Product Feature And Application

High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter.

HASL is divided into two kinds of vertical and horizontal. It is generally believed that horizontal is better, mainly because the coating of horizontal HASL is more uniform, and can be achieved automated production. Thickness of HASL solder and flatness of pad is difficult to control,and it is difficult to mount a narrow pitch components. Lead-Free HASL: it replaces Pb-Sn with non-Pb-Sn metal or lead-free solder alloys.

The Min.line width and space are both 3mil. The Min hole is 0.1mm. This board also has impedance, so the requirement of line width and space is very very strict. The outline of this board is very strange, so it is easier to do the profile by using mould, not by laser.

Why X-PCB?

● With the capabilities to manufacturing precision PCB with min 0.1mm hole and 3mil/3mil of width and spacing.

● Agile production: Wide range of special base material supplying, making full use of the top resources in the field with high flexibility, helping customer to verify new materiasl and processes quickly.

● Design consultation: Professional Design For Manufacturing (DFM) Service, helping customers select the optimal solution from the prototype design phrase based on cost-saving and manufacturability.

● Our Values: Integrity-based, Focus on Profession, Commitment to Excellence.
