OK I know it is funny to have two different PWB/PCB processes, one for pre production and one post production yet it is possible if controlled and implemented in a strategy. In debug if your company's experience has been for a repeated need to do IC

Anyone have an idea on what the smallest feasible/reliable pad size and pitch should be for a PCB designed with an array of ICT test points? Thanks in advance for your help.

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

It sounds like you may be thinking of two different test methodologies. What is required? Bare-bard testing, to verify pcb fabrication? Or populated board testing, to verify manufacturing? If it's bare board testing, the fab house should advise a

do you intend to use Immersion tin as a PCB surface finish ? Then Whisker concern is as below if you do not past your test pads, the pads will be stressed when probed on a ICT or a flying probe tester. This is a POTENTIAL for whiskers There is a lo

At an EMS I used to work for, our process for first article inspection was to have a human technician do a point to point comparison between the BOM and the PCB. They would verify component part #s were correct per the location, correct polarity and

We are already using ICT on the PCB, which should catch most missing components, also components installed backwards, or the wrong value(to a point - we do RF so we have lots of very small value caps and inductors which can't be measured), and in som

Hi Larry, Picture a old lady with a set of knitting needles with leads attached to them, pressing the needles into different points of the PCB (pads, test points or component leads) and measuring resistance, inductance, waveforms etc between these p

Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste
