INTRODUCTION
International Standard IEC 61076-4-116 establishes specifications and test requirements for a
high-speed two-part connector with integrated shielding function for use as a printed board
connector in industrial environments. The connectors have a primary purpose of serving as a
platform for telecommunications and enterprise computer network equipment. It is expected
that these connectors are going to find applications outside the Telecommunication market,
e.g. in the industrial market, as factory automation, process control, industrial communication,
medical and others.
The connector type was originally developed in the consortium PCI Industrial Computer
Manufacturers Group (whereas PCI is a peripheral component interconnect, which can be
used to connect peripheral components to processors via using a bus structure or serially
connected fabric based transports). This consortium, referred to in short as PICMG has
defined several system specifications describing a backplane connector (fixed connector) in
combination with an edge board connector (free connector) as a functional component of a
specified Plug-in Unit. These specifications are the AdvancedMC.0 and the MicroTCA.0. The
system-description in MicroTCA.0 contains also a test program for the connector. Further
information of PICMG and its specifications can be obtained on the following website:
www.picmg.org.
Based on the connector type and on PICMG-developments, this International Standard was
developed by experts of IEC SC 48B, Connectors. In contrast to the PICMG-standard, the
connector described here has two connector halves (a fixed and a free connector, as shown
in Figure 1). The fixed connector is based on a 1,6 mm ± 10 % plug-in unit printed board
thickness similar to PICMG specifications. In addition, the test program of this IEC Standard
differs from that defined in PICMG based on previous existing tests defined in IEC for
connectors to suit the needs for use in industry. The resulting test schedule differs from the
test-procedures as defined within PICMG to some degree not only in test-severity and
conditions but also in test sequence. Experts within IEC SC48B work together with experts
from PICMG to reach consensus with regard to similarities and differences in the relevant
testprogram. The outcome is intended to be published in separate documents.
A typical arrangement for such a two-part connector is shown in the following outline sketch
(see Figure 1):

Not covered in this International Standard are direct edge connector contacts for printed
boards. The reason for this is, that in difference to the PICMG-specification this International
Standard is intended to define the connector as a component together with test-procedures
only and is not intended to detail functions which are not directly related to the connector
system. Examples for such details are the characteristics of the printed circuit board.
However, based on the information given in 4.5.1 of this Standard contact positioning and
mechanical edge board connector details can be derived. Further information may be
obtained in PICMG-specification AdvancedMC.0. Such direct edge connector contacts are
applied directly to the printed board edge as part of the printed board circuit (free connector)
and form the interface to the backplane (fixed connector), as can be seen in Figure 2.

signal). The function can be defined according to the application

61076-4-116 © IEC:2012 – 11 –
4 General data
NOTE Throughout this specification dimensions are in millimetres.
4.1 Recommended method of mounting
This International Standard specifies free and fixed connectors, suitable for press in
connections to the printed boards. Other terminations techniques, as solder or compression
mount connections are upon agreement between manufacturer and user.
A complete connector consists of two connector halves, a free board connector and a fixed
board connector.
Free board connectors are mounted on the edge of the printed circuit board and have male
contacts with angled press-in terminations, solder terminations or compression mount
termination.
Fixed board connectors are mounted on the backplane and have female contacts with straight
press-in terminations.
The free board connector can be omitted, but then alternatively the printed board used shall
have an edge similar to those of the connection zone as defined in 4.5.1. for the free board
connector. The board connector then is used as a direct edge connector.
4.2 Number of contacts and contact cavities
The number of contacts and their position is fixed and is 170. The number of contacts in the
PCB terminations area might differ when designated ground-pins are combined.
Several contact positions (in total 56) are reserved for ground connections.
The contacts are placed in two different contact rows.
