The spelling of the word "circuit cards" can be explained using the International Phonetic Alphabet (IPA). The first syllable is pronounced /ˈsɜːrkət/, with stress on the first syllable and the "c" pronounced as an "s" sound. The second word, "cards," is pronounced /kɑːrdz/, with stress on the first syllable and the "a" pronounced as an "ah" sound. Together, the word is pronounced as /ˈsɜːrkət kɑːrdz/. This term refers to electronic circuitry on a card-shaped board used in computers and other devices.
Circuit cards, also commonly referred to as circuit boards, are essential components in electronic devices and systems. They are thin, flat boards made of non-conductive materials, typically laminates like fiberglass or epoxy, with one or both sides coated in a conductive material, usually copper. These cards serve as platforms for various electronic components and provide the necessary paths for electrical current to flow and be distributed throughout a system.
Circuit cards are designed with intricate patterns of conductive traces, also known as copper traces or tracks, which connect different electrical components, including integrated circuits (ICs), resistors, capacitors, and transistors. The copper traces form a network of interconnections that facilitate the transfer of signals and power between these components, enabling them to function together.
These cards often contain multiple layers of conductive traces, separated by insulating layers, which increases their complexity and functionality. They may also feature plated through holes (PTHs), which are small drilled holes that connect different layers of the board to create vertical connections. This allows for three-dimensional routing of traces, accommodating complex circuit designs in a compact space.
Circuit cards are manufactured using advanced techniques such as computer-aided design (CAD) and printed circuit board (PCB) fabrication processes. They are vital in a wide range of electronic devices, including computers, smartphones, televisions, medical equipment, and industrial machinery. Their compact design, robustness, and ability to provide stable electrical connections make circuit cards indispensable in the modern world of electronics.
The word "circuit cards" is a combination of two terms: "circuit" and "cards".
1. Circuit: The term "circuit" can be traced back to the Latin word "circuitus", which means "a going around". In the context of technology, it refers to an electric circuit, which is a path for an electric current to flow.
2. Cards: The term "cards" is derived from the Old French word "carte" and the Latin word "charta", both meaning "paper, card, or map". In the context of technology, "cards" refers to the physical card-like components used to hold and connect electronic components.
The combination of "circuit" and "cards" likely stems from the use of electronic circuits mounted on card-like structures, which eventually became known as "circuit cards".
