Today we take a look at an inexpensive pick ‘n’ place machine found on the Chinese auction site Taobao for 22800RMB (about $3,600). A pick and place is a machine that puts electronic components onto a circuit board that has been coated with solder paste. To complete the prototype you just place the populated PCB into a reflow oven. We hope it will speed up production of one-offs and single prototypes.
The NeoDen TM220A is a table top pick and place designed and manufactured in China. Most PnPs are huge machines that take up a room, but this fits nicely in the workshop. It doesn’t require a separate compressor, it has a noisy internal vacuum pump that provides suction for lifting parts.
Up to 15 reels of components can be loaded. 12 x 8mm, 2 x 12mm, and 1 x 16mm. A tray at the front holds larger components like chips. The bigger TM240A that has twice as many reels and costs $1000 more. For us the TM220A is the ideal size. More importantly, it’s light enough to carry up two flights of steep stairs into the workshop.
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.
