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%) |
