Abstract
Abstract An apparatus and method are disclosed to permit handling an electronic device (20) during programming, development, and other steps. The apparatus include a carrier (2) having a cavity (15) in which the electronic component is immobilized and protected during handling. The carrier cavity can have an opening that permits access to the electronic component. The carrier/device combination is inserted into a socket (35) which includes a plurality of leads (30) with associated contacts for making electrical connection with the electronic component leads (21). The leads of the socket have a footprint identical to that of the electronic component.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
A method for handling a programmable logic device which has a body and a plurality of leads defining a lead footprint, the method comprising: inserting the programmable logic device in a carrier having means for protecting the leads from deformation, and having a cavity to immobilize the programmable logic device; inserting the carrier with the programmable logic device into a first socket having a plurality of contacts arranged within the socket such that electrical contact is made between the contacts and the plurality of leads of the programmable logic device, the first socket having socket leads arranged in the lead footprint of the programmable logic device; performing a first electrical function utilizing the programmable logic device, said step of performing the first electrical function comprises programming the programmable logic device while the carrier with the programmable logic device is in the first socket; removing the programmable logic device and the carrier from the first socket; inserting the programmable logic device and the carrier into a second socket; and performing a second electrical function utilizing the programmable logic device, said step of performing the second electrical function comprises programming the programmable logic device while the carrier with the programmable logic device is in the second socket.
Claim 2
Independent Claim
205 words
A method for handling a programmable logic device which has a body and a plurality of leads defining a lead footprint, the method comprising: inserting the programmable logic device in a carrier having means for protecting the leads from deformation, and having a cavity to immobilize the programmable logic device; inserting the carrier with the programmable logic device into a first socket having a plurality of contacts arranged within the socket such that electrical contact is made between the contacts and the plurality of leads of the programmable logic device, the first socket having socket leads arranged in the lead footprint of the programmable logic device; performing a first electrical function utilizing the programmable logic device, said step of performing the first electrical function comprises programming the programmable logic device while the carrier with the programmable logic device is in the first socket; removing the programmable logic device and the carrier from the first socket; inserting the programmable logic device and the carrier into a second socket; and performing a second electrical function utilizing the programmable logic device, said step of performing the second electrical function comprises programming the programmable logic device while the carrier with the programmable logic device is in the second socket.
Claim 3
Dependent Claim
47 words
The method recited in claim 1 further comprises: removing the programmable logic device and the carrier from either of said first or second socket; erasing the programmable logic device by exposure to ultraviolet radiation; and inserting the programmable logic device and the carrier into a development socket.
Claim 4
Dependent Claim
36 words
The method of claim 2 further comprising a step of testing the functions of the programmable logic device while the carrier with the programmable logic device is inserted in either of said first or second socket.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein one of the first and second sockets has a surface mount design and the other socket has a through-hole design.
