Nothing in this document, however, supersedes laws and regulations unless a specific exemption has been obtained.
3. DEFINITIONS
3.1 High Strength Steel. For the purpose of this standard, high strength steel is defined as steel heat treated to 180,000 pounds per square inch (psi) and above.
4. GENERAL REQUIREMENTS
4.1 General. The selective plating process (sometimes called "brush" plating) is the method of depositing metal from concentrated electrolyte solutions or selected areas without immersion tanks. In this process, metal is deposited from an electrolyte held in an absorbent material attached to an inert anode. Plating contact is made by brushing or swabbing the part (cathode) to be plated with electrolyte-bearing anode.
4.1.1 Selective plating uses.
a. To prevent or minimize disassembly costs. b. To minimize machining costs (plate to size). c. To minimize masking costs.
d. To develop field reliability.
e. To plate small areas of extremely large parts. f. To supplement conventional plating
g. To plate high strength steels.
h. To plate onto difficult to plate metals, i.e., Aluminum, Molybdenum, Titanium, etc, either as a bonding agent or for subsequent finishing.
size.
i. To restore worn, corroded, or over-machined parts back to
4.1.2 Printed circuit repairs. Because of the growing demand and limited availability of electronic components, there has been a significant increase in the need for an approved repair process for salvage of damaged or defective printed circuit boards. Techniques have been developed utilizing selective plating for repair of these boards. These techniques are available through the manufacturer of the selective plating solutions. The specific types of repairs that can be accomplished are:
a. Repair of defective plating.
b. Repair of damaged contacts (fingers) due to peeling.
c. Repair of lifted, damaged, or missing pads and traces.
