Title: Die bonding apparatus
Inventor: FUNATSU KAZUYUKI
IPC: H01L21/58
Filed: 1985-04-10
Abstract: PURPOSE:To improve the positioning of a bonding head irrespective of the accuracy of components by oscillating at 180 deg. an oscillating arms mounted with an actuator guided by a guide of a guide block provided at a bonding arm. CONSTITUTION:A bonding positioning is performed by moving a guide groove block 40 when the second cam follower 15 rotates at 180 deg.. The tangential line A of a trace drawn by a cam followr 5 becomes substantially parallel to the guiding direction B of a guide groove 40 formed on the block 40 immediately before a die collect, not show, becomes the state, as shown, showing the relationship between the followr 15 and the block 40 when a die is mounted on a substrate. Even if the stopping position of the follower 15 is displaced by delta degree due to the fluctuation of a mechanism system and the working error of the component, the error DELTAL of the bonding position becomes L/2.(1-cosdelta) L/2.delta<2>, thereby obtaining considerably good positioning accuracy.

Title: Insulator washing
Inventor: OHATA YASUAKI
IPC: H01B17/52
Filed: 1990-03-26
Abstract: PURPOSE:To reduce the scale of a washing equipment and also effectively prevent lowering of withstand voltage of an insulator due to flowing-down water by connecting a power supply frequency transducer to a motor and draining water while adjusting moving angular velocity of a nozzle so that moving velocity of a flooding point may have an almost fixed value. CONSTITUTION:A nozzle 7 is turned in the axial direction of an insulator 1 from tower position to upper position by a driving power supply 6 to discharge jet stream for washing, but moving velocity at a pouring point on the insulator 1 of jet hydrogen operates at fixed angular velocity in the region of a distance between pouring point and the nozzle to be nearly shortest, and when region is missed and (a) in case the pouring point goes away from that region, operation is carried out at a rectilineally reducing velocity, (b) in case the pouring point comes close to the region, operation is carried out at a rectilineally increasing velocity. Thereby, a pouring amount per unit time on the insulator can be reduced thus enabling a material quantity required for the equipment to be cut and to effectively prevent lowering withstand voltage due to running down water and also to heighten withstand voltage at an active-line washing time.
