USAGE PRECAUTIONS
Printed circuit board ground lines should with consideration common impedance. Take appropriate static electricity measures. Containers semiconductor materials should have anti-static protection made conductive material. After mounting, printed circuit boards should stored shipped conductive bags containers. Work platforms, tools, instruments should properly grounded. Working personnel should grounded with resistance between body ground. apply negative voltages. negative voltages below -0.3 create parasitic transistors lines, which cause malfunction.
