The precious chip save environment

**Why Are Precious Chips Stored in a Constant Temperature and Humidity Environment?** In the electronics industry, it's well known that not all components are created equal. While standard electronic parts can be stored under general environmental conditions, high-value or specialized chips—such as security chips, medical chips, military-grade chips, biochips, and LED chips—require more controlled storage environments. These precious chips are often stored in constant temperature and humidity cabinets to ensure their long-term performance and reliability. The reason for this strict control lies in the sensitivity of these components. When exposed to ambient air, moisture from the environment can gradually penetrate through the packaging of the chips. If these chips are later soldered onto printed circuit boards (PCBs), the trapped moisture can expand rapidly due to the high heat of the soldering process. This expansion can cause internal damage such as delamination, cracking, or even "popcorn" failure—a phenomenon where the chip literally bursts due to internal pressure. To prevent such issues, it's essential to maintain a stable temperature and humidity level during storage. The ideal storage range for most standard chips is between 15°C to 30°C with a relative humidity of 30% to 60%. However, for high-end or sensitive chips, more precise control is necessary. This is where specialized storage cabinets come into play. Shenzhen Chuan’s constant temperature and humidity storage cabinets are designed specifically for the safe and effective storage of sensitive electronic components. Here are some of the key features that make them stand out: 1. **High-Precision Control**: These cabinets offer accurate temperature and humidity regulation, with a temperature range of 15–30°C and a humidity range of 30–60% RH. Custom settings are also available for more sensitive applications. 2. **Stable Environment**: The internal temperature fluctuation is kept within ±2°C, while humidity variation stays within ±5% RH. For film storage, even tighter tolerances like ±1°C and ±3% RH are possible. 3. **Robust Construction**: The cabinet is built with strong, sealed materials that provide insulation, dust resistance, anti-static properties, and protection against rust and magnetic interference. 4. **Safe Heating System**: Heaters are isolated to avoid any risk of damage to the contents or harm to users. 5. **Advanced Sensors**: Equipped with Honeywell sensors, the system automatically monitors and adjusts temperature and humidity levels in real time. 6. **User-Friendly Interface**: An LCD screen displays current temperature and humidity values clearly, making it easy to monitor and adjust settings. 7. **Simple Operation**: Setting up the cabinet is straightforward—just unlock, set, and confirm. No complicated procedures needed. 8. **Modular Design**: All internal components are modular, allowing for future upgrades or custom configurations to suit different industrial needs. 9. **Superior Dehumidification**: The use of 13X molecular sieve material ensures efficient and stable moisture absorption, even under varying conditions. 10. **Energy-Efficient Operation**: The system uses an intermittent operation mode, which activates only when the desired temperature and humidity levels are not met, reducing wear and extending the life of the components. 11. **Air-Cooled Refrigeration**: This ensures consistent and even temperature distribution throughout the cabinet, maintaining optimal storage conditions at all times. By using such advanced storage solutions, companies can protect their valuable chips from environmental damage, ensuring they remain in peak condition until they are ready for use. Whether you're dealing with standard ICs or cutting-edge specialty chips, proper storage is key to preserving quality, performance, and longevity.

DBC Substrate

DBC (Direct Bonded Copper) Substrate is a special process board where copper foil is bonded directly to the surface (single or double sided) of and AI203 OR AIN ceramic substrate at high temperatures and can be etched with various graphics. It has excellent electrical insulation performance, high thermal conductivity, excellent soft brazability, high adhesion strength and a large current-carrying capacity. DBC Substrate mainly used in the fields of rail transit, smart grid, new energy vehicles, industrial frequency conversion, household appliances, military power electronics, wind and photovoltaic power generation.

We custom high precision DBC Substrate with drawings provided by customers. The raw material we use for etched DBC substrate is Ceramic-based double-sided copper clad laminate. We are equipped with professional metal etching equipment and exposure development equipment. Our etching process can achieve double-sided etching of different graphics with 0.3 mm - 0.8mm thickness of copper clad laminate. Also, we can guarantee that our double-sided copper clad laminate substrate is neatly arranged, straight surface line, and have no burr, high product accuracy.

Its superiorities of DBC Substrate are as follow:

1. A ceramic substrate with a coefficient of thermal expansion close to that of a silicon chip, which saves the transition layer of Mo chips, saving labour, material and cost.

2. Excellent thermal conductivity, making the chip package very compact, thus greatly increasing the power density and improving the reliability of systems and devices.

3. A large number of high-voltage, high-power devices have high requirements for heat dissipation, and ceramic substrates have a better heat dissipation effect.

4. Ultra-thin (0.25mm) ceramic substrates can replace beo, without environmental toxicity problems.

5. Large current carrying capacity, 100A continuous current through 1mm wide 0.3mm thick copper body, temperature rise of about 17 ℃; 100A continuous current through 2mm wide 0.3mm thick copper body, temperature rise of only about 5 ℃.

6. High insulation withstand voltage, to ensure personal safety and equipment protection

7. New packaging and assembly methods can be realized, resulting in highly integrated products and reduced size

8. The ceramic substrate is highly resistant to vibration and wear, ensuring its long service life.
