HANDLING PRECAUTIONS
MC740-430E
BEFORE OPERATING THE INP HEMT/GaAs MESFET/Si-Bipolar IC MODULES, PLEASE READ
THIS HANDLING INSTRUCTION TO PREVENT DAMAGE FROM ELECTRIC SURGES SUCH AS
POWER LINE LEAK AND ELECTROSTATIC DISCHARGE.
1. Determine the standard GND on the working desk. The Standard GND should be connected to the
highest quality GND in the room.
Connect commonly all of GND terminals of all the equipment to the standard GND on the working
desk. The working desk should be conductive and should be connected to the standard GND.
Connection cables are preferred to be as short as possible and as thick as possible.
2. Put on a conductive wrist–strap connected to the standard GND on the desk through a 1-Mohm
resistor.
3. Confirm that the voltages of all surrounding materials including human body which touch the
modules are less than 0.2 V. Please measure these voltages using an oscilloscope (Do not use
DC and AC voltmeters).
4. Make sure that there is no abnormal spike on the power supply voltage.
5. Ground all soldering iron tips. Leak voltage should be less than 0.2 V.
