Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, specifically to a signal transmission stable flexible circuit board. Background Technology

[0002] After the flexible circuit board is assembled on the substrate, there are two situations depending on the main connection line and the secondary connection line between the two assembly points on the substrate: the secondary connection line is larger than the main connection line or the secondary connection line is equal to the main connection line. The former will cause the circuit board to bend and stack.

[0003] When the external device moves, it causes the circuit board to move as well. This causes the bent and stacked parts of the circuit board to shake continuously, which in turn affects the high-frequency signal output of the circuit board. The circuit boards are stacked in a disordered manner and come into contact with each other. When they shake, the friction causes wear on the circuit components on the circuit board.
