1. What is MFC? - MFC stands for Mass Flow Controller and refers to a mass flow control device as the term implies. - The mass flow unit of the MFC is generally SCCM or SLM*. * SCCM and SLM are units representing the flow rate in the standard state, and please refer to the link below for more information. https://ysbusy.tistory.com/62 01. What is SCCM & SLM? Why do we use this unit? (Including e..

In this posting, we will look at Geometric Tolerance(Geometric Dimensioning and Tolerancing, GD&T), especially Flatness and Parallelism (definition, reason for use), and distinguish between the two concepts. (Note that the Geometric Tolerance is basically a symbol used in the drawing of the part.) 1. What is a Flatness? A. Definition. - Tolerance indicated in the drawing how flat the plane of th..

1. What is SCCM & SLM? A. What is SCCM? (Standard Cubic Centimeter per Minute) Just like the term, It is a unit representing 'how many cc per minute the gas flows in the standard state'. (1cc=1㎤) In this case, the standard state means 0 degrees Celsius and 1 atm. (1 atm = 1 atmosphere = atmospheric pressure) That is, 1000 SCCM in the standard state means that 1000cc of gas flows per minute. B. W..
