Title: Manufacture of thermal head
Inventor: ENDO TETSUO
IPC: B41J2/345
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a thermal head capable of easily reducing the thickness of a substrate, generating no irregularity of products and imparting excellent printing quality, by forming a groove part having a predetermined depth to the heat generating resistor forming surface of the substrate by cutting and forming a detection resistor so as to cover the wall surface of the groove part and detecting the polishing quantity of the substrate on the basis of the resistance value of the detection resistor. CONSTITUTION:A groove part 2 having an almost V-shaped cross-section is formed to one side surface of a substrate 1 and a detection resistor 5 is formed so as to cover the groove part 2 and circuit patterns 4 are formed and, at the same time, the lead-out part 6 electrically connected to the resistor 5 is formed. The lead-out parts 6a, 6b, 6c, 6d of the lead-out part 6 are constituted so as to be capable of measuring the resistance value of the detection resistor 5. The substrate 1 is polished from the back surface 1b thereof and, when polishing reaches an A-A line, that is, the bottom part of the groove part 2, the leading end part of the resistor 5 begins to be shaved off and the resistance value thereof begins to change. With the advance of polishing, the resistance value of the resistor 5 gradually increases and, at the position of a B-B line, that is, at a place where the detection resistor 5 is divided, the resistance value between the lead-out parts 6a, 6c and that between the lead-out parts 6b, 6d become infinite to show the final point of plane polishing processing.
