Palladium vs. Gold Plating: Which Option to Choose ...

Both palladium and gold are deposited onto a surface using an electroplating process. This process works in much the same way as most other metals: Cleaning: The object to be plated is first examined for cleanliness and put through a thorough cleaning process. Any stains, marks or other imperfections on the surface of the object act as a barrier to the electroplating process

Amalgamation: Using Mercury to capture fine gold,

2014-6-22  Occasionally, the amalgamation process does not collect as much gold as anticipated. This type of result usually occurs when the formation of amalgam is inhibited due to poor contact between the gold and the mercury. This happens most commonly when the gold is very fine or when it is tarnished by a surface or film.

Solder Paste Process Problems and Analysis - AiPCBA

They are formed around components with extremely low stand-offs, such as chip capacitors. Solder beading is caused by flux exhaust. During the preheating phase, this exhaust effect exceeds the cohesive force of the solder paste. The exhaust promotes the formation of isolated agglomerates of the solder paste under the low-gap components.

How Is Platinum Extracted From a Catalytic Converter?

Loosening and then removing these bolts with a simple socket wrench allows for a catalytic converter to be pulled (removed) from a vehicle. If time is of the essence, a cutting torch can be used to simply cut the metal attachments linking a catalytic converter to a vehicle's exhaust system, allowing for fast catalytic converter removal.

How Is Platinum Extracted From a Catalytic Converter?

The elements that ignite incoming exhaust gases that pass through a catalytic converter, otherwise known as catalyst elements, look like chunks of burnt charcoal. These catalyst pieces, which become white-hot in response to incoming exhaust gases, are coated with platinum to speed up the rate at which they heat up and burn exhaust gases.
