Electrostatically Sensitive (ES) Devices

Some semiconductor (solid-state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect

transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of

component damage caused by static by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any

electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available

discharging wrist strap device, which should be removed to prevent potential shock reasons prior to applying power to the unit

under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as

aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static type solder removal device. Some solder removal devices not classified as "anti-static" can

generate electrical charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it.

(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or

comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective

material to the chassis or circuit assembly into which the device will be installed.

CAUTION

CAUTION

CAUTION

CAUTION : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the

brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient

to damage an ES device.)

General Soldering

1. Use a grounded-tip, low-wattage soldering iron and appropriate tip size and shape that will maintain tip temperature within

the range or 500 ° F to 600 °

2. Use an appropriate gauge of RMA resin-core solder composed of 60 parts tin/40 parts lead.

3. Keep the soldering iron tip clean and well tinned.

4. Thoroughly clean the surfaces to be soldered. Use a mall wire-bristle (0.5 inch, or 1.25cm) brush with a metal handle.

Do not use freon-propelled spray-on cleaners.

5. Use the following unsoldering technique

a. Allow the soldering iron tip to reach normal temperature. (500 ° F to 600 ° F)

b. Heat the component lead until the solder melts.

c. Quickly draw the melted solder with an anti-static, suction-type solder removal device or with solder braid.

CAUTION

CAUTION

CAUTION : Work quickly to avoid overheating the circuit board printed foil.

6. Use the following soldering technique.

a. Allow the soldering iron tip to reach a normal temperature (500 ° F to 600 ° F)

b. First, hold the soldering iron tip and solder the strand against the component lead until the solder melts.

c. Quickly move the soldering iron tip to the junction of the component lead and the printed circuit foil, and hold it there only

until the solder flows onto and around both the component lead and the foil.

CAUTION

CAUTION : Work quickly to avoid overheating the circuit board printed foil.

Some chassis circuit boards have slotted holes (oblong) through which the IC leads are inserted and then bent flat against the

circuit foil. When holes are the slotted type, the following technique should be used to remove and replace the IC. When working

with boards using the familiar round hole, use the standard technique as outlined in paragraphs 5 and 6 above.

Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit

board causing the foil to separate from or "lift-off" the board. The following guidelines and procedures should be followed

To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern

side of the circuit board. (Use this technique only on IC connections).

1. Carefully remove the damaged copper pattern with a sharp knife. (Remove only as much copper as absolutely necessary).

2. carefully scratch away the solder resist and acrylic coating (if used) from the end of the remaining copper pattern.

3. Bend a small "U" in one end of a small gauge jumper wire and carefully crimp it around the IC pin. Solder the IC connection.

4. Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good
