Why Firms Decide To Use PCB Design Services

By Andrea Davidson


Everywhere that a person looks they are confronted by a device which uses electrical power. Most will contain electronic components, but not many people will be aware how these components interact to produce a desired result. Businesses know what they want a product to do, and the smarter businesses will make use of specialist PCB design services.

Deciding to operate in this way does come with several advantages. It means that a business doesn't have to set up such a department of their own. Using an external specialist firm takes away any need for this.

An initial consultation will take place with the company. This is to find out exactly what they want their product to do, and how they wish to achieve it. At this point the available space can be measured. This can have as much of a bearing on things as the product requirement.

When confronted by space, or weight, limitations often the solution is to use something known as a surface mount printed circuit board. All this means is that the components are fixed directly onto the surface of one of these boards. They can utilise just one side of the board or both should the need arise. With the components being smaller, a smaller board can be made and so weight is also kept to a minimum.

The other type of circuit board commonly used is called a through board. The electronic components are larger, so are easier to see but they do need more room and they weigh more. The component body is on one side of the circuit board, the legs pass through the board before being soldered onto the metal tracks located on the other side of these circuit boards.

As mentioned earlier the dimensions that the populated circuit board has to fit into are very important. This effectively limits the size of the board that the specialists have to work with. They will begin to devise the circuit plan, one important factor being how will the required power get to this newly designed circuit.

If a through board is used as an example, the power can be introduced to the metal tracks in one of two ways. Wires can be fed directly between the power supply and the relevant tracks. Or the board can be mounted directly onto a socket, and power fed in that way. Power moves along the tracks, should it meet a component leg it is then diverted in that direction, and will cause the component to operate.

The voltage itself might be limited, or increased, depending on the component and how it is connected. It could trigger an integrated circuit, or cause a relay to either open or close. As you can imagine the world of electronics can be difficult for the average person to understand.

Therefore it is not surprising that industry and businesses decide to make use of these specialised PCB design services. They are the experts in the field and know how to use these components to gain full advantage. They will even make sure that the costs are kept to a minimum for the business.
