Hello, welcome back! Today I'll introduce you to a method for extracting gold from IC BGA chips. First, we'll separate the IC chip from the motherboard. Next, we'll separate the black chip from the green PCB attached to the IC chip.

You'll see there are two parts:

there's the green PCB of the IC chip and the black package that encases it.

Place the black IC chip in a beaker. In this step, we'll separate the gold wire from the compound or black material. We use 98% sulfuric acid and boil it with the IC chip at 90 degrees Celsius. In my experiments, if the temperature exceeds 90 degrees Celsius, the gold will sometimes dissolve or disappear. We should use enough sulfuric acid to cover the IC chip 2-3 times its size. After the IC package or compound has completely dissolved, rinse it with water and gently rinse it off.

This step is quite dangerous, so be careful. The sulfuric acid reacts quite violently with water.

After washing, we'll see beautiful die chips and gold wires.

If you're willing to try, You can separate the gold wire and melt it down to obtain pure gold, or you can refine it to a higher purity with aqua regia, depending on your needs. You can find a video clip of this process on our channel.

For those interested in doing this at home, please consider the safety of yourself and others. Sulfuric acid is dangerous and you should have knowledge of chemicals and precautions before working. You should wear protective clothing and stay away from people and pets.

Thank you and see you in the next video.

🔍 What is an IC Chip Die?

An IC chip die (integrated circuit die) is the small, thin slice of semiconductor material, usually silicon, that holds the actual electronic circuit. This circuit includes components like transistors, resistors, and capacitors, all packed into a tiny space.

• The die is created using photolithography and doping processes.

• It is typically just a few millimeters in size.

• Once manufactured, the die is packaged into an outer casing (ceramic, plastic, or epoxy) to form what we know as an IC (integrated circuit).

---

🟡 Gold Inside the IC Chip

Gold is used inside ICs for several important reasons:

1. Gold Wire Bonds

• Function: Gold wires connect the tiny contact pads on the silicon die to the external leads of the package.

• Why Gold?

  • Excellent electrical conductivity.

  • High corrosion resistance.

  • Reliable thermal and mechanical stability.

• Wire diameters are typically 15 to 50 microns.

• Found in older or high-end ceramic chips, military-grade ICs, or early computer ICs.

2. Gold-Plated Lead Frames or Pads

• Sometimes, gold-plated contacts are used on the lead frame or bond pads to improve reliability and conductivity.

• These are usually very thin layers, measured in microns or nanometers.

How to separate 5,000 pieces of gold plating with nitric acid in 24 hours

Hello friends, today I have some kind of printed pin, I don't know what it is. It's a gold-plated pin. The color is very beautiful. As usual, I will use nitric acid and water by mixing 1 part nitric acid and 3 parts water to dissolve the unwanted metal, leaving only the gold plating that we want. You see that this reaction looks very beautiful and the gold color looks very good. This set of work has a quantity of 5,000 pieces written on the bag label. First, I will separate the unwanted materials first. And next time, I will collect the gold that I get to extract it again. 

Gold is rare, but determination is rarer. You might not see it on your first try, but every failure is part of the map that leads you closer to success. Stay curious. Stay careful. Keep learning. Because with the right knowledge and a persistent spirit, even the most ordinary-looking scrap can surprise you with extraordinary rewards.

Gold extraction from e-waste often involves strong acids like aqua regia (nitric + hydrochloric acid), which release dangerous fumes and can cause burns or lung damage. To protect yourself:

Work in a Well-Ventilated Area or ideally under a fume hood to avoid inhaling toxic gases like nitrogen dioxide  or chlorine.

Wear Proper Personal Protective Equipment (PPE):

Acid-resistant gloves

Safety goggles or face shield

Long-sleeve lab coat or chemical-resistant apron

Respirator mask with acid vapor cartridges (if ventilation is limited)

Have Neutralizing Agents Ready:

Keep baking soda (sodium bicarbonate) or lime nearby to neutralize spills.

Have plenty of clean water on hand for rinsing skin in case of contact.

Label and Store Chemicals Safely:

Use chemical-proof containers with clear labels.

Store acids away from each other to prevent reactions.

Never mix chemicals blindly.

Always follow proper procedures—small mistakes can cause violent reactions.

Safety comes first—because no amount of gold is worth risking your health.

