Photo Etched Parts That Give You High Precision And Tight Tolerances

With the advent of complex machines, one always feels the need for techniques that can cater to the most intricate of tasks

. Photo etched parts are the result of one such precise technique called photo etching. What makes this technique so preferred is the fact that it can give shape to the most complex design specifications.

It can create the most delicate parts with a high tensile strength. It is imperative to have the highest levels of precision because sometimes one part has to be duplicated for several purposes. This is why photo etching is so important and this also explains its high demand in the industrial sector today.

So how is photo etching done?

This process is also referred to as metal etching, chemical etching, chemical milling, machining etc. There are two types of etching-wet and dry. While wet etching deals with the process of dissolving the metal in a chemical-based solution, dry etching is all about shaping the metal with the help of vapor or ions. This is a very laborious process and requires high precision. This method is increasingly used for creating circuit board shields etc. Basically, photo etching is a combination of the basic etching techniques combined with photolithography. In this technique, various designs or patterns can be achieved with the reaction of enzymes and by using photo-resist substrates that are covered. With the use of certain chemicals, some desired colors can also be achieved in a photo etched part. These parts are used along with conductive foam.

Where is photo etching used?

Photo etched parts are used in sectors such as aerospace, military, automobile industries, communication, electronics, life sciences and biotechnology among others. In the aerospace and military sector, photo etching is usually applied as a high accuracy and low-cost tooling method. In the automobile industry, this can be used as for building some of the most intricate automotive parts that need high precision and tight tolerances. The electronic sector also makes rich use of these products as they create components such as a circuit board shield and RF shielding. You can also place your order on EMI product basis.

So when you are thinking of availing the services of the concerned person for photo etched parts always try and establish his credentials with enough ground research. Ideally, try to source your parts from manufacturers who also make products like conductive foam. You might also want to consider getting EMI products.
