Re: [HamBrewers] Homebrewing PCBs

 

Here's a few videos on rosin-based solder flux from Dangerous Prototypes:


"DIY solder flux with rosin and alcohol"

"Dangerous Prototypes Flux-Off solder flux test"

"Dangerous Prototypes Flux-Off solder flux test, Part 2"
In the States, most of the solder for electronics is "rosin core"--the wire-like solder is actually a tube full of rosin flux.

Also, in the States "solder paste" is a mix of flux and solder used mostly for surface-mount PCBs and usually silk-screened on to the board and then "reflowed" (melted) after components are placed. Now, I use a flux that is in a "paste" form, but it's not called "solder paste" here. I suppose one could call it "pasty flux," but I wouldn't.

Best,

Todd

A question from the UK, where health and safety laws can
make it difficult to get hold of some materials, what exactly
do you mean by, "Rosin"?
