BGA PCB Surface Finish Risks and How to Prevent Soldering Defects As electronic products continue to become smaller, thinner, and more powerful, BGA assembly has become increasingly common in high-density electronic devices. Ball Grid Array (BGA) packages place solder balls underneath the component body, allowing a large number of…

  How to Do PCB Panelization for SMT Assembly In modern electronics manufacturing, PCB Panelization is widely used to improve production efficiency, simplify handling, and reduce manufacturing costs. Instead of processing individual circuit boards one at a time, multiple PCB units are arranged into a larger manufacturing panel and processed…

  PCB Panelization for SMT Assembly: Complete Design Guide In modern electronics manufacturing, PCB panelization is widely used to improve production efficiency, reduce handling time, and optimize manufacturing costs. Instead of processing every individual printed circuit board separately, multiple PCB units can be combined into a larger manufacturing panel and…

  How to Prevent FPC Pad Lift-Off: 8 Design Methods for Better Pad Adhesion FPC pads provide the electrical and mechanical interface between a flexible circuit and electronic components or external wires. However, because an FPC uses a thin and flexible substrate, its copper pads can be more vulnerable to…

  PCB Via vs. Pad: Differences, Hole Tolerances, and Design Guidelines When designing a printed circuit board, understanding the difference between a PCB Via and a PCB Pad is essential for achieving reliable electrical performance and smooth manufacturing. Although both can contain holes and connect to copper features, they serve…

  How to Design Through-Hole Pads with Copper Exposure on One Side and Solder Mask Coverage on the Other In conventional PCB design, through-hole components are generally designed with solderable copper pads exposed on both sides of the circuit board. However, some applications require a through-hole pad to be soldered…

  FPC Tear Prevention Line: Purpose, Design Requirements, and Best Practices Flexible printed circuits are widely used in compact and lightweight electronic products because they can bend, fold, and fit into irregular mechanical spaces. However, their thin and flexible structure also creates unique challenges during manufacturing and depanelization. Unlike rigid…

FPC-to-PCB Connections: 7 Common Methods Explained How Does FPC Connect to PCB? As electronic products become smaller, thinner, and more integrated, FPC to PCB connection technology has become increasingly important. A Flexible Printed Circuit (FPC) provides lightweight construction, flexibility, and three-dimensional routing, while a rigid PCB provides mechanical support, component…

SMT Flying Probe Testing: Process, Capabilities, Limitations, and Benefits What Is SMT Flying Probe Testing? SMT Flying Probe Testing is an electrical testing method used during surface mount technology (SMT) production to verify PCB assembly quality, component connections, and circuit integrity. Unlike traditional ICT systems that use a fixed bed-of-nails…

  How to Panelize PCBs for SMT Assembly In electronics manufacturing, PCB Panelization is the process of combining multiple individual printed circuit boards into a larger production panel. Panelization allows manufacturers to process several boards at the same time during solder paste printing, component placement, reflow soldering, inspection, and other…
