The PCBA processing costs consist of the following parts: PCB Board Cost (If you provide it yourself, there is no charge) Component Procurement Cost (If you provide this as well, there is also no charge) SMT Processing Cost (SMD Mounting + DIP Soldering) PCBA Testing and Assembly Cost 1. PCB Board Cost If you want … Read more
SMT Top Networking Circle A professional circle for sharing networking resources and achieving career advancement. In simple terms, the PCBA process is a combination of the SMT processing and DIP processing. Depending on the requirements of different production technologies, it can be divided into single-sided SMT assembly processes, single-sided DIP insertion processes, single-sided mixed assembly … Read more
1. What Are the Inspection Standards for PCBA Boards? First, let us understand the introduction of quality inspection standards. 1. Serious defects (denoted as CR): Any defect that can cause harm to a person or machine or endanger life safety, such as non-compliance with safety regulations, burning machines, electric shock, etc. 2. Major defects (denoted … Read more
Simply put, what is PCB? PCB = printed circuit board; the Chinese name is 印制电路板, also known as printed circuit board, is an important electronic component, serving as the support for electronic components and the carrier for electrical connections between electronic components. Because it is made using electronic printing techniques, it is called a ‘printed’ … Read more
When learning about PCB design, we often encounter two very similar concepts: PCB and PCBA. We know that PCB stands for Printed Circuit Board, but what about PCBA? What is the relationship and difference between them? About PCB PCB stands for Printed Circuit Board, which is a circuit board made using electronic printing technology. It … Read more
In the field of electronic manufacturing, the storage phase of PCBA is crucial for ensuring product quality. From SMT chip processing to finished product assembly, the storage of PCBA at different stages has different technical requirements. How to store these PCBAs is something every engineer must consider. 1. Storage After SMT Chip ProcessingAfter the SMT … Read more
First, we need to understand what packaging is, which refers to the casing installed on semiconductor integrated circuit chips. It serves to place, fix, seal, protect the chip, and enhance thermal performance, while also acting as a bridge between the internal world of the chip and the external circuit, allowing for different appearances based on … Read more
PCB (Printed Circuit Board) is a bare board without assembled electronic components, primarily composed of an insulating substrate and conductive copper foil, providing only electrical connections and physical support. Its manufacturing process includes design, etching, drilling, etc., without involving component soldering or testing. For example, a PCB blank for a smartphone contains only circuit patterns … Read more
1. SMT: The “Main Force” of Modern Electronic Manufacturing (1) Technical Principles SMT (Surface Mount Technology) is a technique that directly mounts electronic components onto the surface of printed circuit boards (PCBs). The core of this technology lies in the precise placement of components onto the PCB pads using automated equipment, followed by a reflow … Read more
