We currently use Loctite 348 chipbonder to secure large parts that will hang under the board when reflowing the second side. Rework has been complaining that they sometimes have to remove those parts to make repairs and it's difficult to remove them

We are mounting an microphone device (SMT package) onto a PCB - how? Surface mount line or hand soldering? Contamination can only come from the solder paste, solder wire, flux, or burning the component/PCB assembly during hand soldering. Unless the

Have you considered using PCBSYynergy for the CAD conversion and bypass the gerber step. Then add in Programming by Ealead. https://ealead-e.ucoz.com/index/products/0-8 https://pcbsynergy.com This ends the breaking of QC by bypassing human process

We have a customer that at one point had a dozen LED boards that were all very similar in size. They used Aluminum boards and I found that the difference in thermal mass between the assemblies was negligible considering the largest difference was ac

I am facing a ppm fluctuation issue. The customer provides a limit of 600 to 1500 PPM in the Reflow process and it should be under spec. But we are facing the issue during the running production and the ideal state ppm flucate sometimes goes below 6

We don't own one, I'm a bit interested to see what you end up with. We do have a triden pcb wash, and I know Aqueous Technologes makes a lineup of misprint and stencil cleaners. We had an engineer in from Zestron chemical company, and while they don

Unfortunately no sample numbers. We are building our own products, not a contract manufacturer. We are monitoring AOI, RMAs and rework - this only started in the last couple of months, but top management inclines not to give a target as it may "upset

I hadn't suggested the IINEO's because as a step up from Neoden's its a huge leap in price and perhaps around twice the price of the AM100, that gap would narrow as you purchased even more feeders. If you have a big product mix or are a small batch
