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

Both conditions are acceptable for this bottom brazed flat pack package. The solder coverage must be within 0.070 inch of the lead/package interface per MIL-PRF-38535, paragraph A3.5.6.3.4.a. While that requirement could allow for a gold gap near t

Juan, I believe in term of height vs volume, volume is much better control. By the way we used Cyber Sentry 2000 which allows us to measure volume, height and area. My plant normal practice is measuring the height. Last time I did the control limit

There are several life studies (see for example http://www.solder.net/stencilquik/articles.asp) which point to higher reliability of reworked BGAs using solder paste vs flux. The theory on the mechanisms which allow this to happen are as follows: 1
