Hi everybody. I'm replacing the mainboard on a mavic mini 2 and I found that there was black metalised tape stack on the underside and the sides of the main body. It looks as though it was used as heatsink for the components on the under side. Looking around on mainboard replacement info, there's no mention about it. Is it fitted to all mini 2 models or maybe to some? Any ideas any body and if needed do you know of supplier?
