This PCB Solders Itself, Then Others

Posted on

There are occasions when even the greatest soldering irons will not velocity up your soldering tempo. So what if the board soldered itself? That is the purpose of Carl Bugeja and this PCB that may solder itself after which different boards!

Bugeja’s strategy is described utilizing a pizza analogy: The PCB is the dough, the solder paste is the sauce, and the toppings are the circuit elements. Put all of this into the oven and you’ve got a  ̶t̶a̶s̶t̶y̶ ̶p̶i̶z̶z̶a̶  a PCB able to go!

For these not acquainted with floor mount electronics, massive stencils are positioned over pre-fabricated PCBs. By way of the stencils, a layer of solder paste (suppose toothpaste, not typical solder), is utilized. A pick-and-place machine is then used to drop the elements onto the solder paste, after which the entire board goes right into a reflow over the place the elements are baked into place. If it’s good to make hundreds of boards, then that is the way in which.
