PCBA processing is a broad term that encompasses various components, including (PCB circuit board manufacturing, PCB prototype assembly, SMT assembly processing, and electronic component procurement).

1. Selection of Electronic Components.

When selecting electronic components, it is essential to thoroughly consider the total area of the SMB and to prioritize the use of conventional electronic components whenever possible. Avoid the temptation to exclusively seek out smaller-sized components, as this can lead to increased costs. For IC devices, special attention should be given to the pin configuration and spacing. The use of QFPs with a lead pitch of less than 0.5mm should be approached with caution. It may be advisable to directly opt for PCB factory parts with BGA packaging. Furthermore, factors such as the packaging style of the electronic components, the dimensions of the terminal electrodes, the solderability of the PCB, and the reliability of the SMT devices must be considered, along with temperature tolerance (for instance, whether they can accommodate lead-free soldering requirements).


1. After selecting electronic components, it is essential to establish a database that includes installation dimensions, pin specifications, and relevant information from the SMT manufacturer.

2. Next, the choice of substrates must be considered.

3. The base material should be selected based on the usage conditions of the SMB and the mechanical and electrical characteristics of the equipment. The number of copper-clad surfaces of the base material (single-sided, double-sided, or multi-layer SPCBAMB) is determined by the SMB structure. The size of the SMB helps to assess the total unit area carrying the weight of electronic components and to determine the substrate board thickness. The costs of various material types can differ significantly. When selecting SMB substrates, one must consider the requirements of electrical equipment characteristics, including Tg (glass transition temperature), CTE, and flatness, as well as factors such as hole metallization capability and pricing.

4. Counterfeit products are prevalent across nearly every industry, making it unsurprising that counterfeit components pose a significant issue in the electronics sector. Despite ongoing efforts by the government, companies, and other stakeholders to prevent counterfeit and substandard PCB products from entering the market, they occasionally succeed in doing so. These fake components can lead to product performance issues and safety hazards.

5. Products that incorporate counterfeit electronic components can be hazardous. If these counterfeit parts fail, they can pose risks to users and may also result in malfunctioning products. In such scenarios, the counterfeit components might indirectly cause damage. For instance, counterfeit items could lead to short circuits, potentially causing fires, which can have catastrophic consequences.

6. Electronic components are critical across various fields, including aerospace, medical, military, and communication PCBA circuit boards. In these industries, equipment failure can have dire consequences. If devices malfunction due to the use of counterfeit integrated circuits and other electronic components, they may yield inaccurate test results, leading to misdiagnoses that could directly jeopardize patient safety. In aerospace, counterfeit electronic components can lead to failures that endanger the lives of pilots and crew members, and no one wants to risk using a mobile phone that could explode in their hands.
