The QTE-020-03-L-D-K-TR rectangular array edge type mezzanine connector is used for board-to-board connections. It is a relatively simple yet powerful assembly that is well-suited for applications requiring secure connections between two surfaces. This article discusses the application field and working principle of the QTE-020-03-L-D-K-TR connector.

Description

The QTE-020-03-L-D-K-TR rectangular array edge type mezzanine connector has three rows of contacts, arranged in a 0.2” x 0.3” pattern. It is available in two different configurations: a right-angle (L-shaped) board, and a straight (D-shaped) board. The connectors are made with high-temperature plastic and high-frequency insulation materials that are both UL94V-0 certified. The terminals are either gold plated or tin plated, depending on the customer\'s requirements. The gold plating provides better signal integrity and temperature resistance, while the tin plating is more cost effective.

Application Field

The QTE-020-03-L-D-K-TR rectangular array edge type mezzanine connector is primarily used in the telecom industry for connecting main boards for high-speed signal transmission. It is also suitable for other applications requiring high performance in a cost-effective package, such as automated test equipment (ATE), industrial control, computers, and robotics. The array type structure of the connector enables a high degree of flexibility in terms of design, and the 2mm pitch ensures a secure connection.

Working Principle

The QTE-020-03-L-D-K-TR rectangular array edge type mezzanine connector works by utilizing a contact system in which sharp edges of the contact blades pierce, puncture and cut into the insulation material on both sides of the connection. This enables the blades to make electrical contact with the mating board, which ensures reliable connections. The connector also utilizes surface mount technology (SMT), which is a low-cost, high-speed method of establishing connections between components on a motherboard. The SMT technology enables the connector to be mounted directly onto a board or onto a socket strip. It is also compatible with mounting standards such as those set by the JEDEC association.

Conclusion

The QTE-020-03-L-D-K-TR rectangular array edge type mezzanine connector is a versatile, cost-effective solution for board-to-board connections. It is suitable for a variety of applications including telecom, ATE, industrial control, computers, and robotics. The connector utilizes sharp contact blades for secure connections and SMT technology for mounting directly onto a board or onto a socket strip. This makes it an ideal choice for applications requiring reliable connections between two surfaces.
