Electrical contact surfaces connection establishing method, involves arranging contact surfaces by irradiating surfaces with laser radiation having power density within specific range

摘要

The method involves arranging contact surfaces (6) by irradiating the surfaces with laser radiation having a power density within the range of 20 kilowatts/centimeter2>. The pulse time and frequency for irradiation of the contact surfaces are within the range of 160 LV, and 4 kilohertz, respectively. The surfaces are scanned at a speed within the range of 200 millimeter/ second and cleaned by laser radiation.
