3 Categories of Electrostatic Discharge (ESD) Films That You Should Know About

Electrostatic discharge (ESD) films offer effective protection against electrostatic discharge, a phenomenon wherein static electricity generates a flow of electric current between two objects of varying electric potentials. The very fact that electrostatic discharge has been one of the major restricting factors faced by semiconductor manufacturing industry, makes ESD films a valuable product in today&#;s world. ESD films are classified in three categories based on their working principle- conductive, dissipative, and anti-static.

The electronics and semiconductor manufacturing industry faces numerous challenges which create hindrances in realizing its full potential. Shortage in raw materials for manufacturing semiconductor chips is one of the important restricting factors of this industry. Similarly, a phenomenon known as electrostatic discharge is an important challenge faced by the semiconductor manufacturing industry.

Electrostatic discharge can be defined as a sudden flow of electric charge from a high voltage potential to low voltage potential. The electric charge or current develops as a result of the buildup of static electricity due to accumulation of electrically charged electrons over a small area. Not just in electronic circuits, electrostatic discharge is a common phenomenon and occurs in the atmosphere too, resulting in lightning strikes. However, the electrostatic discharge that takes place in semiconductors is rather subtle and causes sparking in these circuits. Nonetheless, this sparking can render the circuits useless.

In order to counter the problem of electrostatic discharge, electrostatic discharge packaging materials have been devised. Electrostatic discharge packaging materials essentially protect the electronic circuits by restricting the flow of electric current between them. Electrostatic packaging materials come in different configurations such as electrostatic discharge (ESD) films, electrostatic discharge (ESD) stick magazines, electrostatic discharge (ESD) matric trays, etc. Of these configurations, electrostatic discharge (ESD) films are one of the most opted ESD packaging materials.

Different Categories of Electrostatic Discharge (ESD) Films Available in the Market

Apart from the electronics and semiconductor manufacturing industry, the huge demand for electrostatic discharge (ESD) films from different sectors like food processing industry, medical sector, and aerospace industry has resulted in a massive boost in the electrostatic discharge (ESD) films market in the last few years. As a result, different types of ESD films are being marketed today to suit the needs of different industries and sectors. Basically, any electrostatic discharge (ESD) packaging material belongs to either of the three categories based on its properties- conductive, dissipative, or anti-static. The working of ESD films depend on the categories they belong, even though their main function remains the same.

1. Conductive Electrostatic Discharge (ESD) Films

Conductive ESD films have low electrical resistance, meaning electrons, and hence the electric current, can easily pass through these films. Hence, when an electronic circuit is packaged using a conductive ESD film, instead of passing the electric current onto other circuit, the current passes through the films, thereby avoiding electronic discharge between the two circuits. Since the conduction of electric charge through these films is pretty fast, conductive ESD films can offer a discharge even to the strongest electric currents.

2. Dissipative Electrostatic Discharge (ESD) Films

Dissipative ESD materials are different from conductive materials as they slow down the flow of electrons to the ground. Thus, the flow of the electric charge is in a controlled manner than that in conductive materials. A unique feature of dissipative ESD films is that they offer protection to the electronic components from the atmospheric moisture. In fact, these films soak in the moisture from the air to form a layer of water molecules over the surface of the film which, in turn, makes it difficult to generate and pass electric current.

3. Anti-Static Electrostatic Discharge (ESD) Films

Anti-static electrostatic discharge films mainly focus on inhibiting triboelectric charging. Triboelectric charging is a type of static electricity wherein the contact electrification occurs upon separation of two electrically charged objects. Anti-static ESD films are extensively used in the aerospace industry as a protective material to cover and protect sensitive spacecraft components and equipment.

Recent Trends in Electrostatic Discharge (ESD) Films Market

In the last few years, some major players of this industry have claimed to have invented extra-conductive ESD material which is suitable for discharging very strong electric currents. Also, a new kind of ESD film is launched recently which offers protection from corrosion and UV rays. This ESD film is said to be based on a technology called as Vapor Phase Corrosion Inhibitor Technology, which protects the semiconductors and metals from rust, oxidation, and tarnish. Moreover, the company, Cortec Corporation, which is involved in the research of this ESD film claims that the film is non-toxic and recyclable. Thus, the electrostatic discharge (ESD) market is undergoing a massive upheaval due to stunning innovations and technological advancements. This will surely help both the ESD films market as well as the electronics manufacturing market in the long run.

ESD Pet film refers to a type of film made from polyethylene terephthalate (PET) that has been treated to have electrostatic discharge (ESD) properties. PET is a commonly used material known for its excellent clarity, dimensional stability, and strength.

ESD Pet film is specifically designed to control or dissipate static electricity, which can be detrimental to sensitive electronic components and devices. Static electricity can build up on surfaces, and if discharged in an uncontrolled manner, it can cause damage to electronic circuits, data loss, or even fires in certain situations.

ESD Pet film is typically coated or treated with special additives that enhance its electrical conductivity, allowing static charges to be quickly and safely dissipated. The film can be used as a protective layer or packaging material for electronic components, integrated circuits, printed circuit boards (PCBs), displays, and other sensitive devices. It helps to prevent static electricity from accumulating on the surface and provides a controlled path for the discharge of any built-up charges.

The ESD properties of the PET film are important in industries such as electronics manufacturing, where static control is crucial to ensure the reliability and functionality of sensitive electronic equipment. The film is available in various thicknesses and can be customized to meet specific ESD requirements.

Overall, ESD Pet film offers a combination of PET&#;s physical properties and the ability to dissipate static charges, making it an ideal material for protecting electronic components from electrostatic discharge.
