The Technology behind PCB Manufacturing

pcbDesign for manufacture should not be the sole aim of PCB manufacturing companies whether they are in-house or contract firms. They should make their designs efficient and inexpensive too. The technology behind starting a PCB business is costly at first, but there may be a promise that the advanced technology brings – a promise to assure the clients that the firm with its technology will only produce PCBs that are of quality. While technology advances, there is also a change in the old ways of PCB fabrication. Today’s modern software produces layouts which meet exactly the client’s needs and make the PCB’s function accordingly.

There are two types of PCB manufacturing businesses, which are the in-house and contract. There is much complexity in a contract manufacturing firm as its processes require uniformity in the roles of its personnel. The technology that contract firms use is usually more advanced so that there will be no wastage of time for doing manual labor, if ever there is.

The client may have to place his or her order online by choosing the correct PCB details and quantity on the boxes, which is more often part of the quoting system, to start the process right away.  is also one stop solution for your online deals, you can place the order of your PCB product requirement by visiting this site. This is part of the computer-aided system that helps the firm correctly identify the specific client needs, and not to compromise the manufacturer and client relationship.

The world today demands more and more electronic devices such as mobile phones, laptops and others that we use in our everyday living. Therefore, there’s a need for a fast-paced innovative technology that will complete the order of clients and, at the same time, preserve the quality of PCB fabrication.

Almost all contract manufacturers are advanced in their technologies such that they use laser technology in drilling the holes on a board rather than do it manually, which technology is more precise and automated. The holes are drilled according to the specification no matter how minute they are, and the drilling process is done quickly. The accuracy and speed the laser technologies present are achieved despite the bulk orders of clients.

The designing team may be remotely located, but certain standards are set so that uniformity and teamwork are still achieved. The team analyzes and tests each design carefully to make sure that all parts of the PCB are working well and fast. Drilling and routing are the other important defining characteristics of PCBs and intricate processes in PCB fabrication. There is this through-hole technology in which the electronic components are mounted by inserting their leads through the holes. This technology is still used although it is replaced by surface-mount technology in majority of the electronics industry.


Through-hole technology seems to gain popularity in large electrical device manufacturing wherein surface-mount technology is more applicable on smaller device production. Through-hole technology requires the accurate drilling of many holes on the circuit boards, which is costly. On the other hand, surface-mount technology cuts costs as it enables the electronic components to be directly attached to the PCBs through reflow soldering. This type of soldering is the process of melting the solder glue on the electronic components to attach them permanently to the board.

Surface-mount technology is being used in the manufacture of PCBs in bulk. Large PCB manufacturing companies prefer surface-mount technology to through-hole technology to cut costs and at the same time provide increased electronic functionality and specificity.

This is useful for small PCB fabrication as it provides more space for the connection of copper tracks on the boards, reducing blockages and the tendency to make faulty connections. These mistakes are usually the result of inaccurate drilling and routing. The more holes the client requires, the more expensive the PCB will be.
