Dback, Current method is by using dispenser machine to dispense the glue at PCB. This non-wetting is randomly and not repeating to the same location. My adhesive height is 0.01" to 0.035". Is this will cause the component to had a gap between the t

Shy, You mentioned that you are using "dog bone" apertures for your chip components? It doesn't make sense to me. I thought that the "dog bone" was used for fine pitch devices, to keep the solder away from the center and avoid bridging. It doesn't

Q: I thought you said that the parts that weren't wetting in reflow were the parts with epoxy. A: Yes you're correct. Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in ref

Q1: How many mils the gap between the terminal and pad? A1: It depends on properties of the glue and z-force when the component is placed by the assembler. Q2: Your practice is for technology SMT-4? A2: We don't understand SMT4. We know that very sm

Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? A: Yes, but somebody here don't agree with me that the glued part need help from wave to get the good wetting. They are wrong

You are probably right about the oven fumes, but there are indeed magnets in the bottoms of some of the feeders.

Motorola had there own Verification system, which required magnets to be installed in the bottom of each feeder.

Does anyone know why there would be magnets on the bottom of the locating plate on a CP6 feeder ? We seem to have some feeders with them and some without.

For the criminally insane to help them locate the feeders? Or to help hold them down when changing them if you don't have those huge lumps of steel they clip into?

Dude - Keep away from the oven, you have sniffed to many fumes. Magnets aren't listed in the parts list, sacrafice an operator until someone fesses up!!!
