Yes, we use solder paste,solder bar and solder wire from different manufactureres for 1PCB assembly. And, what JAX said, we never mixed solder paste from different manufactures and used.

Will the flux residue from solder paste A come into contact with flux from solder paste B? If so you better do some tests. There is always a possibility of a bad reaction between 2 fluxes. You need to test to make sure. Jerry

I have a question regarding mixing different manufacturers solder pastes. We have a board being built by a CM that we are bringing in house and soldering a final cover onto the PCB. The contract manufacturer is using solder paste A. We want to use

Who Cares... Mix Away! Although you should not mix different Solder Pastes' together in a container or on a stencil (Mostly due to the flux, although solder sphere size and shape could cause an issue), mixing solder brands or chemistries on a board

Guys I have a question since the ever present problem with the crack switch we had to change to a low temp lead free solder paste in these case eutectic 58Bi/42Sn and 57Bi/42Sn/1Ag alloys, now the main question whats diferent between these one and th

SAC305 has a liquidous state temperature 217 degC. Check the datasheet to compare to this temp. I suppose, it may be lower. - Cheers !
