There are different types of tip for tweezers in the electronics industry. You’ll often see statements like “Fine”, “Super Fine” or “Ultra Fine", etc. But how do we determine what “Fine” means for each given tweezer tip?
The specification to look for is CTM. CTM stands for Critical Tip Measurement, which is used to describe the size of the point on a pair of tweezers. The CTM is equal to the height and width of one of the tweezer’s two points.
For example, lets look at 5-SA-ET from Excelta. Its CTM is 0.0024" x 0.0039" (0.06mm x 0.1mm) which is listed on its datasheet as shown below.
