1 Select the appropriate wire type for your specific environment. It is usually necessary to consider moisture, heat, and corrosion to avoid insulation failure.
2 Regularly check and replace the line. Avoid the circuit being in disrepair for a long time, the insulation layer is old or damaged, and the core is bare.
3 When overcurrent or overvoltage occurs, it is necessary to detect the insulation strength of the line in time to prevent the insulation of the wire from being broken down.
4 Installation and repair personnel should work cautiously to prevent misconnection of the line or short circuit caused by human touch.
5 Install bare wires to ensure the height and wire spacing, to avoid accidentally touching the wires when handling metal objects, or to have metal objects falling off the line and short-circuiting between the wires.
6 Overhead lines must be in accordance with the requirements of the specification to prevent the wire spacing from being too small, the span is too large, the wires are slack, and the wires are collided; the distance between the overhead lines and the buildings and trees should meet the standard requirements, so as to avoid the wires from being driven by the wind. Building or tree contact.
7 Select a wire with a certain mechanical strength, avoid contact with the ground due to wire breakage, or break it on another wire.
8 Support insulators for high-voltage overhead lines should ensure sufficient withstand voltage, otherwise it will cause short circuit to ground.
9 When installing wires or attaching temporary lines, follow the rules. Private pulls and blindness often lead to short circuits. Temporary lines should be removed in time after use.
10 To take technical protection measures for electrical circuits, fuses and automatic air switches are usually used.
SMA means surface mount assembly. It is a new generation of electronic assembly technology, which compresses traditional electronic components into a device with a volume of only a few tenths.
Surface mounting is not a new concept, it is derived from earlier processes, such as flat mounting and mixed mounting.
For the assembly of electronic circuits, a point-to-point wiring method was initially adopted, and there was no substrate at all. The packaging of the first semiconductor device uses radial pins, which are inserted into the through holes of the monolithic circuit boards that have been used for the packaging of resistors and capacitors. Active components have been widely used in the past ten years.
