Although a Printed Circuit Board (PCB) in PCB factory china is a common term in the electrical and electronics arena, few are aware of its origins, requirements. Before PCBs evolved to their present state, components had to be interconnected by wiring from one point to another. Not only was this laborious, but also susceptible to frequent failures at junctions and places where wire insulation aged and cracked and formed short circuits.

This led people in PCB factory china to move on to wire wrapping. They wrapped a small gauge wire around a metal post at individual connection points. This created a connection, which was highly durable, gas-tight, and easily changeable.

However, with electronics moving towards integrated circuits, and SMDs, the number and complexity of electronic components in gadgets increased to a great extent, while consumers wanted reductions in the size and cost of electronic products. To meet these demands, designers and manufacturers developed the printed circuit board or PCB in PCB factory china.

Functions of a PCB

A PCB replaces the point-to-point wire connections with copper traces printed on to a non-conducting board or substrate, hence the name. The PCB also has space for mounting the other required electronic components onboard, and this makes the soldered PCB a major subassembly within an electronic device today. Apart from mechanically anchoring the components to the PCB, solder also forms a good electrical connection between the component leads and copper traces on the PCB.

Types of PCBs

Single-sided PCBs have the copper traces only on one side of the non-conducting substrate. To accommodate circuits of higher complexity on smaller boards, the single-sided PCB soon gave way to double-sided ones, where the copper traces were present on both sides of the substrate. As circuit complexity increased further, designers went on to design PCBs n multiple layers, with vias to interconnect the copper traces on each layer. The complexity of modern computer boards today requires them to accommodate as many as 16+ layers,Sun&Lynn PCB factory china could produce 40layers PCB.

Advantages of using PCBs

A PCB offers a solid surface on which to mount components that make up an electronic equipment, in an organized and orderly manner. The PCB also provides the required insulation between components to allow them to function properly and dissipate heat. In short, a PCB is one of the factors allowing designers to make smaller and more compact electronic equipment.
