28. re of the Complementary Metal Oxide Semiconductor CMOS type Because of their high open circuit impedance CMOS integrated circuits are vulnerable to damage from static charges Care must be taken handling shipping and servicing them and the assemblies in which they are used Even though protection devices are provided in CMOS integrated circuit inputs the protection is effective only against overvoltage in the hundreds of volts range such as is encountered in an operating system In a system circuit elements distribute static charges and load the CMOS circuits decreasing the chance of damage However CMOS circuits can be damaged by improper handling of the modules even in a system To avoid damage to circuits observe the following handling shipping and servicing precautions 1 Prior to and while servicing a circuit module particularly after moving within the service area momentarily touch both hands to a bare metal earth grounded surface This will discharge any static charge that may have accumulated on the person doing the servicing NOTE Wearing a conductive wrist strap will minimize static build up during servicing 2 Whenever possible avoid touching any electrically conductive parts of the circuit module with your hands 3 Power down the unit before installing or removing the circuit module 4 When servicing a circuit module avoid carpeted areas dry environments and certain types of clothing silk nylon etc bec
