Creating Etched Components By Using Different Types Of Etching Process

It is necessary to etch the thin films as a substrate to design a functional metal part on it. Normally, two types of etching processes are used to create such etched components, wet etching, and dry etching.

Wet etching

In this process, etched components can be created by immersing the masked substrate into a chemical solution to dissolve its unmasked part. It is the simplest and most cost-effective technology used for creating precision metal parts. You only need a container and etching chemical to etch the required material precisely by dissolving the material in the liquid solution. However, you will have to find a material that can be masked on the design of the metal part of your substrate so that its unmasked part can dissolve without dissolving the mask in the liquid chemical and etch the metal part precisely. Moreover, you will have to choose etching chemicals according to the type of material you want to etch.

When to use a wet etching process?

Wet etching can be the best method to etch substrates made of thin metal sheets or films. You can find various combinations of etching chemicals and masking materials to choose from as per your suitability. Though other etching processes like isotropic and anisotropic processes can also be used for etching substrates made of thin metal plates but there is a risk of undercutting or overcutting the layer of the mask which can be devastating for the idea creating precision etched components.

Dry etching

The technology of dry etching can further be divided into three categories- RIE or reactive ion etching, Sputter etching and vapor phase etching.

In RIE, several gasses are introduced in a reactor in which the substrate to be etched is placed. The mixture of gases is stricken by plasma by using the power of RF to break the molecules of gases into ions. These ions react with the surface of the substrate when accelerated to form another gas which can be used for reactive ion etching.The sputter etching is RIE without the reaction of ions. In sputter etching, these ions can etch the material to be etched without any chemical reaction if the energy of the ions is high enough.The equipment used for Vapor phase etching is simpler than the equipment used for RIE. The substrate to be etched is placed in this process in a chamber containing one or more gases to dissolve the substrate due to chemical reaction with the molecules of gas.

Such things make the process of dry etching very complicated as you have to adjust several parameters for balancing physical and chemical etching.

When to use a dry etching process?

Though dry etching is a costlier process than wet etching still you can use it to create etched components if you are worried about the resolution of the structure of thin film or you want deep etching in the vertical sidewalls of the substrate.

Thus you can use different etching methods to produce etched components according to your requirements and budget.

How to Monitor Breathing

As an athlete in the early stages of training you have decided to keep track of your vitals. They are important – they tell you how well your body is doing and how it is adapting to the rigors that you are putting it through. One of the things that you want to monitor is your breathing. Breathing rate is important because it tells you not just how hard you are working your heart, but how hard you are working your muscles too. The harder you breathe the more oxygen you send to your muscles which translates into bigger and stronger musculature over time.
Keeping track of your breathing is not as easy as buying a device. You need to know how to collect the data so that over time you can form a picture that informs you about your health. When you shop for a device you should be looking for one that just monitor how many times you breathe in and out – it should show you overall body performance and improvement in a given period.
The best way to monitor your breathing is to do it both when you are active and inactive. You can start by wearing your device as you sleep so that you can see how many times you breathe in and out when you are at rest. You can then look at how you breathe when you go about regular tasks about the home, when you are shopping, when you are at work and so on. This data will provide a valuable baseline to compare with the breathing data that you collect when you are working out.
Equivital can provide you with one of the best breathe monitoring devices in the market. You can see what they have to offer on their website,

How To Use A Heart Monitor For Maximal Health Benefits


If you are looking to improve your health then you need to greatly consider getting a heart monitor. A heart monitor can help you with a number of things. This ranges from just taking a simple heart rate to analyzing complex patterns with your hearts intrinsic activity. The use of this information can help to do a number of things including simple maintenance, diagnosis of diseases, and prevention of diseases. While these are greatly beneficial to health, few people use them the right way. This is usually not an issue of compliance, but an issue of a lack of education on how to properly use a heart monitor for maximal health benefits. To ensure maximum effectiveness please refer to the simple steps below that will provide long-term health benefits and potentially life-saving information.

Steps For Proper Heart Monitor Use

  • Learn Proper Placements
  • Monitor For Abnormalities
  • Determine Appropriate Response To Findings

Step #1 – Learn Proper Placements

The first and most important step is to learn the proper placements of the electrodes or the sensor. This will ensure that the data is highly accurate and reliable. Without proper placement, you will not be able to gather any information about what is actually going on internally. This applies to both finger sensors and things as complex as ECG sensors that use chest electrodes to gather very detailed information.

Step #2 – Monitor For Abnormalities

Once you have figured out how to operate your heart monitor you need to learn how to read the information for abnormalities. The first thing that usually indicates heart abnormality is a drastic change in heart rate or in the blood oxygen levels. When heart rate goes above 140 beats per minute or the partial pressure of oxygen drops below 92%, then you should think an abnormality is going on.

Step #3 – Determine Appropriate Response To Findings

Once you have determined that there is cause to think there is an abnormality, the next step is to asses the situation to be able to enact the appropriate response. Sometimes things are very simple and all you have to do is adjust something at home. Other times things can be serious enough to require emergency medical care. Either way, the use of this greatly impact health in a positive way. By using these steps you will be able to get full use out of your heart monitor for maximal health benefits.
