Default Re: Yaesu FRG7700 shields cleanup

There used to be a tinning liquid available for tinning pcbs, so that the all the bare copper tracks became tinned. I wonder if it would work on your screening covers, although they will need a good cleaning first before being dipped. It looks like something has attacked the tinned plate surface, maybe moisture.
