zero-back.Note the motion module in the diagram, where the servo motor + encoder + Ball Screw module is used to form a semi-closed-loop system, or a linear motor + grating ruler (or servo motor + encoder + Ball Screw module + Grating ruler ) to form a fully closed-loop system.If the ball screw module, need to understand the concept of lead , that is, the screw rotation of the module forward the distance, the common lead is 10mm,20mm.If you are using

sealed, and will not affect the normal welding. Pads to fill the tear drops: when the wire with the pad connection is thinner, the connection between the pads and the line is designed to be a teardrop-shaped, the advantage is that the pads are not easy to peel, but the line and the pads are not easy to break. Adjacent pads to avoid a sharp angle or large area of copper foil, into a sharp angle will cause the wave soldering difficulties, but also the danger of bridging, large area of copper foi

The screen size increases to show more content, The density of the touch screen control should not be too large, otherwise it is inconvenient to click . Each mobile phone and PC operating system has a recommended value for the clickable area: IPhone: The minimum value is 29 x 44px. Windows Phone:9mm/34px, minimum 7mm/26px, minimum distance between elements 7mm/26px, and visible area of the element is 60-100% of the click area.

The hardness is 110hv to 130hv and the curvature radius is 10mm, along the magnetic stripe. 5 N of the external force often move times, and then read the data, the signal range must be within the range specified

like? Surface RT and iPad (Note: ipad2 in the figure) thickness comparison. Because the thickness of ipad2 is only 8.8mm, it is obviously thinner than the surface RT. However, the latest ipad4 thickness is 9.4mm, which is equal to the 9. 3mm thickness of surface rt. Comparison of surface RT and Nokia Lumia 800 thickness. Surface rt is less than 10mm thick than Lumia 800, you can see that Lumia 800 back bulge. Comparison Between Surface RT and Nokia L
