Double sided Circuit Board



Product process description:

Production process: lead-free process

Process flow: SMT+DIP

Material testing requirements: Test individual materials in advance, such as 呤器.

IC burning: the need for external programming of chips in advance

Special sensitive device processing: storage and transportation methods for temperature and humidity sensitive components.

Welding method:

1. The temperature of the soldering iron is controlled between 330 °C and 350 °C.

2: The connector cannot be welded, and the left and right are skewed and raised.

3: The tin point should be full and bright, and there should be no sharpening, less tin, bubble holes and too much tin.

4. U2 bit module needs to form welding pin header in advance, short foot is inserted in the module, pay attention to SD card seat facing up

The cleaning method of the circuit board: the washing water can not corrode the internal contacts of the connector. When forming the U2 module, the cleaning agent should not be immersed in the inside of the card seat to avoid necrosis and poor contact.
