How to Make Membrane Keyboard Quieter? – A Complete Guide

How to Make Membrane Keyboard Quieter – Membrane keyboard is a keyboard with typical tight keys. The advantage of a membrane keyboard is that the surface of the case is tightly covered without any gaps so that dust, dirt, and other small particles are difficult to enter. The drawback of the membrane keyboard is the lack of typing accuracy, which reduces typing speed. This is caused by the position of the buttons that are almost not far away (attached to each other).

How do Membrane Keyboards Work?

The difference between the workings of a membrane keyboard and a mechanical keyboard is that there are no switches on the membrane keyboard. While the mechanical keyboard has a switch that is attached to each keycaps and is directly connected to the PCB. As for the membrane keyboard, each keycap is right above the membrane switch which is right above the appropriate PCB connector.

All keycaps switches are joined. The membrane sheet is the core of every key function on the membrane keyboard. On a membrane keyboard, you can’t swap switch positions like on a mechanical keyboard. If some membranes are damaged, then all membranes will be damaged.

Common Problems on Membrane Keyboards

A broken membrane is just as uncomfortable as a broken switch. If your membrane is damaged in such a way that some keys get stuck, stuck, or don’t work at all, you will end up with a less than fully functional keyboard. Which is unacceptable whether you are working or playing games, you can’t use a keyboard that doesn’t use all its keys for long periods of time.

The problem that often occurs with the membrane keyboard is that the keys stick together and don’t even work at all. This occurs due to damage to the membrane. As I said before, if the membrane is damaged in a certain button, most likely what happens is that all parts of the membrane will immediately have problems. The indicator is that there will be many buttons that start not working normally.

On a mechanical keyboard if there is a switch malfunction, we still have the option to replace the problematic switch and the keyboard will return to normal function. While on a membrane keyboard, if there is damage to the membrane, it means you have to buy a new keyboard. Fortunately membrane keyboard is not an expensive keyboard, the price is still very affordable.

How Does the Membrane get Damaged?

The membrane is so sturdy, you’d be hard-pressed to do serious damage to it. The most common problem people have is spilling drink on your keyboard or dropping it so the membrane and PCB become slightly misaligned. Sometimes this affects all keys, sometimes only a few.

The problem that most often causes damage to membrane keyboards is water spills that can cause dysfunction on the PCB and the membrane itself. But as I have explained, the membrane has a high level of security for water and dust to enter because of the density of the position of the buttons and the board are almost closed without gaps. There are many membrane keyboards on the market available for waterproof membrane keyboards. The membrane keyboard is also strong enough to withstand impacts. For security, membrane keyboards are much better when compared to mechanical keyboards in general.

Another damage is usage, the more you use and press the keys on the membrane keyboard, the greater the potential damage. The former button press will be clearly engraved on the membrane, this often causes the membrane to break and wear.

How to Fix the Membrane on a membrane Keyboard

Troubleshooting Membrane Keyboard: This section is a very important part for us to do, identify what problems actually occur in the membrane keyboard. This step aims to find the best and right solution to solve the problem with the membrane keyboard. In general, the membrane part of the keyboard that is most often damaged is a thin metal wire that has a function to transfer input to a computer.

Ways to Protect The Membrane:

There are many small things that can be done to protect your keyboard membrane from damage. This should be very easy to do. The main causes that often make the membrane keyboard damaged are dust, small dirt, and water. You also need to buy additional accessories to protect your membrane keyboard. Here are some things to do to take care of your membrane keyboard to avoid damage:

How to Fix the Membrane on a Keyboard: Step By Step

The most effective way to repair the membrane keyboard is to clean the typing marks or pressure marks on each key. This trace is a thin metal wire conductor that has a function to send input to a computer.

