The Nature of Etching
Etching is a technique that uses the corrosive action of chemicals and reactive gases to process surfaces. It is often carried out on metals like iron, copper, and aluminum. The technique, also referred to as “chemical milling,” enables processing etchable materials into diverse forms. Apart from metals, etching also finds application in glass decoration and plastics plating.
The Evolution of Etching
Etching, developed in antiquity as a technique for copper engraving, is now largely used for processing printed-circuit boards. These boards, widely used in the electrical and electronics industries, utilize copper foil to create electrical paths for connecting circuit elements and ICs. The etching process is utilized to fabricate these complex and precise electrical paths.
Wet Etching and Its Equipment
Among the etching operations essential to the manufacture of printed circuit boards, wet etching stands out as highly productive and cost-effective. Wet etching refers to processes that use liquid chemicals to remove materials from samples. When selecting equipment for wet etching, considerations include the type of chemical, the size and shape of the sample, and the cleanliness group.
Types of Wet Etching Equipment
There are several types of equipment necessary for wet chemical etching metal processing. These include cleaning lines, painting and drying lines, exposure lines, developing lines, etching lines, and stripping lines. Companies like RENA NA and Manz AG offer a range of wet processing equipment integrating wet chemical etching, cleaning, and drying processes.
In conclusion, wet etching is a vital process in the manufacturing of printed circuit boards. Understanding the intricacies of wet etching and its equipment can lead to more efficient and effective production processes.
