Types of PCB Connectors
PCB connectors come in many types. They can be classified according to their gender, termination methods and power handling capabilities.
Board-to-board connectors allow you to connect two printed circuit boards without using cables or wires for signal transfer. They also improve device manufacturability by allowing you to install components in smaller sub-systems that can later be plugged together.
Headers
Headers are a key component in the design of printed circuit boards, providing a way to connect conductors to the board. They’re available in a variety of forms, pitches, heights, and mounting orientations to suit different applications. In addition, some are polarized or keyed to prevent incorrect connections and ensure that the connector is plugged in properly.
Moreover, the headers can be either male or female. Gender refers to whether the connector plugs into or gets plugged into the board, and this determines how it should be connected to another connector. Some headers are also shrouded, which means that the pins are surrounded by a box to make them more secure and prevent them from bending or being pulled out.
A pin header is a male connector with one or two rows of pins attached to a plastic base. The number of pins can vary, as can the spacing between them (known as the pitch). The most common types of headers have either single or double row of pins, but other variations are also available.
These types of connectors are used to connect conductors to the PCB for transmission of signals, data, and power. They’re characterized by their large current capacity and high-speed transmission capabilities, which can reach up to 28 Gbps. They’re typically found in applications like data processing and storage systems, telecommunications devices, and industrial equipment.
There are many different types of headers to choose from, ranging from 0.1” up to 0.635” in pitch. Choosing the right header depends on several factors, including its overall size and how much space pcb connector types it will take up on the circuit board. A smaller pitch will allow for a higher number of contacts in a small footprint, while a larger one will help streamline production and mating.
The type of header that’s best for your circuit board will depend on the type of signal you need to transmit and the amount of current required to power it. For example, a pin header is a good choice for transmitting MIDI and audio signals, while a DIN connector can be used to carry high-definition video and audio signals.
Other considerations when selecting a header include its mounting method and the orientation of the pins. There are two primary methods for mounting a header to a circuit board: surface mount and through hole. Surface mount headers are attached to the top of the PCB by soldering them in place, while through hole headers are placed inside the circuit board and soldered from the back.
Wafer Connectors
A wafer connector is a type of pcb pin connector that sits on top of a printed circuit board. Its primary function is to provide an electrical connection between two components on the board. It is available in a variety of sizes and PCB Connector Types Supplier types to suit various electronic applications. Wafer connectors are also used in wafer scanners, a critical component for applying structures to semiconductor wafers. Without these machines, the modern information society would not be possible.
There are many different pcb connector types available, and it is up to the designer to choose the right one for their project. Several factors are involved in this decision, including cost, signal transmission speed, and the ability to mate and demate the connector with ease. Another factor to consider is the environment in which the connector will be used, since some are designed for more hostile environments than others. For example, some are made to withstand vibration, kinetic shock, shielding, environmental ingress, oils, chemicals, and corrosion.
Among the most common pcb connector types is the edge-to-edge connector. This connector has 25 strips that can accommodate a wide range of different pins and plugs. Its most important feature, however, is the fact that it provides direct access to an external circuit.
The other main category of pcb connectors is the board-to-board connector. This type of pcb pin connector has a female or male gender to accomplish mating cycles. These female or male genders allow the connector to be connected and disconnected thousands of times before breaking down.
A third type of pcb connector is the cable-to-board connector. This type of connector has one end that is attached to a wire or cable, and the other end is attached to a PCB through either a crimping or insulation displacement contact. These connectors can be found in a number of industries, such as automotive, industrial, and telecommunications.
When selecting a pcb connector, the designer should also take into account the connector’s pitch and size. These parameters determine the distance between the connector’s contacts and can affect the physical/mechanical efficiency of a design. For example, a minuscule pitch can offer more pins in a smaller space but may be difficult and time-consuming to manufacture. A larger pitch, on the other hand, streamlines production and mating but limits the number of pins that can be used within an assigned area. In addition to these considerations, the designer should also pay attention to a connector’s pin holders and housing. These features are crucial in determining how the connector is mounted on a PCB. They are also responsible for how the connector is cleaned and maintained.
