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.

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

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

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

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

We recently decided to try using a different source for our bare boards to save money. On two different batches of PCBs now from the new source, we are seeing beading including some serious enough to short out underneath 0805 parts. We have never re

the cause could be moisture in your pcbs. To check it...pass some bare pcbs through your reflow oven (this is a simple way of drying them out a bit), then paste and place and reflow as normal....if solder beads disappear then the pcbs have too much m

TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s

I am pretty sure that will vary on the paste manufacturer. Using different amount and composition of flux will give you some different viscosity. I evaluated different solder paste brands before and I can tell you that some of them are very runny com

We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to bu
