Connector PCB Miracle
Connector PCB Miracle is a crucial component of any modern electronic device. These components are responsible for connecting the various circuits and ensuring that the device functions properly. They are designed to withstand various types of stress and environmental conditions. There are several different types of connectors. This article will discuss some of the most common.
High-Reliability
There are sectors where unfailing electrical connectivity is imperative. These include industries such as Space, Aviation or Defense where a failure could threaten human life. Such demanding environments require a high-reliability PCB connector that will remain durable and stable despite environmental extremes. A high-reliability PCB is designed to resist vibration, shock and temperature changes. It will also be able to withstand moisture exposure, even after repeated uses.
Vibration is a continuous shaking, often with a variable frequency and amplitude. Shock is a single, sudden impact. Both of these can affect a connector’s ability to maintain a connection with its mating partner. To help with this, a high-reliability PCB connector will usually have two separate design features. Firstly, it should have more contact beams in the actual connector contact area (rather than just 2 for example) to ensure that there will always be at least one maintaining contact. Secondly, it should have a method of fixing the two connector halves together such as jackscrews or latches to prevent them being pulled apart during vibration.
The KA series from Amphenol Industrial Operations is an ideal example of this, and offers signal contacts compliant with MIL-DTL-55302 as well as power and fiber optic contacts up to 15A each. It also has machined aluminum shells, diallyl phthalate insulator and a 36-position polarization key system to prevent cross plugging.
High-Density
High-density PCB connectors allow a larger number of signal transmission channels per unit area. They are often characterized by a smaller footprint and higher pin count than other PCB connector types. They are available in a range of configurations, including co-planar and right-angle versions. These high-density connectors can be used as both board-to-board and wire-to-board connections.
They are designed to meet the demands of space-constrained electronic circuits. They are aimed at downsizing board dimensions while Connector PCB Miracle maintaining current and power handling capabilities. They are also capable of supporting high-speed signal transmission.
The design of these high-density PCB connectors includes a merger of signals, power, and grounding into a single pinout. This helps in increasing the signal count handled by them while saving space on the Connector PCB Miracle Supplier PCB. The result is a smaller footprint and low-profile connector.
Samtec’s HDLP series of high-density PCB connectors can reduce the amount of real estate needed for making data connections by encapsulating a large number of contacts within a small footprint. They can be used for PCB-to-PCB, flying lead, and mezzanine applications. These connectors can also be mated to each other or to flying leads, and they offer IP67 sealing when mated. This makes them suitable for missile guidance and propulsion systems, ruggedized computer systems, camera or display applications, and communications panels and enclosures.
High-Speed
A high-speed PCB connector is designed to provide a low contact resistance and a large number of mating cycles. This can minimize signal degradation and ensure reliable operation. It can also help to increase the data transmission rate and the power delivery capacity of a circuit board.
There are several different types of high-speed PCB connectors available on the market, depending on the final application. Some are more robust and can withstand harsh environments, while others are more sensitive and designed for a high level of accuracy. The type of connector you choose should be determined by the Size, Weight and Power (SWaP) requirements of your design.
The KMC Series offers a range of high-density signal connector solutions for board to board and wire to board applications. The family is offered with a wide selection of contact sizes and termination methods including both dip solder and SMT soldering. The connectors are also available in a space grade version to meet the demands of harsh environment applications.
Using high-speed signal pairs on a PCB requires special care when routing them. It’s important to reduce the length of pin stubs on each layer, and to make sure that signals enter the connectors at their closest point to each other. In addition, it’s important to use differential pin assignments to prevent mode conversion from common to differential, and to route the pair’s grounding pin to an appropriate location on the board.
Multilayer
PCB Connectors are used to connect conductors to Printed Circuit Boards (PCBs) for the transmission of signals and current. They are available in a wide variety of shapes, pitches and current strengths, allowing them to be used for virtually all Industrial applications. For example, the COMBICON family of modular signal interconnect systems offers plug and socket connectors for board-to-board and wire-to-board or wire-to-wire connections. They are compact, light and have high power capacities. PCB connectors can also be used to transfer signals within an embedded system, such as a mobile phone or automobile. The final application will determine the size, weight and power (SWaP) requirements of the connectors used in a particular design.
