Surface mount soldering equipment was gathered to attach the IO expanding ICs to the ModuKey boards. Surface mount resistors had already been attached. The resistors were connected with wire solder and a soldering iron, but for the ICs, it would be easier to use proper solder paste.
Most of the soldering went well, but in a couple of places there were solder bridges and places where the chip drifted while the solder was fluid. The bridges were cleared with a fine-tip soldering iron and the maligned chips were corrected by reflowing the solder and position it correctly.
Eight chips were attached to eight boards. The 4x4 boards each had sixteen switches and the chips were capable of sixteen switches so all spots were taken. The smaller boards each had and IC capable of eight switches but they only had space for four. The outputs were broken out to standard header pins so some of the switches will be mounted on other boards with no ICs.
