ERNI Electronics have expanded their 0.8mm MicroStac SMT connector series to include a 10 (single row) and 54 pin (dual row) version. The MicroStac SMT connector series, available from ERNTEC , is based on a hermaphroditic design, requiring only one part number which enables reduced logistic and inventory costs for board-to-board applications. The MicroStac’s SMT connector series has a miniature construction and its design makes it suitable for demanding applications.

The MicroStac SMT connector series is suitable for the following applications:

  • sensor technology
  • medical instruments
  • mobile communication to automotive electronics
  • automation engineering
  • measurement technology
  • test equipment and building automation

For medical applications new antistatic versions are now available upon request. The SMT construction and the design of the MicroStac connectors 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. In addition, 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, the MicroStac SMT connector series is suitable for high-speed manufacturing requirements.

MicroStac products 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 cross-section for low ohmic resistance, while at the same time provides 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). The MicroStac 50-pin connector can 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 and 6.5mm. The MicroStac SMT connector series is designed to be used in multiple mated pairs between two boards and can resist ‘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.

The MicroStac SMT connector series feature a high temperature-resistant insulating body (PA46), and SMT coplanarity to ensure a secure soldering experience. The black isolating body allows visual recognition during automatic assembly and, when delivered in the antistatic packaging, the connectors are protected and ready for automatic assembly.
