Description

本発明の圧電素子内蔵部品への判別記号の印字方法の実施例の印字対象となる圧電素子内蔵部品（図１（ａ））及び（図１（ｂ））の縦断面図である。It is a longitudinal cross-sectional view of the piezoelectric element built-in component (FIG. 1 (a)) and (FIG. 1 (b)) used as the printing object of the Example of the printing method of the discrimination symbol to the piezoelectric element built-in component of this invention. 図１に示した圧電素子内蔵部品の分解図であって、図２（ａ）は、そのカバー部を、また、図２（ｂ）は、その圧電素子部を、さらに図２（ｃ）は、そのベース部を、それぞれ示す。FIG. 2A is an exploded view of the piezoelectric element built-in component shown in FIG. 1, FIG. 2A shows the cover part, FIG. 2B shows the piezoelectric element part, and FIG. The base parts are respectively shown. 図１に示した圧電素子内蔵部品の斜視図であって、図３（ａ）は、そのカバー部へ判別記号を浮き出し文字で印字した状態を、また、図３（ｂ）は、そのカバー部へ判別記号を抜き文字で印字した状態を、さらに図３（ｃ）は、そのベース部へ判別記号を浮き出し文字で印字した状態を、さらにまた図３（ｄ）は、そのベース部へ判別記号を抜き文字で印字した状態を、それぞれ示す。3A and 3B are perspective views of the piezoelectric element built-in component shown in FIG. 1, in which FIG. 3A shows a state in which a discrimination symbol is printed on the cover portion, and FIG. 3B shows the cover portion. FIG. 3 (c) shows a state in which the discrimination symbol is printed with characters extracted, and FIG. 3 (d) shows a state in which the discrimination symbol is printed on the base portion, and FIG. The state in which the characters are printed with the characters omitted is shown. 本発明の圧電素子内蔵部品への判別記号の印字をウエハ上で複数個まとめて一括して行う状態の平面図である。FIG. 5 is a plan view showing a state where a plurality of discrimination symbols are printed on the wafer in a lump collectively on the piezoelectric element built-in component according to the present invention. 判別記号の水晶振動子への印字をレーザー加工により行う従来例の斜視図である。FIG. 10 is a perspective view of a conventional example in which a discrimination symbol is printed on a crystal resonator by laser processing.
