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.

If the space is limited then the printed circuit board will probably be of the type known as surface mount. The electronic components are mounted on the surface of the circuit board. The circuitry can either be single sided or dual sided. The components on this type of board are much smaller, and as a consequence take up less room and have less of a weight impact.

Another common form of Circuit board is called a through board. These are often bigger, as the components themselves are larger. The body of the electronic component is on one side of the board, the component legs are passed through the board, and soldered to the metal tracks on the opposing side. These types will need more room, and are a little heavier.

Space is a critical factor, as mentioned earlier. The specialist team needs to know how big, or small, they need to make the circuit board. With the dimensions in hand the planning of the circuit can get underway. One initial concern that needs addressing is the location of the power source.

The power supply is normally overcome in a couple of different ways. Often wires are used to link the power supply directly to the new circuit board. The other method is to connect the board into a socket, pads will connect the board itself with sprung pins within the socket body, and then on to the metal tracks. It travels via these tracks until it meets the soldered leg of a component, and it will then cause that component to operate.

This might reduce the voltage so that it is safe to operate an integrated circuit further on in the circuit design. It might open or close a relay to allow power to halt or to flow elsewhere. It might need to build up to a certain level before it can be released. The field of electronics can be quite complex at times.

This is why many businesses feel that it is worthwhile using specialist PCB design services. They understand the ways of the electronic components, and how they can best be utilised. They will endeavour to make the item do what the customer wishes, while at the same time keeping the cost down.
