2. A-TECH CIRCUITS Co., Ltd. is committed to promoting continuous technological advancement. A smooth part is added on its PTH line to reduce the roughness of through hole
3. The product has good mechanical properties. It has both good relative hardness (Mohs scale) and absolute hardness, which makes it resistant to the exterior impact. It has high tensile strength and can be deformed without breakage
4. The product can be flexibly configured to work as sales-promotion showstoppers, regardless of where it is set: in a supermarket, pharmacy or beauty parlor. Its solderable surface is protected from the oxidation
5. The product is temperature resistant. It is used in high-temperature applications without affecting its physical or chemical properties. It is characterized by high thermal conductivity and good heat dissipation

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.
