Surface tension laser cutting
WebThis process is capable of holding quite close tolerances, often to within 0.001 inch (0.025 mm) Part geometry and the mechanical soundness of the machine have much to do with tolerance capabilities. The typical surface finish resulting from laser beam cutting may range from 125 to 250 micro-inches (0.003 mm to 0.006 mm). WebA back surface (1b) of a lead frame (1) has a multiple-irradiated region (1c) which is irradiated with both laser light (L2) scanned in a first scan step and laser light (L3) scanned in a second scan step. A unit resin molding (12) formed in a cutting step includes a corner portion (12t) positioned to overlap the multiple-irradiated region (1c) of the lead frame (1).
