They assemble via connectors making the adapter modular. This way the subassemblies can be replaced easily. The QFP socket accepts packages with the dimensions listed below: The following chart shows the various socket and board part numbers that make up these adapters.

Some devices are available in more that one 44QFP 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.
