Layered probe "High current, multi-point layered probe (patented technology)"

Layered probe "High current, multi-point layered probe (patented technology)"

As an inspection of the front-end process of power semiconductors, applying uniformly at multiple points on the wafer surface reduces the burden on the semiconductor.

This is a probe developed with innovative technology, featuring excellent characteristics. We have developed a multi-point laminated probe specifically for power semiconductors, applying the characteristics of a laminated structure consisting of metal plates (probes) and insulators. 【Features】 - The probe tip is shaped like a wave, allowing contact with the semiconductor at multiple points. This disperses the amount of current and voltage applied, reducing the burden on the semiconductor. - It can move vertically by about 1 millimeter, minimizing contact marks. - Its compact design makes it easy to secure installation space. *For more details, please download the PDF or contact us.

Layered probe with stable contact resistance value.

Layered probe with stable contact resistance value.

A probe capable of achieving a stable contact resistance value according to the shape of the target object.

The "laminated probe" has been developed with innovative technology and possesses excellent features. Unlike conventional spring probes, which consist of multiple parts, it achieves a structurally stable contact resistance value through contact with a single metal plate. Even when the inspected object is not smooth, the spring properties of each probe allow it to conform to the shape of the object, enabling a stable contact resistance value. 【Features】 ■ Wiping action occurs due to the structure ■ Contact position is displaced ■ Contact can be made while removing oxide films and foreign substances from the object ■ Stable contact can be achieved *For more details, please refer to the PDF document or feel free to contact us.

Stable contact with BGA.

Stable contact with BGA.

Introducing examples of layered probes. Coating applied to the probe tip achieves extended lifespan.

We would like to introduce stable contact for BGA "laminated probes" handled by our company. For spherical BGA (solder), contact using needle-type probes, including spring probes, has resulted in slippage, making stable contact difficult. By using laminated probes for Kelvin contact, we achieve stable contact. Additionally, since BGA primarily consists of tin, applying a coating to the probe tip that suppresses tin transfer can also extend its lifespan. 【Features of Laminated Probes】 ■ Stable contact resistance values ■ Effective for precise measurements ■ Capable of handling high current and high voltage ■ Compatible with narrow pitches ■ Load for contact can be adjusted *For more details, please refer to the PDF document or feel free to contact us.

Q&A on Layered Probes

Q&A on Layered Probes

We will answer five representative questions about layered probes.

In this document, we will introduce questions regarding the "stacked probe" of the probe business handled by Inks Corporation. Q: Is non-magnetic compatibility possible? A: Yes, it is possible. The probe is made of non-magnetic beryllium copper, and the holder that holds the probe can also be made of non-magnetic materials such as aluminum or resin. Additionally, we have experience with contacts to magnetic sensor packages. We have answered five questions, including the following: - Is non-magnetic compatibility possible? - Can it be used in the previous process (wafer inspection)? - I would like to install it on the machine I am currently using; is that possible? - How should maintenance be performed? - What would the estimated schedule be until delivery? *For more details, please refer to the PDF document or feel free to contact us.

Layered Probe: Response to High Current and High Temperature

We have a track record of producing laminated probes compatible with 2000A! Introducing our solutions for handling high current and high temperatures.

The "laminated probe" does not use coil springs and instead utilizes the characteristics of leaf springs for contact, making it resistant to degradation of spring properties due to heat. The insulating film (polyimide) also has a heat resistance rating of 300°C for regular use and long-term heat resistance. It can accommodate measurement environments at high temperatures, allowing contact with power semiconductors including SiC. 【Features】 ■ Utilizes the characteristics of leaf springs ■ Resistant to degradation of spring properties due to heat ■ Can accommodate measurement environments at high temperatures ■ Allows contact with power semiconductors including SiC *For more details, please refer to the PDF document or feel free to contact us.

Features of layered probes

Features of layered probes

Reduce the burden on semiconductors and mitigate the risks of full inspection! Enable compatibility with various pitches.

We would like to introduce the features of the Inks' layered probe. The semi-layered probe contacts with a single metal plate, allowing for measurements with structurally stable contact resistance. Additionally, it is resistant to degradation of spring properties due to heat, making it suitable for measuring power semiconductors that apply high current and high voltage. It can make contact with points arranged in narrow pitches, such as semiconductor lead parts and connector contacts, up to a maximum pitch of 0.05. Furthermore, by varying the shape of the probe body and the thickness of the auxiliary V-shaped leaf spring, it is possible to adjust the load from high to low continuously. 【Features】 ■ Stable contact resistance value (demonstrates power in precise measurements) ■ Supports high current and high voltage (contributes to application and measurement of power semiconductors) ■ Compatible with narrow pitches (up to a maximum of 0.05 pitch) ■ Adjustable contact load (contact tailored to the characteristics of the measured object) *For more details, please refer to the external link page or feel free to contact us.

[Example] Stable contact of the stacked probe

[Example] Stable contact of the stacked probe

Introduction to stable contact with the package lead.

The wiping effect of the "stacked probe" removes the oxide film while making contact, achieving stable contact. Additionally, a coating that suppresses tin transfer has been applied to the probe tip, resulting in increased longevity. For magnetic sensor packages, it is also possible to construct the probe unit using only non-magnetic materials. In this case, stable contact was achieved with 2 million cycles of no maintenance. 【Features of the Stacked Probe】 ■ Stable contact resistance values ■ Excellent for precise measurements ■ Capable of handling high current and high voltage ■ Compatible with narrow pitches ■ Load for contact can be adjusted *For more details, please refer to the PDF document or feel free to contact us.
