are required to check carefully. Its electromagnetic compatibility, static, harmonic, and other electric issues which may affect the operation of other devices will be handled properly. 2.
This product is non-toxic and does no harm. Any harmful substance, such as formaldehyde have been eliminated or processed to a very negligible level. 3.
One of the customers said that the product offers significant savings over its lifetime since it utilizes less energy and lasts longer. 4.
This product is an essential part of the most majority of electronic assemblies, power electronic devices, and optoelectronic components.
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.
