Embodiment

[0069] 1. Continuous parallel embodiment. Parallel connection means that the current flows in (outflow) from pad a and pad c, and flows out (inflow) from pad b and pad d. Then all adjacent pads a and pad c must be conductive, and all phases Adjacent pad b and pad d must be conductive, and all four pads are required to be conductive pads. Therefore, it is determined that the A version must be arranged in order to realize the parallel connection. For example, 5 parallel structure, a sequence of placement is:

[0070] A+: A- / A+: A- / A+: A- / A+: A- / A+: A-.

[0071] 2. Continuous series embodiment. The series connection requires that only one corresponding pad is connected between the lower coil on the upper circuit board and the upper coil on the lower circuit board, and the other corresponding pad is insulated from each other. In this embodiment, a certain pad insulation of the upper coil of the circuit board below is adopted, such as a 5-series structure, and a placement sequence i...

Abstract

Flexible printed circuit board and magnetic field coil manufacturing method based on the printed circuit board are disclosed, the method employs a flexible printed circuit board of one structure andthree layouts to realize the series-parallel adjustable magnetic field coils according to different combinations, thus the magnetic field coils with different magnetic field intensities can be conveniently manufactured. At the same time, by changing the number of series-parallel magnetic field coils, the total current demand for magnetic field coils can be changed, and the restriction on the supply current source can be reduced. The implementation of the method first requires a flexible printed circuit board, The circuit board consists of front and back coils, and the projection structure of the two coils is the same. According to the difference of the circuit board pads, the circuit board is divided into three types. The series and parallel combination of the magnetic field coils is realized by different combinations of the three types of circuit boards, so as to realize the magnetic intensity adjustment of the magnetic field coils. The magnetic field coil manufactured by the method provided by the invention has the advantages of regular structure and good consistency. Magnetic field coil magnetic field intensity is adjustable and power supply total current demand is adjustable.

Description

Technical field [0001] The invention relates to the field of magnetic field coil manufacturing, and in particular to a method for manufacturing a magnetic field coil by using a flexible printed circuit board. Background technique [0002] In recent years, with the rapid development of quantum technologies such as atomic clocks, atomic magnetometers, cold atom interference gyroscopes, and nuclear magnetic resonance gyroscopes, related researches have used Helmholtz coils to generate uniform magnetic fields to control the precession of atomic spins and The geomagnetic field is compensated by generating a gradient magnetic field through the anti-Helmholtz coil to cooperate with the optical field for atomic capture and other tasks. The performance and structure requirements of the coil have diversified characteristics, and the importance of a convenient and rapid method for making a magnetic field coil has gradually become prominent. It is difficult to change the parameters of the m...
