Maintenance Specifications Installation The HP 16442A test fixture is designed for testing electronic devices. You mount the suitable socket module on the HP 16442A, which allows you to easily connect various devices (DUTs) to measurement units. HP 16442A has thirteen channels: 6 source/monitor unit (SMU) channels Up to 3 channels can be connected to SMUs by Kelvin connections.

Inspecting HP 16442A Test Fixture upon Receiving When the HP 16442A arrives at your site, make sure that nothing is missing or damaged. Unpack the carton that contains the HP 16442A, then check the contents against the following figure and table. (For details about furnished and optional accessories, refer to ”Specifications”.)

Installing HP 16442A Test Fixture You can make the HP 16442A stable by installing stabilizers as shown in the following figure. 1. Put a stabilizer on both sides of test fixture. 2. Screw a flathead screw into hole of each stabilizer.
You place the DUT into the provided socket modules in HP 16442A, then measure the dc characteristics by using the connected measurement units.

HP 16442A is equipped with an interlock (Intlk) terminal, which prevents the user from getting an electric shock during operation. If more than 40 V will be forced to HP 16442A, be sure to connect Intlk terminal of HP 16442A to Interlock terminal of measurement instrument using an Interlock/LED cable (HP 16493J option 001 for 1.5 m, HP 16493J option 002 for 3.0 m).

Three universal socket modules and a blank Teflon board module for uniquely shaped devices. 1. Non-Kelvin Connections Use connection cables to connect the FORCE terminals on HP 16442A to the FORCE terminals on the socket module. 2. Kelvin Connections Socket Modules for Power Devices The three socket modules for power devices have separate FORCE and SENSE terminals for Kelvin connections.

Note that hydrochloric acid residue deposited by solder may cause electrical problems. Hewlett-Packard recommends that you solder the wiring on the universal board using low hydrochloric acid solder (HP part number: 8090-0433). Do not use the universal socket module for low-current measurements (less than 1 nA) that require low leakage current.
Performing test Servicing Cleaning HP 16442A Test Fixture To maintain high performance, HP 16442A must be kept clean. Oil, perspiration, hair, dust, and dirt degrade board insulation, which increases leakage current and decreases measurement accuracy. Hewlett-Packard recommends the following cleaning procedure: Chassis, lid, inner plate, and socket modules: 1.

Figure 1-4. Removing the Bottom Cover When wiring the test fixture and socket modules, use low hydrochloric acid solder (HP part number: 8090-0433) to prevent the flux in the solder from spreading unnecessarily. When soldering, make sure the terminals do not make contact with each other. After soldering, make sure that there are no lint bridges so that leakage current is minimal.
