44 pin QFP socket/44 pin QFP plug

Supported Device/Footprints

These adapters accept 44 pin QFP devices and have a

removable 44 pin QFP solder-down plug. This allows QFP device

to be inserted into and removed from a prototype easily.

The QFP socket accepts packages with the dimension sets listed

below:

Adapter Construction

The adapter is made up of 4 sub-assemblies. They assemble via

connectors making the adapter modular. This way the sub-

assemblies can be replaced easily.

PQFP

The QFP plug will fit most 44 pin. 0.8mm pitch, QFP land

patterns. Usually the pads extend from the body past the tip of

the device leads. This plug will fit on pads that have a minimum

span of 10.0mm or less and a maximum span of 12.0mm or

more.

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.

Inner pad span

10.0mm or less

Outer pad span

12.0mm or more

Adapter Dimensions

Solders to the QFP land pattern on the prototype. Additional QFP

Plugs can be purchased separately.

Adapter Wiring

The adapter is wired 1 to 1. QFP socket pin 1 connects to QFP

plug pin 1. Pin 2 to pin 2 and so on around the package.
