SECTION III. INSTALLING A CMB
3. INSTALLING A CMB
3.1
Description: This task covers installing a CMB onto a component.
3.2
General Information: The CMB is attached to an assembly or subassembly by one of two methods.
These methods are not interchangeable. The assembly or subassembly will receive only one of the
two methods. The CMB is either permanently affixed to the component by Hysol EA 9394 adhesive,
or a CMB tag is strapped to it. See Table 1 to determine which method is required for a given
assembly/subassembly.
3.3
Initial Setup
Materials:
Acetone (Item 6, Table 2)
Lint-Free Cloth (Item 10, Table 2)
Latex Gloves (Item 7, Table 2)
Identification Tag (Item 5, Table 2)
Contact Memory Button (Item 8, Table 2)
Adhesive, Hysol EA 9394 (Item 2, Table 2)
CMB Mount Adhesive Tape (Item 8, Table 2)
Scotch-BriteTM (Item 3, Table 2)
Emery Paper, 220 Grit (Item 4, Table 2)
CMB Tag Tie (local standard means)
WARNING
Use all chemicals in a well-ventilated area. Refer to the Material Safety Data
Sheet (MSDS) documents for the chemicals for specific safe handling
procedures.
Heat buildup during or after mixing Hysol EA 9394 is normal. However, do
not mix quantities greater than 450 grams, as dangerous heat buildup can
take place, causing uncontrolled decomposition of the mixed adhesive. As
a result, toxic fumes are formed.
Use latex gloves when handling Hysol EA 9394.
CAUTION
Always use latex gloves during installation of CMBs to prevent
contamination from oils and dirt on hands.
Hysol EA 9394 must be mixed well in order for the adhesive to bond
correctly. Mix the adhesive for several minutes until the color and
consistency are uniform.
