Photoetched parts involve very small metal parts that are produced by means of the photochemical process from usually a sheet of thin metal. This process involves etching a metal extensively or in some cases etching the surface of the metal alone but with a very high precision in order to get minute and exact flat parts of any shape and form. Note that, with the aid of some special tools, metals can be photo-etched at home. And also bear in mind that, photo-etching parts are not all the same, in fact, it’s made of different materials like steel, nickel, brass and it also has diverse thickness level too. Photo-etched microelectronic parts are usually shiny and can at times look chrome plated, flat and dull. It might take any of the mentioned forms depending on the photo-etching process it has undergone. However, you can get regular photo-etched parts that can be attached to frames. This type is quite easier to make and also remarkably less expensive than the rubber-backed parts. But note that, it’s a lot harder to work with compared to the rubber-backed parts that are far easier to remove, very expensive and also difficult to come across.
Ever thought about rotor and stator lams for motors? The metal etching is that perfect component to fill in the quantities required, whether small, mid range or large quantities.
In addition, the remarkable thing about chemical etching process is the fact that it leaves no burrs and impacts, and also no mechanical or thermal stress too.
When it comes to QFN and LD-MOS leadframes, photo etching is guaranteed to do the perfect magic and not just on it alone but also on other custom platforms too.
As a result of its amazing low attenuation loss, the QFN otherwise known as “air-cavity” packages are perfect for use in RF and microwave communications applications. Due to its complex and also fragile designs, the leadframes are just perfect for the capabilities of chemical etching.
Photo-chemical etching with common alloys like Kovar, Invar, F-15, and others can also produce flat and step lids for airtight sealed electronics packages.
The reason why chemical etching is greatly admired by many is the fact that, it’s a very fast and also economical means of producing a wide range of both simple and intricate enclosures and also barriers to electromagnetic and radio frequency emissions.
Choosing a reliable supplier.
When choosing a supplier, go for a reputable manufacturer that has a good record of manufacturing photo-etched microelectronic parts for different industries such as electronic, medical, aerospace, military, automotive, consumer & micro-electronic, and much more. Go for a supplier whose photo-etching process and machines that can accommodate various composition of metal alloys which will serve your specific industrial purpose. And finally, go for a manufacturer that is familiar with design challenges.
In conclusion, choosing a supplier of such caliber will guarantee you top notch quality on products and also after sales services.
