Hi, been researching archives for PCB composition. Nothing much for what I want. Can anyone direct me/advise of PCB composition, and I mean the full works. Content of base materials, solder resist, chemical compositions of epoxy etc. Much appreciat

There is no IMC composition can be identified in phase diagram of In/Sn. There are some compositions such as In3Sn or InSn4 cited in earlier literature. Those composition should be regarded as approximate representation of solid solution of In/Sn. I

The BGA solder ball composition is 62/36/2 Sn/Pb/Ag, does any problem exist for the solder joint reliability? And what is the difference on SMTA process between this and the normal 63/37 ball?

SAC305 - it's just a metal composition of solder paste. All properties of solder paste depend on chemical composition of flux and other components - I don't know their names in English, sorry.

"Solder alloy compositions are numerous but the most important are still the tin lead solders which were used by the Romans. Tin melts at around 232�C and lead at about 327�C in the combination 62Sn 38Pb the resulting alloy melts at 183�C. This compo
