Specs

2018-03-08: mcmaster has two units on the way. One sourced locally at auction, one being shipped eBay freight. The eBay unit is pretty complete, although cosmetically isn't as nice. The local unit is reasonably complete, but may be missing a few simple bits like the wedge.

2018-03-15: both units have arrive. FabExchange unit unfortunately in much worse condition than I thought based on the pictures. For example, the inside electronics have been stripped out, and really the unit is just mostly taped together and missing a lot of screws. Its also missing drive belts and misc other covers. Fortunately the eBay unit, although has some missing paint and a little rust, is otherwise in pretty good condition. Preliminary tests indicate that it likely works

2018-03-25: contacted K&S, was told: “K&S no longer offers any manual wire bonder products and has ceased all related support services. You may want to contact Sharon Siso (…@mpptools.com) from MPP.”

Initial checkout

  • Bonding cycle: okay. I hear it feeding wire, I see the clamp releasing, it goes though 1/2 (initial/finish) cycle, does a ball forming motion, etc
    • Tried both the mouse and lever
    • However, pulley band old / rigid and snapped after a little use. Need to replace
  • Heated plate: heats
  • EFO or w/e its called: flickering red power LED. I haven't tested EFO specifically, will have to see if its actually working once I get wire
  • Targeting light: turns on, but I'm not seeing a reticle. Maybe needs some adjustment
  • Goose neck illumination: seems to work
  • TODO
    • Order replacement pulley belt
    • Order (gold) wire (size?)
    • Investigate tip. Is it okay? Should I order spare/replacement?
    • Order spare bulbs?

Resolution: scrap for other unit. Too many missing parts / things wrong to consider repair

Controllers

  • KTC-101-1: 115 VAC
  • KTC-101-2: 230 VAC

Belt repair

Belt broke shortly after I started using it due to it being old and what not

Measured:

  • 1/8” tube diameter
  • 8.5“ long ⇒ 2.8” OD
  • polyurethane

McMaster doesn't sell OD below 4“, so need to make one myself. I've ordered 1/8” material and will try to fit and join it. Suggestion is to fit it on the machine to length, then cut to allow for 10% stretching (ie cut 10% off).
