Company Advantages
1. The design of A-TECH via in pad technology is finished with high quality. It gives consideration to the contrast and consistency of dimension and the contrast and consistency of direction that aims to achieve rich change in spatial organization.
2. The product emits more lumens per watt than incandescent light bulbs and it is not affected by its shape and size, which makes it flexible in a lighting application.
3. A-TECH CIRCUITS Co., Ltd.'s years of development and exploration have developed various edge plating pcb of different types.
4. A-TECH's R&D team specializes in the design of highly stable edge plating pcb products.

Impedance is the combination of the capacitance and inductance of a circuit when operated at high frequency. Control impedance in printed circuit boards are used across a broad range of applications to help ensure high signal integrity. Basically there are usually three types of impedance in PCB designs like single-ended impedance, differential impedance and coplanar impedance.

The factors affect impedance include: impedance trace width/spacing, copper thickness, dielectric thickness on either side of the impedance traces, dielectric constant of the core and prepreg material etc.

The applications of impedance control PCB include RF communication, Signal processing, High quality analog video, Computing 100MHz and above, Telecommunications and so on.

A large proportion of multilayer PCBs that A-TECH manufactured are with impedance control requirements, normally we will calculate impedance based on stack up and gerber designs to match with specified impedance values, our engineering dept might do necessary adjustments on stack up or impedance trace width/spacing if there is any mismatch after calculation. Moreover, the impedance coupons will be placed in each working panel which use for testing impedance values before shipment.
