This alignment procedure allows for a more efficient Automated Assembly Process via Pick & Place machines, and the same benefits are observed in Solder Mask application. Weld Pins. These pins on the bed of nails should be conical at the tips and longer than the pogo-pins so the board lines up BEFORE it makes contact with the test. It may be difficult to line up a large number of pins all at the same time. Manual silkscreen printing: This is the standard method of printing markings on a PCB by using a stencil as a template and pushing a non-conductive ink through a polyester screen onto the board. 087" thick, these holes should be at least . Avoiding the use of the alignment pin option (typically shown as "-A" in the part call out), to minimize the impact on the alignment tolerance analysis. Plugging PCBs into backplanes is a fairly common thing so there's a good range of options out there. That’s a square with sixteen pins that are spaced maybe a half of a millimeter apart with a center ground pad. Terminals for Probes - FNP Series. 16 inch (see sheet 6).
