When it comes to how much epoxy [aka. "glue"] to dispense to hold a IC or any part with significant mass, on the bottom of a board for wave soldering, is more better? The way I see it, one good dot should be holding such a part on the PCB. If not, th

Continuing the line of Michael's, the previous poster, comments ... The more Krispy Kremes, the better. Yeth!!! The more beer, the better. Yeth!!! The more epoxy, the better. Uh, I don think so!!! We look at this from a papa bear, mama bear, bab

| I recently had the opportunity to visit the vendor who is making my boards. On my trip I noticed that the guy who was in charge of the SMD placement machine (brand new Samsung) still had to manuallly place about 20%-40% of the parts after placement

Hello colleagues, Question. Who ever done 4 mil (100uM) electro conductive epoxy dispensing? is it even possible? I did 6 mil but very unstable results... Now I need 4 mil for an application.

Thanks, we'll try this too. We aquired an asymtek millenium for dispensing selectively. It is setup for epoxies with a needle dispense head so we'll try to make it all work for us. One-part silicones seem to be the popular solution.

We're looking to add conformal coating to some of our pcb's which range from 2x2" to around 6x6". I would like to use a coating material that is not nasty smelling requiring ventilation or filtration if possible. Are there conformal materials that ar

Thanks for the tip. I'm still getting familiar with the machine by reading the manuals as I have time. Was wondering what type of solvent you use to clean the dispensing mechanism parts? Or do you not clean anything and simply dispose of the syring p
