If you are a CEM you are setting yourself up for failure and will be left holding the bag. Flash gold has one purpose. It is a protective coating for the base medal to keep it from oxidizing. It is very thin and will be absorbed into the solder joint

I am posting this here because I think it may have something to do with PCBA: I have a simple battery-powered consumer product (LED light) that we have been manufacturing for some time. All of a sudden in one batch, we have about a 4% rate of a sing

Where can I find typical failure rates for wave soldering ? Thanks, Dorin

With all "tricks" applied, expect failure rate of 1-2%. HS failure rate is somewhat lower.

6/400 per week seems high? 1.5% failure rating, technically close to 75% annual failure rating. Is that normal for other manufacturers?

First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

Hi, If the failure rate is a lot higher than all the other components including ones similar to the 0603's than you won't be making a big deal. It is all relative. My only thought is to run a DOE with 0603's from different manufacturers and see if

One of our customer wants to change the process from OSP boards to ENIG. His question was: what is the failure rate for ENIG in the last 3 years? well...what to say? I was suggesting a ImAg instead of ENIG. But..nope. Any ideea about this topic? For

Hi, I was looking for information on failure rates for BGA components. I am analyzing our BGA rework rates and find it difficult to define a root cause when a remove and replace of the BGA component corrects the test errors. Inspection prior to re
