0816 Automatic Feeder

0816 Automatic Feeder are used in a Pick and Place Machine to supply parts for assembly on a PCB. It's designed to integrate well with the OpenPnP pick and place software.

Current Status (2017-12-30)
  • firmware updated for enhanced reliability
  • released printed parts v1.7 (see changelog)
  • design/firmware are considered to be final, not much changes to be expected any more.
  • 8mm feeder are tested and work well.
  • 12mm feeder are printed but not yet tested.
  • 16mm feeder were never print nor tested. if anyone does I would appreciate feedback.
  • designed and highly optimized for 3d printing
  • feeder supports embossed plastic tapes and paper tapes
  • feed lengths: multiples of 2mm, so 0402 packages are supported
  • unit for automatic cover tape-removal
  • 3 sets for 8, 12 and 16mm wide tapes, (should work with tapes specified e.g. by vishay)
  • the feeders lane height (1.25mm nominal) is adjustable for different types of tape. Tested are
    • thin paper tapes (thickness 0.6mm, e.g. most 0603 resistors)
    • thick paper tapes (thickness 1.0mm, e.g. 0603 caps)
    • embossed plastic tapes (thickness 0.3mm, e.g. 0805 caps) (experimental)
  • costs about 10$ per feeder (sourced global) (1.2$ plastics, 3.00$ N20 motor, 2.00$ SG90 servo, 0.8$ motor pcb plus some screws, microswitch, bearing, springs, cables)
  • one 8mm-feeder prints in about 4 hours (@ 0.3mm layer / 0.4mm nozzle / ~70mm/s)
  • trigger manual feed operation via pressing on cover tape tensioner. Useful to setup feeder.
  • overall width of one feeder at 8mm tape → 13.5mm, 12mm tape → 16mm, 16 → 20mm
  • compact feeder pcb for clean and easy cabling, order directly from OSHpark for less than 2$ per 3 pcb
  • native arduino mega shield for up to 24 feeders including checking feeder state plus some extra ADC in and power outputs
  • alternative shield arduino mega sensor shield 2.0 for up to 48 feeders without extras
  • arduino firmware to interpret G-Codes received from OpenPnP to trigger a feed and configure feeder
  • license: Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)
  • provided as is, no warranties


Feeding 0603 paper tape several times while looking with the downcam to the pick location.
Feeding 0805 plastic tape several times while looking with the downcam to the pick location.
Feeding 0603 caps in 1mm thick paper tape several times while looking with the downcam to the pick location.
And even see when it doesn't work (native shield only): Some rudimentary check is performed on the state of the microswitch within the feeder. If something went wrong, the error is reported to OpenPnP.
