There are many types of wafer tungsten-rhenium probe cards, and the following are some of the common types:
1. Single crystal tungsten-rhenium probe card: Single crystal tungsten-rhenium probe card is a probe card made of single crystal tungsten material, which has the advantages of high purity, high density and high strength. It is mainly used to test the electrical properties of semiconductor devices, such as resistance, capacitance, inductance, etc.
2. Polycrystalline tungsten-rhenium probe card: Polycrystalline tungsten-rhenium probe card is a probe card made of polycrystalline tungsten material, and its structure consists of multiple single crystal tungsten grains. Compared with single crystal tungsten-rhenium probe card, polycrystalline tungsten-rhenium probe card has a simpler manufacturing process and a cheaper price.
3. Composite material tungsten-rhenium probe card: Composite material tungsten-rhenium probe card is a probe card made of composite materials, such as tungsten/copper composite materials. This type of probe card has the advantages of high conductivity and high thermal stability, and is suitable for testing in harsh environments such as high temperature and high humidity.
4. Micro tungsten-rhenium probe card: Micro tungsten-rhenium probe card is a miniaturized probe card with the advantages of small size, light weight and easy to carry. It is suitable for small-scale production and testing, such as small batch testing in laboratories and production lines.
5. Customized tungsten-rhenium probe card: Customized tungsten-rhenium probe card is a probe card customized according to customer needs to meet customer-specific testing needs. This type of probe card is highly customized and personalized to meet customers’ special needs.
In addition to the common types above, there are some other special types, such as tungsten-rhenium probe card with temperature control system, tungsten-rhenium probe card with pressure control system, etc. These special types of probe cards can be customized and developed as needed.
