PCB Knowledge

New electronics require smaller size, greater speed, and enhanced reliability. This has made sophisticated PCB designs prevalent. Rigid Flex PCB and HDI PCB are two popular choices. The two assist engineers in creating small and high-performance products. Howe

Even the best of designers can agree that there’s nothing more disappointing than spending months designing the printed circuit board just to discover that it either warps during assembly, overheats in the field or quietly bleeds out signal at high frequ

Introduction In LHD TECH’s delivery record, over 82% of after-sales quality disputes stem not from the materials themselves, but from a mismatch between the selected base material and actual operating conditions. Therefore, we never recommend FR-4 or CEM

Introduction Every circuit in electronics is design to accomplish the same task: process, store, and transfer signal. But, how signal are manage and interpret defines the two great foundation of electronics — analog circuits and digital circuits. Understand th

Introduction to Amplifier Circuit Diagrams Studying, building, or troubleshooting electronic circuits is impossible to understanding the amplifier circuit diagram. From boosting tiny signals in microphones to driving room-shaking speakers in a power amplifier,

Introduction to PCB OSP Surface Finish In PCB manufacturing, protecting the exposed copper surface is crucial as it directly affects assembly yield, product reliability, and cost control. Organic solderability protectant (OSP), as a transparent, economical, an
