Description
Technical field [0001] The invention relates to the field of circuit board manufacturing, in particular to a flexible circuit board containing a reinforcing sheet. Background technique [0002] The resistance pressure sensing sheet in the mechanical sensor in the prior art needs to pull a lead wire at the end of the sensitive grid of the resistance pressure sensing sheet, and because the lead wire needs to be pulled out of the virtual space, the resistance pressure sensing sheet in the prior art It is difficult to realize the application of changing from a single element to an array and integrating into a surface, that is, it cannot realize multi-touch. Summary of the invention [0003] In view of this, the present invention provides a pressure-sensitive flexible circuit board capable of realizing multi-touch and integrating into a surface and a manufacturing method thereof. [0004] A pressure-sensitive flexible circuit board includes a plurality of resistance pressure-sensitive s...
