But if you’re making a PCB that requires high quality and especially accurate drilling, like the ones I made for this bed-of-nails test fixture, you should absolutely use Laen’s OSH Park ...

In-circuit test (ICT) systems have been the leaders in using electrical means to look for structural defects in PCBs. They employ bed-of-nails fixtures to provide electrical access to as many as 7000 ...

If PCBs aren’t tested, errors and defects missed during the manufacturing process could eventually lead to malfunctions and product failures in the field. After a PCB board is manufactured and ...

Bed Of Nails And Accuracy In PCB Manufacturing September 11, 2012 by Brian Benchoff 43 Comments A few days ago, we mentioned the new ARM-powered Teensy 3.0 project on Kickstarter .

Today, little has changed. Test engineers must deal with denser circuits, eroding bed-of-nails access, higher speeds, and lower voltages, as well as the migration to lead-free solder. Yet, supporters ...
