QMX+ build ... don't do what I just did


 

I've starting on installing all the toroids in the low pass filter section
of the QMX+.
?
I noticed after I had soldered in the first one (L519) but fortunately before
I clipped off the leads that I had inserted one end of the toroid into the hole
with the text "LPF" next to it, not in the hole at the end of the graphic
of the toroid on the PCB.? Whoops!? Well, it was easy enough to unsolder
the lead and re-insert into the correct hole.
?
So, all is well, I hope.? The LPF hole still has solder in it.? Is that OK or
do I need to clean out the hole?
?
Thanks, all -

Bruce,
?
I'm just a little behind you on my build, I just soldered L502 in. As far as I can see, those LPF holes don't have anything soldered to them, so you are all right.

I would use braid and a bit of extra flux.? I just did this on? some low pass boards for a U3S.? I did add a bit of solder to the holes so the braid had good contact.? On one board I managed to reverse the c1/c4 with c2/c3.? I was able to remove the capacitors using ChipQuick low melt solder, then filled the holes with 60/40 ( don't leave ChipQuik on a board as it is brittle) then cleaned them out with braid.?
