This DIY pick and place machine assembles small SMD parts like resistors and capacitors on electronic circuits. It is built form a flat bed scanner, from a printer carriage and from a CD drive. The three axes controlled through a Ramps 1.2 electronic<\/a> from the amazing RepRap project. The gcode to control the movement is compiled through a C-script form the part list generated by the PCB design software (eagle). The machine can be controlled through a 3d printer host software like Printrun.<\/a><\/p>\n

The plate for placing the PCBs as well as some support parts for the carrier are laser cut on measure from acrylic. The parts are presented to the machine through exchangable part carriers that snap on my magnets. The arts are positioned on the carrier through pins that reach into the holes of the SMD-tape carrier.<\/p>\n

See this video<\/a> showing the whole process of assmebling boards with the machine.<\/p>\n
