Details on removing the potentiometer and soldering the wire #3

Open Tomasonx opened 2 years ago

Tomasonx commented 2 years ago

I have already tried on 3 pieces of DRV8825.

Can you detail the process and possibly check if the soldering was correct?

@Tomasonx, Hello, what is the problem exactly? just use a soldering iron, use flux and solder and remove the potentiometer. Or you can use a fan if you have a soldering station... personally I just removed it with a soldering iron. Just fill that potentiometer with melted solder (all 3 contacts) and then just move it away from the board. Hope it helps :) After it is done solder the wire like on the picture image

everything according to the circuit image

  1. Removing the potentiometer = no problem.
  2. After that you have 3 points, VCC, GND, Output. From the picture I understand that you are soldering only with point 3 (Output), right? Because it's a very small point, how do you test (measure) that you're soldering ok?

@Tomasonx, yes only point 3 (Output). You can use a magnifying glass to check visually. You can use a multimeter to check if you don't have a short circuit between VCC, GND, and Output. If you want to check more you can follow that PCB trace (it is probably going to IC), you can test if it has good contact.
