At the heart and soul of every electronic device we interact with on our daily routine lies a circuit board. Circuit boards are essentially the brain of electronic components with several circuits, tracks, and relays to send electronic signals where they need to go. Circuit boards have been in use since the early 1900s and have gotten smaller and more advanced as time moves forward. To understand how a circuit board is assembled is essential to understanding how they work; while there are certainly a lot of complicated components including transistors, diodes, resistors, inductors, transformers, and capacitors, understanding the essentials behind a printed circuit board is ultimately a less daunting task in all reality.


The Skeleton of a Printed Circuit Board

The actual board of the printed circuit board is essential to the mounting of components. This board is typically produced out of a glass epoxy that serves as an insulating layer. On top of this epoxy is a thin layer of copper foil that has been laminated on one or both of its sides. Upon this copper layer, circuitry connections are etched in order to produce the tracks that allow printed circuit boards to function — more complex circuits require several layers of these materials. Prototype PCB manufacturing companies typically use one of three methods to produce the legend which contains component designators and other indicators to aid in assembly, testing, and servicing of the PCBs: silk screen printing; liquid photo imaging; and ink jet printing are all used to print legends on the prototype circuit boards. One final distinction regarding the board itself is the very way that components are mounted to the piece. Through-hole mounting has been used for decades and requires the components to be physically mounted through pre-punched holes on the circuit board. Since the 1980s however, many prototype PCB manufacturing companies are utilizing surface mounting technology with smaller components to provide the same function without the need for holes.


Circuit Assembly

With the rise of surface mounting for PCBs comes the need to solder pieces onto the board. There are a number of differ soldering techniques used: high volume PCB production is usually done with SMT placement machines or bulk wave soldering; skilled technicians however are able to solder very tiny pieces by hand, sometimes pieces even as small as 0.02 inch by 0.01 inch. The actual assembly varies based upon the needs of certain circuits. Integrated circuits are sets of electronic circuits on one small flat piece of a semiconductive material which is typically silicon — these are the most frequently used circuits for basic electronic work. Another type of circuit assembly is the hybrid circuit which includes a number of components such as semiconductors and passive components mounted together as a single unit — these are typically reserved for more complicated circuit assemblies due to their bulky size.


Prototype PCB Manufacturing Companies

Circuit boards help to bring the inventions of our dreams into realty. By understanding the unique needs of a particular electronic, experienced prototype PCB manufacturing companies are able to create a customized printed circuit board that fits one’s own unique needs. Many printed circuit board manufacturing companies are able to offer both surface mounted printed circuit boards as well as through-hole printed circuit boards. Many of these printed circuit board manufacturing companies are able to offer single layer and multi-layer circuit boards to help fulfill a variety of circuitry needs. For those working on deadlines, many also offer quick turn printed circuit boards that are typically shipped out within 24 hours. Printed circuit board manufacturing companies are crucial for prototyping as well as general production: many printed circuit board manufacturing teams have specialists that are able to work one-on-one with businesses through the entire development process to ensure that each circuit board is tailored to the individual’s needs. For those with the ideas to power their business, allow experienced printed circuit board manufacturing companies to help make the connections that will allow your idea to soar.
