Can sombody help me with this?? When applying solder paste, what factors determine how high off the PCB the stencil is? We use no fine pitch devices. (mostly 603 and 1206 size components) Any help would be greatly appreciated. As you could probably g

Hello all, Are BGA's easy to develope shorts? If a process is stable and all of a sudden you get BGA's shorting out on you, what might be problems? We've checked our solder paste amount, and we've rechecked our reflow profiles and nothing has chan

I'd like to find some technical papers on the reliability of reworked BGAs. If you know of any, please let me know. I have a concern about this because our current rework process does not apply solder paste to the pads prior to placing the part; th

Does anybody out there have any special insights into utilizing no clean paste in high frequency RF applications? I would imagine there may be some issues with solder balls that would affect functional test (Earl, do you have something for me here?)

For Sale, two CAM/ALOT 1824 glue dispensers. These machines are in decent shape, but need the interface boards and the pump if they're to be used for SMT glue. They are the same as a Model 1818 now that they have been refurbished. One was refurb

In addition, consider: Solder paste selection, including clean or no-clean is also quite important. This can vary from application and is somewhat process dependant (what works best in the environment). Relow profile. A must for many reasons. And

Dave - will placing MELF's in SMT eliminate the original problem? Is the flux aggressive enough to clean mold release agents from the component manufacturer? Good point about LT reliability, just wondering what would happen if glue was eliminated fr
