During PCBA processing, there will be many special processes, which will immediately bring restrictions on the PCB board. If the PCB board does not meet the requirements, it will increase the difficulty of the PCBA soldering process, which may eventually lead to soldering defects and the board is

Shenzhen Viasion has its own SMT chip factory, which can provide SMT chip processing services for the smallest package 0201 components, and supports processing with incoming samples and PCBA OEM materials. Next, I will introduce the process of SMT chip processing. Factors affecting cost.

SMT processing efficiencyGenerally, large-volume circuit board processing requires high efficiency for the entire SMT processing plant. Because whether PCBA is a high-precision or ordinary product, its process is the same, and all processes must be completed before it can be considered complete. Esp

Virtual welding, also known as false welding, is a state of disconnection. It is a kind of poor soldering, which is a very important reason for the high repair rate of PCBA in the early stage. Next, Shenzhen Viasion Electronics, a PCBA processing manufacturer in Shenzhen, will introduce the reas

In PCBA processing, the processed electronic products need to be inspected. Only the products that pass the inspection can be shipped. Next, Shenzhen PCBA processing manufacturer-Shenzhen VIASION Electronics will introduce the inspection requirements of PCBA processed products.

The PCBA manufacturing process is a very complicated process. The entire PCBA process seems to be different from PCB in only one word. In fact, it has changed a lot. PCBA has a series of PCB-based back-end processes, such as solder paste printing, SPI inspection, SMT processing, reflow soldering,

Now the domestic electronic processing industry is very prosperous, and when PCBA proofing is performed, there are often serious material consumption and slow processing processes. These two situations virtually increase the cost of research and development of sample patches. Next, Shenzhen SMT ma

In PCBA processing, two common soldering methods are reflow soldering and wave soldering. So in PCBA processing, what is the role of reflow soldering, what is the role of wave soldering, and what is the difference between them? Next, Shenzhen PCBA processing manufacturer-Shenzhen VIASION Electroni

Viscosity and surface tension are important properties of PCBA solders, and excellent PCBA solders should have low viscosity and surface tension when they are melted. Whether it is reflow soldering, wave soldering or manual soldering, surface tension is an unfavorable factor for the formation of g

Basic requirements for BGA pad design 1. The center of the pad of each solder ball on the PCB coincides with the center of the corresponding solder ball at the bottom of the BGA. 2. The PCB land pattern is a solid circle, and the via hole cannot be processed on the land. 3. After the via hole is
