What is the easiest way to unsolder the 9 pin edge connectors? I am replacing them with new .156 Trifurcon connectors, and I find that removing them while all pins are still attached to the plastic is a pain.

I would love to (easily) remove the plastic before removing the pins individually, but I have not found a good way to do that.

Any ideas?

Thanks.

Quoted from zacaj:

I just use a hand pump solder sucker. Usually I can suck the solder from each pin, and then just wiggle the header a bit and pull it away in one piece

Yup - me too. However, I often have 3-5 pins stuck at the same time, so I have to heat them quickly just enough so that they all break loose at the same time, I am trying to avoid pulling a grommet from the board (which has happened to me in the past.

In regards to a picture, please see below: basically all the connectors around the MPU and Driver boards (I have a Williams System 7 from a Black Knight).

Quoted from BorgDog:

hakko fr-300 or whatever current model is. around $300 usually but if you do a lot of board work/desoldering totally worth it.[quoted image]

Thanks everyone. Pulled the trigger and got the latest model (FR-301).
