A printed circuit board (PCB) mechanically connects and electronically interfaces electrical components with conductive pads, transducers and other structural features etched into one or more layer layers of standard non-metallic copper (or other conductive material) laminated on and/or between two or more layer(s) of standard non-metallic core material. The term "PCB" is now generally used to refer to a stack of printed circuit boards. The layers are typically printed in a variety of colors, using various printing methods, with the final goal of providing the best possible result in terms of the most legible and elegant design. Certain key characteristics of printed circuit boards have been developed over the years - including high reliability, durability, flexibility, and ease of use - that have made them a top choice for many industries, including the electronics and printed circuit manufacturing industries.
Of course, one of the primary factors in determining whether printed circuit boards are chosen is the overall cost of purchasing, as well as its suitability for a given application. It's not uncommon for large companies to purchase thousands of printed circuit boards to meet their needs for a wide range of applications, from data storage to military applications to telecommunications. But even smaller companies can benefit, as recent improvements in the type of pcb materials available to enable the manufacturing of many new varieties of PCB at a fraction of the cost of older printed circuit boards. Some of the newer PCB materials include polyester fiber boards, which exhibit greater heat resistance and offer increased durability; dipole multi-layer materials that are even more cost-effective than multi-layered materials; and thermally broken core materials, which are a combination of both polyester fiberboards and thermally broken core materials that offer even greater reliability. All of these materials have been developed by well-known, established PC manufacturing companies such as Honeywell, Dell, and HP.
Although the primary use of printed circuit boards today is to support computer hardware, they're also found in medical imaging and industrial machinery. Thermoelectric devices used in medical imaging machines utilize PCBs, as do electronics instruments that rely on delicate but conductive components called conductors. And, of course, computer networking systems make use of PCBs. The potential applications of printed circuit boards don't end there. Virtually any piece of machinery or equipment that has an analog input and an analog output - from watches to garage door openers to radar detectors - makes use of PCBs.
As for the substrate on which printed circuit boards are printed, it has a significant impact on both the efficiency and the effectiveness of the device. Cheap substrates have a pronounced influence on both these factors, as poor substrates can be inefficient when printed with certain types of PCB. Good, sturdy substrates, however, have a definite advantage when it comes to resisting indentation, heat damage, and abrasion. This is why many of the most highly-regarded printed circuit boards use polyester or other high-quality resins as their substrate. In addition, these substances are generally available at affordable prices, which is another factor that's important for many companies.
Copper has long been used as a substrate, and is still a popular choice for printed circuit boards. Like many metals, copper has a unique electrical charge, which means it has the potential to form conductors with different electrical fields if subjected to an alternating current of low voltage. Additionally, copper is thermally stable, which means that it does not change temperature even when left in an open area for a long time. And, of course, copper has been used for millennia as a printing medium because of its excellent print quality. It is a very durable material with a high print yield percentage.
In order to make use of all of these features of printed circuit boards, you need to purchase your components in large quantities, since only a single piece of equipment can interface with a large number of components. Luckily, there are many manufacturers that specialize in providing printed circuit boards for a wide variety of applications. So, whether you need to connect a PIC, microcontroller, or other device to an LED, ribbon, or LED, you will be able to find the right components in the right quantity.
