A solder joint provides electrical, thermal, and mechanical connection throughout product life. Reliability depends on alloy, intermetallic growth, geometry, pad design, assembly conditions, and service stress.

Learn more →Wafer probe testing makes temporary electrical contact to each die before packaging. It screens defects early, supports wafer maps, and provides data for process control and final-test planning.
Learn more →Plasma activation removes weak boundary layers and introduces polar functional groups that improve wetting and adhesion. Bonding should follow treatment within a controlled time because activation can decay.
Learn more →Plasma cleaning uses energetic ions and reactive species to break down organic residue and activate surfaces. The process can reach fine features while limiting liquid chemical use.
Learn more →Bond force, time, and ultrasonic energy must work together to disrupt surface films and create intimate contact. Optimization should find the center of a stable region rather than a single best-looking setting.
