Recycled gold from CPU computer scrap

At Chips Etc. we often get inquires into what is the value of gold found in vintage computer chips and other electronic items.

Our best advice is to always check into the rarity and collect-ability of your computer chip before considering sending it to a precious metal refiner with the intent of scrapping it for its gold content. It may be worth quite a bit more due to it's collectible value than in it's scrap gold value!

There is very little profit from extracting the gold content found in most computer chips and electronic components yourself unless you have significant quantities of them to be processed. Refining Gold & other precious metals (including silver, palladium & platinum) from CPU's & electronics is typically not profitable unless it's done professionally and in large quantities on a large scale; when processing just a few items the cost is often higher than the value of the gold that is reclaimed. More importantly, the process of refining gold involves working closely with hazardous materials including nitric and hydrochloric acids, as well as Mercury, and should only be performed safely by experienced Gold refiners.

👉👉👍Gold is used in electronics mainly in the form of electroplating chemicals, gold bonding wire and sputter targets. Smaller quantities are used in hybrid inks and solders. The largest use of gold in electronics is as an electroplated coating on connectors and contacts.
Wire Bonding
Most semiconductor packages use very fine gold wires to make
electrical connections between the semiconductor chip and
the leadframe within the package These wires are typically
2mm long and 25μm thick so only about 20 nanograms of
gold is used per wire. However, some ICs can have over 200
wire bond connections and it is estimated that about 80, 000
million ICs were manufactured in 2001 which in total
accounts for a large quantity of gold. The quantity of gold used
for wire bonding is continually increasing as more and more ICs
are manufactured. Gold Fields Mineral Services estimate that
demand for gold bonding wire has doubled since 1994 to
about 100 tonnes in 2000 and the continuing long term
demand for new consumer electronics will ensure that this
growth continues
Wire bonding is carried out thermosonically, which uses a
combination of heat and ultrasonic energy, or ultrasonically
without heat. The use of heat alone is rarely used and is
relatively slow. Gold is used for several reasons. Bonding with
gold can be carried out thermosonically with very high
reliability. This is essential where possibly millions of devices
having over 100 leads are manufactured. Manufacturers do
not want to carry out complex and costly tests on every
device and so rely on being able to achieve a very high yield
of good ICs. Another advantage with gold is that ball bonds
can be made at a rate of 20 bonds per second. Aluminium is
also used for wire bonding (ultrasonically) but reliable ball
bonds cannot be made and so wedge bonds have to be used
which occupy more space than ball bonds and can be
bonded at a rate of only 8 per second. Gold does not oxidise
or corrode so packages do not need to be hermetically
sealed.

Current and Future
Uses of Gold in
Electronics
The applications for gold in electrical and electronic
components are many and varied, and the quantity
used is growing steadily especially with the growth in
consumer electrical and electronic goods. This paper
considers the various applications in the context of the
physical and chemical properties of gold relative to
other candidate materials. The question of reliability
versus cost inevitably enters into the decision to use
gold in a particular application, but the use of gold is
widespread nevertheless, since it is often cost
effective.
Gold has a wide variety of uses in electronics and electrical
equipment. Its use has steadily increased during the last 20
years to 280 tonnes in 2000 (1). It has a relatively high price
which limits where it is used and equipment manufacturers put
in a great deal of effort trying to find lower cost alternatives,
not always with success. There are an increasing number of
new applications for gold which more than replace those
applications where gold has been replaced. Frequently, gold is
used at the development stage for a new product and is
chosen for its excellent properties and reliability. If the product
is manufactured in relatively small numbers, there is little
incentive to change but where the scale of production is much
larger, lower cost alternatives may sometimes be sought.
How and Where Gold is Used
Gold is used in electronics mainly in the form of
electroplating chemicals, gold bonding wire and sputter
targets. Smaller quantities are used in hybrid inks and solders.
The largest use of gold in electronics is as an electroplated
coating on connectors and contacts. This is followed by gold
bonding wires within semiconductor packages. Other uses
include hybrid circuits, solderable coatings for printed circuit
boards and components, as gold-based solders and for metal
layers on semiconductors as conductor tracks and contact pads.
Connectors and Contacts
Gold is used on connectors and contacts because it has
excellent corrosion resistance, high electrical conductivity
(only copper and silver are better) and, alloyed with small
amounts of nickel or cobalt, has good wear resistance. For
low voltage, low current and low contact force applications,
gold is the best material.

Before burning the scrape which powder you add in it?
Kindly tell me name of that powder(chemical)?

Ahora tienes que tener miles de cpu para esa cantidad de pelos de oro.

Watching here, BIG THUMPS UP from @POOR MINERS

[jacquesomersavard]

at 0.35 you have gold
how did you remove the casing from the ICs to gain access to the soldered gold wire
usually it is very difficult to open this kind of IC

i have 5 cpu thank you for sharing new friend LM repair vlog

[dreamcommunications]

Brother Good information 🙏😊
One old pc how much gold recovery?

[fungusenthusiast]

hey I've actually got a bunch of chips like the ones you have... maybe I should try this.

[Detalius]

Привет! Спасибо, получился очень красивый королек золота, просто завораживает!

[mutwarejaphetkado]

Hey
I have a question why do why go through with all procedures but at the end I end up without getting Gold please tell me the problem

[jotiramgaikwad]

Can these chemicals be purchased online?

[rl-khushboobsoni]

Srrr do u have book so i can also learn and start bussiness in large scale if not than any suggestions plz replysrr

[rasihdkuresi]

How to purity hydrochloric acid and nitric acid please sir

[BJLY]

Is it really gold or is it not necessary to answer

[agrippanyagwaya]

What is the name of that white stuff that you are burning together with CPU computer scrap

[prophetjah]

What is the name of the Gold melting machine
