High Grade Board
Key Characteristics:
Dense array of ICs and BGA chips, multiple gold-plated connectors, high number of MLCCs, thick copper layers, substantial heatsink mounting.
Typical Sources:
Server motherboards, high-end gaming computers, telecom equipment, military-grade hardware, enterprise networking gear.
Value:
Premium pricing due to high precious metal content, especially gold in connectors and palladium in capacitors.
Low Grade Board
Key Characteristics:
Sparse component placement, mostly bare PCB, plastic connectors, few MLCCs, minimal copper content.
Typical Sources:
Consumer televisions, budget printers, cheap laptops, basic monitors, entry-level electronics.
Value:
Lower pricing due to minimal precious metals. Primary value from PCB scrap and small amounts of copper.
