The cutting accuracy of PCBA cutting equipment is the core indicator to ensure the functional integrity and production yield of circuit boards. Its implementation depends on the comprehensive optimization of hardware design, software algorithms, process control, and environmental management. The following systematically explains how PCBA cutting equipment ensures cutting accuracy from three dimensions: key technology, process control, and environmental management:
Laser marking equipment forms permanent marks on the surface of materials through high-energy laser beams, and is widely used in product identification, anti-counterfeiting traceability, and process decoration. To ensure stable operation of equipment, meet quality standards for labeling, and ensure operational safety, strict control is required from four dimensions: equipment selection, operation standards, maintenance, and environmental management. The following are specific precautions:
Daily cleaning
Optical lens cleaning: Use a dust-free cloth dipped in isopropanol to wipe the focusing lens and reflector every week to avoid fingerprints and dust, which can reduce laser power.
Chamber dust removal: Clean the interior of the equipment with compressed air every month to prevent dust accumulation from affecting heat dissipation.
Workshop environment control
Temperature and humidity: Maintain 20-25 ℃ and 40-60% RH to prevent lens condensation or static electricity accumulation.
Shock absorption: The equipment foundation adopts shock-absorbing pads to avoid interference from nearby vibration sources such as stamping machines.
Ventilation: Install an exhaust system to ensure that the smoke concentration generated by laser processing is less than 1mg/m ³, in compliance with OSHA standards.
Medical equipment labeling
Biocompatibility: Choose non-toxic materials (such as 316L stainless steel) and pass ISO 10993 biocompatibility testing after labeling.
Cleanliness: After marking, use ultrasonic cleaning to remove residues and avoid particle contamination of implanted devices.
