Adapter Construction

The adapter is made up of 3 sub-assemblies. They assemble via

connectors making the adapter modular. This way the sub-

assemblies can be replaced easily.

The following chart shows the various socket and board part

numbers that make up these adapters.

When disassembling the adapter take care not to bend the pins.

When reassembling the adapter note the pin 1 indicators to align

the parts correctly.

Which adapter is correct for your package

There are several 44QFP packages. Some devices are available

in more that one 44QFP package. Lookup the lead span for the

package you will be using. Find the matching socket in the table

above. Find the adapter that includes that socket in the Adapter

Construction section.

Logical Systems maintains a device to adapter cross reference in

our office and on our web site. Contact us or visit our web site to

look up a manufacturer and device or package code.
