The gateway to higher technology applications are the circuits that are called double sided PCBs. This printed circuit boards are also known as double sided or double side plated thru circuits. For closer routing traces, they allow the alternating top and bottom layer procedure using visa. In today’s time the double layer printed circuit boards are quite famous and most often used in almost all technology related industries.
As the double layer or double sided printed circuit boards have twice the area for the conductor pattern in comparison to the single layer printed circuit boards, they are far better suited for the complex electronic circuits. These PCBs have conductors on both sides of the board and thus having two different conductor’s pattern will need an electrical connection between both the layers.
The double layer PCBs and single layer PCBs are almost similar in designing and manufacturing. The difference is that the single layer printed circuit board has a copper on only single side of the board, whereas the double sided has on both side. The single sided PCB will not have a copper plate in the drilled holes.
The base of manufacturing PCBs is the rigid fiberglass lamination, which is the raw material used as the foundation of the PCB. There are many types of printed circuit board materials used while the manufacturing process is going on. In order to meet the electrical temperature and other properties while manufacturing the PCBs the designer chooses which material is suitable for the particular circuit board. The standard material used is the fiberglass, which is often referred as FR4.
There are multiple applications for old and new designs of the double layer PCBs. The DSPT application requirements include fine line surface mount, ultra-high copper build, high and low temperature, solder coated, silver, and gold finishes, and many more.
