Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits

Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

Mixed consumer electronics circuit boards; end-of-life consumer appliances and entertainment equipment; moderate precious metal content (0.01-0.10g gold average; 10-100g copper highly variable); highly heterogeneous collection (TV boards, appliance controllers, audio boards mixed together); ABSOLUTE HIGHEST supplier count commodity; volume-driven bulk commodity; medium precious metal recovery per unit; hazmat compliance variable; environmental/economic straightforward mass recycling

Acceptable Inclusions

Gold plating 0.01-0.10g average (mid-grade specification; statistical average acceptable)
Copper 10-100g highly variable (TV 50-100g, appliances 10-20g; wide range acceptable)
Solder variable (lead-free or leaded; mixed acceptable)
Nickel <5g (plating; typical)
Silver <5g (trace; typical)
Epoxy-fiberglass substrate (inert; variable weight)
Moderate dust/thermal compound (typical consumer use)
Mixed board types (heterogeneous acceptable)

Prohibited Materials

Intact batteries (separate; active hazmat)
Mercury components (explicit rejection; hazmat extreme)
Fluid leakage (oil/liquid hazmat)
Extreme corrosion (non-recoverable)

Quality Assurance

Testing protocols, sampling methods, and acceptance criteria.

Sampling Protocol

Required Test Methods

Spot Consumer Board Type Verification

Method 1

Purpose

spot-verify consumer electronics board types (TV/appliance/audio)
confirm mid-grade commodity status visually

Acceptance Criteria

Consumer board types apparent
no industrial/vintage/specialty boards obvious
mid-grade commodity status VISUAL confirmation

Procedure

Sample spot inspection (2-5%)
quick consumer board identification
specialty/industrial exclusion check only

Hazmat Spot-Check

Method 2

Purpose

spot-verify no obvious mercury/extreme hazmat
RoHS compliance ASSUMED modern standard

Acceptance Criteria

No obvious mercury/active hazmat detected
RoHS compliance ASSUMED standard modern

Procedure

Visual spot-check (2-5%)
quick mercury/active hazmat visual scan
RoHS compliance ASSUMED AUTOMATICALLY modern
