard material then it is near to impossible, because that is epoxy based filling. if that is some soft material then it is rubber sealant, that can be removed by slow heating and scratching carefully
Hello Ashraf Sb..salamah Its really good trick but I had created some damages on tracks while components generally stops my tool. I used temp controlled airgun to get Silocon soft. I noticed silicons have variations in formulation n thickness that need higher or lower temperatures. The best I did was I heated the PCB on non Si side with temp of 200 deg c for 2 min n later about 300 deg c on Si side while keeping the comp side over 150 deg c. I used Temp monitoring gun to have reasonable temp on both side. The outcome was I was able to peel bigger pieces of Si rather than dust or granule. One must keep in mind the fire safety as I had fire alarms in shop location due to high level of infrared radiation...lol Syed Arif Akhter Toronto Canada
This coating already breaks the same way i see you doing after the "heating with alcohol" because it is silicone base. There is no need for that. Hope you are not starting to make fake videos to get dumb people attention. Keep your videos professional, you are already doing an awesome work.
@FixDaily this coating is very hard, until we heat with hot air gun, or hair dryer or siprit lamp or heatup using gasoline drops / alcohol it never allows to enter knife or sharp screw driver or scrapper. i don't attempt to make fake or misleading. i just share whatever i know or whatever i have practical. i never copy other's ideas. anyone can oppose to my opinion / thoughts / practical / words please accept my best regards
@FixDaily i have this LG 6870EC9025C board. if you have same board please try it to remove if you are successful, please record a short clip and you can send it to my gmail id ashraf4ta4 or whatsapp 00962795608616 i will welcome and send special thanks
It might be worth taking hi resolution close-up picture of the board right through coating as it still intact and transparent. It might help in case some components get damaged or dislocated during coating removal.
Como te mencionaron es mejor la pustola de aire caliente pero he visto que la placa la dejas limpia debe de haber algo mas. Pero buen video saludos desde peru
Sí, pistola de aire caliente, secador de pelo, quema de gotas de gasolina o alcohol son las mismas técnicas para retirar este revestimiento rígido a base de silicona.
you need to replace the IGBT module. If you remove the gel, you will end up breaking the bound wires. Even if you can remove the gel, what are you going to do about the IGBT itself? Are you able to solder bound wires or replace the silicone chip? No!. You are more likely to replace that module with regular IGBT components than fixing it.
that is epoxy based coating. you need hammering to remove and it will destroy the module just for study purpose you can dismentle it, but not for repair purpose
SIr, I am always watching your videos and I really like them as they are just like university classes and very informative. Pl make some video on ATX power supply using SDC 606p IC on hot side and SDC 2921 on cold side. I am troubleshooting it for no 5V SB and final power output. There is no shorting at both the sides.
What about using Hot Air Gun at 200C ?
yes
hot air at 200 - 300C is also good, but it produces some bad smell, i don't like that
Good go on

Thank you for the information, i have a question oh how to remove the black stuff on generator AVR modules?
if that is hard material then it is near to impossible, because that is epoxy based filling.
if that is some soft material then it is rubber sealant, that can be removed by slow heating and scratching carefully
What about warming up in water or oil?

using plastic tools for removing coating is preferred, as those are unlikely to damage the board.
How about using “CRC electrical quality SILICONE multi use lubricant ,( clear protective film, water proofs and lubricates)” on tv power boards

ne alâkası var dostum ?! bu güzel insanı üzme ! bir yolunu biliyorsan fikrini söyle ki hepimiz öğrenelim.
Might be it is known to you. But it was not known to me untill watching this video. Very helpful for me and might be for others like me.
@@tvbox8478 but there is no need to heat it up. This easily breaks.

I have bldc ceiling fan PCB filled with silicon glue....How remove that....Any solution?
Jim, now it's the time to stop putting Haseeb's personal effects into jello 😂

Podrías dar como rellenar la silicona con que producto
Using screwdriver for removing it has chance to cut the print track
Excellent thanks for sharing this informative video keep sharing
What a neat tip, hope I never have to use it as its still looks like an absolute pain
Make a video on how to remove IGBT Module Gel..
you need to replace the IGBT module. If you remove the gel, you will end up breaking the bound wires. Even if you can remove the gel, what are you going to do about the IGBT itself? Are you able to solder bound wires or replace the silicone chip? No!.

@FixDaily exactly perfect
humble thanks for your valuble and technical input

thank you. nice solution
Yes i recently removed silicon coating from washing machine board 🙄
Thanks....
You're welcome!
Good
Super sir
