3. ASSEMBLY INSTRUCTIONS
CAUTION:THE FA5000 CIRCUIT BOARDS ARE SUSCEPTIBLE TO ELECTRO–STATIC
DESTRUCTION (ESD). PRIOR TO HANDLING PWAs, ENSURE PROPER PER-
SONNEL GROUNDING TECHNIQUES ARE USED. INSURE THAT CARDS ARE
PLACED INTO STATIC SHIELDING CONDUCTIVE BAGS WHEN HANDLING OR
STORING.
A. General Assembly Techniques
The Model FA5000 circuit board components are mounted using Surface Mount
Technology (SMT) and also incorporate extensive software programming to function-
ally configure the logic circuits. Thus, Level-3 repair of these circuit boards requires
specialized factory equipment, diagnostic software, training, and techniques; there-
fore, such boards are not field-repairable while the unit is under warranty. Conse-
quently, in accordance with the accepted Level-2 repair philosophy for the FA5000
CVDR, a known defective circuit board assembly shall be returned to the factory for
repair or replacement.
