MDC ECM97 pick and place system

I bought this machine in 2013 to assemble DiscFerret PCBs. It's turned into a project in itself!

The control PC is an old Pentium PC, with a Kumagai KP422 motion control card and an MDC custom 16-bit PC I/O card.

Unfortunately MDC Co. now appears to be out of business (as of late 2019), so parts availability is precisely nil. I am looking into the possibility of machining new nozzles.

  • Documentation and/or software for the Kumagai KP422 I/O card (I expect this will be in Japanese – this is fine!)
  • Source code for the ECM control software is apparently “in the wild” – this would be extremely useful!
  • Spare nozzles – any for the ECM series machines (ECM93, ECM95, ECM97, ECM98, ECM99, ECM Luna) will do.
  • Any documentation, software, etc. for the ECM series machines which I don't already have

Please email philpem@gmail.com if you have any of the above

  • ECM97 Console variant with Cyberoptics LaserAlign HD component alignment system, top-down teaching camera and automatic fiducial sensor (EYE sensor)
  • Two feeder mounts (front and back) for a total of 48 feeders
  • Mix of 8mm, 12mm and 18mm feeders
  • Vibratory feeder
  • PCB conveyor

Specifications according to this page:

  • Accuracy ± 0.1mm
  • Air supply 60psi (4.14bar, 4.22kgf/cm2)

  • Chip sizes: 0201 to 0804, SOIC/PLCC up to 20mm in length. Fine pitch to 20 mils (0.5mm).
  • Placement rate: Manufacturer's spec 3600cph, 4000cph under optimal conditions. (Realistically? Probably about half that)

Component documentation:

I have a complete hard drive image of my ECM97's PC, with various versions of the ECM software. I am working on extracting the necessary parts of the ECM driver software.

The ECM hard drive image contains the following additional tools:

  • Panasonic PANATERM servo driver configuration software
  • LaserAlign LA_VIEW software configured for the LaserAlign HD

Mekko was the UK sales/support contact for these machines, but no longer supplies them.

Manncorp sold them under alternative names, but will not provide any support without a service contract.

Possible addons/improvements:
