Overall Strategies

Machine

• Z axis
• XY stage
• Toolhead
  • Pick head
    • 4th axis? probably good idea
  • Camera
  • ?macro camera?
    • Can dieID?
      • Do we need large camera and real lens? or can we get away with small module and m12 type lens?
• Up camera for part pick location verification?
• Wafer Frame holder
  • is gravity or similar confinement good enough
    • ? or do we need to have some kind of mechanism to hold/locate
• Overall base/ mount

Feeders

• 40x feeders total
• Mountable as 20x units
  • individually feedable?
  • ??or feed with movable feeder thing?
• Reel take up
  • friction wheels on single bar?
    • I am imagining all reels to fit on a single bar and all reels on like a kebab
      • Similar for tape seal tensioner
    • These can fit into reel hub and maybe have hex interior
• Tape Sealing
  • Hopefully this can be had by some fancy bent metal
    • Form laser cut steel and anneal
• Feed mechanism
  • Hopefully this can be pin indexed.
  • If not maybe an indexed pinned wheel if we need more force due to friction from tape sealer
  • last resort individual mechanisms

Software

• Machine setup/ calibration
  • Find wafer and map dies
    • calibrate machine
  • find feeder locations
• Pick place schema
  • coordinate reticles
  • track pick order and wafer #
  • create pick map
• Die location verification on pick
• Die place verification in tape
  • Can we also do dieID verification here too?
• Machine GUI
  • machine state
  • reticle/pick map
  • feeder states and manual control
  • overall completion table/ maybe with visual
• Machine readable data export with reel maps and other useful statistics

Shipping Crate

• Ideally breaks down to something as small as possible.

Stretch Goals

• Automatic wafer frame un/loading
  • simplest version can have 2 slots, one for completed die and one for the next die
  • this can allow the machine to complete and start next die as cycle time is measured in hours
