PCB Assembly Manufacturing Process


March 28, 2024

PCB + Components = PCBA

SMT assembly is carried out according to the component types and bit numbers indicated in the designed Gerber File and BOM to produce a complete PCBA.
Assembly of products under the guidance of specialized personnel and with the help of specific tools. There will be a very large number of processes to complete PCB assembly manufacturing, it is also the most popular in the electronics industry and is also the most common type of assembly process.

The printed circuit board will have some designed pads, and the component packages will correspond to each other to achieve the designed function.

After the design is completed, it is decided to use components to be mounted on the designed pads. Simple packages are soldered using an air gun, solder paste, and flux. For more complex ones, such as BGA, the chip needs to be planted in the soldering ball process, Drag over the bottom pad and cleaned with trichloroethylene, then repeat the simple soldering process.

PCB Assembly Manufacturing-Soldering Method

Manual assembly, fully automatic machine assembly, semi-automatic machine assembly.

Manual welding: there are some relatively complex components will be assembled and welded manually, generally in machine welding, to manually weld some of the components that need to be dealt with in the post-process.

Fully automatic machine assembly: All the bit numbers will be set up and the components will be set up in the form of discs in the machine, and then assembled by the machine, to achieve fast and accurate assembly.

Semi-automatic machine assembly: Unlike the fully automatic machine, it needs to be operated by human beings, which is also a more convenient and labor-saving way.

LHD PCB Assembly Manufacturing Advantages and Features

At LHD-TECH, we have our unique management style, which allows us to reduce our costs by about 15-30 percent, saving on equipment wear and tear, energy, and manpower, and reducing the time when components are lost, which is why our SMT assembly services are good and reasonably priced.

Whether it is the maintenance of machinery and equipment, as well as soldering pre-process work used in the management of some of the materials, the use of the latest management system, in the front-end to maximize the elimination of some of the problems that will arise in the assembly.

Supplier management is also one of our major advantages, to the quality of the product, we try our best to meet the priority of quality, so to treat some of the weldings that need to be used in some of the similar to the sol, lubrication, and so on these pre-procedural work of the material, we are to choose the best, as well as the production of the stencil, are made of high-quality materials can be used repeatedly made, so the cost of our stencil in any one of the We only need to pay once for any of our products. This is the result of our belief in the importance of service to our customers and our products.

Why choosing LHD-TECH is the best choice

Because of our strong management system and the concept can let you rest assured, and can bring you a higher level of revenue in the cost of the product, to avoid low-level errors at the same time also be able to bring you more substantial help in the product, coupled with the experience of our staff, the technical ability of the support, can make the product process will only get better and better.

We hope you will choose LHD-TECH and try our excellent service and the most reasonable price.
