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

Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng

We currently build a product that uses RS485. ICT is geared very well at testing serial channels, as long as there is a way to synchronize the transmit and receive lines. But in the case of a simply RS232/485 protocol, simply doing a loopback test

ICT and AXI are two different methods for MDA. ICT checks component values and polarity- component and circuit electrical testing while AXI checks solder joints- volume, voids, bridging, etc.... Typically, AXI is in the SMT process engineering and QA

It's a test technology. It's quite different from either ICT or functional. It's also called boundary scan. The board has to be designed for it. You basically plug the J-tag tester into a port built into the board. It has it's own special niche b

We are looking into purchasing a Falcon ICT/FCT from Digital Test. Does anyone have any experience with this company or the machine? 1) How would you rate their technical support? 2) What are the functional test capabilities of their machines (pr

Is there any official or in-official in-house standard for ICT pin maintenance on volume boards? Like, how many test can or should one pin do? Currently we just change when we get contact problems. That probably after 5000 tests or so. But I guess

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

Hello friends , What is the extent of Probe mark allowed on a assembled board ? Is there any related material on net or standard .Recently we had an issue where the ICT was done and the joints on which the pins were tested had dents on the joints

Chances are this is not a component failure. First, these are passive components with passive testing on the ICT. He may have guarding issues, but more information is required as has been stated. Are all capacitors with the same P/N failing in dif
