printed circuit boards wiki
Wiki circuits - related electronic projects and circuit diagrams (schematics), this helps you finding desired informations and facilitates your site navigation through all articles database.
In every website page you will find a special section (at the beginning or the end) with tags just like this and also different tags associated with the current article.
Tags inter-links stories with the similar content, so if you click on the tag you will find only related and relevant Wiki content.
Double-sided PCB
Apr 6th
Double-sided printed circuit boards have wiring patterns on both sides of the insulating material, i.e. the circuit pattern is available both on the components side and the solder side. Obviously, the component density and the conductor lines are higher than the single-sided boards. Two types of double-sided boards are commonly used, which are: (more…)
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…)
