Hello I'll be the one to ask a dumb question--Why not fix the screen printer? If it is a MPM you can call me and I'll help if I can. And no I'm not trying to sell any thing. Better yet --why is the printer down? Wasn't thinking that you may be ou

Hi, We used the 1 mil for 0402's etc. Admittedly most of our experience was on 2.6 & 4 mil as we mainly used the GSM's for oddform & fine pitch, but we found that the smaller chips went down better & more accurately with the smaller camera. Oh yeah

Thanks Fastek. Hi Pete, It was a production related question - I'm tired of being shafted by manufacturers & overcharged, so instead of spending months trying to beat someone down on price, which may in the end be fruitless I thought that the most

Why does my solder joints look so wrinkled?
