TION

The RADIALL panel drilling on page 8-27 recommends an additional bore or chamfer machining on the outer edge

of the glass bead housing. This additional machining allows to place a pre-form (solder stick Dia. 0.3 mm) before soldering.

After mounting, solder is ushing and allows the right positionning of the receptacle.

The EMI gasket efciency is guaranteed.

GLASS BEAD

1 Adjust X by cutting the pin if necessary.

2 Introduce the glass bead into its cavity.

3 Place a ring of solder in the groove around the glass bead (a 0.3 mm wire dia. of solder is recommended).

4 Solder the pin (or optional socket) on the PCB trace inside the package.

Beware there is not too much welding.

IMPORTANT: For maximum RF performances, the link track/pin must be as thin as possible.

We advise therefore to follow the A dimension rigorously, by soldering accurately the pin or the socket directly on the trace.

CONNECTOR RECEPTACLE

Place the ”EMI” screening gasket in the groove of the receptacle (if applicable).

Introduce gently the receptacle on the glass bead pin, then screw the ange (use the appropriated tool for screw-in

receptacle).
