Abstract: An upright test apparatus for electronic assemblies includes a case assembly, first motherboard assemblies and a handler. The first motherboard assemblies are disposed in the case assembly. Each first motherboard assembly includes a motherboard, a first main connector, an adapter, a first sub-connector and a central processing unit (CPU). The motherboard is vertically disposed in the case assembly. The first main connector is disposed on the motherboard and electrically connected to the motherboard. The adapter is electrically connected to the first main connector and is substantially perpendicular to the motherboard. The first sub-connector is disposed on the adapter. The CPU is disposed on the motherboard and electrically connected to the motherboard. The handler inserts the electronic assemblies into the first sub-connectors in a vertical direction, respectively, tests the electronic assemblies and removes the electronic assemblies after the electronic assemblies are tested.
