Easy to understand the classification of circuit boards

According to the circuit board layer to the right is divided into single panel, double sided and multilayer circuit board, three classifications.
The first is a single panel, in the most basic PCB, the parts are concentrated in one side, the wire is concentrated on the other side. Because the wire only appears on one side, the PCB is called a single sided circuit board. The single panel is usually simple and low cost, but the disadvantage is that it can not be applied to the product.
The dual panel is an extension of the single panel, when the single layer wiring can not meet the needs of electronic products, it is necessary to use a double-sided board. Both sides are covered with copper wire, and can pass through the hole to guide the two layer between the lines, so that the formation of the required network connection.
A multilayer board is a printed board with three layers of conductive pattern layer and insulating material which are laminated and formed with a layer of insulating material. Multilayer circuit board of electronic information technology to the product of the high speed, multi function, large capacity, small volume, thin, lightweight direction.
According to the characteristics of the circuit board if divide into soft board (FPC), and (PCB), flex board (FPCB).

PCB Design, Manufacturing & Assembling

In this article, you'll get to know the fundamentals of PCB manufacturers and how our company "PCBSKY" is unique from other manufacturers in China. What are the three main aspects of the PCB industry?   According to our experience of more than 10 years as the leading PCB Company in the industry, we can easily write that three main aspects in the PCB industry for which most clients look for are: PCB Design PCB Manufacturing  PCB Assembly Design, Manufacturing, and assembling of PCB is a systematic method for examining the parts and components which is needed to execute. It included obtaining costs of a commodity and seeks to cut costs before actual development begins. There are specific manufacturing, design, and assembling principles required to be following during the PCB process execution of any electrical or electronics part. Eventually, a final design concludes the series with a review among the most common issues related to the PC Board or Printed Circuit Board.

What is the POFV process of PCB? Why use POFV technology?

Image
The process flow of POFV has become more and more widely used in the PCB industry in recent years, especially in some products with high layers and large board thickness, which is very popular. People hope to use resin plug holes to solve a series of problems that cannot be solved by using green oil plug holes or pressure-filled resin. However, due to the characteristics of the resin itself used in this process, many difficulties need to be overcome in manufacturing to achieve good quality resin plug products. With the continuous updating of electronic product technology, the structure and installation method of electronic chips are constantly improving and changing. Its development is basically from components with plug-in feet to highly dense integrated circuit modules using ball matrix arrangement of solder joints. You can see the development history of parts from the following figure: In the PCB industry, many process methods have been widely used in the industry, and peop
