When testing a high impedance board (up to 1 G ohm) I found that the SMD 0805 10 Meg ohm resistors measured only 6 meg ohm. The problem was traced back to the liquid flux used with Rohs solder. (100 Meg and 1 G resistors are through hole and measured correctly.) I then wanted to measure the resistance of different =91flux blobs=92. I made big solder blobs on 0805 SMD pads (spacing bet...

I am trying to solder some RG-6 shield to a pcb. The braid won't tin. It's almost like it's dissipating the heat faster than I can apply it. With both a temp-controlled iron (set as high as 700F) and a mondo 100W stick I finally tried. The solder will barely melt when touched to the braid opposite the iron. I've applied some Kester rosin paste flux as well using my trusty Kester 60/4...

Has anyone ever actually been unlucky enough to get solder splattering into their eye? I've had it hit my leg, hand, and face, but never in my eye.

The power wires for a 500 watt ebike motor go through the board. It there any off the shelf insulator designed to protect the caps and other components only 13 mm away? This is asking for a torch. Bret Cahill
