We have been doing BGA's for years now, and I would suggest updating your profile and place a thermal couple on the BGA, keep in mind the bigger the part the more heat it will need, We stencil print all of BGA's from simple bga's to complex ones, you

The question is that what do you want? An automatic/semi-automatic machine or a hand-prototyping printer? Using metal-sheet or complete (framed) stencil? Manual printing: For example, Eurocircuit's eC-stencil is pretty nice or there are cheap hand-s

"The question is: should we be looking at the operator? the paste? or the setup?" Yes. ;) Those guys love to brag about their 4 corner height adjustment on those printers. The fact is it's a PITA and shouldn't be necessary in the first place. It's

Bryan: * Most of our stencils are made from stainless steel that is held by a aluminum frame, attached with epoxy with a fiber glass intermediary between the frame and the stencil. * We use stencils to print either glue [thermoset epoxy] or solder pa

0402 Adhesive printing is possible with thicker stencils in order to allow mixed component technology. We have successfully printed 0402's with a 0.008" thick SS foil. Total material release is not achievable at this thickness, but not required u

My company is developing a product that will require solder paste to be printed on a piece of cast aluminum. The surface of the casting is not completely flat. It has been recommended that one way to work around this might be to use a screen instea

If we don't take SPI machine is given in the equation, another control should be put in place. Buckcho your approach is interesting, but requires a lot of effort. Do you guys think the stencil printer can count the prints for the same program? Or eve

We want to improve our process for accepting SMT solder paste stencils received from suppliers. Our process: * E-mail CAD aperatures to supplier with "readme" giving specific fabrication instructions to the supplier. * Receive stencil from the suppl
