Description

Electrical measurement jig for rigid-flex board Technical Field The utility model relates to the technical field of electronics, in particular to an electrical measurement jig for a rigid-flex board. Background Because of the dress subsides of supporting electronic components, often design to the hard board structure for the circuit board that car light was used, and the hard board can't realize three-dimensional bending, and when car light module function was many, installation space is little, when needs bending, often can select flexible circuit board to add aluminium stiffening plate, realizes bending and heat conduction, but the cost of flexible circuit board is generally higher than the hard board and is approximately 30-40%. Therefore, flexible rigid-flex boards have been developed. However, the conventional electrical testing fixture can only solve the problems of open circuit and short circuit of point-to-point measuring lines in a complete network. The logical relationship between two independent networks cannot be measured. The soft and hard combined board is a special structure, is a product formed by combining two boards (two independent networks), cannot completely ensure the communication performance of the networks, and can realize the connection of the two networks only by a medium (solder paste). After the network conduction between the soft board and the soft board bonding pad of the hard board is realized by brushing solder paste on the corresponding area, the electrical measurement can be performed. Before the solder paste is brushed, the network of the soft and hard plates is not conducted, and whether the network relationship between the soft and hard plates is normal cannot be measured. To solve the above problems, we have made a series of improvements.
