ProductsHand-Press Fixture (Manual Press Machine)
Simple, Reliable Electrical Testing — Right at Your Fingertips
Seiken’s Manual Press Machine delivers reliable and stable electrical contact in a compact, user-friendly form—no automation required. With a single downward motion, the lever-driven mechanism ensures precise probe engagement with your device under test, enabling accurate measurements with minimal setup.
Designed for low-volume production, prototyping, and environments where space is limited, this tabletop solution offers a flexible, cost-effective alternative to automated handlers—without compromising on performance.
Whether you’re testing high-density semiconductors, PCBs, or components with uneven surfaces, Seiken can tailor every detail to match your device specifications for optimal contact and accuracy.
The Structure of Hand Press Machines
The manual press machine is designed with three main sections:
- Press Frame: Applies consistent downward force through a lever-operated mechanism.
- Pin Board: Holds contact probes and ensures precise alignment with the device.
- Stage: Secures your test device in place.
For a complete inspection setup, optional integrations include signal connectors, vacuum holding systems, and XYθ adjustments for enhanced precision and usability.
