About Double Sided PCB Board and Prototyping

Double sided pcb board has 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:

Double-sided board with plated through-hole connection (PTH) Double-sided board without plated through-hole connection (non-PTH)

Double-sided PTH board has circuitry on both sides of an insulating substrate, which is connected by metalizing the wall of a hole in the substrate that intersects the circuitry on both sides. This technology, which is the basis for most printed circuits produced, is becoming popular in cases where the circuit complexity and density is high.

Double-sided non-PTH board is only an extension of a single sided pcb. Its cost is considerably lower because plating can be avoided. In this case, through contacts are made by soldering the component leads on both sides of the board, wherever required. In the layout design of such boards, the number of solder joints on the component side should be kept to a minimum to facilitate component removal, if required. It is generally recommended that conductors should be realized as much as possible on the non-component side and only the remaining should be placed on the component side.

The software required to design circuit board usually is supplied to the user at little or no cost, as of 2011. Most circuit board manufacturers also allow the user to purchase several prototype boards, or they can be mass-produced. The difference between a custom circuit board and a regular circuit board can be small or great, depending on the user's needs.

When someone makes a circuit board, there are many different printed circuit board supplies that can be used to make this task easier. Blank boards are boards without any circuitry that are ready for custom circuits.
