China PCB Industry Landscape and Manufacturing Trends The printed circuit board industry is no longer distributed evenly across the world. Fabrication capacity, engineering depth and the product mix available from any given region differ enormously, and those differences decide what a hardware team can actually buy, at what price, and…

PCB Ingress Protection Testing: Key Process and Quality Checks Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB ingress protection testing gives you a practical advantage…

PCB Shock Test Setup: Key Process and Quality Checks Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB shock test setup gives you a practical advantage…

PCB Gasket Sealing: Closing the Gap to Water Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB gasket sealing gives you a practical advantage when you…

PCB Salt Spray Test: A Factory-Floor Review Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB salt spray test gives you a practical advantage when you…

PCB Design Around a High-End Applications Processor A high-end applications processor is no longer a single chip surrounded by a few peripherals. It is a small system: several high-speed serial links, a display pipe, a memory controller that wants its own stack-up, and a power architecture with a dozen rails…

Precision PCB Assembly for Medical Robotics A surgical robot, a rehabilitation exoskeleton or an imaging gantry contains several electronic subsystems that must work together with predictable behaviour over years of use. The control loops run continuously, the actuators produce electromagnetic noise next to sensitive feedback channels, and the assembly may…

RF and Thermal Layout Rules for Microwave Transmitter PCB Assemblies A microwave transmitter runs hot, runs continuously and cannot tolerate a small error in the wrong place. At several gigahertz a fraction of a decibel of extra loss reduces the link margin, a few degrees of phase drift spoils a…

CEM-1 PCB: Manufacturing and Assembly Guide CEM-1 is the laminate that sits between paper-based phenolic board and woven glass FR-4, and it exists because a large part of the electronics market does not need the mechanical performance of FR-4 but does need something better than paper. It is a composite:…

PCB Pressure Test for A Housing: What Buyers and Engineers Should Check Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for…
