[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed circuit boards or printed circuit boards. The English names are (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit boards (FPC circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as substrates. They are highly reliable and extremely flexible printed circuit boards. They have the characteristics of high wiring density, light weight, thin thickness, and good bending properties.) and reechas, Soft and hard combination plates - the birth and development of FPC and PCB have given rise to a new product, the soft and hard combination board. Therefore, a rigid-flex board is a circuit board with both FPC and PCB characteristics formed by combining a flexible circuit board and a rigid circuit board through lamination and other processes according to relevant process requirements.

[0003] A blind hole is a conductive hole that connects the surface layer and the inner layer but does not penetrate the entire board. The blind hole is located on the top and bottom surfaces of the circuit board and has a certain depth. It is used to connect the surface circuit and the inner circuit below. The depth of the hole usually does not exceed a certain ratio. Blind hole detection is to insert the detection convex plug into the upper and lower blind holes of the circuit board, and detect whether the circuit board is operating normally after power is turned on, or whether the conductor property of the blind hole and the diameter of the blind hole meet the requirements. Since the position of the circuit board to be detected is prone to deviation during detection, the plug of the blind hole is misaligned during detection, affecting the accuracy of the circuit board detection results.
