One of the major steps taken during the electronic device production process is its assembly, more appropriately termed as PCB assembly. Within the process of PCB assembly, there are two major sub-categories: Full turnkey PCB assembly and Partial turnkey PCB assembly. Focusing on the full turnkey PCB assembly process, this solution involves the procurement of each and every electronic component, order tracking, component management, assembling, inspection and delivery of final product.

On the other hand, partial turnkey PCB assembly is where businesses supply the company with all the components and materials so that they can be assembled in the most effective and professional manner. The Chinese market is concentrated with countless PCB manufacturers and assemblers that offer high-end PCB manufacturing and assembly at low costs. However, finding the best ones can be truly painstaking and scrupulous.

Determining how effective a PCB can be is directly dependent upon how it is assembled. The more specialized and proficient the assembling is, the easier it becomes to install and repair it. Stated below are some basic steps that are involved in the process of full turnkey PCB assembly:

Step#1 - Select a Technology for Assembling

Generally, PCB assembling takes place both, manually and automatically. The two basic methods of PCB assembly are Through-Hole Construction PCB and Surface Mount Construction PCB. The assembler can make use of both the technologies for better results. Once the technology is chosen, the process of PCB assembly is taken forward.

Step#2 – Soldering

There are two basic kinds of solders: lead/tin alloy and lead free. Using any one of the two options, the surface is heated beyond its melting point to allow the solder to freely move around. Make sure only a limited amount of solder is used in order to bond the surfaces. With the completion of this step, you will have all the electric components attached.

Step#3 –Follow the Schematic Pattern

Typically, a circuit board has a schematic pattern. In order to follow the circuit board’s design, utmost precision and focus is required so that even the minutest components are placed in the right position for appropriate functioning.

Step#4 – Place the PCB in the Soldering Device

Then, the printed circuit board is placed in the soldering machine that is designed to sturdily fix all the components on the PCB. This way, the PCB is ready for the next phase of the assembling process.

Step#5 – Testing for Defects

Every PCB passes through a rigorous testing phase, whereby it is tested for any kinds of defects, malfunctions and disorders. This step ensures that the final product is tested for its effectiveness, efficiency and performance before it reaches the customer.
