High Frequency PCB

1.Multi-layer PTFE laminating enables super high frequency PCB;

2.Laser cutting technology for PTFE laminates can ensure the high accuracy of outlines;

3.Plasma excitation can improve the adhesion of cooper in PTH for those high-frequency laminates and hence improve the reliability of inner-outer layer connection;

4.Special techniques like stepped milling, laser blind-buried holes (HDI) are available for high-frequency PCB;

5.Our lamination technology enables the mixture of high-frequency laminates, high-speed laminates, FR4, PI, metal laminates and other materials.
