Abstract
A detecting structure formed on the space of circuit unit correctly and easily detects whether the lines of the circuit unit are formed on the correct position, and more particularly to obtain the deviation difference of a position provided to form the lines. The detecting structure is able to be formed on a space of periphery of each circuit unit, thus the detecting result is exactly correct.

A detecting structure formed on a PCB to detect unavailable lines, wherein the PCB having at least one base board, multiple circuit units having multiple lines formed on the base board and at least one detecting line structure formed on the base board, and the detecting structure comprising:
- a detecting line formed on a bottom surface of the base board and multiple different diameter windows defined on the detecting line;
- multiple probes formed in the base board, the multiple probes respectively corresponding to one of the windows of the detecting line, wherein in a normal state, the probes respectively disconnects from the detecting line;
- and
- multiple pads formed on an upper surface of the base board and which respectively connected to one of the probes;
- wherein
- detecting unavailable lines of the PCB is to check whether the probes are electrically connected with the pads and the detecting line.
