Hi, Does anyone know about the epoxy push test specifications for the SMT chips component. For example: 0603, 0402 and 0201 chips. As usual, your help is very much appreciated. Thanks in advance, Nell

You mean the destructive test were you continually push on a part until it breaks free from the board and flies across the room?

Look like no way you can measure after glue printing. We have been running glue printing for about 2 years and using the "push test" method for testing the strength of connection of component and board. I don't see any problem. For component ( 0603 &

We have talked about testing the cure of glue, epoxy holding secondary side compomponents in place prior to wave soldering several times here on SMTnet. Search the fine SMTnet Archives, if that's what you're seeking.

Dear all, Is there anyone who has the experience in conducting Push&Pull test for fine pitch components?i.e.SOIC,QFP. The customer clearly stated that,"every lead should be tested for selected components".but, you know that,the fine pitch,0.5 or

Ooops, my bad. "Curse your eyes Nell, for even asking a question on this forum. Check the archives before we put a curse on your adhesive process and force you to ask another question!" Whew, hope that made up for my mistake.

Sorry Nutty. But then again, this coming from a guy who used to answer in Ebonics, makes me wonder why.

So far I've been working with a xtal. I've been placing this on a board and the part was falling from the board. We found residues on leads and notified vendor as contamination, after that 100% of our production has been verified with a perpendicular

Slappy The level of rightous indignation is well done, but sarcasm seems a bit overdone. Just a twinge of it would have been fine. Needs some work. Good shot at it though. Yano, maybe the 'cursing of eyes' bit was a little over the top also. Po

Grind the point on a pogo pin from an in-circuit test fixture flat and push on a leg of the component till it bends, mark the deflection, then add about 30% to the length that the pin pushed in (maybe more if your using no clean and the residue adds
