You will have to be more specific about your boards and process to get any help. There are many different types of in circuit tests and functional tests throughout the manufacturing process. The nature of these tests depend on board function. Sinc

test at the bare board level consists of opens and shorts. It makes sure that all traces are hooked (connected) up to the appropriate place and they are not shorted to a non common conductor. Russ

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

We always have the board house do it. Why catch bad board for them? Don't let them push you around.

Your process makes a bigger difference. What I have seen is ICT done early is better than AOI done more than a half shift later, and AOI done early is better than ICT done more than a half shift later. For high mix/low volume, I would go with AOI whi

We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

| | |Hi all | | This Debate on lead free soldering is really hotting up here in Europe. From 2004 the use of lead in components and assemblies will be banned here. Also flame retardent halogens will be banned(FR4 etc). While we all agree that we hav

| Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a me

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
