I have a question regarding post cured property of SMT adhesive. If after component placement, the epoxy dot gets compressed and bridges between the 2 pads, what would the impact on the circuitry? Would it pose risk for flux entrapment? Could the cu

I need to build a couple of prototype SMT boards and need some recomendations on some adhesive or epoxy to use to hold the parts down prior to hot air soldering. I find that some parts want to skip across the board when heated, or they want to walk

We have a new assembly with bottom side components, and all the chip caps and resistors are 0603s. The dog boned shape of the caps necessitates a pretty big (and tall) dot to hold them still during placement, and when they get placed the dot squishe

I would bet that it is a SMT adhesive used to ensure that the BGA does not move during a secoindary reflow prcess. this glue is easily removed with a soldering iron. Russ

Could anyone please give me some insight on the time/temperature requirements for curing SMT adhesive used for a high temperature (96/4 solder) application in a bake oven, rather than using reflow? I understand that it would probably vary from epoxy
