Anyone who’s ever looked inside an previous desktop pc and unplugged a ribbon cable is accustomed to the humble pin header. This connector is an easy however efficient means to connect two boards collectively in a stacked association. 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 outdoors the maker space. In a latest engagement with a shopper, I used to be shocked to see how they'd stacked up a number of Raspberry Pi boards to run some vital tools, which shows the significance of board-to-board connectors in some of these modular programs. Though pin headers are easy, it doesn’t mean they aren’t helpful. However, they aren’t the one choice, and there are numerous board-to-board connector options for high pace/excessive frequency programs, or for high voltage/high energy methods. These connectors find their means into techniques as numerous as military gear to medical equipment. If you’re taking a modular design approach to your subsequent hardware platform and you have to hyperlink a number of boards together easily, consider board-to-board connectors as an alternative of cables.
There are many price-efficient options in the marketplace that may ensure sign integrity and rugged design in a range of methods. Board-to-board connectors are available a wide range of sizes and styles to provide a modular 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 type, together with stacked pin headers. Pin headers could be shrouded and SMT PCB connector keyed (even multi-keyed) to guarantee pinouts match when boards are related. Mezzanine connectors: This kind of board-to-board connector joins two parallel printed circuit boards in a stacked configuration. There are many mezzanine connector types. Note that a pin header can be used as a mezzanine connector. Edge card connectors: This model connector is mostly recognized for its use in RAM sticks and COMs/SoMs. Really, it can be utilized for any board-to-board connection alongside a board edge, whether with a customized or standardized pinout.

Standardized connectors: Some connectors could also be developed to satisfy very specific trade standards past edge connector kinds for add-in cards. Standards organizations which have outlined specific connector types include VITA (for backplanes), PCI-SIG (PCIe playing cards), IEEE (e.g., 1386 commonplace for mezzanine), JTAG, Pc/104 (sq. For those who have almost any inquiries about exactly where as well as how you can utilize High-density PCB connector cost, it is possible to email us from the web site. -submit pin headers), and others. There are various other connectors that don’t fall into one of the above classes. The image beneath exhibits an example of some typical merchandise that fall inside these categories. The image above is only a subset of all of the totally different board-to-board connectors out there on the market. Obviously, there are many variations on these connectors with completely different pin/pad counts, key/shroud kinds, mounting kinds (SMD vs. When you’re trying through a vendor’s webpage or filtering by way of a elements search engine, there are a couple of other ways distributors will categorize their parts.
Within these several types of board-to-board connectors, they could also be categorized as ruggedized, excessive speed, excessive frequency, high present/high energy, or another designation. This is basically marketing speak as there isn't any universal definition of a high velocity connector, excessive energy connector, etc. One necessary exception is backplane connectors, that are strictly defined within the ANSI/VITA requirements, where particular kinds pair with different media (copper, fiber, or coaxial cable). Another extremely standardized connector style is the IEEE 1386 mezzanine connector. As is the case with many different components, distributors will target specific industries with their merchandise and can strive to target particular functions in these industries. As a result, PCB connector assembly you’ll see styles of board-to-board connectors that might be extremely ruggedized with exhausting plastic shielding as they goal areas like automotive, aerospace, industrial techniques, or power merchandise. Usually, you'll be able to normally discover a ruggedized model of a regular connector that has the same pinout, mounting model, and pitch as its much less rugged variant.
