Desoldering problems

[gonzo4886]

Hello, I'm trying to recap my Kenwood KA-9100. This is the first time I've ever desoldered on anything this old. The soldering field came delaminated from the board. I'm afraid I may have ruined it. I had the heat on the lowest setting on my desoldering iron. I'll attach some pictures. Am I able to save this?

Thanks

Direct wiring after you have established that you have broken the trace/pad/connection.

Simple to save.
All that light green around each solder pad is masked conductor. You can solder in the new parts and if they don't make a connection, clean some of the mask off and solder to that cleaned space using wire or whatever to connect the device.

What the guys said above, plus this: I've learned the hard way that sometimes having an iron that it too cool causes more damage like this than a hotter iron. Reason being, but the time the colder iron gets the solder hot enough to melt, the heat has had time to spread and loosen the adhesive that holds the foil to the substrate. A hotter iron heats the solder and melts it before the heat can saturate the area.

yeah, too cold is worse than too hot. The longer you are on the pad, the more chance it has of coming off. Ideally you want the solder to melt almost immediately so you can get in and out within a second or so.

and +1 on scrape and bridge the connection. I've made "lollipops" out of cut-off component lead for this sort of thing.

Agree with all the above. It can also be helpful to add fresh solder before attempting desoldering.
