Hi Technetters, Does anyone have experience with cocuring conductive and nonconductive epoxies? We're looking at a process of dispensing nonconductive epoxy to secure the middle of a cap, then dispensing conductive epoxy for the terminations, placing the component, and then doing only one cure? The two epoxies will most likely come into contact with each during the dispense or cure step. We're trying to accomplish two things; additional strength of the attachment and a dam for the conductive epoxy. For risks, we see a potential for the nonconductive epoxy developing a barrier between the cap and the substrate. There's also an issue with thermal expansion that I need to do the math on. But, this should be pretty straight forward. Any stories out there? Success or failure? Thanks in advance for any input. Glenn Pelkey Quality/Reliability Engineer Maxtek Components Corp.
