Coplanar Waveguide is a type of PCB Impedance When it come to talk about PCB impedance, often it refer to talk single-end impedance,differential impedance.There is another type of impedance called co-planar impedance. What is co-planar impedance It is the impedance measured from signal track when it transmit the signals between GND and VCC zone. What … Continued
Via in pad is the design practice of placing a via in the copper landing pad of a component. Compared to standard PCB via routing, via in pad allows a design to use smaller component pitch sizes and further reduce the PCBs overall size. With component manufactures pushing smaller parts every year and the demand … Continued

How to choose surface treatment process for PCB between HASL, gold plating and immersion gold. The choice of surface treatment process depends mainly on the type of component that is finally assembled. And the surface treatment process will affect the production, assembly and end use of the PCB Surface treatment purpose The most basic purpose … Continued
PCB trace impedance is the sum of all the resistance and reactance components of an electrical signal path. An ideal transmission line must have a characteristic impedance that matches both the transmitter and receiver of the intended signal. If the characteristic impedance of the matched transmission line is faithfully maintained, then the full signal sent … Continued
With the development of high-end, miniaturized electronic products such as mobile phones, notebook computers and PDAs, the demand for flexible boards is increasing, and PCB manufacturers are accelerating the development of thinner, lighter and denser. 1.Single-layer FPC It has a layer of chemically etched conductive pattern. The conductive pattern layer on the surface of the … Continued
