1. Preventing Tin-Connected Short CircuitsThe safety spacing is closely related to the steel mesh expansion during SMT patch processing. Factors such as steel mesh opening size, thickness, tension, and deformation can cause welding deviations, leading to short circuits due to tin bridging. 2. Facilitating OperationsAdequate spacing ensures operational efficiency during hand welding, selective welding, tooling, […]
Design for Manufacturability (DFM) integrates CAE (Computer Aided Engineering), CAD(Computer Aided Design), CAPP(Computer Aided Process Planning), and CAM (Computer Aided Manufacturing) with manufacturability analysis, ensuring manufacturing factors are considered at the design stage. From the aspect of focus: Design for manufacturability, this includes: During production process a structured analysis is done, and flow charts are

Chip component packaging is a critical aspect of semiconductor device manufacturing. With the rapid development of technology, especially in SMT (Surface-Mount Technology), there are numerous packaging forms used in the electronics industry. Some packaging types, such as chip capacitors and resistors, have standardized sizes, while others, especially IC parts, are continuously evolving. Traditional pin packaging
There are many aspects to the cost of PCBA manufacturing. The core components mainly include the materials for the PCB bare board, the cost of SMT processing, and the cost of components. In addition to these core components, several other processes directly impact the cost of PCBA. Some of these factors are often overlooked, including

The engineering files used in PCB production include PCB files, ODB++ files, Gerber files, and EXCELLON files. Among these, Gerber files are used for photoplotting to produce film for exposure and screen printing. EXCELLON format files serve as drilling and milling program files, facilitating hole drilling and shaping. PCB files must be converted into Gerber
SMT assembly chip processing is with the development of electronic products to the development of high precision, fine pitch direction, and SMT chip processing components of the minimum pitch design needs to be able to ensure that the PCBA pads are not easy to short and also take into account the maintainability of the components.

The analogy that “ICs are just smaller versions of multilayer PCBs” is not entirely without merit. As processes become more differentiated between PCB manufacturers and assemblers, PCB design may begin to embrace some of the same philosophies used by the IC design industry to deal with escalating complexity. DFM manufacturability analysis is especially important in

Vias are
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
