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.




A-TECH buried vias pcb will be tested adopting a series of standards. Its mechanical parts, materials, and the whole structure will be tested to check their mechanical properties and defections. Its display screen is equipped with a long-live monochrome light source
Quality inspection of A-TECH buried vias pcb will be conducted strictly. Its dimensional tolerance, form and location tolerance, surface roughness, and thermal treatment quality will be checked using high-tech testing machines. According to the usage environment, it can be designed with a self-cleaning function
The quality of A-TECH buried vias pcb is guaranteed by various standards that it has passed. It is manufactured in line with requirements for different aspects of GB/T and JB/T. It has advantages such as control output and strong data storage capabilities
A-TECH buried vias pcb goes through a series of production processes. They involve CAD/CAM design, prototyping, milling, turning, fabrication, welding, spraying, and commissioning. Its shell is made to be highly wear-resistant
The design of A-TECH countersink pcb follow these basic steps: recognition of its need or purpose, selection of a possible mechanism, analysis of forces, material selection, design of elements (sizes and stresses), detailed drawing, etc. Its accuracy and high precision contribute to its low detection limit
Professional testing allows buried vias pcb to be optimal. The product has achieved the maintenance-free performance
