Thank you for advice, But main concern how to detect the problems with BGA on SMT line, and how I can validate "good" or "bad" profile. PS: SPC said that process Cpk 2, temperature profile in the upper spec limit for TAL and peak temperature.

72 different part numbers, 53 being 8mm, remainder being 12-44mm and 3 tray. It may be low but anymore than 100 and you give up throughput because of feeder locations. And thinking about it, 70-90 is low for a low volume high mix line. I guess if I w

Hello Stefan, Thank you for your reply. I see now that manufacturers are aware that this kind of thought process is necessary for the bottom line profit. It is also true that one can be "seconds wise and minutes foolish" in the process. I read with

Dear sirs, We are experiencing problems with lines of lead formed inside the solder joint. In others words, there is a problem with the formation of the solder joint, after analyses on a microscope we can see the lead grouped in some positions. This

Are you saying that it works in "no fmi" mode, but not in manual? Please tell me how it works in both. I'm asking you to change things to ascertain the problem, not as possible solution... if you can't get the board to stop in the correct position,

A quick question(s) to anyone who operates SMT lines with only one multi purpose flex machine (P&P). What is an ample feeder count for this machine?...and secondly, do you have a standard kit of common parts that you would wish to reside permanantly

Thanks for the response k_h, A few follow up questions... 1. 70-90 slots seems low for a one machine line. What is the maximum number of different parts on your worst case job? 2. Could the common parts be adressed by being assigned as "point of use

"Point of use" could be your common high runner parts. They are sometimes kept next to the machines (at the point of use) and may be categorized seperately from the rest of the inventory. In your case all of your parts are inventoried next to the m
