In order to gold-plate iPhone 6, engineers have to carry out dozens of different steps including disassembling, gold-plating, and re-assembling. The complicated level of each stage is different each other.
So far, there have been two different gold-plating methods all over the world: tank plating method, and brush plating method. Each method has its own advantages and disadvantages.
1. Tank plating method:
This method requires a large number of items which need gold-plating and large scale enterprises with high qualification at gold-plating like VinaTAB. Because it takes a high cost to invest a gold tank. Especially the gold tank must be regularly used, if not it can risk the quality of the gold tank.
Tank plating method: engineers will dip all items which need gold-plating into a tank of gold; the quality and the beauty of products depend on the time as well as technology and technological secret of each company.

The advantages of the tank plating method are that the surface of gold-plated layer is even, bright and beautiful; especially by this method, multiple parts are plated at one time. Furthermore, VinaTAB engineers can be plated big-sized products such as Rolls-Royce Phantom supercar, big Buddha statues, 2-3m items…
2. Brush plating method
This method is quite popular in Vietnam and around the world. It is very suitable for small and medium scale enterprises, particularly for enterprises which have a small number of gold-plated products. With this method, the enterprises do not need too much capital to invest as well as the cost of gold plating.
Small and medium enterprises only need to invest a small amount of capital to purchase items and gold-plating solutions. However, the disadvantage of this method is that the surface of gold-plating layer is not adhesive and uneven.
