The 10k rebuild does not need to be applied every 3-4 months as previosly stated. A cp machine that is running 100% of the time on a 24/7 basis will tack up 10k hours in 12.4 months. Now we all know that this is impossible due to parts shortages, pro

650 Standards are also located in the back of IPC JSTD-001. I am currently looking at 4 pages on bow and twist. Percent bow = R1-R2/L x 100 (R1= Highest point; R2=lowest or resting point; l= length) Percent twist=(R1-R2)/(2xL)x 100 Sorry if this is

Dougie- We,too, have the IPC-A-600F, and the spec. refers to IPC-TM-650 test method in the back of the book. Look on page Number 2.4.22 of the test methods appendix. This outlines the procedure for determining the percentage of bow and twist,

My steps are different in that case: 1- Check mounts. Try to adjust origin point until get the pretty good mount positions. 2- Teach fiducials ( Board fids, not panel fids) 3- Use fids, check mount again. 4- If OK, then teach Block Repeat. This alwas

N2 is a reflow process widener so to speak, for leaded reflow less of a impact, for LF more impact, and if using finer LF solder pastes T4,T5 and smaller paste deposits generally, it helps widen window for flux in paste in oxide protection during soa
