Anyone who’s ever looked inside an previous desktop laptop and unplugged a ribbon cable is conversant in the humble pin header. This connector is an easy however efficient method to attach two boards together in a stacked arrangement. In actual fact, it’s so widespread that it’s been used to construct add-on shield boards for common platforms like Arduino and Raspberry Pi, both of which have seen success outside the maker house. In a current engagement with a shopper, I used to be shocked to see how they had stacked up multiple Raspberry Pi boards to run some essential equipment, which exhibits the significance of board-to-board connectors in these types of modular programs. Even though pin headers are easy, it doesn’t mean they aren’t helpful. However, they aren’t the only option, and there are a lot of board-to-board connector choices for top pace/high frequency techniques, or for top voltage/excessive energy techniques. These connectors find their way into techniques as various as navy gear to medical tools. If you’re taking a modular design approach to your next hardware platform and you need to link a number of boards collectively simply, consider board-to-board connectors instead of cables.
There are lots of cost-effective choices in the marketplace that may guarantee signal integrity and rugged design in a variety of systems. Board-to-board connectors are available in a wide range of sizes and shapes to provide a modular really feel to a multi-board PCB system. Pin headers: Most designers are aware of the 1-row or 2-row pin header association with 1 mm pitch. There are variations on this style, together with stacked pin headers. Pin headers may be shrouded and keyed (even multi-keyed) to ensure pinouts match when boards are related. Mezzanine connectors: One of these board-to-board connector joins two parallel printed circuit boards in a stacked configuration. There are a lot of mezzanine connector styles. Note that a pin header can be utilized as a mezzanine connector. Edge card connectors: This style connector is most commonly identified for its use in RAM sticks and COMs/SoMs. Really, it can be used for any board-to-board connection alongside a board edge, whether or not with a customized or standardized pinout.

Standardized connectors: Some connectors may be developed to meet very particular industry requirements beyond edge connector styles for add-in playing cards. Standards organizations which have outlined specific connector styles embrace VITA (for backplanes), PCI-SIG (PCIe cards), IEEE (e.g., 1386 customary for mezzanine), JTAG, Pc/104 (sq. Here's more information about SMT PCB header connector connector; just click the following internet site, take a look at our web-page. -publish pin headers), and others. There are many other connectors that don’t fall into one of the above classes. The image under exhibits an example of some typical merchandise that fall within these categories. The image above is just a subset of all the totally different board-to-board connectors available in the marketplace. Obviously, there are numerous variations on these connectors with completely different pin/pad counts, key/shroud styles, mounting styles (SMD vs. When you’re wanting by a vendor’s website or filtering through a parts search engine, there are a number of other ways vendors will categorize their parts.
Within these different types of board-to-board connectors, they could also be classified as ruggedized, high velocity, excessive frequency, high current/excessive power, or another designation. This is essentially marketing speak as there isn't any universal definition of a excessive pace connector, excessive energy connector, and so forth. One essential exception is backplane connectors, which are strictly outlined within the ANSI/VITA standards, where specific kinds pair with completely different media (copper, fiber, or coaxial cable). Another extremely standardized connector model is the IEEE 1386 mezzanine connector. As is the case with many different components, High-speed PCB connector distributors will goal specific industries with their merchandise and can attempt to target particular purposes in those industries. Because of this, you’ll see types of board-to-board connectors that is perhaps extremely ruggedized with hard plastic shielding as they goal areas like automotive, aerospace, industrial systems, or power products. In general, you'll be able to normally discover a ruggedized model of an ordinary connector that has the same pinout, mounting type, and pitch as its much less rugged variant.
