You're barking up the wrong tree. Solder "splashes" are generally caused by your print being off pad a bit. They are called solder fines. I've never seen a placement machine have the capability to push paste around using it's kiss-off from the noz

I'd like to print out a forum item to fax to a friend who does not have internet access or email yet at his new facility, but no matter what I do to my printer set-up I cannot get the full page width to print. The right side of the message keeps gett

Thanks for the answer. what i believe happent is that the manufacturer of the paste reduced the tackiness of the paste to eliminate the squeegee sticking problem, and now with the reduced tack its a lot easier for the powder particles to break off du

Dave, Why on earth would you want to use a stepped glue stencil?. If you print slightly off contact the hight of your glue deposition will be roughly half the width of your adhesive aperture width so if you want a 10mil high deposit use a 20 mil ape

I need advice on a pad design which several other engineers whom I work with would like to try. I think it is an utterly crazy but I can't seem to convince them differently. My current 0402 chip pad sizes on alumina and FR4 substrates are .022"X.

We r using QFPs of 0.5mm pitch and r not getting any soldering prob at the end.But some new customer insists upon the thickness check of the solder paste after printing. At present we don't hv thickness checking system.We r controlling the amount of

We use Zebra printers 170xii. If you buy used you can get them for a relatively low cost ( couple hundred $$). You will need to find software to work with the printer. We use Bar One. Brady Labels supplies a full line of thermal printable labels & ri

Hi Umar, I believe you either are over printing these pads or the alignment of board and stencil may be off. Check your print right after your screen printer to verify either. If you are not over printing and your paste alignment is spot on, then
