The invention discloses a method for testing an in-hole open circuit with a glove. The method includes the steps of wearing the glove, wherein the glove is provided with a detection circuit, the forefinger and the thumb of the glove are respectively provided with electric conduction matter, and the detection circuit is respectively connected with the electric conduction matter on the forefinger and the thumb; enabling the electric conduction matter on the forefinger to be in contact with a top layer circuit of one network hole, enabling the electric conduction matter on the thumb to be in contact with a bottom layer circuit of the network hole, and enabling the top layer circuit, the detection circuit and the bottom layer circuit to be sequentially connected in series; determining that the network hole can be broken over if a detection indication is sent by the detection circuit, or determining the network hole to be the open circuit if the detection indication is not sent by the detection circuit. By means of the technical scheme, the condition of the in-hole open circuit of the network hole in a circuit board can be detected, the process flow can be simplified, and the problem of needle marks can be solved.
Description
technical field [0001] The invention relates to the technical field of circuit board detection, in particular to a method for testing an open circuit in a hole with a glove. Background technique [0002] The circuit board is used as the carrier or motherboard for packaging and welding, ensuring its basic electrical performance is the basis for subsequent processing. In the existing circuit board processing flow, the following processing procedures are usually used for processing. First, the front-end processing of the circuit board is carried out, followed by tinning, drilling (removing the influence of tinned leads), electrical testing (testing open and short circuits), edge (cutting into small pieces and removing tinned leads), and final inspection ( inspection appearance) and packaging. With the development of the electronics industry, the diversification trend of the circuit board structure is becoming more and more obvious. For the tin-plated circuit board, the networ...
