How the stencil machine applies solder paste to PCBs #ManufacturingMonday (video)
This is how we get solder onto our circuit boards at Adafruit! The solder starts as a gray paste with a soft-serve-like consistency, which is then forced through a stencil onto the bare PCB below.
The stencil machine is capable of high precision and excellent reliability, allowing us to be certain that each circuit board has good solder paste coverage before heading into the pick ‘n place machines to be loaded up with components.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
