Hi I do not work for a board house but a manufacturing facility where we do a considerable amount of soldering wires to through holes. We pretin our through holes on both sides of the PCB prior to reflowing the solder and installing the conductor (w

Using common wire size and through hole diameter, we'd expect that the wave solder process would completely fill the through hole and that you wouldn't need to get involved in providing stencil openings, pasting the through hole or reflowing the jump

IPC-2222 - Sectional Design Standard For Printed Board For Organic Printed Boards, Table 9-3 � Plated Through Hole Diameter To Lead Diameter Relationships will give you the standard information you require.

I currently have a board that has several wires that need to be soldered into it. Many years ago I remember wave soldering power supply boards that also had many wires. In order to keep the wire insulation out of the solder fillet and keep the wires

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

I worked with a customer about 2 years ago on a process similar using ProFlow head to put paste in holes for through hole... Similar to Pin in Paste. Somewhat successful; but ran into heat related damage issue from TH components through reflow.

most of thru-hole components can not handle the heat through the oven. they will be burn.

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

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

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
