Patent DE-3015683-A1 (DE)
Inventor: TAKASHIMA KAZUTOSHI
IPC: B23K20/00
Filed: 1980-04-23
Abstract: A method of wire-bonding comprises a first step (Fig. 3) of bonding the wire to a selected one of the electrodes of a semiconductor chip on a ceramic package and to a lead to be connected to the selected electrode. During this, the distance Dal from the highest starting position or home position A of an ultrasonic wedge bonding tool to the selected electrode and the corresponding distance Dfm to the corresponding lead are measured and stored. When bonding the remaining electrodes and leads, the speed and range of each movement of the tool is based on the measured distances to provide a desired motion of the tool (Fig. 4(a)). In particular, the tool is moved slowly into contact with the electrode or lead, as shown at C, only in ranges +/-  DELTA  alpha  and +/-  DELTA  beta  about the determined distances Dal and Dfm. With this method, it is possible to increase the speed of the bonding process because the times T1' and T2' for which the tool is moving slowly are less than the times T1 and T2 which would otherwise be taken. The quantities  DELTA  alpha and  DELTA  beta  are based upon statistical determinations of the accuracy of manufacture of the components. A wire-bonder for performing this method is also disclosed and includes a memory store for controlling the rotational speeds and angles of a cam for effecting the requisite tool movements. <IMAGE>

IPC: B67C3/00
Filed: 1980-06-21
Abstract: The valve, which is operated by the flow of liquid, has a body (11) with an opening for the end of a supply tube (12) at right angles to the opening containing the discharge (13). Liquid entering the supply tube pushes a ball (14) down against the force of a spring (15) resting on top of the discharge tube. The supply tube has its inner end sloping at an angle so that, when rotated about its axis, no liquid can be discharged towards the ball below. This action can be used to close the valve when cleaning fluid is being used. The supply tube has a flange around it, with a flat across it, adjacent to which is a locking screw (17) which must first be released to allow the tube to be rotated into the blocking position.
