Sure, here's the translation of the list of machinery used in PCB board processing into English:
The PCB board manufacturing process utilizes a diverse range of machinery, each contributing to the production's quality and efficiency. Here are some of the key machines and their primary functions involved in PCB board processing:
Cutter: Used to cut large sheets of material into smaller boards suitable for production, typically with automatic or semi-automatic precision cutting.
Drilling Machine: Performs drilling operations on the PCB board to create holes for component insertion and soldering. The holes must be precise to ensure accurate circuit connections.
Deburring Machine: Removes burrs and debris generated during drilling, ensuring smooth and clean hole walls.
Inkjet Printer: Prints the circuit pattern onto the PCB board, serving as the foundation for board fabrication. High-precision print heads and control systems are essential for clear and accurate patterns.
Exposure Unit: Transfers the printed circuit pattern onto a special photosensitive film through UV exposure. Tight control over exposure time and intensity is crucial for pattern integrity and resolution.
Developer: Removes the unexposed portion of the photosensitive film, leaving behind a clear circuit pattern. The developer's chemistry and process time significantly impact the final pattern's quality.
Plating Line: Applies a conductive metal (such as copper) coating to the PCB board's holes and surfaces, enhancing conductivity and mechanical strength. Strict control over current density, temperature, and plating solution composition is essential.
Etching Machine: Removes excess metal from the PCB board, leaving only the desired circuit pattern through chemical etching. Etchant formulation and etching time must be carefully controlled for optimal results.
Solder Mask Printer: Applies an insulating green solder mask to the PCB board's surface, protecting the circuitry from the environment. Solder mask selection and printing thickness depend on product requirements.
Solder Mask Curing Oven: Cures the printed solder mask on the PCB board through heating, enhancing adhesion and insulation properties. Curing temperature and time must be precisely controlled based on the solder mask's properties and product requirements.
Silkscreen Printer: Prints text, symbols, or logos onto the PCB board's surface for component placement and maintenance. Ink selection and printing techniques impact the final print quality.
Sandblaster: Removes impurities and oxides from the PCB board's surface through sandblasting, improving flatness and adhesion. Sandblasting media and pressure adjustments depend on the board's material and surface condition.
Gold Plating Line for Gold Fingers: Applies a gold plating to the PCB board's gold fingers, enhancing conductivity and corrosion resistance. Gold plating solution composition, temperature, and current density require tight control.
Flying Probe Tester: Tests the PCB board's circuit connectivity and performance by contacting test points with high-speed flying probes. Known for its precision, efficiency, and reliability, it's an essential testing device in PCB production.
Universal/Specialty Testers: Conduct functional and performance testing of PCB boards based on specific product requirements. Universal testers cater to various PCB board types, while specialty testers focus on specific board sizes or specifications.
Burn-in Test Equipment: Simulates the PCB board's operational environment over an extended period to test its stability and reliability. The equipment adjusts temperature, humidity, and voltage to suit testing conditions.
Cleaning Equipment: Cleans PCB boards throughout the production process, removing surface contaminants and residues. Methods include water washing, chemical cleaning, or ultrasonic cleaning, chosen based on the contaminant's nature and cleaning requirements.
Packaging Equipment: Packages completed PCB boards for storage and transportation. The equipment can automatically or semi-automatically package boards based on their size and shape, such as vacuum packaging or shock-resistant packaging.
Additionally, PCB factories employ auxiliary equipment to support the smooth operation of the production process, including air compressors, drying equipment, ventilation and dust removal systems, and material handling equipment. These components collectively form an efficient and precise production system, ensuring the quality and efficiency of PCB board manufacturing.
