PCB reverse engineering (also known as reverse technology) is a process of printed circuit board design technology reproduction, reverse analysis and research of a target PCB board. It is also to deduce and obtain the design of the product's processing flow, structure, functional characteristics, and technical specification elements to produce products with similar, but not exactly the same ...
Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of the circuit board.

I'm surprised that additional emphasis hasn't been given to integrating these common functions on ready to use circuit boards with screw-down terminals. Share:
Every saturday I hit the yardsale circuit, always 50-60 miles. My main hunt is for gold, silver and ebay sellables. Over the last few months I have added computers, cell phones, brass, copper and copper wires. Well last saturday I asked about my usual things and a lady gave me (free) a box that had the guts to two computers.
"The best thing I extracted gold from was industrial video equipment -- a couple of ounces [up to 56g] per machine." Strip out the boards Place your circuit boards in a glass vessel.
On electronics that use gold for shielding (such as RF shielding) the gold can be very thin and instead of coming off in foils will separate into finely divided particles and will get lost in trash. Another cause for missing gold recovered this way is bad work habits.
You can make gold appear from something that isn't gold... And this is chemistry, not alchemy!ubscribe: All the best Eart...
The Canadian researchers' alternative is a solution of acetic acid and an oxidant — a nontoxic technique to dissolve gold, which is stripped from circuits in about 10 seconds, leaving intact copper, nickel, iron, and other metals in printed circuit boards. Dive insight: Traditional extraction costs $1,520 for one kilogram of gold.
According the NPR.org, there are enough precious metals in 200 cell phones to make a gold ring. The main use of gold in electronics is as the contact plating for switches, relays and circuit boards. This means that small amounts of gold are found in cell phones, calculators, GPS devices and computers, among other electronics.

The main circuit board from a Sony Betamax (Sony's short-lived laser disk player) is so big, it looks like a football field alongside most other circuit boards. Game consoles – Granted, they contain only a small amount of recyclable gold. But they were manufactured in such large quantities that they are still easy to find at garage sales ...
In this technique, the gold extraction is done under very mild conditions while the solution dissolves gold with the fastest rate ever recorded. "Gold is stripped out from circuits in about 10 ...
Step 3: Prepare Electronics for Gold Extraction. In this step, you will need to take your electronics device and pull out any PCBs from it. On the PCBs, look for gold color. When you find gold, strip all components off the PCB. If necessary, break the PCB in order to fit it into beaker.
Also, note that the circuit boards located inside a single newer laptop can contain gold worth around $15.00 to $25.00. Where Can You Take Your Scrap Metal For Money? The best way to make sure you're selling your scrap metal in a standard and responsible fashion, and for a good price, is to find a reputable, licensed scrap yard in your area.
pressure can also be felt in the PCB industry. Of course when making the PCB boards, we can find a lot of ways to reduce the cost, like changing the base material, changing the material of solder mask…By using all these methods, the prices of printed circuit boards can be reduced by 10% to 50%. But there is no "free lunch".
