Safe Handling of CMOS Integrated Circuit Devices

Many of the integrated circuit devices used in communications equip ment are of the Complementary Metal
Oxide Semicondu c tor (CMOS) type. Beca use of their high open circuit impedance, CMOS integrated
circ uits are vu lnerab le t o damage fr om s tat ic c harges . Care must be taken handling, shipping, and
servicing them and the as semblies in which they are used.

Even though prot ection devices a re pr ovided in C MOS integra ted circ uit inputs, the protect ion is effective
only aga inst over voltage in the hu ndreds of volt s range such as is encountered in an operating s ystem. In a
system, circu i t elements distribute st at i c charg es a n d load the C MOS circuits, d ecreasing th e chan ce of
damage. However, CMOS cir c uits c an be da maged by improper ha ndling of the modules, even in a
system.

To avoid damage t o c ircuits, observe t he following handling, shipping, and s ervicing precautions:

1. Pr ior to a nd while servicing a c ircuit module, part icularly after moving within the service area,

momentarily t ouch bot h hands to a bare metal, earth-grounded surfa c e. This will discharge any stat ic
charge that may ha ve accumulated on the p erson doing the s ervicing.

OTE: Wearing a c onductive wrist strap will minimize static bu ild- up during servicing.

N

2. Whenever possible, avoid tou c hing any electr ic ally conduc tive parts of the circ u i t module with your

hands.

3. Power down the unit b efore inst alling or removing the circ uit module.

4. When servicing a circuit module, avoid carpeted areas, dry environments, and certain types of cl othing

(silk, nylon, etc. ) because they contribu te to st atic build-up. S imilarly, disconnect t he test probe prior
to removing the ground lead.

5. All electric ally power ed test equipment should b e grounded. Apply the ground lead f rom the tes t

equipment to the circ uit module before connecting t he test probe.

6. If a c i rcuit module is removed from t he s ystem, it is desirable to lay it on a c onductive surface (su c h as

a sheet of alu minum foil) which is connect ed t o ground t hrough 100k of resistance.

7. When soldering, be su re the solder ing iron is grounded, and has a grounded tip .

8. Pr ior to connecting jumpers, replac ing c ircuit components , or touching CMOS pins (if this becomes

necessa ry in the r ep lacement of a n integra ted circuit device), be sure to discharge a ny sta tic bu ild- up as
descri bed in procedu re 1. Since voltage differences c an exist across the human body, it is
recommended that only one hand be us ed if it is necess ary to touc h pins on the CMOS device and
associated board wiring.

9. When replacing a CMOS integrated circuit device, leave the device in its c onductive r ail container or

conduct ive foam until it is to be ins erted into the p rinted circuit module.

10. All low impedanc e test equipment (su c h as p ulse genera tors, etc .) shou ld be connected to CMOS device

input s after power is ap p lied to the CMOS circuit ry. Similarl y, suc h low impeda nc e equip ment should
be disconnected before p ower is t urned off.

11. Rep lacement modules ship ped sepa rat ely f rom the fac tory will be p ackaged in a conductive material.

Any modules being transpor ted from one area t o another should b e wrap ped in a similar material
(aluminum foil may b e us ed). Ne ver use non-c onduc tiv e material f or pa c kaging these modules.
