1. Field of the Invention
The invention relates in general to a detecting device, and more particularly to a detecting device for detecting a package substrate.
2. Description of the Related Art
Please refer to both FIG. 1A and FIG. 1B. FIG. 1A and FIG. 1B are perspectives of a conventional detecting device detecting different package substrates. Conventional detecting device 100 includes several top probes 120 and several bottom probes 130, wherein the top probes 120 and the bottom probes 130 are used for detecting a package substrate 110. The package substrate 110 includes several top pads 112 and several bottom pads 114, wherein the top pads 112 and the bottom pads 114 are electrical connection via several traces 116. The top probes 120 are disposed opposite to the top pads 112 of the package substrate 110, and the bottom probes 130 are disposed opposite to the bottom pads 114 of the package substrate 110.
The detecting device 100 electrically conducts through the top probes 120, the substrate 110 and the bottom probes 130 to detect the substrate 110 whereby the top probes 120 are coupled to the top pads 112 and the bottom probes 130 are coupled to the bottom pads 114, so as to determine whether each of the top pads 112 is electrical connection to each of the bottom pad 114 via a corresponding trace 116. While detecting the package substrate 110′ (as indicated in FIG. 1B) whose densities of the top pads 112′ and the bottom pads 114′ are different than others, the detecting device 100 matching up the package substrate 110′ requires replacing the top probes 120′ and the bottom probes 130′ as indicated in FIG. 1B. As a result, the commonality and convenience of the detecting device 100 is limited, and the detection cost is increased.
