M-TEK Assembly: PCB Design, Prototyping and Assembly

What are Printed Circuit Boards (PCB)?


Printed Circuit Boards are fundamentally a board that connects electronic components. PCB assembly is the basic building block of any electronic design. 


Over the year, PCB assembly has developed into a sophisticated and vital component in contract electronic manufacturing. At M-TEK, our team of electronics manufacturers specialise in PCB design, prototyping and PCB assembly. All while offering printed circuit board services including manufacturing and assembly are undertaken by experienced staff that have more than 20 years of experience in PCB designs for companies across the globe.

What is PCB Assembly?

PCB assembly is the process of soldering or attaching electronic components to a printed circuit board (PCB). The board itself is a piece of fibreglass or other substrates upon which copper tracks have been printed. PCB components are either surface-mounted or inserted into holes in the board and then the entire assembly is soldered.


These assembled PCB components are used in a wide variety of electronics. From computers and mobile phones to medical devices and military hardware; there are several advantages depending on the type and industry the printed circuit board is used in. 


The main advantage of PCBs is that they allow for miniaturisation - ie, the ability to pack more components into a smaller space. This makes them ideal for use in portable devices and other high-density applications, such as for medical purposes.



Printed Circuit Boards

A printed circuit board (PCB) is an electronic circuit that is used in a device so it can provide a pathway to its electronic components and mechanical support. PCBs are used in a variety of devices, including laptops and computers, camera, mobile phone and tablets.



In the past, printed circuit boards were constructed through the tough process of point-to-point writing. Completing PCB this way typically led to various failures, including wire junctions and short circuits when wire insulation began to age and crack.




The Layers Of PCB

Did you know that PCB has multiple layers? These layers are:

  • Substrate Layer

    This layer tends to be made from fibreglass and gives the board its firm form. Many boards will use this material for their substrate apart from flexible PCB components. Printed circuit boards tend to be built on flexible plastic such as Kapton. 


    Substrate layers can be made with other materials; however, these can sometimes lack durability which is something you do not want. At M-TEK, our experts have quality materials and resources on hand to ensure durability and high performance for your PCB assembly. 

  • Copper Layer

    These different layers of PCB all depend on how many copper layers they consist of, which are laminated to the printed circuit board using heat. 


    For example, if you are creating a single-sided PCB, the circuit board has one layer of conducting materials on one side of the board and the other side is used for incorporating different electronic PCB components. Whereas double-sided PCBs can mount the conductive copper and components on both sides of the board rather than just one. 


    The double-sided printed circuit boards allow for closer routing traces as they can alternate between the top and bottom layers using vias. How thick the copper layer of your PCB is entirely depends on the power that the PCB needs to withstand. Some PCBs handle a higher power, thus meaning that these particular PCBs will require a thicker copper layer.

  • Soldermask Layer

    The solder mask is then placed on top of the copper layer, which gives the PCB its green colour. This is used to insulate the copper layer and to ensure contact with other metal components is avoided.


    This layer of the printed circuit board is important for the electronic manufacturing process (where the components are soldered onto the PCB), as it helps the user cement it to the right placement. 

  • Silkscreen Layer

    The last layer is the silkscreen layer. This is used for us to help us understand the printed circuit board and the functionality of different pins or LEDs by adding letters, numbers, and symbols.

What is the PCB process?

PCBs, or printed circuit boards, are the foundation of all significant electronics. Nearly every computational electronic gadget, including basic ones like digital clocks and calculators, incorporates these amazing inventions. Each PCB component has a specific function that is determined by the intricate system of copper pathways. 


The printed circuit board process is a complex and detailed manufacturing process that starts with the design of the PCB.

PCB Design - Prototyping

Tested before PCB assembly begins


Our team of PCB electronics manufacturers take the design and creates a prototype. The prototype is sent to an assembler to place all of the electronic components on the printed circuit board.


After the PCB components are in place, it is then tested to make sure the printed circuit boards are working efficiently and effectively. If it does not, further changes will be made and a second prototype created.


Once the board is functional, an actual production board is created and will feature all of the PCB components.


When prototyping has been completed, it is time for PCB assembly to begin. The final step in this process is to install all of the PCB components into your enclosure or housing for use with their intended purpose.



PCB Assembly - Installation

Into enclosure or housing



Our team of electronics manufacturers will place the thin, stainless steel stencil over the printed circuit board. We will apply solder paste evenly across the circuit board. Then, the surface mount technology components are placed on a PCB and soldered onto the circuit board surface. The solder paste needs time to solidify and remain in place to reflow. 


After the surface mount technology components are soldered into place, PCB assembling inspection needs to be undergone. This includes manual checks from our contract electronic manufacturing experts, automatic optical inspections, using an AOI machine and high-powered cameras. We also use X-RAY inspections to ensure a more complex inspection of the printed circuit boards. For more information on our services, click here.


The plated-through-hole (PTH) components need to then be plated through the printed circuit board, by either manually or wave soldering. Once this is complete, our specialists will complete final inspections, product support and simulate tests for the PCB assembly.

Why Use PCB Assembly?

There are a number of reasons why you might choose to use PCB Assembly over other methods of assembling contract electronic manufacturing components. 



  • Miniaturisation

    One of the biggest advantages of PCB assembly is its ability to miniaturise electronic devices. By using a printed circuit board, you can fit more electronic components into a smaller space, which is ideal for portable devices and other high-density applications. 


  • Durability

    PCB assemblies are also made from tough materials like fibreglass or epoxy resin, which makes them resistant to wear and tear. This durability makes them ideal for use in harsh environments or applications where reliability is essential. 


  • Speed

    PCB assembly can often be completed much faster than through traditional methods such as through-hole technology (THT). With proper planning, and hiring a competent PCB assembly company, your printed circuit board can be prototyped, assembled and tested quickly and efficiently.


  • Cost

    PCB assemblies may work out cheaper in the long run as they allow you to reduce costs elsewhere; for example, by reducing man-hours required per device and increasing production speed. 


    Ultimately, though, it depends on what stage of development you're at with your product as well as how many devices need to be made. If you have any questions about our PCB designs and services, feel free to give us a call.
