Is anybody using IPC TR-640A? This is a troubleshooting checklist for wave soldering. Is it worth looking at?

We have TR-460A. We do not use it very often, because of the level of experience of our troop. It is useful for companies looking to develop, structure, and organize their wave soldering process troubleshooting skills. The information in TR-460A is n

Can anyone point me in the direction to find some IPC standards for lead free solder joint reliablity tests, such as shear tests, pull tests, vibe tests, enviroment tests, etc. I need to know what the specs. are on all aspects of reliability and how

You're correct. There is no criteria for no-lead, but there none for SnPb, either. Solder joint strength in pull/shear will vary with lead geometry, solder volume, lead metal/metallization, the way the test is done.

Hi Ben, IPC610 has a pass/fail of 25% of ball volume. Hope this helps

Hi All, I am looking for some DFM for wave process. Is there IPC standard ?

No need to make such a document. It is all in IPC 610.

I am in the process of making a requirements-document for manufacturing of a PCB. I would like to state some requirements for maximum allowable component shifting in the final PCB (both displacement and rotation). However, I can't find any (IPC) sta

What exactly do you mean by component shifting? If you mean lead over hang, i.e, how far off the pad can a component lead sit and still be acceptable, IPC 610 addresses this.
IPC is the trade association for the printed wiring board and electronics assembly industries.
