As Ioan says,These components usually come in tubes rather than trays. I can understand why you might want to do this because I have one very low volume but complicated board that has seven programmable PLCCs that I just don't have room for on the m

Per our staff here at ACI......... Higher Temperatures maybe necessary to achieve good solder process results. The alloy formed when HASL coating protects the copper is the same as that when OSP provide protection. Temperatures may be increased to im

Are you changing heads because of pastes or just changing widths ? Changing the head w/o cleaning is fairly straight forward. (Actually it's Pretty easy.) We have two widths - 8" & 12". We switch twice a day with very few problems but, we don't have

Some earlier machines with mechanical component alignment could be bought with electrical test options ( Mydata, Siemens o.a.). This is, to my knowledge, the only method to identify chip components prior placement. The downside was a high reject rat

I think the 1st option would be the best. I have found that a touch up person WILL TOUCH UP SOMETHING, regardless of the electrical needs of the board. This leads to a lot of unnecessary rework of joints. I would hope QC is tracking the defects and t

Hi Rob, I'm not sure if you're kidding or not Are you moving to Australia? Here's a link to the text John Burke used to write the EU commission for an exempt on lead in solders on environmental grounds. (Supporting documentation links on the bottom
