The cover 'salt' is essential to keep the roller wetted. We tried many
alternative dross absorbing oils and they work ok until you start processing
panels. Why do you want to eliminate the salt?

Subject: [TN] Roller Tinning Process
Dear Technetters
As you know that some PCB manufacturer uses roller tinning soldering
process. In this process firstly flux is spread over PCB and then passed
through rollers to be soldered. In this solder alloy sometimes a bit salt is
added to improve soldering quality and help solder to be appread bright. I
want to learn that if there is any alternative material used in roller
tinning soldering process to elaminate salt or is there any alternative
roller tinning soldering process flow.
Thanks in advance to your comments and knowledge share Best Regards
