Jeff, The use of flux thinner would only add another chemical to the process. Environmentally, that would not be a good idea. My guess is that you would only end up with "thinner jelly" anyway. Alcohol works well on RMA flux. When assemblers switch f

Spanky, It sounds like you are looking for a recipe to use when you do get an assembly in that has 0201's on it. We have worked with our customers worldwide in the development of the process to use 0201's. Most equipment manufacturers out there

We have been soldering lead-free components on the products with SnPb solder for 10 plus years. Over those years, TI has shipped 20 billion parts with Pd solderability protection. Turn-up the dial on your oven and push on to other things.

Hello, we had similar problem in the past - when we had to change PCB supplier from a batch of hundreds of boards (NiAu plated, SnPb process) we got 2-3 boards with paste wicking to components leads what we did, was to check the thickness of gold on

I would certainly test the boards but from our experience, the vacuum sealed in room temp, no issues at all with our PCBs sourced from Suntak / PCB Founder / Fastprint / Yaxinda / JLCPCB well past the 12 month mark. We building boards purchased 5-10

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
