PCB News - Anti-static during SMT chip processing

Anti-static during SMT chip processing
Our factory is located in China. For decades, Shenzhen has been known as the world's electronics R&D and manufacturing center. Our factory and website are approved by the Chinese government, so you can skip the middlemen and buy products on our website with confidence. Because we are a direct factory, this is the reason why 100% of our old customers continue to purchase on iPCB.
1. Regularly check the grounding system inside and outside the patch processing plant. The grounding system outside the workshop should be tested once a year, and the resistance requirement should be retested when the line is changed below 20.

Anti-static table mats, anti-static floor mats, and grounding systems should be tested every 6 months and should meet the requirements of SMT patch anti-static grounding.

When detecting the resistance between the machine and the ground wire, the resistance is required to be 1MΩ, and the inspection records should be made.

2. Measure the temperature and humidity in the workshop twice a day, and make effective records to ensure constant temperature and humidity in the production area.

3. Any operator of SMT patch processing must take anti-static measures before entering the workshop.

Operators who are in direct contact with the product must wear an anti-static wrist strap, and operators who wear an anti-static wrist strap are required to

Test each time before going to work in the first and next year to ensure good contact between the wrist strap and the human body. At the same time, relevant personnel are arranged for supervision and inspection every day, and employees are trained on anti-static knowledge in patch processing and on-site management.

4. When holding the product by hand during the production process, it can only be held at the edge of the product without electronic components; the product must be installed in an anti-static bag after production

Installing; During installation, it is required to take one product at a time, and it is not allowed to take more than one product at a time.

5. During the rework operation in the SMT factory, the product to be repaired must be placed in the anti-static device and then brought to the repair station.

6. The equipment and tools used in the whole production process should have anti-static ability.

7. After the SMT patch is processed, the products that pass the test and accept the qualified products are sprayed once with an ion spray gun and then packaged. iPCB is happy to be your business partner.
