The single-sided pcb board is on the most basic PCB, the parts are concentrated on the one side, and the wires are concentrated on the other side. Because the board only appears on one of the sides, we call this PCB as single-sided pcb. Because the single-sided pcb has many strict restrictions on the design circuit (because there is only one side, the wiring between can not cross and must be around a separate path), so only early circuits use this type of board;

The wiring diagram of the single sided board is mainly screen printing (screen printing), that is, the resist is printed on the copper surface, after etching, mark the solder resist, and finally the part guide hole and shape of part are completed by punching.In addition, some small-scale and diversified products use photoresist to form a pattern.

What is single-sided board.single-sided circuit board, which is widely used in the assembly system of core components of various electronic equipment and is an indispensable part of normal operation of electronic equipment. Its importance is equivalent to the foundation of a building. Only with a single panel with excellent performance can we make better electronic products on this basis. It can be seen from the radio to the LCD TV internal structure. For non-professional friends, you may not know much about single-sided board materials. Don't worry, today I will give you a general knowledge about the single panel, including the material and characteristics of the single-sided board.

History of single-sided board

From 1953 to 1955, Japan used imported copper foil to make phenolic cellulose paper copper -clad laminates for the first time, which were widely used in radios. In 1956, after the appearance of professional Japanese circuit board manufacturers, the manufacturing technology of single-sided boards rapidly progressed. In terms of materials,phenolic cellulose paper copper -clad laminates were mainly used in the early days. 

However, due to factors such as low electrical insulation, poor soldering heat resistance, and twisting at the time, materials such as epoxide cellulose paper copper-clad laminates and epoxide woven glass fabric copper-clad laminates have development, the current single-sided board required for consumer electronic equipment, almost using phenolic cellulose paper copper -clad laminates.

Material of single-sided board

The single-sided printed circuit board is a product developed in the early 1950s with the emergence of transistors, focusing on the United States. At that time, the main production method was the direct etching method of copper foil as the mainstream.
