What should be paid attention to when installing domestic components?
1. Pay attention to the direction in which the lead is bent
There are pins on the domestic components, which are the wiring between the internal circuit of the component and the peripheral circuit. If the pins are not handled properly during installation, the components will be damaged. Therefore, when installing domestic components, attention should be paid to keeping the bending direction of the pins consistent with the copper foil routing direction.
2. pay attention to the packaging of the shell
When installing domestic components, it is necessary to pay attention to the polarity of the diode, and also to the package of the component, especially for the package with a glass shell, because the glass shell is easy to be damaged, when the lead is bent It is also easy to burst. Therefore, when installing, you should pay attention to winding the lead wire one or two times before installing. For high-current diodes, some components will use the lead body as a heat sink, so it needs to be based on the diode specifications. It is required to determine the length of the lead, and it is not appropriate to cover the lead with an insulating sleeve.
3, pay attention to distinguish between positive and negative ends
The motors and electrolytic capacitors in the components have positive and negative terminals. In order to avoid confusion between the positive and negative terminals, you must pay attention to the difference when installing domestic components. Normally, you can add straps to the positive and negative terminals. There are colored sleeves to distinguish.
In order to ensure the installation quality of the components, in addition to using domestic components with stable quality, it should also be noted that the bending direction of the pins on the domestic components is the same as the copper foil routing direction, and attention should be paid to the use of different colors. The casing is used to distinguish the positive and negative terminals of the electrode and the electrolytic capacitor, so as not to confuse the positive and negative terminals.
