What are the Trends in Consumer Electronics Assembly?

In addition to many other items you’d find inside an electronics store, the consumer electronics assembly sector is responsible for the manufacture and distribution of different electronic products like TVs, phones, video cameras, stereo equipment, alarm clocks, MP3 players, DVD players and VCRs.

What Does Consumer Electronics Mean?

The production of consumer electronics is a large business with a wide range of participants, some of whom include producers of desktop PCs and laptops.

The “consumer electronics” term refers to a wide variety of electronic devices with features created for end customers to utilize on a regular basis. Brown goods (entertainment or communications items including TVs, smartphones, DVD players, tablets, and printers) as well as white goods make up its two product categories (housekeeping devices such as refrigerators, in-built kitchen systems, and washing machines).

What Does Consumer Electronics Assembly Mean?

Gathering, soldering, as well as integrating electronic parts plus circuits to carry out at least one separate function is the general process of consumer electronics assembly. It is a crucial step in the production of common consumer electronics including computers, phones, toys, engines, and remote controls. This assures that the circuit board, which is seen at the core of all disassembled electrical devices and gadgets, is functional. A PCB is primarily identifiable as a unique green chip covered in copper components and lines.

The SMT board is put together using a variety of methods. The circuit board is originally connected to utilizing a solder screen. Solder paste is frequently applied on component pads. The only components of solder paste are flux and tiny solder grains.

The board is next put through a machine called pick & place, which selects the component out of a dispenser then inserts it in its proper location on the circuit board, after which the application of solder paste is done. A specific soldering device is then used to make sure these components are securely fastened.

Like the created PCB, this assembled PCB undergoes some inspections and tests before being used.

Trends in Consumer Electronics Assembly

Miniaturization of PCBAs

The demand for different consumer electronics like wearables and smart homes has increased; therefore there has been a rise in everything from smart watches which track bodily state to smart gadgets that helps in controlling switches and LED lights. This is why there has been a PCBA miniaturization trend.

High standards for design as well as assembly apply to the Circuit boards used in these products, and high functionality must be maintained while taking into account variables like layout, space size, and weight.

Virtual Reality and Augment Reality Simulation

Technologies like VR and AR are popular, particularly with young people. Also, t hey are utilized in a variety of electronic devices, including games that incorporate augmented reality technology, a VR entertainment area, and the creation of augmented reality smartphones, among others.

Additionally, this has led to the creative invention of electrical devices. To support all the regular operation of such electronics, the production as well as PCB assembly, which serves as the foundation of the electronic devices, also needs to be precisely carried out in line with different international standards.

Advanced Materials

People’s expectations for consumer electronics are constantly rising, and they consistently want better functional experiences from this same electronic gadget, which has a direct impact on the demands placed on consumer electronics PCBs. Manufacturers must incorporate some cutting-edge components when creating completed PCBs in order to meet its versatility requirements, including resin-coated copper, glass fibers, as well as other cutting-edge components. In this approach, a smart watch may support numerous tasks like checking heart rate, establishing a phone connection, and browsing the internet.

Steps in the Consumer Electronics Assembly Process


Stenciling with solder paste:

The first stage in PCB assembly is solder paste stenciling. This step stays the same regardless of the PCB assembly type. Over this board is a stencil fashioned from a metallic and thin sheet. It makes sure that this solder paste will only be used where the mounting of the components is intended. This stencil is removed from this board after the solder paste has been applied.

Components Mounting

Component installation is a pick-and-place task that can be carried either mechanically or through a unique automated system or manually. Component mounting here is done by hand during the thru-hole PCB assembly. The automated machine does it in the surface-mount circuit board assembly. The method of automatically mounting components is quick, accurate, and error-free.


Soldering is used to connect PCB components. Wave soldering is used in through-hole assembly. In this, a hot solder liquid is passed over a PCB with installed components. These solder balls become liquefied as a result, and this paste solidifies after cooling to room temperature. Reflow soldering is done in the SMT PCB assembly, though.

In this, a furnace with a 500°F temperature is used to process the PCB. After melting, this solder paste cools and settles with these components.


To make sure the gadget is operating properly, inspection as well as quality testing were done. It comprises three separate inspection techniques, which are listed below.

  • Manual/Visual Inspection: Only soldered connections can be examined by manual inspection. This technique is only appropriate for small batches of PCBs; else, optical fatigue prevents accuracy.
  • Automatic Optical Inspection (AOI): To inspect PCBs, the AOI device has high-resolution cameras which can be positioned at various angles. For double-sized or single- PCBs, this kind of examination is appropriate, but it is insufficient for multi-layer PCBs that are complex in nature.
  • X-ray inspection: On complex PCB designs featuring multi-layer component type of mounting, X-ray inspections are carried out. It is challenging to optically analyze such intricate PCBs.

Post Assembly Functional Testing & Inspection

After assembly, the PCBs undergo a second inspection and functional testing. To wrap up the process, functionality tests such as the contamination test, micro-sectioning test, and solderability test are conducted.


Our consumer electronics assembly sector is a sizable market with a lot of untapped potential. A vast variety of high-quality products are available to consumers because to inventions, developments, and technical advancements. Through its industrial operations and the jobs it has generated, this industry greatly impacts the whole world economy.
