Abstract:
Disclosed are a test piece and the manufacturing method thereof The test piece includes an insulating substrate and a circuit pattern structure formed on the insulating substrate, wherein circuit pattern structure includes a first metal pattern layer, a second metal pattern layer, a third metal pattern layer, a fourth metal pattern layer, and a fifth metal pattern layer. The first metal pattern layer, the second metal pattern layer, the third metal pattern layer, the fourth metal pattern layer, and the fifth metal pattern layer have same pattern shapes and positions thereof are overlapping in a plane. The first metal pattern layer and the second metal pattern layer are nano-metal films formed by vacuum coating, therefore, the test piece has excellent uniformity of film and low resistance to provide a stable test current to prevent the judging mistakes and to improve the test efficiency.
Abstract:
A wired circuit board includes an insulating layer, and a first conductive pattern and a second conductive pattern formed on the insulating layer. The first conductive pattern includes a first outer terminal on which a metal plating layer is provided, a first inner terminal to be solder connected, and a first wire which connects the first outer terminal and the first inner terminal. The second conductive pattern includes a second outer terminal to be solder connected, a second inner terminal to be solder connected, and a second wire which connects the second outer terminal and the second inner terminal. The first inner terminal and the second inner terminal are arranged in opposed relation with each other so as to be solder connected to the common electric component and preflux processing is performed thereon, and a metal plating layer is provided on the second wire.
