Technical Introduction: "Improvement of Shape Accuracy (High-Density and Fine Processing Technology)"
Introducing technology for improving shape accuracy! High-precision shape processing tailored to patterns is possible.
At Sato-Sen Co., Ltd., we have achieved a positional accuracy of ±50μm in outline and pattern positioning. For pattern formation, we utilize the LDI (Laser Direct Imaging) method, and for outlines, we can perform high-precision outline processing tailored to the pattern using CCD technology. We improve hole position accuracy with ultra-high-speed micro-diameter drill machines, form high-density circuits (L/S = 30/30) with LDI, and provide high-density multilayer printed circuit boards with stable quality using X-ray reference drilling devices and X-ray length measuring machines. 【Features】 ○ We offer multilayer printed circuit boards → High density, IVH, BVH, and build-up with design flexibility ○ Implementation on through-holes is possible with flat plugs (pad-on-via) ○ Support for narrow pitch patterns with landless through-holes ○ Extremely fine printing is possible (1 character: vertical 0.28mm × horizontal 0.15mm) Please contact us for more details.