  • Take note of the buttons that don’t work.
  • Open the membrane keyboard to access the device inside the keyboard.
  • The screw that has been opened, make sure to put it in the place you have provided so it doesn’t get lost.
  • Start sliding the membrane slowly to release it from the button holder.
  • At the top of the PCB, remove the retaining clip (Pull Gently and Carefully).
  • After the membrane is removed from the PCB, notice the click marks are usually slightly brown.
  • Use Silver Varnish, you will need “Silver Varnish” and a stick (toothpicks can also be used) to spread the varnish.
  • Spread the silver varnish evenly over the spots where the thin metal is visible.
  • Reinstall your membrane keyboard.
  • Do the experiment whether it is working or not.
  • If it still doesn’t work, try again.

How to make membrane keyboard quieter

Noise generated on the membrane keyboard is a common thing. Noise on the membrane keyboard can be overcome in several ways. Here’s how to make the membrane keyboard quieter:

1. Using The Mousepad as The Keyboard Base

Aim to find which button sounds louder. In fact, on a membrane keyboard there are certain keys that sound silent and some that are quite noisy when pressed.

Using a membrane keyboard without a base or mouse pad is one of the causes of noise when used. A good mouse pad can reduce noise on a good keyboard. An XL or XXL sized mousepad is good enough to be used as a membrane keyboard base. You can compare the sound of your membrane keyboard when used with a mouse pad and without a mouse pad. You will definitely feel the difference, it’s quieter when using a mouse pad.

2. Lubricate Keycaps Wall

By lubricating the walls of the keycaps on the membrane of the keyboard, you can minimize the friction between the keycaps and the plastic keycap walls. In addition, by lubricating the walls of the keycaps on the keyboard membrane, you will get a smoother typing experience. You can use switch lubricant or stabilizer lubricant. You can also use dielectric grease, which is easier to find at electronics stores near where you live.

3. Use Damping Foam Into Keycaps

By using dampening foam that is inserted into the keycaps, you will be able to drown out the sound of the keycaps while typing and reduce the resonance space of the sound in the keycaps. Apart from providing good damping, using dampening foam into the keycaps will give you a very smooth typing experience.

4. Lubricating Stabilizer Rod On Keycaps

By lubricating the stabilizer bar on the keyboard membrane keycaps, you can make the keycaps smoother when used for typing. You can lubricate it using Dielectric Grease. If you are confused, you can watch this video tutorial in full.

5. Added O-Ring

Adding an O-ring to the membrane keyboard is effective enough to make it quieter. Oring is usually placed on the keyboard keys to drown out the sound produced when typing. It aims to hit the keyboard membrane plate so as not to make a noisy sound.

Different Between Mechanical vs. Membrane Keyboards

Brief Definition of Mechanical Keyboard and Membrane

The mechanical keyboard is a type of keyboard that was introduced in the early 2000s, the components used in this type of keyboard are switches that are attached to each key. When the user presses the button, it will produce a sound like a tap which indicates a reaction to the switch located at the bottom of each keyboard button.

While the membrane keyboard has a difference in the mechanism that operates with membrane contacts as conduction of electrical circuits at the bottom of the keyboard keys. This difference can be clearly seen in the sound of the beat produced by the keyboard sounds smoother than the hard and tactical mechanical type.

Comparison of Mechanical and Membrane Keyboards

For those who are unfamiliar with computer equipment, of course, it will be difficult to distinguish the type of keyboard, especially the mechanical type from the membrane type. Given the two types of keyboards have a similar physical form. Therefore we also need to know about the differences between the two in more detail through the following explanation.

Physical differences

First, we need to understand the physical differences between the two types of keyboards, this explanation includes discussing the shape, appearance and working system used by each keyboard:

Membrane Keyboards Mechanical Keyboard
Distance between gap buttons
The arrangement of the buttons looks lower and less prominent.
Using a layer of rubber on the circuit of the button.
Produces a smooth sound when pressed.
Requires more power for the keyboard to react immediately.
Distance between meeting keys.
The arrangement of the buttons looks protruding upwards compared to the membrane type.
Using a system of switch mechanisms at the bottom of the button.
Produces a loud sound when pressed.
Button reaction is more tactical even though it is pressed slowly.
