IPC-A-610D Sections 3.1, 3.2, and 3.3 and Table 3.1 specifically mention compressed air as a source of ESD damage

Has anyone ever run across a specification for the sheer strength of a soldered BGA assembly. We are looking to qualify a process and would like to have a target number to shoot for. Thanks

Thanks for sharing your work experience. I found a reference material with IPC standard (IPC 610) that specifies an exact heigth that a capacitor needs to be placed, I will check this standard specifications in more depth.

We know of no specification, but there are guidelines. Don'ts of Better Flexible Circuit Design and Manufacture; Mark Finstad; PCD&M; 01 June 2007 http://www.pcdandf.com/cms/magazine/95/3556

I am looking for a company that recycles the scrap created when boards are depanelized. Specifically for CEM3 Material.

Dave can you be more specific on this? I will be interested to see such a picture from cross-section with an oxide layer. Is this possible? Thanks in advance. Nicoleta.

Thank you Noid, Is the baking process product specific are they any guidelines/standard procedures? Any recommendations are appreciated. Thanks, David

We guess the nickle has a rougher that normal finish AND the gold is at or below your specification. The nickle bumps are poking through the gold and are oxidized, preventing contact with you ATE probes. If this is correct, it would be interesting

1 um". Some PCB manufacturer is telling me that this specification is not feasible in production. I would know if this position is due to the equipment (or process control) they have, or if in effect is not possible to satisfy my requests.

Follow that same link I gave you for the sample files, there is a zip of a file transfer utility specifically for these machines. (I sent you an email, too) Enjoy, Tom
