Wiring structure of sample detection pore plate, and sample detection pore plate

Abstract

The invention provides a wiring structure of a sample detection pore plate, and the sample detection pore plate. The sample detection pore plate is provided with a substrate, a plurality of detectionelectrodes are disposed on the surface side of the substrate, each of the plurality of detection electrodes comprises a working electrode to which a voltage is applied and an opposite electrode for detecting and outputting a detection signal, the wiring structure comprises a power supply wiring for supplying power to the working electrode and a signal wiring for outputting the detection signal ofthe opposite electrode, and each of the power supply wiring and the signal wiring comprises a surface wiring portion disposed on the surface of the substrate, a back surface wiring portion disposed onthe back surface of the substrate, and a wiring penetrating portion for penetrating through the substrate and connecting the surface wiring portion with the back surface wiring portion. The wiring structure provided by the invention can reduce the wiring length on the surface side of the substrate, reduce the wiring density and improve the degree of freedom in the wiring design on the surface side and the back surface side of the substrate.

Description

Contents of the invention [0001] The invention relates to a wiring structure of a sample detection hole plate and a sample detection hole plate. Background technique [0002] In the field of biological sample detection, especially in the liquid biopsy detection field, a sample detection device is usually used to detect biological samples. The sample detection device includes: a housing, which is divided into a bottom case and a cover plate; a holding structure, which has a holder arranged in the bottom case of the above-mentioned case, and a pressurizer arranged on the cover plate of the above-mentioned case; sample detection an orifice plate, which is used to contain biological samples, has a box shape, is placed in the accommodating portion of the above-mentioned holder, and is pressurized by the above-mentioned pressurizer to be held by the above-mentioned holding structure; and a probe module, which has The probe is connected to the detection electrode of the sample det...

Problems solved by technology

If the line width of the wires 111 and 112 is reduced, not only the difficulty of the process will increase and the cost will increase, but also the resistance of the wires will increase and the wires will be easily broken.

In addition, it is necessary to arrange circuit boards 110 at the edges on both sides of the back of the base substrate 101, resulting in a large number of components, and the wiring needs to be electrically connected across the base substrate 101 and the circuit board 110, and the process is complicated.
