Many people use the same spacing [and pad designs] as they use for primary side SMT. We don�t. DOWN STREAM SMT-TO-SMT SPACING: In addition to proper orientation, components cannot be immediately upstream of terminations that are to be soldered or b

I'm sure the parts and solder paste are well registered. these transistors are commonly to252 package,and sometimes to263 package.I 've a picture of these two diffrent kinds of pad patterns of to252,but i don't know how to post it here... Thanks ®ard

IPC 2221B mentions a minimum clearance of 0.5 mm between adjacent holes. A drill-to-drill spacing of 20 mils is a standard value in manufacturer design rules. For small annular rings and pad-to-pad clearance, the minimum via distance is often defin

Dress From -> Dress To -> To "From" and "To" are pretty obvious but I have no idea what "Dress From" and "Dress To" mean. The wiring list is presented as a grid. Each of the categories above are represented as columns. Every row is a "run list."

Anyone out there have a source of information on the type of terms and conditions a subcontractor may use for a printed circuit card Build-to-Print job?
