Does this only happen with certain feeders or certain components? We have a few regularly used components that experience the same problem ( Philips SMT machinery ) where the cover tape is just too sticky. Experience taught us which components will c

Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

Funny, I just had this discussion on LinkedIn. Must be the season. It is always acceptable and preferably to profile every assembly, if you have the time, resources, and equipment to do it. That is the only way to get the most accurate information

1st off for the forum folk, I don't like the fact that the new system only let's you see the posting your replying too, I'd rather be able to see the thread..... Anyhoo, why this alloy?, it's because it's the device manufacturers preferred and the c

Kevin, There are a number of custom integrated systems that perform automated insertion of "odd" components. These system use either a robot or cantilevered X,Y,Z Cartesian motion systems. Our systems have accepted standard and custom component feede

How can one go about defining the complexity of a PCB for characterizing reflow profiles A large balanced board may be easier to profile than smaller unbalanced board ? Any ideas how to define an index to calculate the complexity based on size,weig

Hello I'm mounting a notebook board with the memory conector manufactured by CONCRAFT. We are facing some soldability problems with this conector because some ground leads don't solder on the pads. I tried 4 different brand of solder paste, tried to

Jackie's posting recently and responses to it got me to dondering. First, recollecting, we bought an IR rework station a couple million years ago. It had a IR source on a stand, a bunch of lenses, and Reynolds aluminum foil for shielding near-by co
