What kind of ict nail should we use when testing a board that does not go through wave solder? There is no dome shape for our nails to "bite" into, and we are having problems.

Bluto: Either: * Give the springs in your probes some spinach ... OR * Print some paste onto your test pads Popeye

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

In-Circuit Test is the best method for ensuring solder joint connections. It is a much more reliable than AOI. An ICT machine can ensure solder connections are made for array package devices such as BGA, PGA, etc... AOI is best for component I.D.- is

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

In circuit testing is expensive up front because of the fixture cost but the tests are fast. AOI programs can be develpoed in less than a day but take longer to run. If you have good test coverage, in circuit would be a better choice in my opinion-if

When we first got into BGAs on ENIG we were getting joint cracking at in-circuit test. The joints were breaking in the Sn-Ni intermetallic. We did a lot of pull testing while working with our board suppliers and our conclusion was that pull testing

First, I don�t understand why your board fabricator can�t do a good job plugging your vias. Additionally, when you consider that they forgot to plug the first batch of boards, it makes me wonder if they are desirable as a supplier. Generally, we us

I have used all of test and inspection techniques available out there: AOI, AXI, Flying Probe, ICT, and FCT. The reality is that they all have a place in manufacturing based on the type and complexity of product you bild, the industry it is intended

Hi It's me again. Our products need to pass a chamber test 45c/36hrs after the PCBA completed batch of functional tests and assemble in to case. We found 1 unit was functioning for 24hours in the chamber, but hang after that. We tried to re-boot the
