Abstract: PURPOSE: A substrate formed moat in is provided to fabricate solder balls of uniform size on the substrate, and a method of forming solder balls using the substrate is provided to prevent generation of contact badness in packaging CONSTITUTION: In a substrate(210) using a solder ball for an external connection terminal, a moat(280) is made by removing a surface layer(240) partially according to some shape centering around a ball pad(232). The moat(280) is desirable to be around 25 micro meter off the ball pad(232) and to be about 25 micro meter in width. The depth of moat(280) also must be as deep as a part of thickness of surface layer(240), for contact badness can happen by being connected with metal wiring(230) formed between a surface layer(240) and an insulator layer(220) in case that the moat is as deep as the thickness of surface layer(240). Because the moat(280) plays a role of forced boundary for a shape of solder ball in a reflow process of a gilded solder on the ball pad, the solder ball(260) is made in uniform size consequently.

Abstract: PURPOSE: A position compensator of an automatic packaging system is provided to freely calibrate a position even while normally operating main power. CONSTITUTION: A mark sensor(101) senses a mark of a wrapping paper. A rotation amount of a pulley of a main power device is detected through a first encoder(102). One mark or plural marks having a regular interval are marked on the wrapping paper. The detected rotation amount is compared with a predetermined reference amount so that an error is detected. When a transportation amount of the wrapping paper under transportation is varied, an error is generated. Thus, with an error amount out of a predetermined error permission limit, compensation control is performed.

Abstract: PURPOSE: A method for controlling a reproducing speed of an optical disk is provided to selectively control the reproducing speed as a low speed only for an error region selection of an inserted optical disk, so as to eliminate a reproducing delay time, and perform a high speed data reproduction. CONSTITUTION: If an optical disk(10) is inserted, a controller(61) rotatably drives the optical disk(10) at an appropriate speed, and generates a recording signal on the optical disk(10). If an error is generated from a reproducing signal, the controller(61) memorizes a current reproduction location of the optical disk(10), and controls a reproducing speed as a low speed in states by using reproducing speed range values of each stage. The controller(61) confirms whether digital data has an error. If so, the controller(61) controls a CIRC decoder(70) to correct the error within a pre-setup frequency, and restores the error data as original normal data. If the error data is not restored, the controller(61) controls the reproducing speed as a next reproducing speed on the basis of the confirmed reproducing speed. If the error data is restored to the original normal data, the controller(61) memorizes a range value of the corresponding reproducing speed. If a pick-up unit(11) is moved from the current reproduction location by the low speed, the controller(61) controls the reproducing speed of the optical disk(10) as the normal reproducing speed(48 speed). If an error is not generated from the reproducing signal, or if data is restored to the original normal data, the controller(61) decides that the moved current reproduction location is a normal region, and decides that a section corresponding to the current reproduction location from a previous memorized location is an error region section, then couples the error region section with the memorized reproducing speed range value to store the coupled error region section and the range value in a RAM(80).
