recapping my controller took a fair bit longer than expected due to very tricky angles on the cap leads, but job done. gone from late-2000s era aluminium electrolytics to modern alupoly across the board.

board went through the ultrasonic bath, got a spray down with isopropanol, the connectors got flushed with contact cleaner, and then dried over the IR preheater. manual inspection came out great. all rails tested and... it works!

gonna do the rail noise measurements in a bit. food comes first ^^

also, if they're still wonky further downstream, I have a bunch of MLCCs and leaded alupoly caps to solve that.

@dysfun through-hole legs, not the metal (although I'm not a pure RoHS lab here anyway; I keep SnPb around)

@gsuberland @dysfun what do you use the SnPb for?
-
Graham Sutherland / Polynomialreplied to fuzzySynths last edited by
@fuzzySynths @dysfun when commercially manufactured boards come with a high temperature solder and I need to rework them, it's basically impossible unless I alloy the existing joints with a lower temperature solder, and SnPb is great for that. it's similarly useful for making large joint rework easier.

-
@erincandescent @gsuberland @dysfun how can you tell if it's SnPb?
-
@fuzzySynths @erincandescent @gsuberland it'll be missing the RoHS marking.
-
@dysfun @fuzzySynths @gsuberland also last time it was relevant to me the device was manufactured in 1990
-
@dysfun @fuzzySynths @gsuberland also the solder had the telltale shininess of SnPb and orangey-brown rosin flux residue
