Ultrasonic phased array is a combination of ultrasonic probe wafers, by a number of piezoelectric wafers according to a certain distribution arrangement, and then according to the pre-specified delay time to stimulate each wafer, all the wafers emitted ultrasonic waves form a whole wave front, can effectively control the shape and direction of the emitted ultrasonic beam (wave front), can achieve ultrasonic beam scanning, deflection and focusing. It provides greater ability to determine the shape, size, and orientation of discontinuities than a single or multiple probe system. Ultrasonic phased array detection technology uses multi-element transducers with different shapes to generate and receive ultrasonic beams. By controlling the different delay time of the pulses transmitted (or received) by each element in the transducer array, the phase relationship of the sound wave when it arrives (or comes from) a certain point in the object is changed, and the direction of the focus and sound beam is changed, so as to achieve ultrasonic beam scanning, deflection and focusing. Then the method of combining mechanical scanning and electronic scanning is used to realize image imaging.
Our products use a two-dimensional matrix array probe, piezoelectric wafer is arranged in a rectangular shape, can get two-dimensional images of defects, in the industry has been widely used.
High inspection cost
Slow detection rate
Untraceable data
The operation of ultrasonic equipment is difficult and difficult to understand.
When detecting solder joints of different diameters in ordinary ultrasonic equipment, the probe is often selected and replaced
The weld core diameter cannot be accurately measured
This equipment is an ultrasonic phased array solder joint quality inspection equipment composed of 121 ultrasonic chip probes, which has the following characteristics:
1. Dynamic image display (Ultrasonic C-scan)
2. Each welding spot image is analyzed and imaged from more than 700 scan data sets
3. 11*11=121 elements make up the ultrasonic phased array probe
4 Probe effective detection area 9x9/11*11mm2, frequency 12/20MHz
5. Smaller and denser detection chips, and more optimized algorithms make welding spot imaging finer and more accurate
6. Easy to use user interface, easy to use with simple training
7. End probe bubble design to fit irregular welding spots, more coupler saving (bubble and hard wedge can be freely replaced, no need to change the probe)
