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."

Clamp solenoid
Section 6.1.5
Reccomended: 100g force at 5 mil gap
5 - 7 mil acceptable for 1-3 mil wire
Must be changed when loading different size wire
Use force gauge (scale?)
Adjust force with nut on right
Adjust distance with set screws on left

Figure 3-8 on page 20 has items labeled
EFO vertical
1 mil wire => 30-30 mils below capillary
Greater gap => smaller wire
To adjust: loosen knurled knob
EFO horizontal
4 mm to left of capillary tip
Loosen solenoid clamping screw
SHCS allen key: 77 mil
EFO overtravel
50-60 mil beyond capillary tip
Loosen solenoid ring set screws
SS allen key: 34 mil
Capillary adjustment
SHCS allen key: ? couldn't get one to fit. Using pliers to tighten...
diameter: 1.47 mm
thread: 1.25 / 4 = 0.3125 mm
Capillary diameter: 1/16"
Allen key inserted for alignment: 56 mil
63 mil diagonol vs 1/16" => 63 mil

mcmaster eBay
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

Type J TC
| Pin | Function | Wire color | Notes |
|---|---|---|---|
| 1 | TC | Shrouded silver | +/-? |
| 2 | Ground? | Yellow w/ green | |
| 3 | Coil | Yellow | |
| 4 | N/A | N/A | |
| 5 | N/A | N/A | |
| 6 | TC | Shrouded silver | |
| 7 | Coil | Yellow | |
| 8 | N/A | N/A | |
| 9 | N/A | N/A |
Tried both TC polarities. One read 32, other 37C. Hmm
Coil resistance: 78.4 ohm. Around 1.5A
Couldn't get ground wire continuity on anything
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).
