The center of gravity of the entire board should be close to the geometric center of the PCB. The center of gravity should not be allowed to drift to the edge of the board (1/4 area).
Analysis of the causes of pcb board anomalies such as white spots, microcracks, bubbles and delamination in PCB manufacturing process
Image of local separation caused by local expansion between layers of substrate or between substrate and conductive foil or between substrate and protective coating.
This article will effectively take you through the stages of the printed circuit board design process, but will focus more on the etching and stripping process of the board.
If the design rules do not meet the requirements of PCB manufacturing process, it will not only affect the function of the product so simple, even can not process can not realize the design intention of the engineer.
Before PCBS, circuits were made up of point-to-point wiring. The reliability of this method is very low, because as the circuit ages, the rupture of the line will cause the line node to break or short.

The rigid-flex PCB manufacturing process involves multiple steps including substrate preparation, circuit pattern generation, overlays, cutting flex, electrical testing, and verification.
With the current increase in PCBA capabilities and smaller sizes, you can assume that single-layer boards are effectively obsolete. In fact, these boards are used in many common products such as printers, digital cameras, calculators, stereos, and some po
