Backplane Connectors - Specialized consists of systems that allow physical attachment of components in devices like computers, communication systems, and industrial equipment. Although numerous types of specialized connectors exist, one specific types is the 72387-1021LF. Here, the application field and working principle of this component is discussed.

The 72387-1021LF, manufactured by Amphenol, is a 1.27-mm (.050-in) thick double contact, solder tail board-to-board connector. It normally comes in a tape-and-reel package which is suitable for automated assembly machines. This connector is commonly used in motherboard-to-daughterboard applications and provides optimum shielding of signals. Offered in a low-profile design, the 72387-1021LF allows a space-saving interconnect solution.

This connector is designed to mate with 2mm board connectors. It has two 98-contact positions with a power rating of 0.4A per contact. The mating force is 5 to 7N and the 72387-1021LF has an operating temperature range between -55 to 125°C (-67 to 257°F). In addition, this board-to-board connector is vibration- and shock-proof, and the gold plated contacts provide excellent electrical performance.

The 72387-1021LF is designed for high-density applications in microelectronic systems like networking and telecommunication equipment, and computer motherboards. It is popularly used in automotive lighting applications because of its low profile, vibration-proof feature and high temperature durability. Transport-related applications also employ this connector due to the seismic environment. In the medical industry, this connector is a preferred choice due to its excellent signal performance.

The functionality of the 72387-1021LF is based on its solder tail design. The two contacts on either side of each socket are mounted inside the holding clips. The socket features a closure mechanism, which allows it to be securely fastened onto the panel. The two contacts on either side of the socket are soldered onto the board, creating a robust electrical connection.

Typically, in a soldering process, the soldering iron is used to heat up the solder and make it melt. This molten solder then flows into the gaps between the connector and the board. As the solder cools, it binds the two components together. The amount of solder applied per contact must adhere to the recommended standards, in order to ensure a strong and lasting electrical connection.

In conclusion, the 72387-1021LF from Amphenol is a specialized backplane connector that offers a space-saving interconnect solution. It is typically used in high-density applications such as automotive lighting, transportation, and medical equipment. Its working principle is based on its solder tail design, in which the two contacts are soldered onto the board to create a strong electrical connection. By utilizing this interconnect solution, designers can create reliable products with better performance and more energy efficiency.
