Single-sided PCB
Apr 6th
Single-sided PCB means that wiring is available only on one side of the insulating substrate. The side which contains the circuit pattern is called the solder side whereas the other side is called the component side.
These types of boards are mostly used in case of simple circuitry and where the manufacturing costs are to be kept at a minimum. Nevertheless, they represent a large volume of printed boards currently produced for professional and non-professional grades. (more…)
Multilayer PCB
Apr 6th
A multilayer PCB board is used in situations where the density of connections needed is too high to be handled by two layers or where there are other reasons such as accurate control of line impedances or for earth screening. The multi-layer board makes use of more than two printed circuit boards with a thin layer of what is known as ‘prepreg’ material placed between each layer, thus making a sandwich assembly. (more…)
Printed Circuit Boards Classification
Apr 6th
Printed Circuit Boards may be classified (PCB classification) according to their various attributes. They were traditionally divided into three classes according to their use and applications, and were commonly referred to as consumer, professional and high reliability boards. (more…)
