Does the temp. profiles used to reflow double sided pcb's through a IR oven on FR4 board material have to be re-established if it is changed to polyimide? Boards will be baked out prior to assembly. any response would be most appreciated.

Hi, I have been assigned to purchase a SMT assembly line for electronic ballasts used in compact energy saving lamps. I have the circuit and list of components, but know nothing about SMT. Could anybody tell me where to start and what to look for.

What is the right way to count the opportunities for defects in order to calculate the quality (in ppm) of SMT assembly processes as well as the quality of the PCB's? Please replay to: fogel_m@netvision.net.il or micha.fogel@ecitele.com

Check out some of the brokers on the internet. Look under "Used PCB Assembly Equipment". "Fastex" is one of the companies that sells used equip. There are quite a few. Make sure you get a warranty with whoever you pick...
