We represent a design of a 20 W, fiber-coupled diode laser module based on 26 single emitters at 520 nm.The module can produce more than 20 W output power from
The addition of Cu nanoparticles into the solder pastes by mechanical mixing method creates a positive effect on the microstructure refinement of the LED solder
A big yield drop has been observed during the automatic inspection(AOI) after the saw stage. A step by step AOI inspection check and defect review is made to se
