Critical Production Processes
- Circuitry is formed directly on outer copper foil, requiring high-quality dry film lamination
- Vacuum lamination technology recommended to prevent bubble generation
- LDI (Laser Direct Imaging) equipment ensures line width tolerance within ±10%
- 100% AOI inspection after etching to detect undercuts and shorts
- Micro-etching roughening required before lead-free HASL (depth: 1.5-2.5μm)
- Board baking at 120°C for 1 hour to remove moisture and prevent solder splash
- HASL process controls vertical withdrawal speed for uniform tin layer thickness (±5μm)
- Flying probe testing for 100% electrical testing to detect opens and shorts
This PLC board is typically used for simple I/O control units, balancing cost sensitivity with reliability requirements.
