Hi, I would like to have information about means to improve the stability of a SMD-Line: indeed the variation of the daily performance is too important (between 50 and 250 ppm). What is the solution to reduce these variations? climatisation, other re

Ken, With all due respect, you need to quit preying on these new guys. I mean cummon man........

Actually it is the number of defects which varies!!

It is a FUJI Line with the machines: GP641 GL641 CP6 IP3 the oven is the smt Quatro peak. Moreover we have an AOI.

Hey Ken...my car won't start. Can your feeder racks or storage totes solve that problem as well? Sheesh....

Hi mates, finally! some sense to all this, so this bloke is concerned about "ppm = quality" variations... looking back through all the muck in this thread, last posting before the s**t hit the ceiling was: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Date: June

Most SMT lines are comprised of several pieces of equipment. Each piece of equipment, the components, the plant environment, and the people running the line can have / cause variations in their operation that each can affect product quality. Consid
