Nope actually the whole bluetooth component is a raw part comprising of BGA and chip components in one small PCB wherein this whole assembly is encased in a shield. So basically when we recieve the part we can only see the shield and some minor chi

I tried MS2 for almost two weeks and I can see it works. MS2 is more a preventive tool rather than a solution to convert pour on top of the dross. Very important if you use this stuff is that you do the encapsulation of the wave, the bigger the surfa
