PCB (Printed Circuit Board) is the basis of the entire PCBA, and its design determines the product function and performance. It provides connection and support for components to ensure the normal operation of the circuit. The entire process includes schematic design, layout and wiring, board selection, and processing and manufacturing. After the design is completed, the PCB needs to go through multiple processes such as manufacturing, etching, drilling, and pad processing.
The selection of electronic components directly affects product performance and cost. We will purchase components that meet the requirements based on the BOM (Bill of Materials) provided by the customer, refer to the specific performance requirements and budget requirements of the components, and ensure the qualifications of the supplier and the quality stability of the components.
This is the core link of PCBA processing. We will choose different assembly methods according to different components. - SMT (Surface Mount Technology) patch: electronic components are mounted on the surface of PCB, suitable for small components. - DIP (Dual In-line Package) plug-in: suitable for larger or specific functional components, which need to be completed by wave soldering or manual soldering.
Complete the fixed connection and electrical connection of components to ensure that each component is firmly and reliably connected to the PCB. The main links include reflow soldering, wave soldering and manual soldering, and the appropriate soldering method needs to be selected according to the type of component.
Testing is a key link to ensure product qualification. Verify whether the circuit performance and function are normal and troubleshoot potential problems. The process mainly includes AOI (automatic optical inspection), ICT (in-circuit testing), FCT (functional testing), etc. to ensure that product performance meets design requirements.
Complete the final packaging of the product and deliver it to the customer. Regarding product packaging, we will use anti-static packaging and affix labels and logos to ensure that the product is safely delivered to the customer. It not only protects the product, but also enhances the brand image of Jeking.
