1. Back in the early days of consumer digital cell phones, we ran into the same problem. PCB with 2000 parts in a 5"x2" area, and double sided. We ended up using our standard vacuum tooling for the NIC side and stiff ESD safe foam for the NAC side

Hi Liza - polystirene monolayer (blend ?) could be sealed at less presure, ie 35-40 PSI. Temprature could be 165�-170�C. For sure after sealed you shoud make sure the sealing strength (peel strength)should meet min 15-25 N.(bet avg from 25 to 45 N)

Ashok: Haven't unloaded that ESD Coordinator job yet have you? Smocks: Don't work, they're hot, and no one likes them, but they put up with them (sort of). Now if they knew they didn't work, all the customer PR in the world wouldn't help. The bi

Well...maybe. First you would have to determine what type of trays you have. Conductive, dissipative or non conductive(non static generating). Dissipative would be your best choice. In the charged body model, the sudden discharge through a conduct

Bright ideas??? Bright ideas!!! I got bright ideas. In order of decreasing luminosity: * Stop installing the socket, solder the PLCC to the board, dip the board. The socket is a waste of time and money. You never replace the PLCC in the field, a

Joe: Hey, just hose everyone down with water when your humidity starts to decrease to below 40%. ;-) Actually, that�s how some humidity controllers work, when added to your heating system. Well basically that�s how they work. I�m not tryin� to

I promised never to do this - BUT only for you needy folks when I have nothing else to do. And Dave's basically a good person though not as needy as most really needing this stuff. 1) Ensure internal Gerber data really matches board and stencil (Ger

| We only do rework with SMT components or a small amount of SMT work. We are having a hard time keeping the components safe throughout the handling process of removing one or two components, and issuing them to an operator for processing or inspect

Ok so.... I have a boss who thinks there is nothing wrong with stacking completed boards smt&thru in totes and submitting them to QA like this. I mean piled upon one another in a tote. Now... it has fallen on me to try to explain in a convincing mann
