Abstract: A welding jig and welding process for planar magnetic components are provided. The welding jig includes a fixed piece and an elastic piece. The fixed piece includes a base and a carrier. The base has an opening, bumps at the bottom of the opening and a pair of operation ends extending from the opening. The carrier is fixed on the base and located in the opening, and has multiple through holes. When the bumps are located respectively in the through holes, an accommodation interval is formed between adjacent pairs of the bumps for the placement of the planar magnetic components. The elastic piece is secured to the fixed piece, and when the planar magnetic components are placed in the accommodation intervals of the fixed piece, the elastic piece covers the planar magnetic components and the planar magnetic components abut against two side edges of the elastic piece.

Abstract: A production method of a light guide and a stamper, combining anisotropic etching and isotropic etching. First a plurality of microstructures is formed on a back surface and a front surface of the substrate. By electroforming, rear and front stampers are made from the back and front surfaces of the substrate. Light guides are produced using the rear and front stampers. Anisotropic etching is performed on the front surface of the substrate, forming V-shaped, U-shaped or pyramid like microstructures. Isotropic etching is performed on the back surface of the substrate, forming quadratic, bowl like, oval or semicircular microstructures. If a transparent substrate is used, then after finishing the etching of microstructures, a light source, a reflector, a diffusion sheet and a prism sheet are added, simulating a back light module for performing a test of luminosity, uniformity of light intensity and light emission angle, so that optical properties are known before proceeding with inverse-forming of the stampers.

Abstract: A production method for 3-dimensional microstructures, using a micro-cutting tool with cutting edges for working a surface of a work object and generating a 3-dimensional microstructure that is inverted to the cutting edges of the micro-cutting tool. Production of the micro-cutting tool is performed by generating a photoresist mold of equal shape on a substrate using photolithography, then electroplating in said photoresist mold. After that, the micro-cutting tool is vertically put on the work object, generating the 3-dimensional microstructure on the surface of the work object.
