Service life
Service life describes the duration of use of a Contact Probe or a contact component before wear, contamination, or electrical contact problems necessitate replacement. It thus indicates how long a Contact Probe can be used reliably under defined test conditions.
In printed circuit board testing, service life is influenced by factors such as the contact point, surface finish, flux residues, oxide layers, Spring force, tip style, and coating. Robust contact tips and stable contact are particularly crucial for contaminated solder joints or lead-free solder joints.
For Contact Probes in the Progressive Series, service life is enhanced by the combination of Progressive Coating, increased spring preload, and suitable Tip styles. This allows for better simulation of demanding contact conditions in ICT and Functional Test.
FAQ
Service life depends on contact force, tip style, coating, Test Point, contamination, surface material, and the specific test conditions.
Flux residues, oxide layers, or dust can put greater stress on the contact tip and reduce the service life of a Contact Probe.
The Progressive Series combines progressive coating, increased spring preload, and appropriate Tip styles to make Contact Probes more durable under challenging test conditions.
