Method and apparatus for carrying circuit assemblies

A method for carrying a circuit assembly with a first side and a second side with a circuit carrier, the method comprising:

• connecting a first plate of the circuit carrier to a second plate of the circuit carrier with a hinge;
• using the first plate to hold a first side of the circuit assembly using a hold-down to interlock the circuit assembly to the first plate in a first mode of operation;
• using the hold-down to release the circuit assembly from the first plate and to interlock the circuit assembly to the second plate in a second mode of operation other than the first mode of operation;
• mating the first plate and the second plate and using a lock to secure the first plate to the second plate in a first state of operation, and to release the second plate from the first plate in a second state of operation that includes interlocking the circuit assembly to the first plate using the hold-down in the first mode of operation and interlocking the circuit assembly to the second plate using the hold-down in the second mode of operation;
• and
• carrying the circuit assembly in the circuit carrier in the first state of operation.
