Product Description

2-layer lead-free HASL PLC industrial control

Product Overview

2-layer lead-free HASL PLC industrial control board designed for reliable performance in industrial automation applications.

Key Specifications

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.
