FPC Flexible PCB Design Guide: 8 Key Points You Must Know

图片
  FPC flexible board , namely Flexible Printed Circuit Board, is a type of printed circuit board made from flexible substrates, often referred to as soft circuit boards or flexible circuit boards. FPC flexible boards have now been widely used in modern electronic products, and it is believed that everyone has come into contact with them to some extent. FPC is thin, lightweight, and bendable, and can be processed into any shape and size, complementing FR-4 PCB rigid boards. However, since it is different from rigid PCB boards, there are some special considerations in design. Today, we will discuss these. Today, we will mainly introduce the key design points of FPC, which are divided into 8 aspects: Outline and drilling design Circuit design Edge gold finger design Solder mask design Silk screen design Panelization design Stiffener design Board thickness specifications FPC Design Pitfall Avoidance Guide Drilling, board frame, circuit, solder mask, and text design for flexible boards ...

Basic Knowledge of SMT, a Very Practical Surface Mount Technology of Electronic Components

The full name of SMT is Surface mount (or mounting) technology. SMT is the abbreviation of Surface Mount Technology, also known as surface mounting or surface installation technology. It is currently the most popular technology and process in the electronic assembly industry. Generally speaking, the specified temperature in the SMT workshop is 25±3℃. SMT Mounting Machine Solder Paste: When printing solder paste, the materials and tools required for preparation are solder paste, stencil, scraper, wiping paper, clean paper, cleaning agent, and stirring knife. The components of solder paste include: metal powder, solvent, flux, anti-sag agent, and activator. Its main components are tin powder and flux, with a volume ratio of approximately and a weight ratio of approximately 9:1. The flux starts to volatilize in the constant temperature zone and performs chemical cleaning operations; the main functions of the flux in soldering are to remove oxides, break the surface tension of molten tin, ...

Flexible PCB

  What is FPC? FPC, or Flexible Printed Circuit , originated in the 1970s in the United States as a technology developed for aerospace rocket technology. It is a printed circuit made from polyester film (PET) or polyimide (PI) as the substrate, characterized by high reliability and excellent flexibility. FPC can be freely bent and folded in three-dimensional space. The structure of flexible circuits includes insulating films, conductors, and adhesives, acting like a universal glue in the electronic world, bonding various components together to enable communication and collaboration. Advantages of FPC High-Density Wiring Capability : The ability to bend and connect circuits to necessary positions allows soft boards (flexible PCB) to be used in small-sized, high-density applications. High Reliability : R-FPC utilizes advanced manufacturing processes and materials to ensure circuit stability while enhancing the reliability of the flexible circuit board. Good Mechanical Performance : T...
