one of our customers is asking:
a) what is the "standard" designwidth/length of .020 and .025 mil pitch
QFP pads ?
b) any data / experience out there how variation from this standard
might affect soldering defects / shorts etc.
Can I reduce defects by reducing padwidth ?
appreciate any and all input / Thanks
