A narrow pitch connector (20) comprising a substrate (22) on which a plurality of first terminal electrodes (30),a plurality of second terminal electrodes (32), and wires (24) electrically connecting the first terminal electrodes (30) with the second terminal electrodes (32) having a function of making conversion from a pitch of the first terminal electrodes (30) to a pitch of the second terminal electrodes (32) are formed, wherein grooves (32A) are formed between the first terminal electrodes (30) respectively.

Description

technical field [0001] The present invention relates to a connector for a narrow pitch, an electrostatic actuator including the connector for a narrow pitch, a piezoelectric actuator, a microcomputer, a liquid crystal panel, an inkjet head using the electrostatic actuator, a piezoelectric actuator, and a Inkjet printers and electronic equipment of these inkjet heads. Background technique [0002] In recent years, the miniaturization and weight reduction of electronic devices has accelerated. Along with this, the demand for miniaturization and cost reduction of components used in electronic devices has been increasing. As a measure corresponding to these demands for miniaturization, a fine processing technique called micromachining has been developed in order to be able to manufacture a microcomputer not only small but also highly functional. As an example of such a microcomputer, there is, for example, a print head (hereinafter referred to as a printer engine unit) that ej...

AI Technical Summary

Problems solved by technology

Moreover, the refinement of connection objects 1 such as the printer engine portion and the LCD unit of the liquid crystal panel has been progressing year by year, and corresponding to this refinement, the interval 10 between the terminal electrodes 3 (refer to Figure 30 ) is narrowed, so even if the position between the terminal electrodes is slightly shifted, the resistance value between the two terminals may increase or the connection may be poor or short-circuited with the adjacent terminal.

[0018] In addition, when the pitch between the terminal electrodes is narrowed and the thickness of the terminal electrodes is thinned for joining, since the space formed between the adjacent terminal electrodes becomes smaller at the time of joining, a short circuit may also occur between the adjacent terminal electrodes.
