In the modern world, the demand of gold plating service is no more limiting merely within jewelry field but has reached even the space applications. Basically, gold plating procedure can be accomplished through electro-deposition or electroplating and electroless process to effectively fuse a layer of gold on an object or another metal body when both ends are being electrically charged. Among various types of gold plating services, the popular most are soft/ pure gold plating, and bright/ hard gold plating. The writing here focuses on the types and various uses of gold plating.
Soft, Pure Gold Plating
Soft, pure gold plating is an outcome of special electrolyte bathing which needs to be free of any kind of infectivity. Its Knoop solidity ranges among 60-85 and it can be wire bonded or soldered. This makes it highly sought after in semiconductor and electronics industry. With highest class of conductivity it’s the first choice for plating internal foils of printed circuit boards.
Hard, Bright Gold Plating
With Knoop hardness ranging 120-300 as well purity of 99.7- 99.9%, hard, bright gold often include nickel or cobalt. Since the products interfere with die bonding, they cannot be used in semiconductor applications. However, ideal to be used for connector edges and Printed circuit boards.
What Makes Gold Plating Service Increasingly Demanding?
Gold showcases exceptional electrical conductivity and facilitates with its highest class of the electrical current transmission ability. They won’t melt like many other metals when current passes through and remain unaffected, owing to its heat-resistant properties. This makes gold a matchless choice for electronics industry especially for PCB and integrated circuit ICs designing. Gold plating has enhanced solderability too, that helps electronics.
Gold plated items reacts the least among all metals to moisture and oxygen exposure with its high anti-oxidative feature. This makes it anti-corrosive while it can sustain well in high temperature zone opposed to its counterparts.
Even if, the base metal is inexpensive, be its silver, copper, tin, or even aluminum, with gold plating they appear similar to solid lustrous piece of gold jewelry.
Gold is highly malleable making them easy to be deposited in any form of substrates with its great bonding feature.
Applications of Gold Plating Service
The foremost industry that appears in the list of gold plating service users is undeniably electronics. Why it’s so? Because, it boasts unbelievable conductivity attribute as well as heat-resistive property, which is essential in flawless transmission of circuit boards. At the juncture, when human civilization virtually moves on electronics, just try to estimate the significant of gold plating! Aside from PCBs, it is used for profuse electronics elements like ICs, connectors, semi-conductors, transistors and more.
No wonder, gold plating is most wanted in jewelry industry for plating metals like silver or bronze that gives the base metal an appearance equivalent to gold ornaments. This is indeed a great choice for ornament loving women who cannot afford gold and can meet their desire with minimal investment.
With the flourishing trend of cosmetic dentistry, gold plated crowns, denture, dental bridges to false teeth are in great demand to stylish individuals.
Gold plating has rising demand in microelectronic, microsystem and optoelectronic industry all over the globe. The primary ground of this rise lays in the reliance of gold in terms of its high thermal and electrical conductivity aside from its properties like superior corrosion resistance, bondability and solderability standard that the industry look for.
As specified by NASA, gold plated mechanisms are used to thermally control spacecrafts or rocket instruments, given that it has 99% reflectivity property in infrared wavelengths. They are equally used in aviation to protect the intense solar radiation.
