Has any anyone established / published quality standards for BGA solder joints? Is IPC-A-610 in process of adding standards for BGAs?

Hi Guys, (Note: We are not talking about bill-board RES/CAP, we are talking about Z-axis slant/tilted RES/CAP with respect to the PCB pad Z-axis plane). 1) We ref through the IPC-A-610C specification "bible", and can not find a "chapter/verse" tha

How about section 12.2.12 of IPC-A-610C? It doesn't include detailed description of root cause/effect but acceptance criteria.

Can anyone tell me what parts on the pwb should be protected by the conformal coating, and what parts can be free of the coating (such as the areas without components, traces, brides lands)? we were follow MIL standard 2000 and IPC-A-610 class 3. Tha

J-STD-001C, Table 11-1 is a good starting point.

Bow & twist for bare boards and panels: IPC-A-610 1.5% for PTH only and 0.75% for SMT. So, what are you doing to these poor boards to make them warp?

Hi, We would like to know on the IPC-A-610 rev. C standard for acceptable and reject criteria, do we have to satisfy all that are listed on the manual or either one will be OK? Thanks for all the assistance that will provided. Dennis1

Dennis: The IPC-A-610 requirements are seperate. * You need to meet all acceptance requirements, in order to be in compliance. * If you reject a part for any reason, you are not in compliance.

7mils/inch is 0.7% and the IPC-A-610 calls for 0.75% (for SMT), so both are approx. the same. So there are no two methods in what you described. The 7mil/inch is also a percentage. Regards Vinit
