circuit board; substrate
Refers to a board on which electronic components are mounted, such as a printed circuit board (PCB) or a substrate in electronics.
We mounted the IC chip on the circuit board.
Many electronic components are mounted on this circuit board.
We designed a new board and made a prototype.
We designed a circuit board for the new product.
This factory mass-produces circuit boards.
回路基板 emphasizes the circuit itself printed on the board, whereas 基板 can refer to the substrate material more generally, even before circuitry is added.
基盤 (きばん) means 'foundation' or 'basis' in an abstract sense, while 基板 (きばん) is the concrete electronic circuit board; they share pronunciation but differ in kanji and meaning.
Used because 基板 (circuit boards) are thin, flat objects, e.g. 基板2枚.
Standard kanji spelling for 'circuit board' or 'substrate'.
Irregular kanji usage sometimes seen, but 基板 is the correct and preferred form.
Compound of 基 (base, foundation) and 板 (board, plate). The spelling 基盤 is an irregular usage, likely influenced by the homophonous 基盤 (foundation, basis).
