If you are just prototyping, I would probably go with the Jet printer(I think the paste cartridges are very expensive). If you have some casual runs I would use a stencil printer. Actually I would like to have them both - tweak the paste amount with

I knew jet printers where slower but I not that much slower. Right now I have a old Speedline Tech that Im looking to replace. Since Im new to this industry, Im cloudy on which companies make a good quality machine. I have a mydata pick and place, s

I'd also be interested in seeing what the OP went for too. We're thinking of upgrading our MPM3000 series. Has served us well over the years but is a bit dated to say the least. Not heard much about the SJ Inno. machines here in the UK. Would prob

I can buy approx 1000 stencils (cost includes next day delivery) for the price of a MY500. With a stencil, I can use WS paste and any other paste for that matter. The MY500 only jets certain paste from specific manufacturers. It is VERY VERY rare th

I do a lot of prototyping, but I also do production boards. I produce 2000-5000 boards a month for an in house smt process. I feel this will increase do to the fact that our engineers are designing more with surface mount rather than through hole. S

Welcome Jimmy Let's mince words to help focus on the issues. When you say "QFP area solder paste shifted," do you mean: * Paste printed on land pattern perfectly, but moves after printing. * Paste printed off the land pattern, even though the stenci

Thanks for the suggestion. The large ground pad appears as a single large pad on the component and PCB but we print a matrix of 28 small dots of paste to provide the solder for the joint. The inconsistent volume transfer can occur on any of the fo

Hi We are running automatic stencil printers, open squeegees, stainless stencil, stainless blades, print speed 25-30mm/sec. We have a frustrating consistency issue printing .37x.3mm apertures on a 45pin LGA (11 pads each side, 1 large ground in mid
