How Are Motherboards Made

Motherboards are the backbone of any computer and without them, you would not be able to use your device.

They control how data is transferred from one place to another and also manage power distribution which can be very important if something goes wrong.

Motherboards come in all shapes and sizes depending on what you need them for but they generally have a rectangular shape with many holes that connect different parts inside of the board as well as outside pins where other components such as memory cards or hard drives can plug into.

The motherboard is an integral part of any computer so choosing one should not be taken lightly because this will determine what kind of performance your system will have.

What Is A Motherboard?


It is a simple, yet sophisticated machine. The motherboard connects and transmits signals from your peripherals to the rest of your system; be it keyboard or monitor.

These copper tracks on its surface allow for connection between all parts- CPU included!

The motherboard is like an orchestra conductor, bringing together all the different parts in perfect harmony.

On a motherboard, you will typically find standard components such as capacitors and resistors that help regulate electrical current while also managing voltage levels at each individual component with VRMs for more precise control over how much energy moves through your computer’s various hardware organs (CPUs, GPUs).

Some of the Popular motherboard chipsets are:

What Is A Motherboard Made Of?

A motherboard is mainly composed of two materials:

  • Layers of fiberglass for insulation
  • Copper to form conductive pathways

Motherboards are typically made in layers to save space. Stacking 4-8 copper-embedded fiberglass PCBs on top of one another can make them significantly smaller and faster, but it’s important that you never drill through any parts because then your motherboard would be useless!

It’s a good thing that the PCB is pre-drilled before it even arrives at the factory. This helps with mounting holes and through-holes for attaching components, vertical interconnection access (VIAS) which basically means electrical connections between copper layers on top of each other–allowing more flexibility in design than if we had just soldered everything together by hand!

Creating The Base Of A Motherboard

The PCB or printed circuit board is the key component in any electronics assembly.

Layers upon layers of very complicated slices are stuck together with resin to form one solid layer and coated on both sides with copper for maximum conductivity.

A chemical called photoresist forms a trace when exposed by light which etches away at it so that only an image remains – this will be your design!

The UV light cuts through the photoresist to reveal a mask covering specific parts of the copper layer.

The uncovered areas are then washed away, and finally, it’s time for manufacturers who will start manufacturing with this motherboard in mind!

Motherboard Manufacturing Process

The motherboard manufacturing process is essentially broken down into four parts:

1. Surface Mount Technology (SMT)

The process of soldering components onto a motherboard starts with the boards being manually inspected and then placed on an integrated chip tester to ensure that they are accurately marked.

If it passes inspection, its journey continues!

2. DIP (Dual Inline Package)

The procedure for testing a motherboard starts with the placement of small capacitors into an installation machine.

After that, larger components such as 24-pin connectors and input/output ports are mounted manually before passing through a heat chamber said to go all the way up 509° Fahrenheit (265 ° Celsius).

This process ensures correct reinforcement on recently inserted components so they can withstand even higher temperatures during testing!

3. Testing

Testing is a breeze and, as always, important for quality control. All you need to do is tag your I/O ports with an identifying number which will allow the team members in charge of packaging them know when they’re ready!

4. Packaging And Distribution

As a board-builder, you will most likely be sending out your newest designs to manufacturers who are capable of producing them.

To do this effectively takes careful packaging and distribution planning in order for the finished product not only to look good on its way there but also once it arrives at its final destination – whether that’s online or brick & mortar storefronts alike!

Parts Of A Motherboard

Now that you know how a motherboard is made, let’s go over all of the parts.


The CMOS (Complementary Metal Oxide Semi-Conductor) battery is what’s responsible for keeping all the information intact when you shut down your system.

BIOS or Basic Input Output System can be accessed, updated, and modified with ease from within “BIOS” mode on a motherboard which houses this essential function in its circuitry!

2. IDE And SATA Connector (Storage Device Connectors)

If your computer is running slow, make sure the hard drive and storage devices are connected.

Connecting these components will allow for data submission as well retrieval from within the system so check if they’re properly seated before giving up on fixing it all together!

IDE or Integrated Drive Electronics is a 40-pin male connector that connects the HDD.

