What is a PCB laminate?
Master PCB laminate properties, defects, and material differences (prepreg vs core). Prevent high-speed signal issues, delamination, and costly failures. Essential for reliable circuit boards.
What Are Standard PCB Panel Sizes?
Optimize PCB costs and assembly: use standard panel sizes (e.g., 18″x24″), choose V-Score/Breakaway Tabs wisely, control costs via material utilization, and boost SMT efficiency with fiducials/thermal balance.
What is PCB backdrilling?
Learn how PCB backdrilling eliminates signal stubs for high-speed designs. Optimize layer stackups, apply the 3W rule to avoid crosstalk, and control costs by managing hole density, aspect ratio, materials, and tolerances.
How do you fix “invisible” PCB faults?
Diagnose hidden PCB failures caused by moisture/thermal stress. Learn cost breakdowns ($50-$800) and step-by-step trace repair techniques using expert-level inspection methods.
What Are Low-Cost PCB Test Points?
Save money on PCB testing! Use low-cost test points like modified vias, flying probes for prototypes, and smart alternatives to carbon ink. Optimize density for max coverage & affordability.
What are the Most Common Circuit Board Components？
Master circuit board components: identify resistors, capacitors, transistors. Learn active vs passive, SMD vs through-hole differences, and crucial specs to build or repair electronics.
How do you choose between shield cans and conformal coatings?
Optimize PCB shielding: Use cans for repairable EMI/impact protection and coatings for lightweight environmental sealing. Master grounding, flexible materials, and gasket cost-benefit.
What is HDI PCB and its Function?
HDI PCBs use microvias for compact, high-performance electronics in smartphones, medical devices, and cars. Ultra HDI enables nano-scale circuits for aerospace/neural tech via submicro-vias and materials.
Why do microwave PCBs fail?
Microwave stopped working? PCB failures explained: overheating, design flaws, aging. Learn repairable vs hopeless cases & smart stackup choices to prevent future breakdowns.
SMD vs SMT: What’s the Real Difference?
Learn the critical difference between SMD components & SMT assembly. Master SMD marking decoding, industry applications, and optimal package selection to prevent design errors.
