Do motherboards and chassis need copper pillars?

The use of copper pillars is to ensure the electrical connection (grounding) between the motherboard and the case when the motherboard is elevated. Whether to install copper pillars depends on the chassis. Most cases require copper pillars (because of versatility), but some brands use protrusions on the steel plate of the case to support the motherboard to simplify the production process.

#The chassis generally includes a shell, a bracket, various switches and indicator lights on the panel, etc. (Recommended Learning: PHPSTORM )

## Series as part of the computer accessories, its main role is to place and fix the computer accessories, play a support and protection role . In addition, the computer case plays an important role in shielding electromagnetic radiation.

Although it is not a very important configuration in DIY, using a poor-quality chassis can easily short-circuit the motherboard and chassis, making the computer system very unstable.

The chassis generally includes a shell, a bracket, various switches and indicators on the panel, etc. The outer casing is made of a combination of steel plate and plastic, has high hardness, and mainly protects the internal components of the chassis. The bracket is mainly used to fix the motherboard, power supply and various drives.

There are many types of chassis. The most common ones in the market now are AT, ATX, Micro ATX and the latest BTX-AT chassis. The full name should be BaBy AT, which is mainly used in early machines that can only support the installation of AT motherboards.

ATX chassis is currently the most common chassis and supports most types of motherboards. Micro ATX chassis is built on the basis of AT chassis. In order to further save desktop space, it is smaller than ATX chassis.

Each type of chassis can only be installed with the type of motherboard it supports. Generally, they cannot be mixed, and the power supplies are also different. So everyone must pay attention when purchasing.

Computer chassis motherboard is also called mainboard, system board or motherboard; it is divided into two types: commercial motherboard and industrial motherboard.

It is installed in the chassis and is one of the most basic and important components of the microcomputer.

The motherboard is generally a rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are BIOS chips, I/O control chips, keyboard and panel control switch interfaces, indicator light connectors, and expansion slots. , DC power supply connectors and other components for motherboards and plug-in cards.

The motherboard adopts an open structure. Most motherboards have 6-15 expansion slots for the control cards (adapters) of PC peripherals.

By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, allowing manufacturers and users to have greater flexibility in configuring models.

In short, the motherboard plays a pivotal role in the entire microcomputer system. It can be said that the type and grade of the motherboard determine the type and grade of the entire microcomputer system. The performance of the motherboard affects the performance of the entire microcomputer system.

Motherboard (English: Motherboard, Mainboard, Mobo for short); also known as motherboard, system board, logic board, motherboard, backplane, etc., is the center or main circuit board that constitutes complex electronic systems such as electronic computers.