As technology advanced IDE connectors became obsolete and were eventually phased out in favor of SATA (Serial Advanced Technology Attachment) with 7 pins interface which has 33 fewer pins but faster transfer speeds than its predecessor.

3. Power Connectors

The ATX (Advanced Technology eXtended) connector is the largest type of motherboard plug, and it draws power from a nearby outlet.

The SMPS then uses this to keep your computer running steadily while you’re browsing internet forums or playing games online!

4. Front I/O Connectors

Connect the power switch, LED indicator lights for HDD and USB ports. Make sure you also connect the reset button’s cable here as well!

5. CPU Socket

Your computer’s CPU socket is the heart of your system. It processes and moves data, so it needs to be 100% compatible with a specific motherboard for you want things like email or web browsing to work properly.

6. Expansion Card Slots

The expansion card slots are where you can add extra components such as a video card, network interface, or audio device. The slot is located in the bottom half of your motherboard below an empty bay for installing another processor if needed – so there’s plenty of room!

Video Card Slot

To get the most out of your computer, it is important that you install a dedicated graphics card.

The video card slot lets users boost their graphical performance and enable higher data processing rates with future technology like mortgages or 3D printing applications.

With so many ports available on this type of device for connecting everything from monitors to printers – there’s no wonder why they’re becoming increasingly popular!

  • HDMI
  • DVI
  • DisplayPort
  • USB-C

Network Card Slot

Network cards are what allow you to connect your computer network, whether it’s through LAN or the internet. The slot accepts an RJ-45 port at its back and allows for data transfer between computers on that same local area network (LAN).

Modem Card Slot

This is where you connect your network card so that it can be used to access the internet. This type of connection typically uses an older technology than what we discussed in class, which has two RJ-11 connectors for connecting with telephones and modems alike.

Audio Card Slot

Audio cards are the key to converting electrical signals into sounds we can hear. They come with different ports for various purposes, but usually, there are three 5mm ones: one in front and two on either side of it (for stereo equipment).

  • Microphone
  • Speaker
  • Recorder
  • Gaming Joystick

8. RAM (Memory) Slots

RAM, or random access memory slots is one of the most important parts of a motherboard. The RAM modules that come in these slotted designs allow for fast data transfer and high-speed operations by utilizing their SIMM (Single Inline Memory Module) and DIMMs(Dual inline module).

DDR4 is the new standard for gamers. DDR3 was once king, but with its low bus speeds and high latency it’s been slowly replaced by faster RAM in gaming PCs – though 8GB still seems to be more than enough these days thanks to advances like Enhanced Speed Memory or ESRAM™

However, there’s no clear winner at1 6 Gigs compared to an 8 Gigabyte configuration so if you want to have your cake then make sure both are available!

M.2 SSDs are considered the best storage devices because they transfer data six times faster than standard SATA drives, which makes them perfect for performance-driven computers that need quick access to information.

M.2 stands for ” maternal” as it was designed specifically with small form factor laptops/tablets in mind; however NGF (Next Generation Form Factor) has replaced this name so we’ll refer just to M2 instead of noting all three words each time!

With all the different sections of a motherboard you are likely to interact with during your PC build, it is important not only for these parts but also how they work together.

A chipset acts as an interface between the processor(s), memory (RAM), and other peripheral devices such as graphics cards or network ports. It’s essentially what makes up part one in this three-part system called “The Motherboard.”

Since we’re covering various aspects of building one own personal computer here at AnandTech–to help educate gamers newbies like us become more knowledgeable about computers – let’s take look inside each individual component: Processor chip, Graphics card, etc.

9. M.2 Slot

The northbridge chip is connected directly to the CPU and handles fast communication between it, graphics card, system memory.

It also communicates with less performance-sensitive components such as USB ports or storage devices through a southbridge (communications hub).

The southbridge chip is often found on the motherboard, usually covered by a heatsink that has been engraved with your favorite manufacturer’s logo.

This system can be considered much more responsive and faster than its older counterpart – it also doesn’t have overhead like having all of that northbound data go through one central processing unit (CPU).

Final Words

Now you not only know what a motherboard consists of but when to look for in your next purchase.

Now that we have discussed the manufacturing process and components that make up good motherboards it’s important to learn how they are made so as not to get caught off guard by something bad-quality like some other people before us!
