This is a page to keep helpful documents and hints for building your own Hermes board. Bare circuit boards are available from link TAPR and after they run out, from Apache Labs. The bill of materials and schematics are available from Apache Labs.

• Bill of Materials
  • Bill of Materials with columns for the back side and front side components
  • Terry, N8AB has sorted things out a little differently, which can be helpful sometimes.

• Solder Stencil Gerbers
  • Back
  • Front
• Back Side
  • Back Side Component Placement Diagram which has like components color coded so you can place them all at once, and then go on to place the next component type.

• Front Side
  • Front Side Component Placement Diagram (thanks to Terry, N8AB) which has like components color coded so you can place them all at once, and then go on to place the next component type.

• K9IVB Hermes Page has some good build and VNA info.

• KL7NA Specific Build Notes

The basic method follows this video. I used the solder stencil to put on the solder paste. Then the surface mount components were placed. Then the board was baked in a reflow oven. This was repeated for the top. Surface tension holds the bottom parts on when you reflow the top. Then the solder bridges were removed with a very fine solder wick and a good soldering iron. Then the through hole parts were soldered in.
