I spread some water-clean flux on the board, put solder on all the pads and drop the 0603 resistors on. Not only could I do that PCB faster, after I wash it it looks like a machine did it. </span><br style="font-family: Monaco;" class=""><br style="font-family: Monaco;" class=""><span style="font-family: Monaco;" class="">I’m with Roman, I think building a big through hole board belongs in one of the circles of hell. All that flipping over and having parts fall out, clipping leads, burning my fingers as I try to get the parts tight to the board, etc. Plus…. I hope to never do panel wiring again as long as I live. (I still have some original Buchla left overs to complete) Even my passion projects I build by hand with SMD and I have a pick n place machine! I do not get any TV watching in during the assembly, I listen to CNN in the background, does that count for anything?</span><br style="font-family: Monaco;" class=""><br style="font-family: Monaco;" class=""><span style="font-family: Monaco;" class="">Incidentally, I got the feeders for my desktop from that thread a few months ago. Since I was ordering them from China, I paid for 4 but they only sent me 1. It is perfect for what I need, but I won’t be doing any more business with them after they took my money and only delivered 25% of the order. I was impressed by the rig Roman offered, but I don’t know where I would put it. My desk is WAY too cluttered for such a thing. </span><br style="font-family: Monaco;" class=""><br style="font-family: Monaco;" class=""><br style="font-family: Monaco;" class=""><span style="font-family: Monaco;" class="">Mark</span><br style="font-family: Monaco;" class=""><br style="font-family: Monaco;" class=""><div><br class=""></div><div><br class=""></div><div><br class=""><blockquote type="cite" class=""><div class="">On May 17, 2022, at 11:11 AM, Roman Sowa <<a href="mailto:modular@go2.pl" class="">modular@go2.pl</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">OK, challenge accepted!<br class=""><br class="">Partly because it's fun, partly because thought I can beat it and partly because David is nice guy, I took the challenge and tried to beat David's markup doing it in SMD, obviously without P&P.<br class="">So for me it was 72 resistors of the same value, 0603 case.
