Abstract
A method of making a thermal printhead including a primary substrate and an auxiliary substrate adjacent to the primary substrate. The method comprises the following steps. First, at least one positioning cutout is formed in either one or both of the primary and auxiliary substrates. The positioning cutout is formed at an edge of the selected substrate. Then, the primary and auxiliary substrates are positioned to each other by using a position-adjusting device provided with an upright pin fitted into the positioning cutout. Then, the electrical connection is established between the first and the second substrates via clip pins.
Claims12
A method of making a thermal printhead including first and second substrates spaced from each other, the method comprising the steps of:
- forming at least one positioning cutout at an edge of the first substrate;
- mounting the first substrate onto a first position adjusting chuck member provided with a positioning pin to be fitted into the positioning cutout;
- positioning the first and the second substrates relative to each other;
- and
- establishing electrical connection between the first and second substrates.
A thermal printhead comprising:
- a first substrate provided with a heating resistor;
- a second substrate associated with the first substrate;
- and connecting means bridging between the first and the second substrates;
- wherein at least one positioning cutout is formed at an edge of at least one of the first and the second substrates for facilitating positional adjustment of the first substrate relative to the second substrate.
