Guide To Choosing The Right Encoder For Semiconductor Machinery

Digital encoders are vital for a wide variety of industries. Be it linear encoders, rotary encoders, angle encoders or other types of specialty encoders, each serves its unique purpose. The semiconductor fabrication industry also requires encoders for myriad position feedback applications. But how to select the right encoder for semiconductor machinery? This blog aims to answer this question in detail.

How To Choose The Ideal Encoder For Semiconductor Machinery?

First and foremost, to select the right digital encoder, it is important to consider the following factors:

- Environmental factors acting on the encoder, such as temperature, vibration and vacuum.
- Mechanical or spatial constraints that impact encoder mounting.
- Level of accuracy/precision required.
- Speed of operation of the encoder.
- Level of allowed interpolation error.

With these factors taken into consideration, the selection can be further narrowed down:

Specifications

If the above-mentioned factors are considered, then choosing a digital encoder can be narrowed down easily. For instance, if the environment is a vacuum and there are spatial constraints, then a specific type of encoder is preferred. Similarly, if the encoder has to operate in a vacuum but there is an emphasis on precision, then another variation of the encoder has to be considered. 

Encoder Graduation

Another key factor to consider is the encoder graduation. Whether it is a linear encoder or a rotary encoder, graduation is important as it not only ensures proper performance but also keeps the quality consistent across an extended time period.

Go For Trusted Encoders

Semiconductor machinery is selected for its accuracy, and this is ensured by getting it thoroughly tested. A similar standard is expected for encoders used in these machines. Therefore, only stick to encoder brands that are known for their excellent quality and rigorous testing.
