one. Printed circuits provide the following functions in electronic devices:Provides mechanical support for fixing and assembling various electronic components such as integrated circuits. Wiring and electrical or electrical insulation between various electronic components such as integrated circuits are realized. Provide the required electrical characteristics, such as characteristic impedance. Provides solder mask patterns for automatic soldering, providing identification characters and graphics for component insertion, inspection, and repair.
two. Some basic terms related to printed boards are as follows: On an insulating substrate, a conductive pattern formed by printing wires, printed elements, or a combination thereof, according to a predetermined design, is called a printed circuit. On an insulating substrate, a conductive pattern that provides electrical connections between elements and devices is called a printed circuit. It does not include printed components. Printed circuit or printed circuit board called printed circuit board or printed circuit board, also known as printed board.
Printed boards can be divided into two broad categories depending on whether the substrate used is rigid or flexible: rigid printed boards and flexible printed boards.
This year has seen a rigid, flexible printed board. According to the number of conductor pattern layers can be divided into single-sided, double-sided and multi-layer printed boards. The printed circuit board, in which the entire outer surface of the conductor pattern is on the same plane as the surface of the substrate, is called a planar printed board.
