PURPOSE:To enable to perform a simultaneous soldering of a coil terminal and a soldering part without the occurrence of a thermal deformation at a guide part, which results in shortening a working time, by a method wherein a plastic guide part in a dot printer head is covered with a ceramic cap. CONSTITUTION:A ceramic cap 10 covers a plastic wire guide part 8 located in a dot printer head 1. This prevents the terminal dformation of the guide part 8, and enables the simultaneous heating of a terminal of a coil 3 and a soldering part of a printer circuit-board 9 by means of a flow solder or an infrared lamp. EFFECT:To enable the automation of infrared soldering and the like. |
