Abstract
Description
technical field
[0001] The invention relates to a structural design of a flexible printed circuit board, in particular to a structural design in which grooves are provided in the bending area of the flexible printed circuit board to form bending stress lines. Background technique
[0002] The main characteristics and advantages of flexible printed circuit boards (FPC) are easy to bend and flexibility. Therefore, flexible printed circuit boards are often used in design structures that need to be flexed during assembly. It is very important that the location is accurate.
[0003] see figure 1 and figure 2 As shown, in the prior art, a white paint line 11 is generally added at the bending position of the flexible printed circuit board 10, so that the operator can identify the bending position. However, in this conventional bending method, due to the printing tolerance of the white paint line 11 and the tolerance caused by the operator's manual bending, it is often impossi...
