Firstly can you advise me on the existence of the ANSI/J-STD-011
Secondly has anyone any information on the "potato chip effect".
As far as I can gather it is the stretching of the laminate caused by the
impact of the abrasive scrub used in the preparation of innerlayers for
photoresist.
I have recent;y come across a PCB assembly with a warpage which I am trying
to determine it's cause and I am trying to eliminate the potato chip effect.
Also note, when I baked the assembly, it somewhat removed the warping of the
board.
Can anyone comment on my situation and help me understand the potato chip
effect and problems it causes if present on an assembly board.
Thanks in advance
