Abstract

PURPOSE:To realize an easy and assured cut of an IC pattern without impairing the characteristics of the circuit, by deleting the conduction part of the through-hole which gives a connection between the upper and lower face conduction patterns of the substrate. CONSTITUTION:The upper face conduction pattern 3b and the lower face conduction pattern 3e of the 2-sided printed circuit board 1 are connected to each other via the conduction part 4a of the through-hole 4. Thus an IC pattern is formed. In such constitution, the cut of the IC pattern can be done easily and assuredly by cutting off the part 4a and others, thus eliminating the blanking work of the board 1 itself. As a result, the distortion due to the blanking can be prevented to give no impairment to the circuit characteristcs. Accordingly, the control or the like of the oscillation frequency can be performed easily and assuredly by cutting off the prescribed divided stage pattern.
