3D printers offer possibilities while assembling

You only need one drop of solder on the back to stabilize 1 pin.

Remove the support, solder the 2nd pin then go back and finish pin 1.

PLA has low -ish melting point. I just received some ABS, PETG and TPU for testing.

Every pcb has 5 of these and is not easy to do that. It is for a (small) production and takes time to deal with such nonsenses.

Besides, my wife is going to solder that boards, so I have to come up with an easy to use method. Usually pcbs are assembled on a device like this but the sponge that presses those pins, pushes them sideways.

I'm not sure I understand. Is that device used to dip the assembled PCB in a solder bath?

Or is it used to hold everything in place, then you flip and solder the bottom side?


I've been thinking about the heat applied to a lug like the one you're installing. I don't think the heat would transfer to an alignment tool that much, especially while soldering the first pin.

I'd solder them all only 1 pin, remove the tools, then solder the 2nd pins.

This orange device is for placing all through hole components, press with the sponge cover, flip on the other side and solder by hand.

This is not for a bath soldering, although you can place components then slide the pcb through a solder bath. Have not done that.

For SMDs either I order from JLCPCB the pcb with the SMD components (when low quantity is required) or for more mass production I order only the pcb then have locally a company with pick and place machines for assembly of the SMD part. The rest is done inhouse.

One idea for the faston parts would be to make holes smaller, though this come too tight to fit properly. It is risky.

Do you have a part number or link to that tab thingy?

EDIT: There's 4,975 models at Digikey. I'm looking for the exact specs of what you're using (height width, thickness).