"Have you ever wondered what connects the tiny sensor inside a CCD camera to the rest of the electronics? The answer is bonding wires—made of either gold or non-gold materials."

Gold Wire 

"Gold wire has been traditionally used in CCD cameras for its excellent electrical conductivity, corrosion resistance, and reliability. It’s also very soft and easy to work with in delicate microelectronics. In high-end CCD sensors—like those used in scientific instruments or space telescopes—gold wire ensures stable performance over time, even in extreme conditions."

Non-Gold Wire 

"But gold is expensive. That’s why many manufacturers now use non-gold wires—like copper or silver-coated aluminum. These offer similar conductivity and are much cheaper, but they can oxidize faster and are harder to bond. Still, with advances in packaging technology, non-gold wires are becoming more common in consumer-grade CCD cameras, like those in home security or older digital cameras."

Conclusion 

"In short, gold wire means better reliability and longevity—perfect for critical applications. Non-gold wire saves cost and is ideal for mass production. Both play vital roles in the world of CCD cameras."

Gold plays a critical role in the design and function of CCD (Charge-Coupled Device) sensors found in professional video cameras. These cameras demand exceptionally high image quality, speed, and reliability, and gold helps achieve that — even though it’s used in tiny amounts. Here’s a detailed explanation of how and why gold is used inside a CCD camera sensor:

---

📸 What Is a CCD Sensor?

A CCD sensor is the core component that converts light into electrical signals to create a digital image. In professional 3CCD cameras, there are three separate CCD chips — one each for red, green, and blue light. These sensors are highly sensitive and must transmit tiny, precise electrical signals with minimal interference.

To do this reliably in high-performance environments, gold is used in several critical areas.

---

🔩 Where Is Gold Used in CCD Sensors?

1. Gold Bonding Wires

• Function: Connects the silicon CCD die (the actual chip) to the legs or pads of its ceramic or plastic package.

• Why gold?

  • Gold is ductile (easy to draw into fine wires), making it ideal for bonding.

  • It’s highly conductive and ensures fast, accurate signal transmission.

  • It resists corrosion, which is critical for long-lasting, stable performance.

Each CCD chip may contain dozens of ultrafine gold wires, often just 1–2 microns thick.

2. Gold-Plated Leads and Pads

• The external pins or pads that connect the CCD to the main circuit board may be gold-plated.

• Gold prevents oxidation, ensuring clean electrical contact over the lifetime of the camera.

3. Internal Substrate and Layer Connections

• Inside high-end ceramic CCD packages, gold may also be used in thin internal layers or traces to distribute signals from the sensor to the processor.

• This ensures consistent performance under thermal and mechanical stress during long shooting sessions.

---

🧠 Why Not Use Copper or Silver?

• While copper and silver are also excellent conductors, they:

  • Oxidize easily, which can cause signal degradation over time.

  • Lack the reliability in ultra-fine wires used in bonding.

  • Are harder to bond at the microscopic level during chip packaging.

Gold, in contrast, maintains perfect contact even in harsh environments — heat, moisture, and vibration — which are common in professional filming settings.

---

🎥 Importance in Professional Video Cameras

Professional cameras like Sony's 3CCD DVCAMs or broadcast cameras rely on precision and durability. Gold use in CCDs contributes to:

• Accurate color capture

• Low noise and high signal integrity

• Reliable performance over years of use

• Consistent image quality, even in extreme shooting conditions

For example, in live broadcasting, a single dropped frame or flicker is unacceptable. The gold-enhanced connections help ensure seamless image flow from the sensor to the processing system.

---

🧪 Summary: Why Gold in CCD Sensors?

Gold Usage Area	Purpose	Benefit
Bonding wires	Connect chip to package	Ultra-reliable, corrosion-free links
Connector pins/pads	External electrical interface	Stable and clean signal transfer
Internal circuit traces	Signal routing inside the CCD package	High-performance and durable

---

💡 Final Thought

Although the actual amount of gold in a CCD sensor is very small — just fractions of a gram — its role is essential. Without it, the image stability, accuracy, and longevity required by professional users would not be possible.

That’s why even obsolete cameras still attract interest from recyclers: CCD sensors and other gold-bearing components represent not just engineering marvels, but also tiny reservoirs of precious metal.
