Regarding SMT patch processing, many people confuse PCBA with PCB. So, what is PCB? In fact, SMT is a method of integrating components onto a PCB board. What exactly is a PCB board? Simply put, PCB circuit boards, also known as printed circuit boards, are quite familiar to many. How has PCBA evolved? What differentiates PCB from PCBA? How can electronic product planners find the right PCBA suppliers for development and production?
PCB (Printed Circuit Board), known in Chinese as 印刷电路板, is a crucial electronic component. It serves as both a support for electronic components and a medium for their electrical connections. PCB is often referred to as the “mother” of electronic products. The term “printed” circuit board comes from the method of its creation.
Before PCBs, electronic components were interconnected directly with wires. Today, wires are mostly used for testing in labs, with PCBs dominating the electronics industry.
PCB production process: Contact the manufacturer – Opening – Drilling – Copper sinking – Graphic handling – Graphic plating – Film removal – Etching – Green oil application – Character printing – Gold-plated finger formation – Testing – Final inspection.
Unique strengths of PCBs: High density, high reliability, planability, productivity, testability, assemblability, and maintainability.
2. How did PCBA evolve?
PCBA, short for Printed Circuit Board Assembly, refers to the process of mounting components onto a PCB, either through SMT (Surface Mount Technology) or DIP (Dual In-line Package) methods.
SMT and DIP are techniques for integrating components onto a PCB. The primary distinction is that SMT does not require drilling holes, while DIP involves inserting component pins into pre-drilled holes.
PCBA processing
SMT involves mounting small electronic components on a PCB using a mounter. The production steps are: positioning the PCB, applying solder paste, component placement by the mounter, reflow soldering, and final inspection. SMT’s success relies heavily on accurate positioning, component size, solder paste quality, and printing precision.
DIP, or “Dual In-line Package” insertion, is used for larger components that cannot be placed using SMT. It involves manual or robotic insertion of components, followed by adhesive application, inspection, wave soldering, cleaning, and final inspection.
Do you understand the difference between PCB and PCBA? From the above explanation, it’s clear that PCBA refers to a fully assembled product circuit board, while PCB denotes an unpopulated board. In essence, PCBA is a completed product, whereas PCB is a bare board. Many confuse PCB with PCBA, but understanding these distinctions clarifies that PCBA is a finished assembly process.
