====== 0816 SMT Automatic Feeder Design ======
The 0816 SMT Automatic Feeder are designed to be used in a pick and place machine to supply smd parts for assembly on a PCB. It's specially designed to integrate well with the [[http://www.openpnp.org|OpenPnP]] pick and place software.

===== Features Of the 0816 automatic smt feeder =====
  * 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, easily replaceable by an own solution if preferred
  * 3 sets ready to print for 8mm, 12mm and 16mm wide tapes
  * 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)
  * costs about 10$ per feeder if sourced globally (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 5-7 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, 16mm -> 20mm
  * [[maschine:pickandplace:feeder:0816feeder:feederpcb|compact feeder pcb]] for clean and easy cabling, order directly from OSHpark for less than 2$ per 3 pcb
  * [[maschine:pickandplace:feeder:0816feeder:nativeshield|native arduino mega shield]] for up to 24 feeders including checking feeder state plus some extra ADC in and power outputs
  * alternative shield [[maschine:pickandplace:feeder:0816feeder:controller#controller-shield_for_arduino_mega|arduino mega sensor shield 2.0]] for up to 48 feeders without extras
  * [[maschine:pickandplace:feeder:0816feeder:controller|arduino firmware]] to interpret G-Codes received from OpenPnP to trigger a feed and configure feeder
