Pioneering Quick Turn PCB Fabrication With Good Heat Resistance
Pioneering PCB Fabrication Ensuring Peak Quality And Adaptability
Printed Circuit Board Fabrication Description:
Discover our pioneering Printed Circuit Board Fabrication services,
where we craft durable and highly versatile PCBs using an array of
reinforcement options like PI, FR4, and steel sheet.
Our expertise in managing expansive projects allows us to offer a
size capacity of up to 500MM*1000MM. We utilize a variety of
insulation materials, including FR4 board, copper substrate, and
PET, ensuring unmatched electrical performance and excellent heat
resistance.
Precision is our watchword, evident in our meticulous line width
and spacing control, complemented by a wide array of solder mask
options. We utilize both mechanical and laser drilling for precise
and clean board cuts, along with a diverse range of surface
treatments to ensure durability and aesthetic appeal.
We provide unique processes like thick copper plates and
high-frequency plates, supported by flexible molding methods such
as V-cut, CNC, and laser. Opt for our PCB Fabrication service for
unmatched quality, adaptability, and precision, expertly tailored
to meet the intricate requirements of your projects.
