In 2006, the City of San Diego in California was rated as the fifth ( PCB Fabrication ) best place to live by Money Magazine. In the same year, Forbes Magazine ranked it as the fifth wealthiest state in the United States. One of the elements that made San Diego an economic forerunner that it is today is its expertise in numerous fields, one of which is in electronics manufacturing. More specifically, in PCB.
What is PCB?
A printed circuit board, or more commonly known ( Irvine Engineering Services ) by its abbreviation of PCB, is a thin board or plate where chips and other electronic components are connected. Threads of conductive material, usually copper, are used as wires between the components. This is also one of the reasons why PCBs are sometimes referred to as printed wiring board (PWB). Boards that already have electronic components connected are known as PCA or printed circuit board assembly.
Try to open up and check any broken electronic device that you can find in your home. If you find a board that’s probably colored green (that’s the PCB) and has electronic components ( San Diego PCB ) soldered onto it, that’s what you then call a printed circuit assembly (PCA).
History of the PCB
The PCB began as a simple component of a radio when an England-based Austrian Engineer named Paul Eisler made one in the mid-1930s. During the war in the 1940s, the ( Orange County PCB Fab ) United States borrowed the technology to start a widescale production of PCBs to make radios for use in World War II.
However, PCBs became a regular part of consumer electronics only in the mid-1950s. When consumer electronics began adopting this technology, the possibility of making electronic items in smaller packaging became more real.
PCB vs Point-to-Point Construction
Before the PCB became popular in the 1950s, point-to-point construction was the popular method used in connecting electronic circuits. Although still the choice in making prototypes composed of only a few or heavy components, point-to-point construction is no longer a preference in modern electronics.
PCBs have taken over point-to-point construction because in the latter process, screws or wire nuts were used to hold wires to the insulating board. The final product then becomes susceptible to short-term functionality since the screws and wire nuts can easily corrode and therefore damage the wires. Aside from that, the connections might come loose in the long run.
Through-Hole Construction and Surface Mount Technology
In the early days of the PCB, each electronic component had wire leads and drilling holes was necessary because it was the way through which each component lead can pass to connect and be soldered to the board. However, this drilling of holes was expensive.
Beginning in the 1980s, SMT or surface mount technology, paved the way for components to be mounted directly on the PCB, making resulting devices smaller in packaging because SMT components are typically smaller than components used in through-hole construction, Aside from this, the need to drill holes was reduced and therefore saving on costs.
PCBs have eliminated the need for wires and ( Orange County PCB Fab ) they have proven to be inexpensive, very reliable and less bulky than the way electronic devices were used to be made. In San Diego, quality PCBs are manufactured to meet the continuous demand for quality electronics. After all, a high quality PCB could mean a high quality electronic device.
