Anti-moisture and anti-static in the PCBA processing process is a critical link, directly affecting the performance and reliability of electronic products. In this paper, we will discuss the moisture-proof and anti-static measures in PCBA processing to ensure product quality and stability.
I. Moisture measures
1. Environmental control
PCBA processing workshop needs to maintain a relatively constant temperature and humidity, usually controlled at a temperature of 20-25 degrees Celsius, relative humidity 40% -60% of the range. This is conducive to preventing the PCB board and components to absorb moisture, reduce the corrosion and impact of moisture on electronic components.
2. Encapsulation and storage
PCB boards and components in the process need to take sealed packaging and storage measures to prevent moisture in the air. Commonly used encapsulation methods include vacuum packaging, desiccant encapsulation, etc., storage can use sealed bags or sealed boxes to maintain a dry state.
3. Moisture absorber and dehumidification equipment
The use of hygroscopic agents and dehumidification equipment in the PCBA processing plant to help reduce the humidity in the air, to prevent the impact of moisture on electronic products. Moisture absorbing agent can be placed in the storage box or processing workshop, dehumidification equipment can be regularly dehumidification of the workshop air.
II. Anti-static Measures
1. Grounding protection
During PCBA processing, all equipment and operators should be grounded and protected to ensure the release and orientation of static electricity. Ground connection should be firm and reliable, grounding resistance should meet the standard requirements to ensure that static electricity will not cause damage to electronic products.
2. Static elimination equipment
In the PCBA processing workshop should be configured to eliminate static electricity equipment, such as static electricity floor, static electricity eliminator, static electricity feet, etc.. These devices can effectively release the human body and equipment on the static electricity to the ground, reduce the impact of static electricity on electronic products.
3. Anti-static work clothes and tools
Operators should wear anti-static work clothes and use anti-static tools, such as anti-static gloves, anti-static vacuum cleaner, etc. during PCBA processing. These tools and equipment can reduce the generation and transmission of human static electricity, and protect electronic products from static electricity.
Features of NeoDen YY1 SMT machine
1. Brand new patented peeling gadget
It’s simple but functional, it’s easy to install and flexible to remove. Compared with the peelers of TM240A, it doesn’t need to collect wasted film. Compared with the peelers of 3V, it solve the issue of unstability and offset issue.
2. Dual vision system with built-in IC
Independent high-definition & high-speed dual vision recognition systems, as well as two cameras for real-time display the working status., the speed of processing components’ photos becomes more efficient and accurate.
3. User friendly touch screen
It comes with a high-definition capacitive touch screen, which can be adjusted up and down to meet the needs of different viewing angles and enhance the user experiences.
4. Auto nozzle changer
