Well I have some of the yellow paper ordered. I note the pulsar paper is backed by thicker stock, perhaps to even out the heating. I could always add a sheet of copy paper during the lamination process. I'll do some testing when I get it as I have a modded laminator with good control.
To tin the etched PCB I remove the foil & toner coating with a light sanding and an acetone wipe. As an alternative to tinning, using pure petroleum jelly as a wipe keeps the board from oxidizing for several days and solders well! I apply that before I apply the paste because the cohesiveness of the p.jelly helps bind the solder paste to the PCB during the stencil application. The p.jelly also stabilizes the plastic transparent stencil when registering it with the copper pads before taping down.
In combination with my reusable laminate plastic (3mil) laser cut stencils applying paste in a couple of minutes I was able to pick and place all smd parts and hot air solder the PCB in 15 mins.
