Manufacturing method of keyboard flexible circuit board

Abstract

The invention provides a manufacturing method of a flexible circuit board of a keyboard. The manufacturing method comprises the steps of providing three plastic films used for manufacturing a first flexible circuit board body, a partition board and a second flexible circuit board body; providing silver paste used for printing a first circuit pattern on a first plastic film with the normal technology to manufacture the first flexible circuit board body and manufacturing the partition board with a second plastic film; printing a second circuit pattern on a third plastic film with the silver paste, wherein several areas to be printed with equivalent resistors are reserved on the second circuit pattern; providing electrocondution slurry used for printing the equivalent resistors needed on the areas to be printed with the equivalent resistors on the third plastic film printed with the second circuit pattern and accomplishing the manufacturing of the second flexible circuit board body. According to the manufacturing method of the flexible circuit board of the keyboard, the equivalent resistors are printed by means of the electrocondution slurry and by using the twice printing technology, and therefore the resistance of the equivalent resistors is adjustable and the ghost key phenomenon can be eliminated through the matching of the equivalent resistors and the circuit function.

Description

technical field [0001] The invention relates to the field of computer keyboards, in particular to a method for manufacturing a keyboard flexible circuit board. Background technique [0002] A keyboard is an instruction and data input device used to operate equipment; it also refers to a group of function keys (such as typewriters and computer keyboards) that are arranged to operate a machine or equipment through the system. The keyboard is the most common computer input device, which is widely used in microcomputers and various terminal devices. Computer operators input various instructions and data to the computer through the keyboard to direct the work of the computer. The operation of the computer is output to the monitor, and the operator can easily use the keyboard and monitor to talk to the computer, modify and edit the program, control and observe the operation of the computer. [0003] A keyboard is essentially a collection of key switches. All keys are detected b...

Problems solved by technology

But in many occasions, the combination of more than three keys will be used. At this time, we have to redesign the arrangement of the key matrix for different combinations. Do not put some required combinations in any 2*2 matrix, but will If you change to other button combinations, they will fall into the 2*2 matrix and cannot be used in combination, resulting in limitations in the button combination method, especially inconvenient to use in games
