High Precision PCB Fab Service With Line Width Spacing Regulation
Unrivaled PCB Fabrication Delivering Top Quality And Flexibility
Printed Circuit Board Fabrication Description:
Welcome to our premium Printed Circuit Board Fabrication services, where we emphasize both quality and versatility. Our PCBs are strong and flexible, featuring an array of reinforcing materials, such as PI, FR4, and steel sheets.
We demonstrate adeptness in handling substantial projects, providing a noteworthy size capacity of up to 500MM*1000MM. Our varied insulation materials, including FR4 board, copper substrate, and PET, deliver exceptional electrical performance and maximum heat resistance.
Our dedication to exactness is evident in our stringent regulation of line width and spacing, supplemented by a wide range of solder mask options. We offer both mechanical and laser drilling to ensure precise and neat board cuts, as well as an array of surface treatments for additional protection and enhanced aesthetics.
Our service integrates unique procedures such as thick copper plates and high-frequency plates, alongside adaptable molding techniques like V-cut, CNC, and laser. Rely on our PCB Fabrication service for unparalleled quality, adaptability, and precision, meticulously tailored to meet the needs of your intricate projects.
