B20B-PADSS-1

B20B-PADSS-1 Application Field and Working Principle

The B20B-PADSS-1 from JST is a 1.25mm pitch, Single-Row Type SMT Board-to-Board connector with a P.C.B. height of 0.9mm. It features dual-row and reverse-staggered mating with 20-pin compact horizontal connections.

The application field and working principle of the B20B-PADSS-1 connector are as follows:

Application Field

• Flat panel displays
• Mobile phones
• Notebook PCs
• Digital cameras
• High-density applications

Working Principle

The working principle of the B20B-PADSS-1 connector is based on a dual-row and reverse-staggered mating configuration. This configuration enables the connector to easily support high-density connections due to its small footprints and light weight. It also helps reduce the amount of space needed for wiring, allowing more compact designs.

The B20B-PADSS-1 connector works through two primary contact elements, the male pins and female headers. The male pins on the top side of the connector are made of highly resistant stainless steel, and they mate with the female headers at the bottom of the connector. The contact elements are pressed together with a floating self-adjusting structure, providing a safe connection that can last for prolonged periods of time.

In terms of usability, the connector also features a unique force-fit design that allows for quick and easy locking and unlocking. This prevents any potential need for tools during maintenance and repairs, resulting in a much more efficient connection.

Advantages

• High-density connection
• Small footprint and light weight
• Floating self-adjusting structure
• Quick-locking/unlocking mechanism
• Tool-free repairs and maintenance

Disadvantages

• Costly acquisition
• Susceptible to EMI (Electromagnetic Interference)
• Warranty period limited by user environment

Conclusion

The B20B-PADSS-1 connector from JST is a great option for any product requiring a compact connection with a high-density design. Featuring dual-row and reverse-staggered mating, floating self-adjusting contact elements, a quick-locking/unlocking mechanism, and tool-free repairs and maintenance, the connector is both secure and reliable. While its acquisition cost is somewhat expensive, the connector provides a number of useful features that greatly outweigh the cost.
