Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a flexible circuit board. Background Art

[0002] At present, most monitors are touch screen compatible. When the touch screen flexible circuit board or the display flexible circuit board (i.e., the main flexible circuit board) is connected to the whole machine, there are two connection methods to choose from: one is to connect to the whole machine motherboard separately, which requires two interfaces to be reserved on the whole machine motherboard; the other is to first connect the touch screen flexible circuit board with the main flexible circuit board, so that only one interface needs to be reserved on the whole machine motherboard. The second connection method is currently popular in the market.

[0003] However, when the touch screen flexible circuit board is first connected to the main flexible circuit board, a zero insertion force connector is usually used. However, this connection method has the following three problems: high cost, supply chain problems, and assembly tolerances. The buckle connection method requires a margin; this not only takes up a certain amount of space, but may also cause the flexible circuit board to bulge.

[0004] Therefore, a flexible circuit board is urgently needed. Utility Model Content
