Board-to-board (BTB) connectors are one among the preferred types of connectors that connect alerts between two printed circuit boards (PCBs) and not using a cable. At Amphenol, we provide quite a lot of high-performance board-to-board choices to fit your particular utility necessities. Board-to-board connectors might be classified into subgroups based mostly on their elementary features and utilization. Backplane connectors are one amongst the most typical and are usually seen in prime-of-rack switch purposes or HHD clusters. They are able to connecting two daughter cards through a standard PCB in the again of a chassis. A right-angle connector on every daughter card is related to the backplane with vertical connectors. When PCBs on the same plane are connected by two proper-angle connectors, they are called coplanar connectors. PCBs which are orthogonally connected are referred to as orthogonal connectors. With improved airflow, these connectors are helpful in contemporary networking configurations that implement the spine and leaf construction.
The BTB connectors that join two PCBs stacked parallel to each other at a set distance are Mezzanine connectors. Apart from the above-mentioned categories, there are additionally Card Edge connectors that connect perpendicular to the motherboard, as in PCIe®, or can connect in a coplanar configuration. Several elements decide the standard of a board-to-board connector, amongst which signal integrity is a first-rate factor, because it determines the electrical quality of interconnection. A connector with premium sign integrity may have reduced energy loss, reflections, and crosstalk. Density, which is the number of differential pairs and other signals within an area of a connector, is one other figuring out issue. As the pitch becomes smaller, the density increases. Amphenol provides board-to-board options for low and high-density applications. The distance between the two stacked interconnected boards is named stack top. In terms of mezzanine connectors, stack top is very important. Amphenol’s ExaMEZZ®, InfinX®, GIG-Array®, BergStak®, and BergStik® product families can cowl a wide range from 3mm to 63mm. Our exhausting-metric backplane connectors can be paired with our onerous-metric power connectors to ship over 100A alongside to meet high-pace alerts requirements.
Amphenol gives board-to-board solutions for every trade-normal software. XCede® and AirMax are excellent and confirmed board-to-board connectors for backplane, mezzanine, orthogonal, or coplanar solutions up to 25Gb/s. The purposes for these connectors include IEEE 10GBASE-KR and 25GBASE-KR, or OIF CEI-6G, CEI-11G, CEI-28G. ExaMAX® and Paladin are fitted to functions of 25Gb/s to 112Gb/s. Applicable industry requirements for these best-in-class connectors embody IEEE 25GBASE-KR, 50GBASE-KR, and 100GBASE-KR or OIF CEI-28G, CEI-56G, CEI-112G. Our board-to-board connectors can be used in PCIe® functions for PCB header connector riser playing cards or control alerts. XCede and AirMAX are acceptable for PCIe® Gen 1, 2, or 3, and ExaMAX® and Paladin® deliver the quickest speeds and support PCIe® Gen 4 or greater. Mini Cool Edge has been optimized for 112G card edge purposes. EnergyEdge™ X-treme’s twin contact design can handle 3000W at 12V and presents the best linear density out there out there at this time. Amphenol’s intensive range of vertical PCIe® Gen 4 and Gen 5 connectors include options for surface mount, through-hole solder, press-fit, and straddle mount terminations.
These 1.00mm pitch, vertical and proper-angle card edge connectors allow all generations of PCI Express®signaling in desktop PCs, workstations, and servers. The connector PCB header connector designs present help for 2.5GT/s (Gen 1), 5.0GT/s (Gen 2), 8.0GT/s (Gen 3), and not too long ago improve to 16GT/s (Gen 4), even additional to Gen 5 32GT/s per differential signal pair. Finally, Bergstak® is a superb possibility where cost and efficiency are paramount. It could deliver speeds over 32Gb/s and has sufficient pins for both the high-velocity and facet-band signals. Offering micro pitch from 0.4mm to 0.8mm, connector place choices from 10 to 200, and stack height flexibility from 3mm to 20mm, these connectors are designed to be used in industrial, telecom, datacom, automotive, and medical applications.

This complete vary of products is also obtainable in shielded model. Amphenol’s Cool Edge is a high speed and excessive energy card edge connector system that helps most board-to-board applications in the electronics market. Its versatility addresses multiple requirements like PCIe®, SAS, SATA, Gen 4/5, OCP 3.0, EDSFF, Gen Z, and presents multiple BTB configurations comparable to mezzanine, coplanar, mid-plane, and backplane.
Layout of the three PCBs has progressed very rapidly – far quicker than the time taken to develop the casework, by literally an order of magnitude. The boards are being done as 2-layer PCBs. It’s amazing to seek out that the cost of 5 prototype 2-layer PCBs is around $50 for a 48-hour turnaround. In comparison with $500 for even a 4-layer High-speed PCB connector that takes over a month to be delivered, the decision to attempt to make all the PCBs as 2-layer makes a lot of sense. The Laptop’s PCBs are divided into three parts, for a number of reasons. Firstly: to place all the components onto a single 12in-lengthy PCB doesn’t make sense. The form can be flimsy, awkward to cut, and would have vital void areas. Secondly: the facility PCB for the Battery Charger IC must be 2oz copper (it is coping with 15 watts) whereas the rest of the design doesn’t.
