Remarkable advances in unmanned aerial vehicles (UAV), commonly referred to as drones, have changed the technological landscape. These sophisticated devices have become indispensable tools in various fields including photography, agriculture, disaster management and entertainment. There is one key component behind the seamless operation of these drones – the metal dome. Metal domes are widely used in drones and their peripherals and are revolutionizing the way we interact with these high-tech devices.

Metal Dome Explained

Metal domes, also known as tactile domes or click domes, are small metal components with a round or dome-like shape. They are mainly used as momentary switching contacts in electronic equipment. When pressed, these domes collapse and form electrical connections that register keystrokes or input. The evolution of metal domes from their initial use in remote controls and calculators to their current use in drones reflects the changing needs of technology.

Answers to Common Metal Dome Questions
Customers often ask some questions when making early purchases. After summarizing these problems, today I will introduce to you the common problems of metal domes and what should be paid attention to during the installation of metal domes.

The first is the color of the metal dome: the metal dome is mainly made of stainless steel, with a silver surface. Some customers will need to surface treat the metal dome. The surface of the nickel-plated metal dome is golden yellow. This nickel-plated metal dome can better prevent surface corrosion during use and is more durable. Nickel-plated metal domes feel better in hand and work better than ordinary metal domes.
In addition to the metal dome, the color of the PET glue in the metal dome array has also become a focus of some customers. The PET glues we often use include white, transparent and black, among which white and transparent PET are widely used. However, the actual application still needs to be selected based on the needs of the customer and understand the metal dome array PET.

There will also be some customers who will ask some professional questions, and I will explain them here. Why does the Dome array PET tape lift up during use? In fact, PET is glued to the PCB, and the metal dome array should be flat under normal circumstances. After being used for a period of time, the outline of the dome array may tilt, causing dust to enter the PET, causing undesirable phenomena. So what is the reason for this?


When the dome array has a double-layer structure, the thickness of the upper polyester film is about 0.05mm, and the thickness of the lower spacer layer is about 0.075mm.

If the metal dome is a high-height series, such as a triangular metal dome or a metal dome with legs (height: 0.4-0.7mm), due to the height of the metal dome, the space between the metal dome and the gasket will be too large. Therefore, when the metal dome is close to the outline during use, the dome array in this area will tilt upward. We provide customers with two solution suggestions: The first is to keep the distance between the dome and the contour from being too close based on the actual application, leaving enough space to prevent tilting during use. Alternatively, you can make the shim thicker and add more adhesive to prevent the dome from tilting upward.

What are the benefits of making the dome into a dome array? The metal dome is a small dome in production. A layer of PET tape needs to be attached to the production dome array. First of all, it can prevent dust and contamination from entering, and it can also make the dome more firmly attached to the circuit board.

What is the difference between a Natural Dome and a Nickel Dome
Metal domes make up tiny but often overlooked components of our devices in the world of electronics manufacturing. Metal domes are tiny components, but they play an important role in transmitting instructions. They are key components in various electronic products. Most metal domes are made of stainless steel, and the surface of the stainless steel can be electroplated according to the needs of the product. But have you ever thought about the benefits of nickel plating these tiny wonders? In this article we take a closer look at metal domes and explore the differences between natural domes and nickel domes.

Introduction to natural dome

Metal domes are small components used in a variety of electronic devices, including keyboards, remote controls, and cell phones. They are responsible for providing tactile feedback when pressed, making them an important part of user interface design.

If the metal dome has been used for a long time, will the force affect it?
Metal domes are mainly installed internally, so be sure to check them before installation to avoid causing trouble in subsequent work. The pressing force of the dome is the main performance of the metal dome during use. So will the strength of the dome change over time? Let me introduce to you what the strength of a metal dome is, and what are the strengths of commonly used metal domes? Let’s take a closer look at the strength of metal domes and the factors that affect the strength.

When a metal dome is installed on a product, the strength of the metal dome greatly affects the user’s experience. Therefore, we will design the strength of the dome based on the drawings provided by the customer, and also adjust the strength of the dome based on the actual application. Producing satisfactory products for customers has always been our original intention. Before mass production, we will repeatedly confirm each parameter of the dome, and focus on the quality of the product to ensure customers’ return rate and let customers trust our products.
