Company Advantages
1. A-TECH circuit board assembly has to go through a series of treating procedures of parts ranging from part selecting, cleaning, polishing, and other surface treating methods. All these procedures are separately inspected by different QC teams.
2. The product only has superior quality but also has stable performance that customers can count on.
3. As we put great importance on the quality management system, the quality of the product is fully guaranteed to meet the international standards.
4. All the products have passed the circuit board assembly certification and vippo pcb inspection.
5. A-TECH CIRCUITS Co., Ltd. have mature skills at circuit board assembly.

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.
