Product Description (ready to use):

The Cyrix 486 Ceramic CPU is a vintage microprocessor from the early 1990s, manufactured using a high-quality ceramic package rather than modern plastic encapsulation. These ceramic CPUs are highly sought after in the precious metal recycling industry because they contain significantly more gold than later plastic CPUs.

The ceramic package features a gold-plated lid (often visible through a window or fully plated), gold-plated pins or leads, and gold bonding wires inside. Additionally, thick-film gold traces on the ceramic substrate add to the total gold yield. For recyclers and refiners, the Cyrix 486 represents an excellent source of recoverable gold from e-waste.

Gold-Bearing Components in Cyrix 486 Ceramic CPU:

Note: Actual gold yields vary. Typical range: 0.3 – 1.0 grams per kilogram of ceramic CPUs.

Key Specifications:

• Manufacturer: Cyrix Corporation (originally)

• Model Series: 486 series (486SLC, 486DLC, 486DRX, etc.)

• Package Type: Ceramic Pin Grid Array (PGA) or Ceramic Quad Flat Pack (CQFP)

• Pin Count: Typically 168–208 pins

• Lid Material: Gold-plated copper or Kovar (often gold visible)

• Markings: Cyrix logo, 486 model number, speed rating (e.g., 25MHz, 33MHz, 40MHz)

• Era: Early to mid-1990s

Key Applications:

• Precious metal recycling and gold recovery

• E-waste refining and material processing

• Vintage computer collectors (rare or boxed examples)

• Gold scrap investment and trading

• Laboratory testing for precious metal content

Available Quantities:

• Loose individual units (for testing or collecting)

• Small lots (10–100 pieces)

• Wholesale lots (100–1,000+ pieces)

• Bulk boxes (by weight – kg or lb)

• Full pallets (mixed ceramic CPU lots)

Why Cyrix 486 vs Other Ceramic CPUs?

Processing Tips for Recyclers:

• Remove gold-plated lid using heat or mechanical methods

• Depopulate pins using decapsulation equipment or chemical stripping

• Process ceramic bodies with aqua regia or cyanide-based leaching (professional refining only)

• Always follow environmental and safety regulations for e-waste processing

Quality & Condition:

• We supply untested, as-is scrap CPUs (no guarantee of functionality)

• Pins may be bent or slightly oxidized – still fully recyclable

• Ceramic bodies may have minor chips or cracks – no effect on gold recovery

• Gold content not assayed per unit; pricing based on weight and typical yields

• Some units may still have original heat sinks or adhesive – included in weight
