FR4 Printed Circuit Board Fabrication CNC Die Punching V Cut Laser
Printed Circuit Board Fabrication FR4 Board Die Punching
Printed Circuit Board Fabrication Description:
Immerse yourself in our top-tier Printed Circuit Board Fabrication services, where we construct resilient and highly adaptable PCBs using an extensive variety of reinforcement materials, such as PI, FR4, and steel sheets.
Skilled in overseeing expansive projects, we cater to a size capacity reaching up to 500MM*1000MM. We utilize a broad spectrum of insulation materials, including FR4 board, copper substrate, and PET, assuring outstanding electrical performance coupled with prime heat resistance.
At the heart of our operation lies precision, manifested in our meticulous management of line width and spacing, enriched by a comprehensive range of solder mask options. We employ both mechanical and laser drilling techniques for neat and accurate cuts, along with an assortment of surface treatments for increased durability and visual charm.
Our services also encompass specialized processes such as thick copper plates and high-frequency plates, alongside adaptable molding techniques like V-cut, CNC, and laser. Entrust our PCB Fabrication service for supreme quality, adaptability, and precision, proficiently tailored to accommodate the intricate demands of your projects.
