Hey everybody! I was asked about any problems that would be associated with having a plastic casing injection molded around an assembled PCB. I am not sure if injection molded plastic has to be hot, I am assuming so (can they use epoxies?). If they use hot plastic, I beleive there would be an issue with the speed at which the parts would be heated. Wouldn't they be heated faster than the max recommended ramp rate (4 deg/sec)? There might also be issues with the different CTEs of board and parts. Can you pre-heat assembled PCBs before the casing is applied? Are there any other issues? Is anybody doing this? I am sure I will need to supply more info, just let me know what it is. Thanks, gang!
