Infrared Lamp Board Is Monitoring Camera

The infrared lamp board has a key role in monitoring the camera. Below, the editor of the infrared lamp board will explain the process of the infrared lamp board. 1. Preparation of raw materials, engineer design plan PCB, and then submit to PCB manufacturers printed circuit board. Then the purchase of raw materials, including resistance, diode, triode, etc. 2. Perform HSMT or SMT, HSMT refers to handmade patch, SMT refers. 3. The selection of infrared lights should be selected according to the needs of the plan. 4. Over -lead furnace, also known as reflux welding. It uses the principle of contraction when the hot -melt tin encounters the gap of copper band. Before the current flow welding, there is no need to insert an infrared light or light -sensitive resistance site. The power supply and inserted position should be sticking with high temperature adhesive paper. 5. The next is DIP, that is, the plug -in. When inserting the selected LED infrared lights on the PCB board, the positive and negative pole of the LED infrared lamp must be distinguished (you can distinguish the positive and negative poles through the PN in the PN in the LED infrared lamp, the larger one is the negative electrode, and the small one is the positive pole). 6. Over -welded welding, put a board on both ends of the machine, and one person to collect the board. Employees must bring protective gloves to prevent scald during operation. Placing an ionic fan at the outlet. anti-static. 7. The cutting of the DIP plug -in is divided into hand -cut and foot cutting feet. At this time, you must pay attention to the position of the cut. Do not be too long, so that it is easy to fold your feet during transportation and cause short circuits, and you should not be too short. Considering the protection of electronic devices such as triode pipes. In the process of cutting their feet, employees must bring goggles to prevent debris splashes for eyes. 8. Visual inspection, mainly check whether the process process is correct, whether the electronic devices are inserted or wrong, whether the tin points are qualified, and the tin points are unqualified to replenish welding. 9. Put on power supply and inserted foot. 10. Install the light -sensitive resistance, you must first put the plastic cover of the light resistance, and then install the infrared lamp plate. 11. Second inspection, link power supply, check whether the lights are bright, whether the light -sensitive resistance plays a role, picked out the bad products. 12. Washing boards are divided into artificial laundry and machine washing. Because there are many residual lead slag on the infrared lamp plate, etc. The proportion of laundry water should be appropriate, and the time of soaking must be controlled. The speed of the laundering machine must be controlled, otherwise it will easily hurt the circuit board. After the machine washed Washing it will be washed with a toothbrush and washed on handwashing water. 13. Drying, pay attention to the temperature of the dryer. If the temperature is too high, the tin lead will fall; too low, the effect of not drying. 14. Filter filter. 15. After the QC test, it is mainly whether TEST can work normally. 16. Aging (the conventional is 72 hours). 17. Inspection, under the aging of infrared lamps, inspections must be inspected every two hours, and the inspection record is done. 18. After the aging is over, check again, the infrared lamp board process process is completed.
