- RF shielded test enclosures, also called RF shielded test boxes, are used for testing of RF and microwave devices in an isolated test environment, which lacks interference of other devices as well as the external environment
- These test boxes are used in isolation from unintended electromagnetic interference in noisy surroundings. In order to check whether a device is functioning up to the mark in an isolated environment, these boxes are used by equipment manufacturers.
- Shielding is typically used in enclosures in order to isolate the electric devices inside them from external influences and for cables in order to isolate wires from the environment through which the cable runs
- Previously, the above-mentioned process was being performed in anechoic chambers. These chambers are large rooms, which are highly expensive. Shielded test chambers are compact boxes, which can be placed on a table in a test lab.

Key Drivers and Restraints of Global RF Shielded Test Enclosures Market
- New advancements in materials used for manufacture of RF shielded test enclosures, such as shield metalwork (or metallization), are offering a low-inductance RF ground reference. This a key factor driving the global RF shielded test enclosures market.
- Manufacturers are designing RF shielded test enclosures with compact size, which are large enough for system tests. The material used in these RF shielded test enclosures is rugged welded aluminum.
- Manufacturers are focusing on making these boxes with high effectiveness in terms of RF shielding so that operations can be smooth and trouble free throughout their life. Moreover, new and advanced RF shielded test enclosures are available with a wide variety of connector options.
- During the production process, wireless devices often need to be activated without any external interference for quality and process control checks. In order to insure that radio frequency signals are solely from the individual unit being tested, the RF isolation is required on assembly lines or in test areas.
Semiconductor & Electronics Segment to Lead Global RF Shielded Test Enclosures Market
- Use of electronic devices is increasing, so is the exposure to a wide range of frequencies. Radiation and immunity need to be taken into account in early stages of the development of new products.
- Usage of RF shielded test enclosures is the most rapid method to prevent electromagnetic interference and comply with legal requirements issued by bodies such as CE or FCC. Hence, these enclosures are required in the semiconductor & electronics industry.
- RF shielded test enclosures can be used for appliances with high radiation or sensitivity levels or for products wherein these levels are not known in advance, for example, modular enclosures. Shielding are used while dealing with sensitive measurements that can be affected by ambient fields.
- Thus, the RF shielded test enclosures market is consistently expanding, especially in China, South Korea, and parts of North America, where manufacturers of semiconductor and electronics products are numerous

Galvanic Corrosion and Openings in RF Shielded Test Enclosures to Hamper Market
- Manufacturers use the conductive layer on the outside of the gasket, which is in the same galvanic range as that of the construction material in order to prevent galvanic corrosion, which weakens the electric conduction within the structure. This decreases the shielding performance.
- It is important to prevent gaps in the enclosure, especially at frequencies above 5 kHz. High frequencies ranging between 100 MHz and 40 GHz are very sensitive if there is even a small gap in the enclosure.
- The higher the frequency, the more attention is to be paid to prevent holes and gaps in the shield. These factors are projected to hinder the global RF shielded test enclosures market during the forecast period.
