What is Multilayer PCB Assembly One-stop Service?

Multilayer PCB assembly one-stop service means that multilayer PCB assembly manufacturers provide services such as electronic component procurement, PCB procurement, SMT patch processing, DIP plug-in processing, and multilayer PCB assembly testing. Customers only need to provide complete information (such as PCB files, BOM sheets, coordinate files, mounting files, etc.), and then they can wait for the delivery. This is a relatively popular electronic processing mode nowadays, and it is loved by more and more customers. The one-stop processing mode of multilayer PCB assembly can save the tedious work of component procurement and PCB production.

Multilayer PCB Assembly One-stop Precautions

1. Circuit design

For multilayer PCB assembly, good circuit design is the foundation of success, and it is most basic to carry out circuit design according to the actual needs of the product. However, some engineers forget to consider the actual processing difficulty in the process of circuit design. Boards with the same function must pay different processing costs due to different processing difficulties, and some problems that hinder processing efficiency and actual performance will also be encountered during processing.

2. Selection of materials

Material is one of the key factors to ensure quality. The selection of materials is very important to produce a high-quality PCB board. The process and materials of PCB production can be directly requested. The procurement of multilayer PCB assembly components can provide standards and price ranges. Important components can also be. You can directly specify the supplier's product brand. The quality of high-quality components is difficult to buy at the price of inferior products. The need to control costs also needs to communicate with the procurement staff of the multilayer PCB assembly factory. How to reduce costs while ensuring the quality of product plans is also a technology.

Influencing Factors of Multilayer PCB Assembly Preservation

1. The environment

The humid and dusty environment is obviously not conducive to the preservation of multilayer PCB assembly. These factors will accelerate the oxidation and fouling of the multilayer PCB assembly and shorten the shelf life of the multilayer PCB assembly. Generally, it is recommended to store the multilayer PCB assembly in a dry, dust-free environment with a constant temperature of 25°C.

2. Reliability of components

The reliability of components on different multilayer PCB assemblies also determines the shelf life of multilayer PCB assemblies to a large extent. Components using high-quality materials and processes have the ability to resist harsh environments. It has a wider range of capabilities and oxidation resistance. Stronger, which also provides a guarantee for the stability of the multilayer PCB assembly.

3. Material and surface treatment process of printed circuit board

The printed circuit board material itself is not easily affected by the environment, but its surface treatment process is greatly affected by air oxidation. Good surface treatment can prolong the shelf life of multilayer PCB assembly.

4. Multilayer PCB assembly board running load

The workload of a multilayer PCB assembly is the most important factor in its shelf life. High-frequency and high-load operation will produce continuous high impact on the circuits and components of the circuit board, and it is easier to oxidize under the influence of heating, resulting in short circuit and open circuit during long-term operation. Therefore, the working parameters of the multilayer PCB assembly should be in the middle range of the components and avoid approaching the peak value, so as to effectively protect the multilayer PCB assembly and prolong its storage life.       

Packaging Requirements for Multilayer PCB Assembly

Packaging requirements and precautions for multilayer PCB assembly. After the multilayer PCB assembly completes all processing procedures, in order to ensure that the multilayer PCB assembly board delivered to the customer is in a complete and good condition, special packaging is required before delivery to prevent damage during transportation.

After the multilayer PCB assembly is produced, we need to transport the multilayer PCB assembly to the customer in various ways. During transportation, we need to pay attention to the following requirements.

1. Packaging materials

The multilayer PCB assembly is a relatively fragile and easily damaged product. Before transportation, it must be carefully packed with bubble bags, pearl cotton, electrostatic bags, and vacuum bags.

2. Anti-static packaging

Static electricity will break down the chips in the multilayer PCB assembly board. Since static electricity is invisible, intangible, and easy to generate, anti-static packaging must be used during packaging and transportation.

3. Moisture-proof packaging

Before packaging, the surface of the multilayer PCB assembly should be cleaned and dried, and sprayed with conformal paint.

4. Anti-vibration packaging

Put the packaged multilayer PCB assembly board into an anti-static packing box. When placed vertically, stack no more than two layers upwards, and place a partition in the middle to keep it stable and prevent shaking.

Advantage of multilayer pcb

A multilayer PCB board is composed of multiple single panels. Multilayer PCB boards are suitable for complex designs, and due to the high circuit density, multilayer PCBs are more powerful and suitable for advanced equipment. Multilayer PCBs can withstand harsher conditions as the number of layers increases. Multilayer PCBs are small in size and light in weight.
