Problems solved by technology
At present, ordinary bending can no longer meet the existing mobile phone structure, and the mobile phone structure has higher and higher requirements for the bending performance of flexible circuit boards.
In order to meet the different structures of various mobile phones, it is necessary to effectively intercept the poor bending properties. If it cannot be intercepted well, the product will be shipped to the terminal mobile phone factory, resulting in poor product functionality, resulting in the scrapping of the entire module, and a considerable cost loss.
The most important thing is to seriously affect the customer's experience

The invention discloses a flexible printed circuit board fold test fixture comprising a bottom plate, two side plates, a press fit cover plate, a product support plate and a prepressing fixing plate. The two side plates are fixedly arranged on the bottom plate at a set distance, and the product support plate is fixedly arranged between the two side plates; a vertical slide slot is arranged in each side plate close to the front end thereof, a pivot is arranged on each side of the press fit cover plate, the two pivots are arranged in the two slide slots respectively in an up-down sliding manner and can rotate in the slide slots, and the press fit cover plate can be in press fit with the product support plate when sliding to the upper ends of the slide slots to rotate; the prepressing fixing plate can be inserted between the two side plates, pressed on the product support plate and drawn out from the space between the two side plates. The flexible printed circuit board fold test fixture has the advantages the hidden danger after flexible printed circuit boards are bent can be effectively prevented, quality yield and stability are improved significantly, productivity of products is increased, and function poorness of products is lowered.
Description
technical field [0001] The invention relates to a test fixture for a flexible circuit board, in particular to a dead-fold test fixture for a flexible circuit board. Background technique [0002] Flexible circuit board dead-bending refers to the bending of flexible circuit boards (flexible boards or soft-rigid boards), the bending radius R = 0°, and the bending angle is bent clockwise or counterclockwise at 180° and repeated winding tests. With the development of board technology, boards such as mobile phone module soft boards and soft-rigid boards are widely used. At present, ordinary bending can no longer meet the existing mobile phone structure, and the mobile phone structure has higher and higher requirements for the bending performance of flexible circuit boards. In order to meet the different structures of various mobile phones, it is necessary to effectively intercept the poor bending properties. If it cannot be intercepted well, it will cause poor functionality of th...
