Knowing Some Basic Steps in the PCB Manufacturing Process

The printed circuit board (PCB) is generally used to interconnect the electronic components of any electronic gadgets such as television, cell phones, computers or hard drives by applying conductive pathways from copper sheets onto a non-conductive substrate. PCB is also referred to as etched wiring board (EWB) or printer wiring board (PWB).

PCB�s are inexpensive and easy to use. Although it requires a lot of layout and designs, still you can guarantee that the cost is much cheaper compared to other types of boards offered in the market. In fact, the manufacturing of PCB�s is much cheaper and faster for large volume production.

Things to Consider in the PCB Manufacturing Process

The printed circuit board manufacturing (PCBM) involves sophisticated series of operation and complex processing steps to produce single or multilayered printed circuit board. The manufacturing process can be either through mechanical, chemical, electrical or optical in nature. However, always keep in mind that though PCB emits limited pollution, still the process could produce significant amount of chemicals that could not only affect the body but also environment. Materials to be used in the PCB manufacturing process should be checked and considered before going through the actual process. The overall output of the PCB could be affected when materials to be used are not checked eagerly especially in the boarding process.

Steps in the PCB Manufacturing Process

The very first step in building PCB is to set up the materials, process and requirements that meet with the client�s specifications about the board design.

The next step is the transferring of data. This process involves transferring of the data for a coating onto the etch film placed on the conductive copper layer.

Next is etching. This process exposes the copper and some parts unprotected by the etch resist film to an element that gets rid of the unprotected copper, which makes the protected copper traces and pads in place.

Another process is the drilling. This process drills off the holes for the protection of the board through some applications. During the process, another drilling would be used for the same purpose of protection.

The next step in the PCB manufacturing is platting. This process is the actual application of copper plating onto the traces, pads and drilled through the holes that were made during the drilling process.

Next to that is masking. This process is the application of protective masking materials over the bare traces so that the whole PCB is coated and protected.

The last phase is the finishing. This process is the coating of pad areas around the thin layer of the solder to organize the board for the reflow soldering process.

Best Way to Find PCB Manufacturing Companies

The fastest way to search for PCB manufacturers is through the Internet. You can see dozens of companies that offer manufacturing of PCB. You can also get more details and information about a certain PCB provider so you will have high chances of finding reputable service providers.
