What Standards Define Quality & Compliance in Medical PCB Assembly?
Medical PCB lives depend on IPC Class 3, ISO 13485 & FDA compliance. Prevent failures: learn material requirements, cleanroom protocols & vital supplier certifications for lifesaving devices.
How thick is 1 oz copper on a PCB?
PCB copper thickness guide: 1 oz standard balances cost/performance. Use 2 oz for high-current/high-heat design zones. Avoid thick copper for high-frequency/sensitive price projects.
Blind, Buried, or Through Via?
Master PCB via selection: balance cost, density & signal needs. Proper sizing prevents overheating. Understand via-pad differences. Prevent failures with plating standards.
Is Your FR-4 Board Right for High-Speed Signals?
FR-4 supports MHz designs affordably but suffers dielectric losses >5GHz/long traces. Optimize layer stackup, thermal design & shielding – or switch to low-loss laminates for GHz needs.
How to choose the right surface mount IC package?
Choose IC packages by balancing signal speed, heat dissipation, board space, and cost. Avoid overheating and failures—learn key uses for BGA, QFN, QFP & SOT packages.
Why Do Cold Solder Joints Occur?
Cold solder joints cause device failure. Learn to spot dull/cracked joints, fix with proper reflow and tools like flux, and test using thermal/multimeter methods.
Why choose rigid flex PCB?
Rigid flex PCBs merge solid & bendable circuits to eliminate connectors, cut failure risks, boost signal integrity, and enable compact designs for medical/aerospace systems.
What are 5 critical FR4 properties?
FR4 PCB material dominates with 5 key traits: insulation, strength, flame retardancy (UL-certified), moisture resistance, and cost-efficiency. Avoid catastrophic failures by mastering specs.
What is the standard size of a PCB panel?
Optimize standard PCB panel sizes (18×24″, 12×18″) to cut costs. Choose breakaway methods wisely, minimize material waste, and avoid design errors to maximize yield and profit.
What is the potting process in PCB?
PCB potting seals assemblies in resin for extreme environment protection. Learn potting vs. conformal coating selection, process tips to prevent voids/cracks, and avoid hidden costs. Essential for harsh applications.
