1. The tin surface of the tin pot should be horizontal. When the tin surface is not normal, production must be stopped and the biotechnology must be notified.
2. When the automatic soldering machine equipment has abnormal conditions such as power failure, stop heating, stop operation, temperature uncontrollable or smoke, and burning odor, the production must be stopped, the valve and power supply should be shut off, and the maintenance and team leader should be notified in time.
3. When the temperature of the solder pot rises above 40 °C (shown in the PV column), it is strictly forbidden to touch the tin furnace to prevent burns. It is strictly forbidden to throw foreign matter into the pot to prevent splashing of high temperature tin liquid.
4. When there are bad phenomena such as welding, welding, leakage welding and abnormal appearance, the product must be reworked (up to only one rework). In the case of virtual soldering or soldering, properly deepen the soldering depth or increase the temperature appropriately (within the scope permitted by the process documentation), and check if the soldering flux of the automatic soldering machine is too small; when soldering occurs, reduce the soldering depth appropriately, and Check the quality of the foot wrapping; when the skeleton is burned, reduce the solder depth or lower the temperature (within the scope of the process document). When the defect occurs repeatedly and the debugging is invalid, the production must be stopped and the biotechnology and team leader must be notified.
