The function of the automotive relay is to control the magnitude and on-off of the current. The following is a detailed introduction about automotive relays:
1. Automobile relay is an automatic control device whose output will change in leaps and bounds when the input (electricity, magnetism, sound, light, heat) reaches a certain value. High vibration. Automotive relays consist of a magnetic circuit system, a contact system and a recovery mechanism.
2. No-clean flux should be used for welding as much as possible, and overall cleaning of the relay should be avoided. Prevent cleaning agent from entering the relay and causing failure. Do not use ultrasonic cleaning to avoid contact cold welding, enameled wire breakage and other structural damage caused by ultrasonic energy. After cleaning and drying, the relay should be ventilated immediately to allow the relay to cool down to room temperature. Sometimes in order to ensure the moisture resistance and high insulation of the circuit board, the circuit board must be coated with a preservative. Softer glue that does not contain silicon should be used. The glue coating process should avoid the negative pressure of the relay and the inhalation of the preservative.
