Here our senerio: * There are no funds for additional test equipment. * Have only Delta Scan results, that are very limited. * Failuer of Delta Scan, PCB goes to vendor for X-ray analysis. Do you have a similar process and do you do anything diffe

As well as checking board supports you may want to check your nozzles and make sure there not stuck up in the windmill.

Your objective is to go for a quality process and if you acheive that you don't need AOI! But how do you monitor your process? AOI can do this. Just select a machine that suits your purpose and budget.

thank you, Dave, I replied to Tal's e-mail. I am not aware of any formula used to determine the tolerances. We were collecting data from Topline, Siemens and other component supplier. On small components, the aim was to detect components on the side

We screen print on half of our 15 lines with no problems. We're currently using Ciba 7275, but are looking to change to Loctite 3616 (lower cost).

I would like to know if there are any detailed studies or sources of information regarding the use of round pads vs square pads with chip components (0402 and greater).Thank you.

Why are you unable to place this part with your Machine. Part to big? No pick up point( nozzle landing area )? No Feeder? Vision recognition? If we know why you can't place it, we might have a fix.

It is certainly a process indicator. What is causing this condition? Is it a chip that has its toes over the edge, edging towards tombstoning? Contact: * Jack Crawford [ JackCrawford@IPC.ORG ] * Mel Parrish [ mparrish@SOLDERINGTECH.COM ]
