PCB with Metal Dome

What is dome switch pcb

Metal shrapnel (also known as pot or piece, metal dome, snap dome), made of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (usually high hardness) stainless steel 301 or 304 material. Metal dome is an important part of the snap dome switch PCB.

They are momentary switch contacts that become normally-open tactile metal dome switch when used in conjunction with a printed circuit board (PCB).

PCB is also known as printed circuit boards because it is made by electronic printing. A printed circuit board is a substrate for assembling electronic components and is a printed board on which a point-to-point connection and a printed component are formed on a general-purpose substrate in a predetermined metal core printed circuit board design.

Metal domes can be divided into several groups: round metal dome, triangle metal dome, rectangular metal dome, four-leg metal dome(cross shape), square shape metal dome and other special shapes. PCB membrane switches are widely applicable. It can be applied in areas including mobile phones, diagnostic equipment, industrial controls, test equipment, and measurement equipment, etc.

Applications Of PCB with Metal Dome

CD player

Focusing on three-dimensional assembly characteristics of flexible circuit boards and thin thickness.

The mobile phone

Easy connection of the battery, microphone, and buttons and into one. Focusing on the flexible metal core printed circuit board lightweight and thin thickness. Being able to effectively save the volume of products.

Computer and LCD screen

Using the one-line configuration of thin thickness and flexible circuit boards.

Disk drives

No matter it is or diskette or the hard disk, it is dependent on FPC high softness and thickness of the 0.1 mm slim.

The latest applications

Hard disk drives (HDDs, hard disk drive) of the suspended circuit and the components of xe packaging board, etc.

What we can do in PCB products

We are one of the trustworthy metal dome switch manufacturers and metal dome switch suppliers. However, PCB fabrication assembly is also a very important component for metal dome membrane switch. To meet customers' requests and demands, we have a professional team to help the customers change the PCB circuit into a Polyester printing circuit. There are some designs with space limit which need to be changed from the Polyester circuit or flexible circuit into Double-side or Multi-layer's PCB. That's also one of the services we can provide. In addition, we can provide some PCBA services, such as solder the components and assembling metal dome and different layers' (Overlay, Spacer) in PCB.

As a membrane keypad manufacturer, we will do our best to meet all the needs of customers.

There are a variety of industries that use membrane switch applications. One example would be the medical industry. Membrane switches for the medical industry must comply with strict FDA standards; The membrane switch panel must be reliable, use high-quality metal domes with correct plating, and eliminate crossover on circuits in extreme environments, as people's lives literally depend on them. The custom membrane keypads must be well sealed and moisture protected against liquid spills and cleaning solutions. Some medical professionals prefer their medical devices to have lower tactile force but high tactile feel. This requires good design and proper material selection in order for the latest dome designs to be successful.
