BOM file is one of necessary documents for PCB board assembly process, except other documents like PCB Gerber file, Pick and Place file, silkscreen file. For PCB designer, it is very important to create an effective BOM file to save time for PCB assembly house to make correct quotation for components and improve efficiency in … Continued
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
