Gold-plated SMD (SAW filters, RF modules, shields)

Colour stability. Real gold plating is a warm even yellow that doesn't tarnish, dull or grey with age. On a twenty-year-old board, whatever still looks freshly yellow is gold. Tin looks pale grey-white; brass goes brown or green; old solder is dull.

How to spot it

Gold-lidded SAW filters and RF modules (small metal-lid rectangles on phone and RF boards), gold-terminated ceramic packages, gold-plated resistor networks and MELF on mil boards, gold-plated shield cans, gold pad and via fields.

Metal content

Gold0.5–1.5 g/lbthin plating, needs volume
Silver0.2–1 g/lb

At 4 Aug 2026 spot prices that works out to $118 per pound of contained metal — Gold 0.9 g = $117, Silver 0.5 g = $0.95. A refiner paying $25 returns about 21% of that, which is normal: refining costs money and the buyer takes a margin.

Safe removal

Working temperature: Preheat 250–280 °C / hot air 330–370 °C

Preheat plate 250–280 °C and scrape into a pan, or hot air 330–370 °C for selective picking.

Hazards

☠ Lead — dust more than fume

NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.

💨 Fumes, ventilation and open flame

NEVER burn boards, wire insulation or plastic. Ever.
