80 SMT007 MAGAZINE I APRIL 2024 Furthermore, the standard SAE AS22759 Rev D. covers insulated single conductor electri- cal wires made with tin-coated, silver-coated, or nickel-coated copper/copper alloy conduc- tors 8 . is standard has 196 detailed specifica- tions that describe variations of wires accord- ing to the insulation type, the coating type, and the type of copper material. Contacts Contacts, also known as terminals, are components that terminate a conduc- tor (i.e. wire) that is to be affixed to a wire or a cable to establish an electrical c o n n e c t i o 3 . F i g u r e 5 shows the components of a typical machined con- tact, which comprise a w i r e b a r r e l , s h o u l d e r / locking ring, and the con- tact area. e wire barrel is where the crimping will take place. ese contacts fully contain the end of the wire, preventing conduc- tor strands from becoming loose over time. Examples of machined contacts are shown in Figure 6. Sta m p e d a n d f o r m e d c o n t a c t s a r e i n e x p e n - sive to manufacture, and oen are configured on reels for high volume manufacturing facili- ties. ese contacts are cost-effective, read- ily available for any manufacturer, and very common across all electronics manufactur- ing industries. However, the end of the con- ductor strands, also known as the wire brush, remain exposed aer crimping as shown in Figure 5: Components of a machined contact. Figure 6: Examples of machined contacts.
