Indexing Plate/Disc
Sorting Plates/Discs, Indexing Plates/Discs and Guide Plates/Discs are key precision components in automation equipment, and are turntables with specific slots or configurations that are used to locate, segregate, transfer and sort materials. Loongceram’s indexing disk is a core component for banding machines.
Banding Machine/Taping Machine is a key equipment in the modern electronic component manufacturing process. Its function is to accurately encapsulate tiny electronic components (e.g. chips, capacitors, resistors, etc.) into carrier tapes for subsequent automated placement (SMT) processes. In this process, the Indexing Plate/Disc or Guide Plate, especially its core turntable part, plays a crucial role. It is responsible for high-speed, precise positioning and transfer of components, and its performance directly determines the efficiency, precision and reliability of the entire production line.

Sorting disks, indexing disks and guide disks made of ceramics have excellent abrasion resistance, chemical inertness and low coefficient of expansion, which significantly improves the operational efficiency, precision and reliability of the equipment. The flatness of the products can reach 0.003mm.
Step 1
Type of material
Ceramic sorting plates, indexing plates and guide plates are made of zirconia and modified zirconia, which can be selected according to the actual application conditions.
- Zirconia : Zirconia has very high fracture properties, overcoming the brittleness of ceramics, and is also self-lubricating, making it ideal for use in the production of sorting and indexing disks.
- Modified Zirconia (ATZ) : Adopts the ATZ composite material of zirconia reinforced with alumina. In addition to retaining the toughness and self-lubricating properties of the original zirconia substrate, the addition of alumina can also significantly improve the hardness and wear resistance of the material.
- Modified zirconia (blackened, conductive) : The zirconia matrix is blackened to prepare black zirconia, which improves optical recognizability. The zirconia matrix can also be modified to obtain conductive zirconia, to meet the demand for anti-static properties of the product.
Step 2
Product Features
- High hardness and abrasion resistance: withstands long-term, high-frequency impact and friction of test socket pins (Pogo Pins), resulting in extremely long service life and reduced maintenance and replacement costs.
- Excellent dimensional stability and low coefficient of thermal expansion: Insensitive to temperature changes, maintaining high geometric and positioning accuracy (micron level) during temperature fluctuations in the test environment or when the device itself heats up, which is critical to ensuring reliable and repeatable test contacts.
- High insulation resistance and excellent dielectric properties: Provide excellent electrical insulation to prevent signal crosstalk and ensure the purity and accuracy of test signals, especially in high-frequency, high-sensitivity testing.
- High rigidity and low deformation: not easy to bend and deform under mechanical stress and test pressure, maintaining the platform flatness, to ensure the consistency of contact at all test points.
- Good chemical stability and corrosion resistance: it can resist the influence of moisture and light chemicals in the environment.
- High surface finish: easy to clean, reducing the residual contaminants affecting the test.
Step 3
Core Functions and Positioning:
- Electronics and semiconductor industry : Ceramic sorting trays, indexing trays and guide trays can be used for precision sorting and taping of tiny electronic components such as chips, capacitors, chip components, etc., with service life and positioning accuracy far exceeding that of traditional metal products.
- Precision manufacturing industry : Ceramic sorting trays, indexing trays and guide trays can be used for the automatic sorting and feeding of small hardware, bearing needle rollers and other products.
- Pharmaceutical and Food Industry : Sorting, indexing and guiding trays made of ceramic can be used for counting and packaging of tablets, capsules and candies because of their non-polluting and easy-to-clean characteristics.
