Reflow Oven

I started to create a number of circuit boards with surface mounted components.  Though I had a CSI 825A SMD rework station, soldering micro-miniature components was starting to take up too much time.  So, I researched solder reflow ovens and found one by www.whizoo.com that looked like it would work and cost me about $200-$250 with my modifications.  The following is a photo montage of the end of the build.  WARNING:  If you try this at home wear leather gloves when disassembling or handling the disassembled oven or there WILL BE BLOOD!!!...and yes there was!!!!!

I reused the existing holes and tapped them for an m4 screw.  I laser cut the discs from silver acrylic.

I used a Nickel Plated Nibbling Tool (1) and some jeweler's files with a light 220 grit sanding in one direction for the brushed look.

The connector is a kit (Mini Connector + Panel Jack Mount).  What a deal!!!
