Craig, Since you didn't share any detail regarding the component side of the board or what other components reside on the bottom side, I'm prepared to take a stab in the dark. Have you considered doing a double sided reflow on this board? Also

John, I totally agree with you on all your above comments. You obviously have a real grasp of your subject, and are very knowledgeable. My colleague and I would like to take this opportunity to request information on personnel ' training' aspects re

SMTRESEARCH.COM OR WPSALES are also options. There are lots of them out there who will supply just the discs, new nozzles, or do retips on your nozzles (cheaper) and all I've dealt with are cheaper than Fuji. As Kevin says your disc's need to be cons

We use our ISO-14000 registrar the same as we use our ISO-9000 registrar ... get 'em in, agree that they've found something to write you up on, pay your $50k bribe for another years worth of cert, and get them out of the plant. When they're rippin'

Jax, I agree completely. In fact even if the Tech didn't know exactly what to do he should know HOW to align resources to solve the problem. This may include ordering a replacement manual, attending service / programming classes, calling technical

What's Up Big Man, Although I agree with a few things Dean said, personally I like back-light. But since you probably won't listen to me here's is the suggested info: Lead_check area= 60% Vision type= 120 P_pattern= 34 This rest is part dependant

I agree with Nick. You should check with the manufacturer to determine what type of plating is used on the components and see if the manufacturer has any recomendations on materials that may help. If no exotic materials are used, the culprit is most

Mike: You called it GOOP, and I agree with you. The closeset we came to the daphne was alvania but it is not great stuff either. I am now trying some stuff called PERMALUBE madae by Certified Labs. They assure me that it meets or exceeds fuji specs

Jack - The last time I checked IBM was specifying a minimum of 4800 cubic mils of paste for each pad. This is required for acceptable reliability, not just to make the connection. There is no way you are getting that volume with a 5 mil stencil
