From Manual Scraping to Laser Technology: How Shenzhen Highwah Intelligent Technology’s Laser Degumming & Mold Flash Removal Machines Redefine Precision Manufacturing

Inside semiconductor packaging workshops, a rice-grain-sized chip may be scrapped due to merely 0.1 mm of residual mold flash on its pins. On power module production lines, manual flash removal with copper scrapers has become a major bottleneck restricting output capacity. As precision manufacturing enters the micron-level era, traditional mechanical grinding and chemical etching can no longer meet stringent standards — yet laser degumming and mold flash removal machines are rewriting the rules of production with ultra-precise laser beams.

Subtractive Manufacturing via Laser Beams: The Core Logic of Non-Contact Removal

The operating principle of laser degumming and mold flash removal machines is sophisticated yet straightforward. A high energy density laser beam irradiates the adhesive layer, causing it to instantaneously absorb thermal energy, reach vaporization temperature, and undergo thermal decomposition or full vaporization. The entire process relies purely on thermal energy interaction, with no physical cutting tools contacting workpieces and no chemical reagents involved. This laser-based removal method differs fundamentally from conventional processes. Mechanical grinding removes adhesives through friction from sandpaper or grinding wheels, which constitutes destructive physical stripping. Chemical degumming dissolves adhesives using solvents, acids or alkaline solutions. In contrast, laser degumming avoids all physical contact with base materials, enabling precise energy control that vaporizes only the adhesive layer without altering the surface properties of substrates. Its non-contact, consumable-free and eco-friendly features render it uniquely advantageous for precision electronics, optical lenses and other components requiring intact surface finish.More importantly, laser degumming supports automated operation via pre-programmed scanning paths paired with vision positioning systems, capable of removing adhesive residues on curved surfaces, micro-holes and irregular complex structures. Operators can flexibly adjust laser power, spot size and scanning speed to match adhesives of varying thicknesses and material properties, efficiently eliminating thin micron-scale glue films as well as thick millimeter-level adhesive layers.

Four Core Advantages: Why Laser Equipment Is Replacing Traditional Processes

Laser degumming and mold flash removal machines deliver transformative improvements across four critical dimensions compared with conventional flash removal techniques.

1. Superior Precision The minimum laser spot diameter reaches 0.01 mm, enabling targeted processing of tiny flash residues. Highwah’s laser degumming equipment controls residual mold flash and burrs on packaging outlines within 0.1 mm, with no plating loss or copper exposure during adhesive removal.
2. Outstanding Productivity Laser scanning speeds range from 4,500 mm/s to 8,000 mm/s. Equipped with a dual-channel four-laser-head design, the machine simultaneously removes flash from both top and bottom surfaces, eliminating residual adhesive on pin sidewalls entirely.
3. Clean, Dry Processing Laser degumming is a dry manufacturing process that eliminates pre-treatment chemical softening and post-process high-pressure water rinsing. Integrated fume extraction systems treat vaporized adhesive waste, ensuring fully clean and pollution-free operation.
4. Unmatched Process Flexibility Simple, rapid equipment adjustments accommodate workpieces of diverse sizes and geometries. The system processes semiconductor components fabricated from metals, plastics, ceramics, glass and other substrate materials.

Wide Application Scope: Laser Degumming & Mold Flash Removal Machines Across Chips and Batteries

The application landscape of laser degumming equipment extends far beyond semiconductor packaging to broader precision manufacturing sectors.

• Semiconductor Packaging: The optimal solution for eliminating mold flash surrounding IC chips, IGBT modules and other packaged devices. Ideal for removing parting-line flash and pin residual glue on packaging & testing production lines that cannot be cleaned thoroughly by high-pressure water washing.
• Power Devices: Cleans residual adhesive on heat sinks of all types of power semiconductors.
• Medical Devices: Safely removes epoxy resin, UV glue and other adhesives without damaging medical components.
• New Energy Industry: Used for trimming excess adhesive on lithium battery cells.
• Electromagnetic Coils: Symmetrically paired primary and secondary laser units jointly remove surface adhesive residues on coil metals, with vision modules verifying complete processing quality.
