When testing components on a PCBA, try to validate coverage for presence, correct, orientation, live, and alignment. AOI is not really great at catching cold solder joints and damaged components, and from my experience an X-Ray is only as good as the

Our ICT Guy here at my company loves to use lots of via holes as test points - via holes which are 0.040" diameter, and spaced at 0.004" edge to edge spacing! He doesn't like to tent the via's either, so I always battle via-to-via shorts at the wave

Surely this is a job for Wavemaster Larry? Have you tried flux buster pins in your ICT yet? They are quite good at cutting through the crap on a board.

Regarding X-ray I was referring to ssager's comment "...X-Ray is only as good as the human eye that is operating it...". I thought x-ray images could be checked by software algorithms to find defects, not only human eye?

As the article eludes to, you still need probe access to measure the pins with TestJet. One thing I wanted to add was the use of JTAG for use with Boundary Scan. Certain devices have JTAG capability, but not all JTAG devices are Boundary Scan compa

With TestJet technology, if we want to test a 64 pin BGA, would we need probe access to each net of the device to get full coverage? If not, would I only get coverage to the pins that have probe access? In a nut shell, How exactly does it work?

Samir, From experience, the only board test situation where tented via's have difficulty with contact is with a Flying Probe type tester. Otherwise, for traditional ICT, the force of the pogo pins, correct probe type, and fixture design should do th

Hi there. Sorry I haven't responded sooner. The video I posted was a very preliminary trial that I developed as an option to my BoMCompare application. BoMCompare is a tool that can compare Bills or Materials of various file formats (xlsx, csv, txt,

| There is a practise within the industry of an Inspector inspecting a board, and that same Inspector performing touch-up. My opinion is that the Inspection and Touch-up operations should be separate functions whereby the Inspector is not performing
