APPLICATIONS INFORMATION

INSTALLATION GUIDELINES

Installing the ADIS16354 requires two steps: mechanical

attachment of the body, followed by the electrical connection.

This device is designed for postsolder reflow installation. It is

not designed to survive the temperatures associated with

normal solder reflow processes.

Mechanical Attachment

The ADIS16354 is designed for simple mechanical attachment.

The open mounting tabs on each side of the body provide

enough room for 2 mm (or 2-56) machine screws. Note that

316 stainless steel and aluminum screws are available for use

in this attachment.

When planning the installation process, the primary trade-off

to consider is the attachment strength advantage of stainless

steel against the nonmagnetic properties of aluminum for systems

that employ magnetic sensors. In addition, the ADIS16354

provides alignment pinholes, one on each side.

Location accuracy of the mating holes may force the use of

a smaller pin. Figure 31 provides a graphical display of the

mechanical attachment, and Figure 32 provides a recommenda-

tion for the physical layout of all the holes required for attaching

the ADIS16354.

Electrical Connections

The electrical interface for the ADIS16354 is a single connector,

which is attached to a flexible circuit extension.

One option for mating connectors can be found in Samtec’s CLM

family. In this case, the part number starts with CLM-112-02.

The flexible circuit has stress relief points to absorb environ-

mental stresses, such as temperature cycling and vibration.

Figure 32 provides the alignment hole locations for designs that

employ the suggested connector mate. This connection is held

by friction only. This figure assumes that the ADIS16354 and

mating connector are on the same surface (plane).

Proper Removal

The flexible circuit interface can tear under excessive force

conditions. An example of excessive force is attempting to

break the electrical connection by pulling on the body of the

ADIS16354, placing all of the stress on the flexible circuit.

The electrical connector must be broken by an appropriate tool,

which is designed to apply even pressure to each side of the

rigid part of the flex cable. The recommended extraction

sequence is to break the mate between the electrical interface,

and then to remove the mechanical attachment hardware.
