  • Product Description
PCB Solder Mask Removal Laser System | Chanxan Laser

Precise PCB Solder Mask Removal System

In PCB manufacturing, coating removal is used to selectively eliminate solder mask layers and other surface coatings to expose underlying copper pads, enable electrical connections, or prepare bonding areas. Traditional mechanical or chemical methods often introduce contamination, dimensional instability, or substrate damage. The Chanxan Picosecond Laser System is engineered for precise PCB solder mask removal, FPC fine window opening, and high-end selective coating ablation applications. Built on ultrafast picosecond laser technology, the system delivers true "cold processing", enabling non-thermal material removal with virtually no damage to underlying copper traces or dielectric layers. It is designed for advanced electronics manufacturing where zero thermal impact, ultra-clean edges, and micron-level accuracy are required.

Why Picosecond Laser for PCB Solder Mask Removal?

Nanosecond Laser Systems

  • Heat-affected zone (HAZ) causing thermal damage

  • Risk of copper oxidation and substrate delamination

  • Lower edge quality with potential burrs and debris

  • Thermal stress accumulation in fine-pitch structures

  • Limited suitability for advanced HDI and ultra-fine pitch applications

Picosecond Laser Processing

  • Near-zero heat-affected zone (HAZ) with superior copper protection

  • Non-thermal ablation eliminates thermal stress and delamination risk

  • Higher edge quality for micro-scale features with clean, burr-free openings

  • Ultrashort pulse duration significantly reduces heat diffusion

  • Ultimate solution for high-end PCB manufacturing where quality outweighs cost
