blind edge plating pcb castellation heavy durable for sale

Company Advantages
1. The production planning of A-TECH press fit pins pcb is flexible and efficient. It can reduce the electrical signal loss and provides the highest efficiency
2. A-TECH CIRCUITS Co., Ltd. is marketing with the A-TECH brand, and pays great attention to the reputation of its own brand. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. Its luster is related to the indices of absorption and refraction and the amount of dispersion from the crystal lattice, as well as the texture of its exposed surface. The product is certified under UL(E357001) and RoHS
4. This product features low energy consumption. It is designed with an optimized circuit arrangement which has less connecting wires to reduce energy loss during operation. It is characterized by high thermal conductivity and good heat dissipation
5. It yields best-in-class corrosion resistance. The choice of corrosion-resistant materials, the design against corrosion, and the application of coatings endow it with this property. It totally conforms to the UL Flame Rating of 94V-0

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.
