The easiest way to solder multi pin connector?


 

Hello,
I am going to move 2 connectors from A row to B row as shown in the picture. 1 connector has 3 pins, the other has 4 pins.


The B row already has some lead there (no pin or connectors attached).

Could anyone help with my questions:
- what is a good and clean way to desolder pins (7 pins in total) in A row. I know that desoldering braid and flux can help. Is there a better way?
- after this desoldering, how should I solder 2 connectors (1 connector has 3 pins, the other has 4 pins) to row B using the existing lead on the PCB?

Thank you.

@russ69 ,

I’d second that. There’s nothing like practice when it comes to soldering.

Cleanliness is crucial. Otherwise the solder doesn’t stick well.

I used isopropyl alcohol when replacing the 3.5mm jack on my Sennheiser headphones.

Here's the first one of a nice video series on YouTube I found both helpful and informative.
