In the fields of semiconductor packaging and precision electronics manufacturing, the micro‑cleanliness of component surfaces directly determines product yield and reliability. As electronic products evolve toward miniaturization and high integration, traditional chemical cleaning and mechanical wiping processes can no longer meet stringent process requirements. Drawing on 14 years of technical expertise in industrial laser applications, Shanghai Shengtong Laser has launched a high‑precision laser cleaning solution, delivering a brand‑new green, non‑destructive and efficient approach for surface treatment of electronic components.
Electronic components feature delicate structures and sensitive materials; even minor physical stress or chemical corrosion may lead to functional failure. Shengtong high‑precision laser cleaning adopts high‑energy pulsed laser beams of specific wavelengths. Through the physical mechanism of converting light energy into shock waves, it instantly strips off surface oxides, flux residues and particulate contaminants. The whole process involves no contact with base materials, eliminating scratch risks caused by mechanical friction. It also prevents erosion of sensitive coatings by chemical reagents, enabling genuine pinpoint‑accurate cleaning operations.
I. Core Working Principle of Laser Cleaning for Rubber Molds
Shanghai Shengtong Laser Cleaning carries out oxidation cleaning operations for rubber molds relying on high‑frequency short‑pulse lasers. High‑energy beams of specific wavelengths are absorbed by rust layers, paint layers and contamination layers, generating rapidly expanding plasma together with shock waves. The shock waves shatter contaminants into fragments and remove them.
Different electronic components have significantly varying requirements for cleaning intensity and scope. The Shengtong laser cleaning system integrates an intelligent control platform, enabling flexible adjustment of core parameters such as pulse width, frequency and power. For workpieces with complex morphologies including chip lead frames and micro‑connectors, the equipment can perform automated cleaning via pre‑set trajectories to ensure high process consistency across batches. Whether removing carbonized flux invisible to the naked eye or stripping local plating layers, optimal results can be achieved by optimizing optical path design, balancing cleanliness and substrate integrity.
Against the backdrop of increasingly stringent environmental‑protection regulations, the zero‑consumable feature of laser cleaning serves as a key enabler for electronic manufacturing enterprises to transform and upgrade. Requiring no water‑based cleaning agents or acid‑alkali solvents, this process generates no wastewater or waste materials, greatly cutting hazardous‑waste disposal costs and easing environmental‑compliance burdens. Meanwhile, the equipment runs solely on electric power with no wearing‑part consumption, resulting in markedly lower long‑term operation and maintenance costs compared with conventional cleaning methods. When integrated into automated production lines, it reduces downtime for maintenance, boosts overall production efficiency, and delivers sustainable economic and environmental benefits for enterprises.
