Peter: Please explain: * You say, "The cooling phase is important to perform the strength of the solder joint." [We agree that fast cooling rates produce fine grain in solder and that fine grained solder connections are stronger than coarse grained.

Hi Patrick, With all due respect, it is easy to quantify zero. You made a claim that your flux produces ZERO residue. There are several industry-standards (IPC and Military) of determining the cleanliness of post-reflowed circuit assemblies. Th

J Rose at EMPF says: The introduction of no-clean solder fluxes in electronics manufacturing has given rise to greater levels of solder balling simply because the opportunity to remove them in the wash process does not exist. They are typically cause

Does anyone come across the problem of pcb turns yellowish color after going thru' reflow under ROsH condition?

Hi Ktron, I'm still waiting for my supplier to get back to me on the type of finishing. Usually what type of finishing is recommended for reflow under ROsH condition?

Hi Davef, I'm suspecting that too! The recipe we are using is the optimum for good soldering results. I'm checking with our supplier on the type of pcb material. Do you know the recommended material for pcb undergoing reflow, under ROsH condition?
