Company Advantages
1. The design of A-TECH impedance pcb takes many elements into consideration. The style, design, the model, materials are all the prime factors that prompt the designer to take due importance. A smooth part is added on its PTH line to reduce the roughness of through hole
2. The product creates a relatively stress-free lifestyle for workers. It helps reduce everyday task fatigue and improve their working efficiency. The product can be resistant to corrosion
3. The product is guaranteed to be of stable performance and long lifespan. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
4. This product has sturdy construction and durability and can be used for a long time. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo


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.
