Title: Method and apparatus for inspecting electronic part mounting state
Inventor: HATA SEIJI
IPC: G01B11/245
Filed: 1989-02-28
Abstract: PURPOSE:To detect a lead state without being affected by the distortion of a substrate itself and an adjacent lead row by projecting slit light on the lead row almost vertically and detecting the profile of the slit light in an oblique direction crossing the lead row at a right angle. CONSTITUTION:Slit light is projected on the lead row arranged on a substrate 9 from a slit projector 2 in the direction vertical to the surface of the substrate 9 and the state of the lead row is imaged by two TV cameras I, II in the direction of an angle theta of 45 - 60 deg. to the surface of the substrate so as to hold the slit light between said cameras. At this time, when the slit light is projected on the leading ends of leads, the leading ends of the leads shine like (a) to be detected. When the slit light is projected on the sides reverse to the TV cameras so as to hold the leads between the cameras, the cutting of the slit light due to the leads is detected like (b). When there is no leads, the profile of the slit light becomes linear. These data obtained by the two TV cameras are combined to judge the presence of the leads.

Abstract: PURPOSE:To achieve improvement of quality and reduction of manufacturing cost by a method wherein a thermal energy generating amount in recording is equalized at a plurality of thermal acting parts by varying a structure itself of a resistor and or a protective layer, and its shape or thickness according to its existing position. CONSTITUTION:In the case where heat resistance at both ends of a thermal resistant layer is 15OMEGA/Square and heat resistance at a central part is 20OMEGA/Square in an A4 width fullmulti unitary type ink jet recording head, a size of a central part heater is designed to be 20mumX100mum, and a size of heaters at both ends is designed to be 17mumX15mum. When thus designed, resistant values become 20X100/20=100OMEGA at the central part and 15X115/17=101OMEGA at both end parts, and both become almost equal. Since uniformity of a discharge volume has much to do with a printing characteristic (quality herein, if an area of the heater is equalized over the whole, the heaters at the central part and both end parts become to have the same resistant value. Therefore, foaming voltage becomes the same at any segment.
