High End Printed Circuit Board Fabrication PI Polycumimine Board
High-End PCB Fabrication Guaranteeing Superior Quality And
Adaptability
Printed Circuit Board Fabrication Description:
Introducing our high-end Printed Circuit Board Fabrication services, where we produce durable and highly flexible PCBs using various reinforcement materials, including PI, FR4, and steel sheet.
Equipped to manage large-scale projects, we offer a maximum size capacity of up to 500MM*1000MM. The broad array of insulation materials we employ, including FR4 board, copper substrate, and PET, ensures outstanding electrical performance and excellent heat resistance.
Precision is our motto, evident in our meticulous line width and spacing control, complemented by a comprehensive variety of solder mask options. We apply both mechanical and laser drilling techniques for precise and clean board cuts, along with an extensive selection of surface treatments for enhanced durability and aesthetic appeal.
Our service encompasses special processes like thick copper plates and high-frequency plates, supported by versatile molding methods such as V-cut, CNC, and laser. Trust in our PCB Fabrication service for superior quality, adaptability, and precision, perfectly tailored to cater to the demands of your complex projects.
