This article is primarily intended for beginners starting their journey in the world of stand modeling. People who are just starting in our wonderful hobby often have a question - what is this mysterious "etching photo" / gold details on the model, etc. Today we will try to briefly talk about this technology in the framework of modeling.
Micro-holes mesh etching (photoetch or PE for short in English) is a metal processing technology that came from the field of electronics and jewelry. Without going into the jungle of chemistry, the process is easy to describe as something like this - a photoresist composition applies to a thin sheet of metal, and then the metal is immersed in acid.
Those areas that cover with the composition remain unharmed, while others are corroded (etched) to a certain depth or through and through. Due to this, the most varied small patterns obtain on the details.
The fact is that the plastic molding technology, even the most advanced one. It does not allow casting various parts with the required detailing or thickness. Various nets and grilles will never be through, the fenders will not have a large-scale thickness, there will be no large-scale crosshair in the plastic, etc.

This is where photo-etching comes to the rescue.
Photo-etched mesh on the Gaz-Tiger model. It is not realistic to cast through the mesh in plastic, and a nylon mesh looks worse than a Micro-holes mesh etching part.

Some manufacturers include photo-etched parts in their kits, but more often these kits are sold separately from the model. Now they are produced by a great variety of companies, ranging from the famous Czech Eduard and ending with our company.
Photo-etching is done from a wide variety of metals, but most often from brass, which has a “golden” sheen, which makes it seem to beginners that gold parts glue to the model.
Micro-holes mesh etching metal.
When working with photo-etched sets, a certain amount of experience is required, since many parts are made in the form of reamers, which must first be bent to the desired shape. In addition, photo-etched parts are often put in place of native plastic parts that need to be cut from the model in advance.
Micro-holes mesh etching parts glue to the model on cyanoacrylate (super-glue). Photo-etch parts can also connect by soldering, which ensures high strength of parts joints but requires skills in working with a soldering iron.
To work with photo-etching, you need a model knife, super-glue, a file, and tweezers. In the future, to work with more complex sets, it is worth purchasing a special bent for photo-etching, which allows you to bend etch parts using clamps, which will greatly facilitate work with long metal parts and when assembling complex sets.
It is worth cutting off parts from the board with a knife. If the part is very small, it is worth sticking adhesive tape on the back of the Micro-holes mesh etching part so that the cut part does not fly away under the table.
After separating the part, the cut site should process with a file. And then, using tweezers, bend the part, if necessary. Most often, fold lines etch on parts. But be careful and careful, if you bend the part in the wrong direction and try to bend it back, it will most likely break along this very line.
You can see the lines along which you need to bend the part during assembly.
If the photo-etching is hard and does not bend well. It is worth burning it over a candle / lighter flame. After that, it will become noticeably softer.
When painting, Micro-holes mesh etching parts prime. Ordinary soil for models is also suitable, but large parts, like the same screens on armor vehicles, sand with fine sandpaper. And degree with a cotton swab with alcohol to increase adhesion. Yes, all this colorful and shiny splendor fades under the paint, no matter how sorry it is to paint it.
Often, such sets have a layer of glue on the seamy side. Working with such kits is simple - just install the parts in their place after painting the plastic parts.
For aviation models, dashboards make from photo-etch parts and transparent film, with device prints on them.
When assembling such a dashboard, you must first paint the photo-etched board in the desired color. Then paint the film with the device white from the wrong side. And at the end cut it along the contour and glue the etched part from the wrong side.
As a result, the instrument scales will be visible through the holes in the Micro-holes mesh etching part.
It is not necessary to common all the parts from the photo-etched kits. Often, in the pursuit of filling the set, etching manufacturers make in the metal those parts. These parts’ reality should not be flat, but bulky. Most often this applies to various wiring, handrails, etc. It is better to make such details yourself, from the wire.
Conclusion
The Micro-holes mesh etching parts can often be very small. For their installation, it requires to seriously "grind" the model, common of which the Micro-holes mesh etching part may end up being less accurate than the native plastic one.
