You may want to pre tin wires then dip into flux before soldering Does work!

I, too, would bend it 90-degrees prior to assembly and I would also put on a little spring loaded, removable, heat sink on to the wire to stop the heat transfer up the wire. After the wire is soldered, then remove the heat sink. Try the one from Ra

I guess I wasn't too specific. We currently use 1,1,1 for spot cleaning and minimal rework of PCBs. If there is a lot of rework on a PCB we will use water soluble flux and wash it. This may turn out to be our only alternative, but I hate washing a

Hi All, We have a board that's going through our process at the moment, it's 1.6mm thick and has 4 wires soldered into it, these are 10SWG multi stranded wires, i'm finding that it's difficult to get the holes filled with solder as it travels up

It's hand solder, the wires are free issued, what i'm finding is that if we keep the heat and push enough solder into the joint that the component side wets there is that much solder moved up the wire that it goes solid. this is no good as the custo

The minimum vertical hole fill is defined as follows: Class 1: Not specified, with a 270-degree circumferential fillet and wetting on the secondary (solder source side) of lead and barrel, and a 75% coverage of the land area on the secondary side. Cl

So, a 10SWG is about an 8AWG. We can't think of a IPC standard for design of this type of product. That the solder is running up the wire indicates something is wrong. We wonder if either: * Holes in the board might be too large for the wire. Doe

I was afraid so. Hand soldering wires in general is not difficult, but with your constraint of the space restriction it does make fairly hard to do. I am assuming you have a 2 sided board and stranded copper wire. So once solder starts to flow, th
