Apoligies Steve if I did not explain myself clearly. We have made the same design using the same RoHs compliant components (which I am assured by the suppliers are process temperature capable) with both lead and lead free solder. Without wishing to

Although greatly publicized and many papers on the subject, I wish to hear experiences from the field from professionals who have migrated from SnPb wave soldering to PbFree wave soldering. I am being pushed by one of my largest clients, an internati

Hello, I'm having problems with voiding on an assembly that has a GPS hybrid with balls much like a BGA. This is a RoHS assembly using no-clean solder (Kester EM907). The voids are at or above 25%. I use an 8 zone oven where I peak in zone 7 and

Hello, I have been recently bringing a new RoHS wave soldering machine into production. Unfortunately, I am finding many of the boards are experiencing blow holes. It is always silver plated PCBs and I believe it is related to moisture ingress. I n

I purchased, ran, programmed, and maintained a RPS slide for a number of years and can't say that I had any major complaints about it. It ran well as long as it was maintained well (which is no different than any other SS I've worked on). Support w

Steve, Thanks for Your replay and I agree with You. But sometimes I find it hard to always have the optimum in every aspect of our high mix/low volume electronics assembly production. We also do a lot of prototype production. In this case we had to g

It is not OK to use leadfree BGA's with a lead process. Other parts "should" be reverse compatable. But I first saw problems over 5 years ago with Paladium leads and a lead process. Don't confuse saying "it's ok to use lead free parts in a leaded p

I have used a 2006 Electrovert Vectra ES (63/37) for last 3 years, we acquired it used. It had little or no maintenance before we got it, now after replacing a solder pump motor, preheater fans and thermocouples it is pretty reliable. The spray fluxe

Hi, The verbiage states lead finish on components and not solder used in assembly. I have found nothing that states that Swatch got an exemption. Although the 650 micron pitch spec seems to have come from the data Swatch presented in their execpti

Thank you Davef, If I am not wrong in understanding, your answer is mainly related to the Legal point of view according to several different Countries who adopted Rohs or equivalent. My question, sorry for my poor English, is mainly related to the
