Allowing the board fabricator to define the board you expect to receive is fine, as long as they do a good job. Regardless of the existence of a clear product definition or not, it�s reasonable for you to argue that your receipts must meet the requi

I am still learning the CSM84, but have gotten one board programmed and working. Now, I'm doing the next board, and need to use the mechanical alignment unit for a 22 x 22 mm TQFP. This chip is too large to clear the jaws on any head. Can the CSM h

Wave set-up DOE * Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering. * Contact length the greatest impact. * Control flux density, time through preheaters, top side temperature as the board reaches

Get-out the razor blades, bud. You could run that sukka for 6 sec dwell, cook breakfast on it, and you still will not get fill. [Hole file that is, breakfast will go along ways if peckish, though.] You could fire-up the depleted ozone rework gun [
