2-4 Repair Procedures and Techniques — General
3.0 Repair Procedures and Techniques — General
Any rework or repair on Environmentally Preferred Products must be done using the appropriate
lead-free solder wire and lead-free solder paste as stated in the following table:
Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement part
is not locally available, check the parts list for the proper Motorola part number and order the part
from the nearest Motorola Radio Products and Solutions Organization (RPSO) listed in Appendix A
of this manual.
Rigid Circuit Boards
The family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not
accessible, some special considerations are required when soldering and unsoldering components.
The printed through holes may interconnect multiple layers of the printed circuit. Therefore, exercise
care to avoid pulling the plated circuit out of the hole.
When soldering near connector:
• Avoid accidentally getting solder in the connector.
• Be careful not to form solder bridges between the connector pins.
• Examine your work closely for shorts due to solder bridges.
NOTE
Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit
boards — examples shown below) were developed and assembled using environmen-
tally preferred components and solder assembly techniques to comply with the Euro-
pean Union’s Restriction of Hazardous Substances (ROHS) Directive 2002/95/EC
and Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC. To
maintain product compliance and reliability, use only the Motorola specified parts in this
manual.
