Small Precision Tools Capillary Profiles Affecting Ball Bond

Capillary Profiles Affecting Ball Bond. Hole Size (H) is determined based on the Wire Diameter (WD) to be used in a given application. Typically, the ratio is around 1.2X to 1.5X of the WD. A smaller hole size ratio is necessary for ultra-fine pitch application to compensate for the smaller chamfer diameter

Wire Bond / Ball Shear Application Note

2018-1-5  Ball bonding is the process in which pads are connected onto a die and leadframe (or substrate) using very fine diameter wire. The basic steps of ball bonding include the formation of: the first bond (normally on the chip), the wire loop, and the second bond (normally on the substrate). The wire-bonding cycle is shown in Figure 1. P.8 Figure 1.

Ball Valves Selection Guide: Types, Features, Applications

Ball Valve ApplicationsFeaturesSelection of Ball ValvesBall valves are commonly found in flowing systems on ships, fire safe protection servicesand chlorine manufacturers. They are not recommended for use in pharmaceutical, bioprocessing, or food and beverage applications because they cannot be cleaned easily. Exceptions can be made for chemical or non-sterile applications See GlobalSpec's Valve Application and Valve Standardspages for more information.在globalspec上查看更多信息
