Hi I am in favor of the best money can buy tiles, and everything including an ESD officier and training for everyone. Long term less money is spent and ESD protection is kept high continually. Boy do I have stories like the cleaning guys who put on

Enrique It's true that higher energy guns do a better job measuring "light" materials. [Actually, if that was true by itself, you'd expect the fabricator's readings to be higher than yours. But, HEY!!!] Regardless, there's alot more to getting an

My two Process Engineers are at odds with each other. One says that the Tact Time is only the actual Pick-n-Place time to build a board, and the other says it needs to include the load/unload time as well as the Fiducial reading time. Example: So

You're entirely correct. The gold is most likely gone away. [Don't forget you can check if the surface is still solderable with a hand soldering iron.] We're not sure it it will give you the results you seek, but consider using a dye penetrant fai

Dave, thanks for the info. This sounds like it would verify the presence of an open. We have verified that these balls are open and I am trying to figure out if we are fracturing or not wetting. causing these opens. I would use the die method on ne
