FAQ

A contact probe is a component normally used to test the electrical conductivity of electronic devices such as semiconductors, circuit boards, and more. It typically consists of three parts: a plunger (tip), a barrel (housing), and a spring (to control contact pressure). When properly matched to the application, it ensures stable, accurate signal transmission during testing.

Choosing the ideal probe depends on n several factors, inlcuding your device under test—whether it’s a semiconductor, PCB, or IC—as well as factors such as terminal size and pitch, durability requirements, heat resistance, and spring force. Our team is available to help you identify the best probe for your specific conditions and testing environment.

Key considerations include the shape and material of the tip, surface coating, and electrical parameters like current capacity and signal frequency. The right combination ensures reliable contact and optimal performance for your testing needs.

We offer a wide variety of IC sockets, ranging from standard models to fully customized solutions. Whether you need general-purpose sockets or highly specialized designs, we’re equipped to meet your needs.

Recommended hole diameters vary by product. Please consult our product catalog for detailed specifications. Adjustments may be necessary depending on the material used.

All our lead wire types are heat-resistant up to approximately 150°C, regardless of wire thickness.

We generally recommend rounded-tip probes for FPC applications. However, needle-type tips may offer more consistent contact if rust-prevention treatments are involved.

Our solutions are designed to test a wide variety of devices, including wafers, IC packages, discrete components, PCBs, batteries, and LCD panels. If your application involves terminal-based electrical testing, we likely have a compatible solution.

We support pitches as small as 0.13mm for double-ended probes and 0.45mm for single-ended types. Please note that ultra-fine pitches, precision alignment and strict tolerances are essential to ensure consistent contact.

Absolutely. Once the prototype is evaluated and approved, we can move into full-scale production. Reach out to us to discuss your specific requirements.

Our contact probes are engineered to operate within a wide temperature range of -40°C to +150°C. We also offer high-temperature models for more demanding environments.

It depends on the materials used. For special temperature conditions, we’ll propose the most suitable materials based on your requirements.

Lifespan varies depending on probe type and test conditions but generally ranges from several hundred thousand to several million cycles.

Voltage capacity is influenced by the spacing between probes. As a general rule, 0.1mm spacing can handle approximately 100V.

Yes. We offer flexible integration options and can customize probes to fit a wide range of test systems and fixtures. Let us know your current setup—we’re happy to assist.

Mechanically, replacement is needed if you notice sticking, reduced spring force, or a broken spring. Electrically, signs include increased resistance caused by tip wear or contamination, which can lead to reduced testing accuracy.

In most cases, probes can be removed and replaced directly from the socket. If your setup does not use a socket, replacement procedures may vary. Please contact us for assistance.

For probes, regular cleaning is key. For IC sockets, using wear-resistant materials (e.g., ceramic guide parts) and design with component size tolerances can significantly enhance durability.

There are several cleaning methods available. You can use cleaning sheets or a dedicated brush to gently remove debris from the probe tip. Be sure to choose a method that best suits your specific testing conditions.

You can request a quote through the inquiry form on our website. Our team will respond promptly with the details you need.

For standard probes in small quantities, shipping is typically completed within a few days. After that, delivery time will depend on the shipping service used for international orders. For more complex items like jigs or fixtures, it may take several weeks. Exact delivery times will be provided to secure your package.

Yes, samples of catalog-listed products are available. If shipping overseas, we kindly ask that you cover the shipping costs. Please contact us to confirm availability, shipping options, and any other relevant details.

Custom items usually require 4–6 weeks for initial production after all arrangements have been made, but this may vary depending on the design and manufacturing process. A detailed schedule will be provided for each order.

For probes, the minimum order is 100 units. However, some catalog items listed on MISUMI, this items are available starting from just one unit.

Yes. We can manufacture and supply even a single unit of a test jig or fixture. Please contact us for more information.
