For Single-sided PCB, the components are on one side, conducting wires are on the other side, single sided PCB is the most simple and basic PCB board.
With the appearance of electronic transistor, single sided PCB was developed in the early of 1950, which is mainly manufactured in USA. Single-sided PCB was manufactured by copper etching directly at that time. During 1953 to 1955, Japan use imported copper make out paper phenolic aldehyde copper substrate, and apply mainly on radio products. In 1956, single-sided PCB technology was made big progress with the appearance of professional PCB manufacturers from Japan. In the early stage, copper substrate mainly used paper phenolic aldehyde, but because paper phenolic aldehyde with the factors of low electric insulation, bad solder thermal stability, twist issue etc, paper epoxide resin and glass fiber epoxy resin was developed soon after. Currently, paper epoxide resin is widely used in consuming electronic.
Basically, there is no challenge for PCB manufacturer to produce single sided PCB and the technology is quite mature nowadays. The main focus for PCB manufacturer is how to control production cost and save more cost for customers.
A-TECH CIRCUITS is able to supply large quantity single sided PCB with quite low pricing, the raw material for manufacturing single sided PCB include FR1, CEM1, CEM3 and FR4.
