 How to Repair a FPC Membrane Key Switch Panel

Repairing a FPC membrane key switch panel is a simple task that can be done with basic tools. In this article, we will guide you through the process of replacing the membrane and provide insights on the cost-effectiveness of repairing versus buying a new keyboard.

Section 1: Replacing the Membrane
To replace the membrane of the keyboard, follow these steps:

1. Gather the necessary tools: You will need a screwdriver to remove the screws on the back of the keyboard.

2. Remove the screws: Using the screwdriver, carefully remove all the screws on the back of the keyboard.

3. Open the back cover: Once the screws are removed, gently open the back cover of the keyboard.

4. Locate the membrane: Inside the keyboard, you will find the membrane attached to the back cover with pile heads.

5. Disconnect the circuit board: Locate the screw connecting the circuit board to the membrane and remove it. This will allow you to detach the membrane for replacement.

Section 2: Cost Considerations
It is important to note that most membrane keyboards are considered medium to low-grade products with affordable prices. In many cases, the cost of repairing a damaged membrane may outweigh the benefits of buying a new keyboard. Here are some factors to consider:

1. Replacement cost: The price of a new keyboard is often only a few dozen yuan, making it a cost-effective option.

2. Additional expenses: When repairing a keyboard, you need to consider the round-trip shipping cost, as well as the labor and material costs. These expenses can quickly add up and make repairing the keyboard less economical.
Repairing a FPC membrane key switch panel is a straightforward process that requires basic tools. However, due to the relatively low cost of membrane keyboards and the additional expenses involved in repairing them, it is often more cost-effective to purchase a new keyboard. Consider these factors when deciding whether to repair or replace your damaged keyboard.The price mentioned in this article is sourced from the internet and should be used for reference purposes only.

What are the requirements of membrane switches for buttons?

LuphiTouch membrane switch manufacturers analyze from two aspects:

1. For the structure of the membrane switch, the button is a very important part of it. Because the realization of the function of the membrane switch is to rebound by pressing the button, it can also be said that the function of the button is realized by the rebound of the shrapnel, so the membrane switch has requirements for the button.

2. The center point of the installed metal shrapnel must be aligned with the center point of the conductive circuit, and it must be fixed well, otherwise there will be poor contact and no conduction. However, the letters on the key display area on the panel layer are generally abbreviated in order to save space, and the size of the letters is generally no more than twice the size of the metal dome. If it is too large, the balance will be lost, and the precise position of the metal shrapnel will not be found during the operation.

Introduction of key film

Button film, also known as metal dome conductive film.

Metal dome conductive film (Metadomearray), it is a piece of PET sheet containing metal dome (dome), used as a switch on circuit boards such as PCB or FPC, and plays an important tactile type between the user and the instrument. function of the switch. Compared with the traditional silicone keys, the conductive film has a better feel and longer life, and can also indirectly improve the production efficiency of various types of switches using the conductive film.
