PCB Impedance Control

As PCB signal switching speeds continue to grow, today's PCB designers need to understand and control the impedance of PCB traces.

Difference between HDI board and normal pcb

Printed circuit boards, which are important electronic components, are the support body of electronic components and the carrier of electrical connections of electronic components

PCB board eight kinds of surface treatment process

The most basic purpose of PCB surface treatment is to ensure good solderability or electrical properties.

The difference between PCB prototyping and board making

PCB proofing is the printed circuit board in mass production before the trial production, generally refers to electronic products in the engineer design is completed, sent to the pcb manufacturer processing into pcb board.
