Block with no sag
This is a product for a heat sink (heat releasing block) used in a module or a circuit; completely free from die sag peculiar to pressed products, securing the same level of precision as cutting but, at the same time, realizing a low cost of pressing. Corner radius 0.05R to 0.1R is nearly acute, and cut surface retains almost 90. This innovative block makes it unnecessary to conduct a checking for defect due to die sag at the time of mounting it to a circuit, eliminating troubles at mounting and improving yield as well.
