MEMS Probe card- Probe
The MEMS probe production line of Lingang factory was officially put into operation in December 2021

ZENFOCUS started the research and development of probe materials and built its production line in 2019, and has completed the development of a number of advanced materials so far. A number of MEMS probes have been adapted to different pitches and CCC, among which 2D MEMS probes have been widely used in the testing of mobile phone processor AP, high-performance computing HPC, intelligent AI and vehicle RF chip products. 3D MEMS probes have been widely used in wafer testing of Nand Flash and DRAM memory products.

MEMS Probe Card - 2D probe
Products advantages

The structure design of vertical probe can meet the testing requirements of high density and fine spacing for large-scale BGA array chip, and automatic pin implantation can be realized through automatic equipment, which is efficient and cheap

01

The multi-component alloy probe material has the advantages of extreme strength and hardness, enabling the fatigue life of the probe pin to exceed 1 million times and reducing the frequency of maintenance of the probe card

02

The advanced production artistry guarantees the precision of the probe, and makes the probe card have extremely high flatness and test stability

03

The size and structure of the probe pin tip can be customized to meet the special needs of the chip probe marking and we can cooperate with customers for early marking verification tests

04

Fully localized probe production reduces the probe design, manufacturing and testing cycle to 10 days and offers customized probes according to customer testing requirements

MEMS Probe Card- 3D probe
Products advantages

The micro-integration technology of the micro-cantilever probe structure enables the probe to have extremely high dimensional accuracy, smaller pin mark slip, and supports the test of small pad.;

01

The hardness of the probe material is more than 450HV, and the hardness of the tip can reach 600HV after rhodium plating. The contact impedance of the probe is stable, and the wear resistance of the tip is very high.

02

The probe has high conductivity and supports both high and low temperature tests. The parasitic capacitance is reduced by more than 50% compared with the traditional cantilever probe.

03

The size and structure of the probe tip can be customized to meet the special needs of the chip probe marking, and we can cooperate with customers for early marking verification test.
