Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

The answer for us at my previous employer was water soluble flux. Wash the board, no residue. If you're not set up to wash (needing a washer, DI water source, waste treatment, ventilation, etc.) it can be expensive and space consuming. Do some resea

Graham: Maybe a twist on your comments, I don't believe that people understand the true cost of using no-clean. Dave

I had problems with very simple timing circuits in the kilohertz range with leadfree NC solder pastes. Never saw the problem with lead NC solder paste. Run lead free no clean and clock was off. Run lead no clean and clock was right on.

I have a customer who runs A-D applications with 5GHz analog and it is 100% no clean. The only answer that will be acceptable is what works for your circuit design.

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �
