Radio cleaning and pre-emptive cap. repair?

One thing that helps (me at least) with any rework is the ABILITY TO ADD MORE FLUX. There are lots of fluxes available, you want one meant for electronics, and Kester is / was the "go to" people. Unfortunately many big suppliers, such as Kester, only offer such things as flux pens--which are OK as far as they go, and then gallon or 5 gallon production sized.

Another thing to keep in mind is that there is a VAST difference in PC boards. Years ago when I worked for the Motorola shop, we built a large repeated system..........using multiple receivers on one freq at different locations, then the audio outputs are sent to a device called a "voter" which decides which receiver audio to send to the transmitter for repeat

ANYway, some of the receiver strips needed repair and modifications. They were TERRIBLE quality cheap grade PC boards, and attempting to remove components resulted in the LIFTING OF A PAD.

You want a large enough/ hot enough iron to heat the work up quickly without sitting there for a long period, and transferring heat through the work area, causing damage.
