1. PCB (Printed Circuit Board), also known in Chinese as 印刷电路板, is a crucial electronic component. It serves as both the support structure and the electrical connection carrier for electronic components. PCB is often referred to as the “mother” of electronic products because it is printed with electronics, hence the name “printed circuit board.
2. Prior to the advent of PCBs, the interconnection between electronic components was achieved through direct wiring. Today, wires are mainly used for experimental purposes in laboratories, while printed circuit boards dominate the electronics industry.
3. The PCB production process includes contacting the manufacturer for drilling holes, creating copper patterns, transferring patterns, electroplating, thin film etching, applying green oil characters, gold-plating fingers, and forming.
4. Unique advantages of PCBs include high density, high reliability, design flexibility, productivity, testability, composability, and maintainability.
5. How did PCBA develop?
6. PCBA, short for Printed Circuit Board Assembly, refers to the entire process of assembling the empty PCB board through SMT or DIP plug-in methods. OEM processing encompasses PCBA manufacturing, OEM production, EMMS electronic product development and design, and ODM.
1. It is committed to meeting the diverse manufacturing needs of OEMs/customers and provides comprehensive procurement services for product components. This includes all-round services for production, assembly, and technical support.
2. SMT Chip Processing and DIP Plug-in Processing Introduction
3. SMT and DIP are methods used to integrate components onto the PCB. The main difference is that SMT does not require drilling holes on the PCB, while in DIP, the component pins need to be inserted into pre-drilled holes. Shenzhen PCBA OEM primarily processes medical and industrial control motherboards and power supplies, automotive electronic controls, communication devices, household appliances, computer peripherals, instruments, and other related products.
4. SMT (Surface-Mounted Technology) is used to mount microelectronic components onto the PCB. The production process involves PCB board positioning, solder paste printing, component placement by a mounting machine, soldering in a furnace, and final inspection. SMT integration is highly sensitive to component positioning and size, and the quality of solder paste and printing also plays a crucial role.
5. DIP (Dual In-line Package) involves inserting components into the PCB, typically used when components are too large for SMT or when the production process does not accommodate SMT. The industry employs manual or robotic methods for DIP. The main production processes include applying back glue (to prevent incorrect tinning), component insertion, inspection, wave soldering, brushing (to remove residues from the soldering process), and final inspection.
6. Difference Between PCB and PCBA
7. After this brief introduction, you should understand that PCBA typically refers to a processed circuit board and can be considered a completed product. In other words, PCBA represents a PCB that has undergone all necessary processing steps. On the other hand, PCB refers to an unpopulated printed circuit board without any components. Simply put, PCBA is a finished board, whereas PCB is a bare board.
