Is Vci Anti-Corrosion Film Effective for Protecting Chips During Storage?

Many people mistakenly believe that simply placing chips in an anti-static bag is sufficient protection. However, reality is often not that simple.

After packaging, chips still contain numerous metal structures, such as pins, pads, bonding wires, and shielding layers. These parts are highly sensitive to humidity, oxygen, and sulfides.  If the environment is not controlled, oxidation, corrosion, and even electrical performance drift can occur.

The risks are significantly amplified in the following scenarios:

• Long-term warehouse storage

• International sea or air freight

• High-temperature and high-humidity regions such as Southeast Asia

• Supply chain nodes involving multiple unpacking and transshipments

During its collaboration with numerous electronics and semiconductor clients, CVCI has found that many seemingly problem-free chips only reveal abnormalities during client assembly or testing phases, and the root cause is often micro-corrosion during storage and transportation.

What are the actual benefits of using VCI anti-corrosion film for chip storage?

Unlike traditional anti-rust oils and liquids, VCI anti rust film does not need to be directly applied to the chip surface. Instead, it protects the metal parts surrounding the chip through volatile corrosion inhibitor molecules released into the packaging space. This method is very friendly to chips.

In CVCI's actual projects, VCI anti-corrosion film is usually used in combination with anti-static packaging and desiccants, for chip trays, reels, inner packaging, or secondary sealing.

This combination has been proven to effectively reduce problems such as pin oxidation and pad discoloration, and is especially suitable for chip products exported to the Southeast Asian market.

The main working principle of VCI anti-corrosion film is actually not complicated.

Many people's misconceptions about VCI anti rust film stem from not understanding how it works.

The core of VCI anti rust film is not to isolate air, but to create a chemical environment that inhibits corrosion reactions in a closed or semi-closed space through volatile corrosion inhibitors (VCI) released from the material.

These VCI molecules actively adsorb onto the metal surface, blocking the reaction path between moisture, oxygen, and the metal, thereby delaying or preventing corrosion.

Importantly, this process is molecular-level protection; it does not form a thick film, does not cover conductive areas, and does not affect the electrical performance of the chip. During the development of VCI anti rust films, CVCI pays special attention to release rate, shelf life, and compatibility with electronic materials, ensuring that the anti-corrosion protection is just right, without over-intervention.

Will VCI anti-corrosion film for chips affect electrical performance or cleanliness?

This is one of the most important questions for semiconductor customers.

Based on numerous real-world cases, as long as the VCI anti-corrosion film developed specifically for the electronics industry is used and applied correctly, it will generally not negatively affect the electrical performance of the chips.

VCI anti rust film is non-conductive, leaves no oily residue, and does not form a visible contamination layer on the chip surface.

When serving customers, CVCI usually provides more suitable anti-corrosion film specifications based on chip type, packaging method, and cleanliness requirements. This is why our collaborations with electronics and semiconductor customers are often long-term and stable.

From an export application perspective, is VCI anti rust film reliable in the chip field?

If the principle is reassuring, then real-world export applications are the most direct proof.

CVCI's VCI anti rust films have been exported to many countries and regions, with particularly mature applications in the Southeast Asian market. Facing the challenges of high temperature, high humidity, and long-distance transportation, the performance of VCI anti-corrosion film in chip storage and packaging has been repeatedly verified by many customers.

Many customers initially only tried it out, but after actually reducing quality complaints and rework rates, they gradually incorporated VCI anti rust film into their standard packaging solutions.
