AW reflow 3

awreflow3 is a reflow oven for soldering PCBs based on Andy's Workshop awreflow2. Technically, this repository contains the missing electric diagram and a layout for the oven, with some modifications in order to suit the parts I had lying around. The purpose of this repository is that you can also pull the files and modify them according to your needs.

Prerequisites

This project has been developed with KiCad

Notes

If you have to order the MOC3020 from the schematic you could get a MOC3023 instead and do away with the Q2 transistor and adjoining resistors.

Other things worth mentioning on the actual oven. Get one based on halogen heating elements just like Andy has done. Mine is a quartz elements oven and the PID is totally useless due to its very high inertia. I had to bypass the PID and hardcode some time intervals where power level is 0% and others where power is driven at 100%. At 1000W power and and 9L volume my oven can still bake a full tray of leaded solder PCBs, only a bit slower than others. Here is how it looks:

NOTE I currently have 9 extra PCBs already made. If you would like one drop me a message here and I'll deliver it for $3.44 + shipping + Paypal taxes
