We have seen this same defect. Led's not blinking during test and some tops popping off. Ended up being an msd problem. most of the lite-on components are msl level 4-6. We now bake and track them no problems seen in a while.

We believe that it's perfectly resonable for you to define the cleanliness that you require. We recommend that you leave it at that and not define the process or materials that your supplier use in meeting that cleanliness level. Start with a dirty

If solderability is the only concern, then there is no standard time. Multiple factors involving OSP thickness, Flux activation levels, profile parameters, storage environment will drive the problem. You just need to perform tests to determine your m

I don't have an answer but I am curious. What data/testing shows that this voiding is detrimental? How did the auto industry arrive at

Large and small levels, chalk line, plumb bob, pallet jacks, johnny bar, a 2x4 + sledge hammer, and a couple of the same PCBs to test transfer between machines.

Hi James. I do not work in sales. I am a ME in CM....for over 18 years. If you do not have resources to evaluate wave machines should we assume you have limited support resources for your current machines? IF this is the case buying an entry level

What do you mean by "new information"? On final module testing: * If you have hypercorroded nickel and you detect it during final testing, you'll notice it. * If you have hypercorroded nickel and you don't detect it during final testing, you'll ship

I'm afraid we don't agree regarding the best test method to use here. My understanding is as follows. The omegameter test measures board-level, ionic contamination (i.e., average for the entire board area and all components); it does not tell you w

Kelvin, Yes, we're referencing the same spec. I performed the test under the Class 2 conditions (except that I used a 100V bias rather than 50V...but my water-washed microBGAs still passed). Regarding the omegameter test: we have this instrument,
