Equipment Benchmarking Example for Mid-Volume/High-Mix Pick and Place

Our final example is for a mid-volume assembler dealing with a high component mix. Here are the details:

  • Annual board requirement: 19,500
  • Unique components per board: 89
  • Placements per board: 213
  • Board length: 12"
  • Board width: 10"
  • Minimum size component: 0201
  • Maximum size component: BGA208 (23mm X 23mm)
  • Fine pitch requirement: 0.050" Ball Pitch BGA 208

A machine's ability to hold multiple matrix tray parts will best accommodate the production need:

  PCB Requirement Equipment Data
Feeder Slots PCB Example 03 Model: MC-388
Feeder Slots Required 90 (81-8mm, 9-tube) 256-8mm slots
Tube/Stick Parts 8 Avail (subtract 9 slots per 10)
Matrix Tray Parts 4 3 to 6 avail., full JEDEC location
Component Handling
Smallest Part 0201 01005 (with nozzle)
Largest Part 23 mm x 23 mm 100 mm x 150 mm
Smallest lead pitch 0.050" 0.012"
Board Handling
Board Size Minimum 12" x 10" 2" x 2"
Board Size Maximum   12.5" x 47" with conveyor
12.5" x 43" without conveyor
(It would be 16" instead of 12.5" without the matrix trays)
Placement Speed Required
Board CPH Requirement 2556 cph 7350 cph (manufacturer's spec of 10,500 de-rated 30%)
