Just a note about cleaning stencils with a mixture of alcohol and water, especially if you're using no clean paste, it's really not recommended. Don't take my word for it, you can check with Alpha or most any other solderpaste vendor. What will actu

| Hi Guys, | | I am going to be graced with the good luck of processing microBGA's in the near future. A bit of a step forward from printing 20-mil pitch and wave soldering 0805's, wouldn't you say? | | So, any of you folks who have already experi

Maybe it is all what you get use to. Our assemblers like the vacuum pen. Since we do more than passive components, some parts would be difficult to hold and line up. As for as our Fristch, we use it as a manual and just have our bins on the side.

| I have received prototype PBGA (256 pins) devices from | Motorola (actual part number = KXPC850ZT50). These parts seemed very warped on the edges. When I put the part on a plain surface, it rocks quite a bit when I press lightly on a corner. I h

| Also the preheating of the board is done to help evaporate any water/alcohol that is in the flux - water is a big problem in No-clean processes. From our experience, a temp range around 200f - no more than 220f is ideal for the bigger boards, but t
