15 May 2011 - Update
I have successfully reflow soldered a test PCB. I got the PID routine tuned a bit and was itching to test out the reflow controller. So, I applied some solder paster to a old relay controller board I developed and successfully soldered some components to the board.
Below are some pictures of solder paste and components applied to the PCB.
Here are some pictures of the completed process.
Here are some pictures of a relay board added to the reflow controller case. I’m using the relay board to manually control some outputs such as the oven fan. The relay board contains a four channel optoisolater and can handle 10 amps per relay.
That’s all for now. I still have a few tidbits to tiddy up. I need to wire the oven fan so that it can be controlled separately from the heater elements. I intend to keep the fan running constantly during a reflow process. This will help keep the heat distributed and aid during the cool down process. \0/
Very tidy project, I’m impressed.
