Before you start assembly, check the board for etching faults. Look for any shorts between tracks, or open circuits due to over etching. Take this opportunity to sand the edges of the board if needed, removing any splinters or rough edges. (With the boards supplied by me, the edges are already milled, and etching faults are very rare.)

* If you can't find suitable relays, you aren't looking. Brands include Alcatel, NAIS, Aromat, PED and no doubt there are many more. The footprint is an industry standard that has been used for many years.

* PCB is 2" x 6" with four 3mm mounting holes 0.15" in from the edges.
