Lay out all your components first. It is really nice if you have a tray in +which you can put your most used components onto so that you can just pick them +out directly instead of going all the way to the reel or a bag. + + + +2. Pull out your stencil. It makes it really easy to put the solder paste on there. +Clean a surface and put your board(in my case a 2x2 array of the board which come together +to make multiple at a time) right on top. Line up the holes of the stencil with the +soldering pads on the board. I found that using any large pads on opposite ends of the board +were really useful for most of the aligning. Afterwards, grab a sizeable amount of solder paste +and put it onto the stencil. If it was refrigerated, wait for it to heat up a little, as +you want the paste to be easily moldable so it goes into holes easier. Then simply +squeege the paste onto the holes from one side to the other while holding +down the stencil so it doesn't move. Push down hard as you squeege +so all the paste goes in. Take off your stencil and checkout your work under a microscope +to see if the paste aligns with the pads well enough! + + + +3. # Sources: -- GitLab
