Introduction to connectors for electronic cards

Connectors for electronic cards are electrical components designed to facilitate the physical and electrical interconnection between different printed circuits, modules or electronic devices. Its main function is to allow the transmission of electrical signals, energy or data through a secure, reliable and detachable interface, facilitating the assembly, maintenance and repair of electronic systems.

These connectors are essential in the manufacture of modern electronic devices, as they allow modularity and flexibility of design, enable the integration of various components and ensure circuit continuity without the need for permanent soldering. The variety of types and configurations available adapts to the different technical and spatial needs in electronics.

Edge connectors

Edge connectors are those that connect to the edge of an electronic card, taking advantage of the conductive tracks exposed at that end. This type of connector is common on expansion cards and modules that require a fast and secure connection, such as memory cards and motherboards.

Their design allows for easy insertion and removal, and they are generally composed of metal contacts housed in an insulating body. Precision manufacturing is critical to ensure reliable contact and prevent damage to printed circuit boards.

These connectors are widely used in industrial, computing and telecommunications applications due to their robustness and ease of use.

Pin connectors (Pin headers)

Pin connectors consist of rows of metal pins arranged in a plastic base, which are inserted into through holes or soldered directly onto the electronic board. They are one of the most common and versatile types for making connections between boards and modules.

There are variants such as male, female, double row or single row pins, and they can have different pitches (distance between pins), which allows adaptation to multiple designs and technical requirements.
