heavy edge plating pcb durable top supplier

Company Advantages
1. Many advanced sole making technologies are used in the production of A-TECH heavy copper pcb , such as CAD, CAM, as well as meta-mechanical analysis.
2. A-TECH CIRCUITS Co., Ltd. has strong technical strength and perfect sales network. It totally conforms to the UL Flame Rating of 94V-0
3. The product can allow significant water absorption and moisture transmission. It can absorb water vapor from the air and maintains its stability. A smooth part is added on its PTH line to reduce the roughness of through hole
4. The product is acid and alkali resistant. It has passed the test which requires it to be dipped into the acetic acid for more than hours. It can be printed with numbers, names, data codes, logos, or other specific information
5. The external surface of this product has enough brightness and smoothness. A gel coat is applied to the mold surface to achieve optimum surface finishes. It has high tensile strength and can be deformed without breakage

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.
