development. It is recognized that no single process will work under all customer applications and that customers
will develop their processes to meet their needs. However, FCI cannot guarantee results if these processes vary
from the recommendations.
2.0 SCOPE
This specification provides information and requirements regarding customer application of MetralTM B series
vertical solder to board receptacles.

5.0 APPLICATION INFORMATION
5.1 General Product Information
5.1.1 Location peg information
There are two location pegs on the bottom side of the connector. These pegs perform two functions:
1) They properly locate the connector onto the PCB
2) They serve as a retention feature during the subsequent soldering process
5.1.2 Component masses:
5.1.3 Application forces:
For a vertical receptacle assembly the number location pegs will determine the force required to properly apply the
assembly to the board before soldering. The recommended insertion force for each location peg is 53 N (12 lbf).

• Each 4 row 12mm module contains 24 signal terminals or 8 power terminals.
• Each 5 row 12mm module contains 30 signal terminals or 10 power terminals.
• Signal terminals are located on a 2 mm x 2 mm grid for high signal density.
• 1, 2, 4, and 8 module connectors are standard. Other sizes are available.
• Standard tail lengths include 2.65mm (for use with a 1.6mm nominal thickness PCB), 3.45mm (for use
with a 2.4mm nominal thickness PCB), and 4.25mm (for use with a 3.2mm nominal thickness PCB)
• Terminals may be selectively loaded.
• Available accessories which are end-to-end stackable include guide, keying, DIN power, and Din coax.

5.3 PCB Requirements
The features that are important to define on the printed circuit board when using press fit technology are:
• Drilled hole diameter
• Plated hole diameter
• Plating type in thru hole
• Printed circuit board thickness
• Land/pad size
The recommended values are shown on customer drawing 58531, and a sketch showing these features is shown in
Figure 3.

5.4 Customer Design Considerations
• Receptacles should be placed on 12 mm increments within a slot to be consistent with the preferred module
placement). If 12 mm increments are not possible, receptacles should be placed on multiples of 2 mm within a
slot.
• Keep receptacles a minimum of 4 mm from any edge of the backpanel to avoid handling and shipping damage.
• In applications that require additional components to be mounted from the non-component side, a minimum slot
spacing of 22 mm is preferred to accommodate fixturing.
• The solder tail on the vertical solder to board receptacle is offset relative to the mating contact window. This
offset distance, 0.63 mm, is shown in Fig. 5.
• Refer to Fig. 6 for nominal board-to-board offsets for fully mated vertical receptacles.

5.5 Customer Application Machines (CAMS)
There are no special CAM’s for this product. The required top press tool is simply a “flat rock” tool. Be sure there is
a bottom fixture that allows the tails to protrude through the board while applying the connectors.
5.6 Post-Installation Inspection Criteria
Gap between bottom surface of receptacle housing and top surface of PCB
In order to decrease the risk of interference between mating connector parts during insertion of the circuit board into
the shelf system, it is desirable to not have a gap larger than 0.2mm (.008in) between the bottom surface of the
connector receptacle housing and the top surface of the PCB.
