Consequences of insufficient component-to-board edge spacing; Devices that are too close to the edge may interfere with the operation of automated assembly equipment, such as wave or reflow soldering machines. Devices that are too close to the edge may be damaged during the panelling of the board at the end of the manufacturing process. This

PCB Design Preparation 1. Information to be provided with hardware C ●Accurate schematic diagrams, including paper and electronic files and error-free network tables. ● An official BOM with component codes. the hardware engineer should provide a DATASHEET or physical object for components that are not in the package library and specify the order in which
For beginners, there are many “layers” in PCB circuit boards, and many beginners are easily confused by the various PCB layers when learning PCB design. Below, let the engineer summarize the definition of various layers in PCB design for you to help beginners better understand and master. There are many different definitions of the specialized

Why do PCBs need to be stencilled? PCBs are assembled to meet production requirements. Some PCB boards are too small to meet the fixture requirements, so they need to be assembled together for production. In order to improve the soldering efficiency of SMT. Only need to pass through the SMT once to complete the soldering
What is hole-in-pad? Hole in the disk refers to the hole in the pad, the pad for the SMD disk, usually refers to 0603 and above SMD and BGA pads, usually referred to as VIP (via in pad). Plug-in holes in the pad can not be called a hole in the disk, because plug-in holes
Never Underestimate PCB Half-Hole Boards What is a PCB half-hole? Half vias are rows of holes drilled along the boundaries of a PCB for production purposes. When the holes are plated with copper, the edges are trimmed off so that the holes along the border are halved. The edges of the PCB look like a plated
Preface: In the complex PCB design and manufacturing process DFM manufacturing analysis is particularly important. DFM Design for Manufacturing, Design for manufacturability (DFM) DFM role is to improve the manufacturing process of the product. Today’s DFM is the core technology of parallel engineering, because design and manufacturing are the two most important links in the product life

What is the BOM? A simple understanding is: the list of electronic components, a product consists of many parts, including: circuit boards, capacitors, resistors, diodes, crystals, inductors, driver chips, microcontrollers, power supply chips, step-up and step-down chips, LDO chips, memory chips, connectors, connectors, pins, rows of mother, and so on. Engineers will be based on

What is Rigid-Flex PCB? Rigid-Flex printed circuit boards (PCBs) are advanced circuit boards that combine the features of both rigid and flexible technologies. They consist of multiple layers of flexible substrates permanently attached to one or more rigid boards. This design allows for both rigid and flexible areas within a single package, making Rigid-Flex PCBs
Flexible circuits, commonly known as flex circuits or flexible printed circuit boards (FPC), are crucial components in the world of electronics. Comprising a thin insulating polymer film with conductive patterns, these circuits are often coated for protection. Since their inception in the 1950s, flex circuits have evolved into a vital interconnection technology for advanced electronic
