A printed circuit board by itself is a very simple piece of technology: it is a board on which a circuit is laid out. However, oftentimes when people refer to a PCB they are also referring to the components that form the beginning of the circuit. The circuit is essential to the entire piece of equipment the board is in, which is why people include it when talking about the PCB. These include the necessary power supply, along with various other parts. This article will explain the different components in a PCB and the circuit that goes with it.

A printed circuit board first has a side of copper trace on it, which carries electricity around the board to complete the circuit. A PCB can have many different layers, but there will always be at least one side with copper tracing on it, bringing charge to the necessary places. The layers are important, however, since more complex electronics require more and more layers. The layers are made largely out of copper with various other metals around the edges, though it is what’s on the board that’s important. As the charge travels through the tracing, it also passes through the components of the PCB. The charge is diminished depending on what resistors it encounters, and when it is transferred through a transistor the charge grows to whatever it needs to be in order to power the electronics. There are also parts that will let charges through or block them depending on their positions, such as diodes and switches.
The circuits laid out on the boards are still not very impressive, however. The real value of PCBs come from the fact that they make up so many forms of technology. If you are a PCB manufacturer and you are reading this article wondering about what kinds of uses you can market your boards with, just consider the many ways they are applied around the world. There are hardly any electronic devices that don’t contain circuit boards, in fact: PCBs are in microwaves, every kind of computer, and practically anything that can be programmed a certain way: which includes calculators and even most modern cars. As technology advances, it is sure that we will still rely on PCBs to be the backbone of the latest electronics- meaning that there will be a huge demand for printed circuit boards in the foreseeable future.

But how exactly does a PCB allow these complex electronics to work, you ask? Well, this is the simplest aspect of the PCB: by itself, it can’t really do anything except power the LEDs and other components that are on the board. But when it is connected to other parts in a larger system, it can deliver electric charge to those parts and support the whole system physically due to the sturdiness of the boards. It delivers electricity through the copper tracing: really the key to the entire board and by extension, all the electronics the boards appear in.

Electronic Manufacturing Services Industry Trends

The Electronic Manufacturing Services Industry only truly became a profitable business around the 1970s, when Solectron, a company that would provide custom parts for other companies, including printed circuit boards and other necessary parts for high-tech products. This allowed companies to focus on product design rather than spending additional money and resources on building and shipping their own parts. From then on, electronic manufacturing continued to be a profitable business up until the present. This article will focus on the specific eras and trend of the EMS industry, starting with back in the 1970s.
In 1977, printed circuit boards were heavily in demand, yet expensive and inefficient to make if a company did not have dedicated facilities for producing then. Due to this, many independent manufacturing companies popped up, beginning the trend of electronic manufacturing services. The industry would remain pretty much where it was, with some minor improvements, but nothing too big changed until the 1990s.
Near the beginning of the 90s, printed circuit boards were able to be manufactured with more efficiency than ever before, due to SMT or Surface Mount Technology, which let the various components of PCBs to be assembled by mounting the parts onto the PCB. However, the ease of constructing new boards meant that companies sometimes did not need to outsource their manufacturing, which led to a decline of the market. In an effort to maintain relevance, many electronic manufacturers would try to take a larger share of the market, and maintain a monopoly on EMS by buying smaller companies.

Today, the Electronic Manufacturing Services Industry is still a profitable business venture. Top manufacturers include FIH Mobile and Foxconn, who has worked on contracts from Apple among many other top technology creators. As the demand for PCBs and other electronic components grow, the industry of EMS will also thrive, bringing a new trend of electronic manufacturing.
Because the EMS industry has only been around for about 50 years, there have not been many extreme changes in the trends. However, the technology behind EMS will continue to grow, which may lead to either the industry becoming more widespread as more specialist companies arise, or the industry declining as organizations who relied on third party manufacturers before now have the capabilities to put out their own parts for their products.
Whatever happens to the Electronic Manufacturing Services Industry, it is important to look back at the history of the market, which has led the many long-time PCB producers through many different phases: from busy and profitable periods of time to frantic years of buying and selling in an effort to remain on top of the market. The future of the industry may lead to a relapse into one of those phases, it may remain where it is now, or it may bring around an entirely new phase. Whatever new steps the industry takes, it it sure to rely on innovations in technology manufacturing, and the steps that first and third party manufacturers take to ensure efficiency and quality in their products.
