ERNI Electronics have expanded their 0.8mm MicroStac SMT connector series to include a 10-pin (single row) and 54-pin (dual row) version. The MicroStac advantage is based on a patented hermaphroditic design, a special design requiring only one part number which enables reduced logistic and inventory costs for board-to-board applications. MicroStac SMT connector series are available from Erntec .
The combination of the MicroStac’s miniature construction and its innovative design makes it suitable for compact and demanding applications. Furthermore, the scope of applications is broad, ranging from sensor technology, medical instruments and mobile communication to automotive electronics, automation engineering, measurement technology, test equipment and building automation. For medical applications, new antistatic versions are now available.
The SMT construction and unique design of the MicroStac allow for economical and automatic assembly. The stability of the miniature connector is facilitated through a tilt-proof contact principle with dual side positioning of the contact on the PCB.
The MicroStac, with its corresponding features of minimal weight (0.18g for the 6-pin design), 100% SMT co-planarity of <0.1mm and suction areas integrated in the insulating body for pick-and-place assembly, is suitable for high-speed manufacturing requirements.
MicroStac products, in spite of their compact construction, can achieve a high current-carrying capacity. The contact is formed through precision stamping, a process which offers a reliable form of contact possible. As a result, the contacts offer an extensive cross-section for low ohmic resistance, while at the same time providing a large radiating surface that yields higher power carrying capabilities.
With an ambient temperature of 20°C and current feed to all contacts, the MicroStac 50-pin connector can transfer 1.6A per contact (in accordance with IEC 60512, test 5b). In summary, the 50-pin MicroStac can safely and reliably carry 80A inside a small footprint.
Within the MicroStac connector family, new versions are now available with 6, 9, 10, 12, and 14 pins (all single-row), and 50 and 54 pins (both two-row). Depending on the connector version, the board-to-board height ranges from 3.0mm to between 5mm to 6.5mm.
Despite the subminiature design, the MicroStac is designed to be used in multiple mated pairs between two boards. Subsequently, when using the MicroStac, there is no need to fear ‘negative tolerance stack up’. The permissible centre offset, when connected, is +/- 0.7mm in the longitudinal direction and +/-0.5mm in the transversal direction. The permissible angular offset is +/-4 degrees.
MicroStac connectors feature a high temperature-resistant insulating body (PA46), and 100% SMT coplanarity to ensure a secure soldering experience. The black isolating body allows simple visual recognition during automatic assembly and, when delivered in the antistatic packaging, the connectors are protected and ready for automatic assembly.
