Many users and customers are concerned about board edge connector solutions and are looking for more reliable alternatives. After all, edge-socket connectors are not suitable for harsh environments exposed to strong vibrations and shocks. Corrosion due to wear can also occur, with improperly designed and manufactured contacts wearing down due to vibration. In contrast, SMC and MicroSpeed ​​are reliable connector systems that, with their double-foil contacts, ensure a good contact solder length and a secure connection, while meeting demanding requirements thanks to their high-quality contact surfaces.

The trend is moving towards custom solutions optimized for specific requirements. This is where the concept of mini backplanes comes in, offering maximum performance, minimal space requirements, and a high level of reliability. High-performance fine-pitch connectors, such as ERNI Electronics' SMC and MicroSpeed ​​components, enable the design of compact systems with high data transmission speeds.

SMC connectors with a 1.27 mm pitch have been successfully established in the market for approximately 20 years and have undergone robust development. These connectors are frequently used in numerous locations within a system, whether for mezzanine, flat cable, or coplanar configurations. Unshielded SMC connectors for applications without special high-speed requirements have been used in millions of units in applications such as programmable logic controllers (PLCs). Furthermore, SMC connectors are also available with highly reliable press-fit technology, making them ideal for passive backplanes.

For more demanding applications, the high-speed MicroSpeed ​​connectors with a 1.0 mm pitch and their corresponding power modules are the ideal choice. They can also be adapted for high-speed serial interconnects such as PCI Express 1/2/3, Rapid IO, SATA 1 and 2, Fibre Channel, USB 3, and 10 Gigabit Ethernet (10GBASE-T or KR). Like shielded connectors, MicroSpeed ​​components are also ideal for applications with open EMC enclosures or those meeting particularly stringent EMC performance requirements.

Along with the SMC-based demonstrators for mini backplanes presented earlier, ERNI Electronics has also developed corresponding MicroSpeed-based systems in order to highlight the many different options offered by these connector families.
