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

I have a supplier that want to upgrade all nails on a huge amount of ICT fixture due to test RoHS compliant PCBAs. My thought is that even if there are a very small fraction of residues left on the pins it will never go over the 1000PPM level. In fu

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

Hi, We have several fixtures for GenRad 228x tester and would like to change sensor plates as they are quite worn. The problem is that 3 fixtures have different plate sizes for the same IC, side length is 10-12mm. What would be the best size for sens

Guys, two things: 1 Fluxes have different probing chaacteristics. Consider broadening your horizons. 2 Look at SMTnet thread ... ICT Fixtures No-Clean Flux - Cartman 14:04:14 03/16/2000

Hi Making contact has been one reported problem, so some testers put in higher force probes that then might cause problems. If fixturing is done correctly, the OSP is done correctly, and test follows close in time after soldering little problems s

Kenny, Out of curisoty why do you need to paste the vias.Is it due to contact reliability at test.Can these vias not be soldered during wave process (if any).Can the Style of probe used in the ICT test fixture not be changed to accomodate these unsol

So why are you telling us about the solder bar? What is the flux? that is what you need to change, you have a rosin based flux it sounds like. you can change probes in test fixtures or change flux chemistries. Russ

No need to clean unless the sticky residue is an issue for you. If you are working with RF, it could be an issue. You may have probe contact problems as well with ICT and FT fixtures. We use a low residue flux for our wave solder machines (Kester

Most likely the depaneling is not your issue, but I do concur that there is some mechanical stress occurring somewhere. What about any fixturing for FT/ICT?
