Unfortunately Gerber EZ is probably the one thing I know very little about. As an FSE with Speedline I only had one client at that time that was using it and an application engineer came in and helped them with it. Sorry I can't give a direct answer

PB-free Hasl was not mentioned due to the following: 1)Equipment Convertion at the PCB Manufacturing side is expensive. 2)You are subjecting the PCB to Higher Temps than Std. solder. 3)Most PCB Houses are not going to invest in Two Hot Air level

In my case most of the PCBs are OSP finishing and worst case of MSD component on bottom side is level 3 (168 hours). You mean that PCB shelf life with bottom side assembled shoud be 84 hours?

I don't believe there should be any issues with the HASL finish. The issue is how long on the shelf and is a bake out required to remove moisture from PCB, as in any FR4 PCB's that may have had time to absorb moisture.

Finally, I chose AD to finish my design,and I thihk it's really fit for beginners.

Hi Jack, I once tried this finish ( without changing any process parameters ) and encountered wetting problems even in the first reflow process. It was thought as cheaper alternative to Ni/Au we use for planarity reasons. Heard of the same problems

We can offer two ways. We have a process control tool for OSP boards to validate the finish......but the dates yer talking may be best to take Daves F suggestion. NOW as far as the HASL finish goes...We may have your answer. We can Chemically revers

Hi Folks: We've been having bridging problems on our fine-pitch QFP's, despite thorough inspection of paste height, volume, and placement accuracies....profiles look good also. The bridging is happening after coming out of reflow...one last thing t

We are a small company, reletivly new to doing our own SMT (1 year) and we are having an issue, I think. We manufacture many board with no problems, but we have one that constently defeats us. This particular PCB has ENIG finish, and we have had th

Just to further explain myself a bit, and why I hate being bombarded by advertisements, is because I think others (sales and marketing people) are trying to manipulate me. Why do I think that? Say if you have 5 pick and place salesmen, 1 from Fuj
