More complex printed circuit board specifications, product variety, generally in accordance with PCB layers, flexibility and material classification. Layers can be divided into: single-sided, double-sided and multi-layer boards; distinguished by softness for rigid printed circuit boards and flexible printed circuit boards; according to the material may be divided into several categories as shown in the chart below.
From PCB layers and direction, the PCB industry is divided into single-sided, double-sided, conventional multilayer, flexible boards, HDI (high density interconnection) sheets, 6 major product segments such as package substrate. From the product life cycle "start-up period-period-
Maturity-the recession "4 cycles, such as dimensions, single panel, double panel because they do not fit the current short thin application trends of electronic products, is in recession, the proportion of his output decreased in developed countries and regions such as Japan, and Korea and China's Taiwan has rarely produced the products here at home, many manufacturers have made it clear that they no longer received single and double panel.
