When carry out the contamination test,do we measure for Chlorides on water soluble and No-clean fluxes? 1) What is the equivalent factor for machines developed to test the board cleanliness, Omega-meter vs Ionograph vs Zero-ion. 2) What values do we

Is there a spec for the adhesives used to hold down parts before wave soldering. What size dots are recommended and what is the maximum shear force(1LB?) tested for to ensure good adhesion. Your help is appreciated Rich Scheleski

As a basic guide the minimum spec you should look for is 500g you should achieve a force on most chip parts of 800-1000g. Parts are lost on wave soldering due to no material, poor curing, poor surface adhesion and poor handling. Its not the wave sold

Hello, I've been evaluating a bunch of wave solder fluxes and found one that is absolutely perfect. I'm so excited I can't wait to switch over. Unfortunately, I have to assure reliability, and the only test I have in-house is ionic contamination

Chrys, Please, refer firsatly to J-STD-001 Appendix D. Now, consider: SIR testing will help define the reliability of your finished assembly - it will not tell you how clean it is. Which do you or your customer prefer? Present SIR testing de

50% of seeing it in a single pass. The only time we do this is if we have a board off the line that has delaminated. We'll run a sample of boards through bare to confirm that we have a bad batch. Even if we see no failures on the bare boards, we'l

Are we talking pushing on leads to see if they come loose?

I have heard the term as both green stick and orange stick, but yes, pushing on the leads to detect un soldered leads. The amount of force is subjective. Any thoughts on this is appreciated.

Are there any write-ups anywhere? My boss wants to show a customer a write-up. I"m checking IPC specs but havn't found anything. I think almost everyone does it but is not a published standard test. I hope some organization has written it up as a st

So I am having a little trouble with my mydata MY19. its an older machine picked up used and its had its quirks. recently we tried to start adding electrical verification to our workflow, and had to disable it as we were getting intermittent bad pa
