Equipment Benchmarking Example for Low-Volume Pick and Place

Our first example is for a low-volume assembler. Here are the details:

  • Annual board requirement: 10,500
  • Unique components per board: 43
  • Placements per board: 225
  • Board length: 7"
  • Board width: 5"
  • Minimum size component: 0603
  • Maximum size component: SOIC8 (4.9mm X 6mm)
  • Fine pitch requirement: 0.050"

And here is the chart comparing the assembler's requirements against a specific pick and place machine:

  PCB Requirement Equipment Data
Feeder Slots PCB Example 01 Model: MC-400
Feeder Slots Required 44 (42-8mm, 1-12mm) 64-8mm slots
Tube/Stick Parts 0 10-lane feeder requires 9 feeder slots
Matrix Tray Parts 0 Up to 3 trays in PCB area (trays reduce placement area)
Component Handling
Smallest Part 0603 0201 (w/nozzle)
Largest Part SOIC8 100 x 150 mm (3.94" x 5.9")
Smallest lead pitch 0.050" 15 mil (0.015")
Board Handling
Board Size Minimum 5" x 7" 2" x 2"
Board Size Maximum   (415 x 320 mm) 16.3" x 12.5"
Placement Speed Required
Board CPH Requirement 1350 2000 (IPC-9850 spec fo 2500 cph de-rated 20%)
