Equipment Benchmarking Example for Mid-Volume Pick and Place
Our second example is for a mid-volume assembler. Here are the details:
- Annual board requirement: 22,000
- Unique components per board: 50
- Placements per board: 325
- Board length: 8"
- Board width: 10"
- Minimum size component: 0402
- Maximum size component: 28mm x 28mm
- Fine pitch requirement: 0.015" Lead Pitch QFP 256
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 02 | Model: MC-385V2V |
| Feeder Slots Required | 54 (45-8mm + 1 stick feeder) | 128-8mm slots |
| Tube/Stick Parts | 5 lanes | 10-lane feeder requires 9 slots |
| Matrix Tray Parts | 1 | |
| Component Handling | ||
| Smallest Part | 0402 | 01005 (w/nozzle) |
| Largest Part | 28mm x 28mm | 150 mm x 100 mm |
| Smallest lead pitch | 0.015" | 0.012" |
| Board Handling | ||
| Board Size Minimum | 8" X 10" | 2" x 2" |
| Board Size Maximum | 13.8" x 17.1" w/o tray holder 12.6" x 8.6" w/tray holder |
|
| Placement Speed Required | ||
| Board CPH Requirement | 4225 cph | 4400 cph (IPC-9850 spec of 5500 detrated 20%) |
