We had a similar problem with lead-free through-hole components. We baked those baords to remove the residual moisture and everything went to 100% pass - defect was gone. Couldnt hurt to try a sample run while you decide if the PCB holes need to be

Hi Davef, Thanks for the reply. There seem to be no issues on SMT reflow based on some samples done. We have not stripped the gold yet. We did a X-section+EDX and we are seeing traces of copper on the nickel layer. Any idea what is the implication of

Without understanding machine loading, we'd guess that your current "every 30 wave solder day" sampling schedule is fairly conservative. Consider approaches to better understand change in the analysis results.

your comments will be appreciated, please; IC tests have been performed on two kind of Raw PCBs (HASL) samples by adopting three different methods : First Sample (supllier A) - Omegameter 600 SMT, solvent=40�C: extratcing time 10 min result = 0.2

Could anyone recommend an esd safe masking tape for conformal coating that does not use a silicone based adhesive? I have looked into 3M's 7419 series and am awaiting samples, curious if there is another brand out there people have used. Thank you

Hi everyone, Is there any instrument that you are using to measure the tensile strenght of a solder joint?. I would like to measure that from smd and thru hole parts. I just want to take a few samples to verify the mechanical properties. Thanks

You may want to try C8502 from Kyzen Corp. I use it on our three wave solder machines with great results diluted in DI water 50%. I am an end-user like you not a sales person! You can order free samples... -George

we should assemble 24000 of this board so we should find another solution and we get three sample of this part and all of them has this problem , and now we dont have time to wait for new part to come.

Hi Dave, thanks for the info. I'll check the detail and try to send sample SMD's for test. - Bong
