发明名称 Method for manufacturing a liquid jet recording head and a liquid jet recording head manufactured by such method
摘要 A method for manufacturing a liquid jet recording head is arranged to include the step of connecting, by use of a single point bonder, TAB tapes for supplying electric power with a chip for a liquid jet recording head having, on the central part thereof, an ink supply hole and discharge energy transducing devices for discharging ink. For this method of manufacture, the inner leads of the TAB tapes are connected with the electrode pads on the chip by use of a single point bonding tool having a groove structure formed by two grooves configured to intersect vertically at the tip thereof. With the method of manufacture thus arranged, there is no need for the enhancement of adsorption to fix the chip on the chip stage of an ILB bonder. The fixation is possible with a comparatively weak adsorption in this respect. Hence there is no fear that dust particles or the like in the atmosphere are sucked and adhere to the upper surface of discharge energy transducing devices on the chip. Therefore, an appropriate and reliable electrical connection is possible in good precision, and the production yield of heads is also improved when assembled.
