I'm new in SMT and the company I'm working with has already purchased SMFL-3000 manual pick & place system with hot air and we don't have reflow oven. We are now starting design SMT board. My question is, how we reflow the solder? After all component

Hello everyone, Talking to my boss today I was able to determine what we're really looking for in terms of reflow soldering. The company is not looking to do a volume run; we're trying to solder chips for prototype boards, which are currently done w

Here is what I would do faced with your problem. First I would profile a similar board or use an existing profile. From there I would place the dummy device on the surface of a sample board with a thin thermocouple soldered to the board surface under
