Relying on AOI for sensor boards - EOL for functional test

Electronics Forum | Mon Jul 30 12:45:00 EDT 2018 | mdkmdr

Trying to get a sense of the push-pull going on between designers and manufacturers on the subject of 'one test point per net'. Getting a feeling like the new paradigm is doing all of the electrical tests as functional at EOL and relying almost comp

Depends on what sort of outfit you are working for, and what you are building. A lot of CEMs are doing Flying Probe or ICT on the boards ahead of investing time building into units or adding parts that prevent access to rework. We have a combination

What's the point of such a test? * If you are operating a board in an environment that keeps the board at a temperature that is close to causing delamination, why not design a board that can tolerate such an operating environment, rather than contin

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

Is there a test to check for delamination on a pcb? We are looking at new board houses and along with our standard solderability tests my boss wants to test for delamination. thanks, pr

Contamination test

When carry out the contamination test,do we measure for Chlorides on water soluble and No-clean fluxes? 1) What is the equivalent factor for machines developed to test the board cleanliness, Omega-meter vs Ionograph vs Zero-ion. 2) What values do we

Richard, With respect to the Resistivity of Solvent Extract (ROSE) test, the test solution is exceptionally aggressive. With the Zero-Ion for example, the test solution�s resistivity is 150 M-Ohms. Additionally, because test solution is made up of

Hi Richard My experience with R.O.S.E. testers has been positive with regard to detecting ionic contamination (even exceptionally low levels). As previously mentioned, a good R.O.S.E tester will be able to detect minuet levels of ionic contaminatio
