Product process description:
Component testing requirements: Test individual materials in advance, such as sewing machines.
IC pre-production burning: the need for external programming of the chip in advance.
Special sensitive devices: storage and transportation methods for temperature and humidity sensitive components.
Furnace experiment: All plastic molded patch materials are subjected to reflow soldering experiments.
Single-sided board chip soldering: U2 bit number is a common pad. When soldering the corresponding module, it is necessary to seal the pad steel mesh that is not needed before printing;
Product process information:
Board soldering method:
1: The temperature of the molten iron is controlled between 330 °C and 350 °C.
2: The welding temperature of the sensor, LED and buzzer is 330 °C, and the welding time is between 3 seconds and 5 seconds.
3: The connector cannot be welded, and the left and right are skewed and raised.
4: The tin point should be full and bright, and there should be no sharpening, less tin, bubble holes and too much tin.
Trial production report: The new product trial production report is sent to the salesman in the form of an electronic file.
