    • A solder bonding method and a solder bonding device are provided, in which solder is melted, and heating of electrode portions is performed by irradiating laser light to an inner side of a region where electrodes portions are provided, making the temperature difference between the electrode portions and the melted solder smaller to improve the wettability of the solder and increase bonding reliability. The solder bonding method and the solder bonding device perform bonding of the electrode portions that are formed on an object to be bonded by melting the solder. After supplying the solder onto the electrode portions before melting, a laser is irradiated to the solder and to the electrode portions in the periphery of the solder. The solder melts, and the electrode portions are heated. The wettability of the solder with respect to the electrode portions thus improves, and the reliability of an electrical connection between the electrode portions can be increased.
    • 提供焊料接合方法和焊接接合装置,其中焊料熔化,并且通过向设置有电极部分的区域的内侧照射激光来进行电极部分的加热,使得电极部分之间的温度差 并且熔化的焊料更小以改善焊料的润湿性并增加焊接可靠性。 焊接接合方法和焊接接合装置通过熔化焊料进行形成在待接合物体上的电极部分的接合。 在熔融之前将焊料供应到电极部分之后,激光照射到焊料和焊料周围的电极部分。 焊料熔化,电极部分被加热。 因此焊料相对于电极部的润湿性提高,可以提高电极部之间的电连接的可靠性。

    • A method for acceleration and deceleration control of servomotors always brings out the maximum operating capability of a machine equipped with servomotors, such as a robot, NC machine tool, etc. and accurately moves a respective operating section of the machine, e.g., robot work point, tool, etc., along a commanded path. When a command is read from a program, the speed command value is divided by a maximum allowable (Am) of the machine, set previously, to determine a time constant (T) for acceleration and deceleration control (Step S2), and the time constant is divided by a sampling period to obtain a number (n) of times of commanded speed sampling (Step S3). The servomotor is driven at a controlled speed after the acceleration/deceleration process. The controlled speed is obtained by dividing a sum of a commanded speed of the current sampling period and commanded speeds sampled in the previous (n-1) periods preceding the current period, by the number (n) of times of sampling. Thus, accelerated and decelerated operations of the machine are always performed at the maximum allowable acceleration/deceleration, whereby the maximum operating capability of the machine is available and the respective machine operating section can be moved accurately along the commanded path.
