+dhe Posted November 27, 2021 Share Posted November 27, 2021 This Horizon is kind of interesting. It actually has a number of holes, that are used as through holes for wiring. Question #1: Does anyone know who Jarvis Hill is? Question #2: What's my best bet for cleaning up the nasty solder flux all over the board? It's nice the serial number scheme went up to 999,999 Quote Link to comment Share on other sites More sharing options...
RickyDean Posted September 25, 2023 Share Posted September 25, 2023 (edited) Don't know if you ever solved the Flux problem here Dan, but I use Automotive carburetor spray then clean with warm soapy water and rinse again with a bit of 90% alcohol with great results. Then I use a fan to dry it, and then let it set a couple of days to be sure any water residue is dried off. That or let it set in the warm Georgia sun for a bit. FYI.
