Hi For around $10, you likely can get a stencil with your board order. Screening solder on the board can be set up with masking tape and a few scrap boards as “stops”. With the solder paste already in the correct locations, there is a lot less need for messing around. The board can be reflowed with a toaster oven…
No, none of that is anything I came up with myself. One of the guys at work was into doing it this way. He ran me through the whole thing. Much easier than the alternatives.
