  • Ultrasonic Processing of Fabric and Film
    Fabrics and films used in the nonwoven, medical, filtration, textile and packaging industries can be processed using ultrasonic energy. Several of the common techniques applied are ultrasonic rotary/continuous bonding, ultrasonic slitting, plunge and traversing. Ultrasonic bonding assembles two
  • Intro to Ultrasonic Phased Array
    ultrasonic tests that include weld inspection, bond testing, thickness profiling, and in-service crack detection. This paper provides a brief introduction to how phased array systems work and how they can be employed in industrial ultrasonic nondestructive testing.
  • The Basic Principle Of Ultrasonic Assembly
    force, creates frictional heat at the plastic components' mating surfaces (joint area) so the plastic material will melt and form a molecular bond between the parts. The following drawings illustrate the basic principle of ultrasonic assembly...
  • Guide to Ultrasonic Plastic Assembly
    Ultrasonic plastics assembly is the joining or reforming of thermoplastics through the use of heat generated from high frequency mechanical motion. It is accomplished by converting electrical energy into high frequency mechanical motion (vibrations) that creates frictional heat at the joint area
  • Understanding And Caring For The Heart Of Your Ultrasonic System
    energy (or heat) at the contact point of the two parts. The heat melts a molded ridge of plastic on one of the pieces and the molten material flows between the two surfaces. When the vibration stops, the material solidifies forming a permanent bond. A basic ultrasonic probe consists of -. 1. A housing
  • Introduction of Wedge Capillary for Wire Bonding
    Wire bonding is currently the mainstream connection method for semiconductors packaging. Commonly used wire bonding welding methods include thermocompression welding, ultrasonic welding and ultrasonic thermocompression welding. Wire bonding can be categorised as ball bonding and wedge bonding
  • Ceramics Capillary for Copper Wire Bonding
    Wire bonding is to weld the two ends of the lead to the chip pad and the lead frame respectively in a certain environment by means of thermal ultrasonic pressure, so as to realize the connection between the internal circuit and the external circuit of the chip. Up to now, the lead metal materials
  • Servo Ultrasonic Welding Slashes Energy Costs in Automotive Application
    In addition to delivering 87% energy savings over pneumatic systems, the servo-driven ultrasonic welder also improved bond strength.
