what we are getting is open circuits not every BGA is failing we use Humiseal 1A33 and currently there is no masking instruction for around the BGA

we suggest as below : the first : check the soldering(solder ball and pad) by X-ray ; second: to do dye analyse (note:pls confrm is there have crack )

You're in the wrong forum. I doubt anyone here will have any experience with your type of issue (without researching it). Have you tried the dealer or a dealer related forum?

By tape manufacturer you can have up to two empty slots in the tape. That means you should have two retries after the first pick up.

Yes, I know all that, but I am interested in some real figures from the field. That is, what percentage of mispicks do you experience on average (for large runs, of course)?

We doubt that Humiseal 1A33 is causing opens in your assemblies. We'd guess the opens occur earlier in the process, but are not hard failures. So, you pass your tests. When applied, the conformal coat flows into the gap in the ball crack and insulate

Given that the LED work properly after being touched-up and that you don't have problems with other components, you may not be wetting the LED termination solderability protection during your normal reflow. Use a profiler to check the temperature on

Pictures are now located at http://www.stevezeva.homestead.com/ These components are 2W resistors that only see 1/2W at max. during normal use. I have contacted IRC still wqaiting for a response. The resistors were tested as good. But the circuit
