What Is a Chip Tray?
A chip tray is a container for storing various chip-shaped components such as wafer chips, prisms, lenses, and crystals.
By placing semiconductor products, glass products, and other products for which dust adhesion or minute scratches can cause serious damage in a chip tray, it is possible to store and transport these products without compromising their functionality.
In addition, since a chip tray is compartmentalized inside, it can eliminate problems such as damage caused by collisions between contents during transportation, or mixing of contents that makes them indistinguishable from each other.
Uses of Chip Trays
Chip trays are used to store products in chip form in a compartmentalized case to protect them from dust and scratches.
Therefore, they are used as storage containers for wafer chips and semiconductor chips cut from silicon wafers used in semiconductors, as well as ball lenses and hemispherical lenses used in precision equipment.
Many of these products are manufactured in clean rooms, which are spaces under cleanliness control. Products are stored and transported in chip trays when they are carried outside the clean room for transportation to the next process or shipment.
Principle of Chip Trays
Most of the products stored in chip trays, such as wafer chips and glass lenses for precision instruments, are products that must not be scratched even slightly, so plastic, a relatively soft material that is resistant to fibers and other debris, is used for chip trays.
In addition, many of the components stored in chip trays are electrically sensitive products such as semiconductor products. Since these products may be damaged by static electricity accumulated in the trays, conductive polystyrene or antistatic ABS are used among plastics to prevent static electricity from accumulating.
Chip trays are manufactured in a variety of materials and colors, such as Bakelite or carbon fiber when heat resistance is required depending on the operating environment, or black when storing products that are sensitive to ultraviolet rays.
Since chip trays are often used in clean rooms, many chip tray products are pre-packed (manufactured in a clean room and shipped vacuum-packed).
