ProductsHC-C IC Sockets
The Ultimate Solution for High-Current and Heat-Resistant Testing
Seiken’s HC-C IC Socket is engineered for high-current applications, featuring our proprietary leaf spring structure that delivers exceptional current-carrying capacity per terminal. Designed for stability and reliability, the HC-C ensures consistent electrical performance, even under demanding conditions.
Unlike conventional sockets where terminals are embedded in resin housings, Seiken offers the option of metal housings in high-current regions—such as around emitter electrodes. This innovation effectively dissipates both heat and current, minimizing terminal degradation (e.g., load loss) and extending socket lifespan. Additionally, we can customize socket designs to allow for individual signal extraction for emitter and gate terminals, even when dealing with complex peripheral electrode layouts.
At Seiken, we deliver fully tailored IC sockets and inspection fixtures to meet your exact testing requirements.
General Specifications
Standard terminals are typically mounted in resin housings. However, for emitter electrodes that require high current, metal housings can be used instead. This enhances current handling and heat dissipation, reducing the risk of terminal degradation, such as reduced spring force. Additionally, configurations that separate signal extraction from the emitter and gate terminals are available, enabling flexible electrode design.

Key Features & Advantages
01 Superior high-current and heat dissipation design
By efficiently dispersing heat and current, HC-C sockets achieve durability, maintaining stable performance even under intensive high-current operation.
02 One-stop custom design — From prototyping to mass production
Seiken provides end-to-end service—from initial design to final manufacturing—based on your device’s specific size, shape, and test conditions.
We offer flexible production starting from a single unit, allowing for easy adoption even at the prototype development stage.
HC-C (High Current Cube) Blocks
To enhance versatility and cost-effectiveness, Seiken also offers a universal HC-C block as a standard product.
Despite its compact size (approx. 10mm along the long side), each block supports up to eight high-current terminals, handling a total current capacity of up to 400A per block.
Features and Applications: (For power modules)
- Freely arrange blocks to suit your device’s layout and testing requirements.
- Combine multiple blocks to handle currents of 400A × number of blocks.
- Easily accommodate non-standard lead pitches that are difficult for conventional socket designs.
- Improve testing flexibility for power modules and custom applications.
Additionally, Seiken can integrate HC-C blocks into fully customized IC socket designs, offering the ideal combination of flexibility and performance for your inspection environment. Experience the difference with Seiken’s HC-C solutions—where innovation meets reliability.
