Scanning Acoustic Microscopes (SAM) and Acoustic Micro Imaging Equipment (AMI) for Wafer, Circuit Board, Chip, Ceramic Capacitor, LED, and Advanced Material Testing

High-speed Scanning Acoustic Microscopy (FSAM) and Acoustic Micro Imaging (AMI) equipment allows detailed acoustic analysis in the ultrasound range from 5MHz to 300MHz, commonly used for non-destructive failure and material properties investigation of semiconductor chips, wafer & bonded wafers, MEMS, ceramic capacitors, OLED panels, industrial plasma, copper plates, fiber optic, special materials, and aerospace’s complex parts.


Supplied by a leading developer and manufacturer of acoustic microscopes and complex acoustic micro imaging (AMI) systems, our equipment is widely used for the analysis of defects in industrial products and semiconductor components and assemblies. Our SAM equipment is used for visualization of material interior by examining defects, voids, cracks, delamination in multilayered structures by a low time-consuming process.


High-speed SAM equipment significantly reduces takt time by incorporating advanced high-frequency and transducer technology with a high bandwidth Pulser Receiver and high-speed image processing software. Scanner module is equipped with four channels and enables detailed acoustic analysis in the ultrasound range from 5MHz~300MHz.


Equipment allows real-time ultrasonic 2D and 3D image output and an instant defect measurement report generation based on the defect location (XYZ coordinates) and sample size and type.


We offer both standard and custom equipment and contract SAM inspection services in our testing lab.

Scanning Acoustic Microscopy SAM, Acoustic Micro Imaging (AMI) Equipment Overview

Produced by a leading developer and manufacturer of scanning acoustic microscopes and complex wafer acoustic micro imaging systems, LPR Global’s scanning acoustic microscopes are used to conduct acoustic microscopy and acoustic micro imaging inspections. Developed with fast processing time and high-quality imaging goals in mind, we offer reliable NDT equipment for quality control and failure analysis of multi-layered electronic, microelectronic, aerospace, advanced materials, and life science components.


The Fast Scanning Acoustic Microscopes (FSAM) and Traditional Scanning Acoustic Microscopes (TSAM) feature a user-friendly interface, precise focusing features, and more data gates to easily check for cracks, inclusions, voids, and density variations in semiconductor wafers and advanced components at a wide range of transducer frequencies from 5MHz to 300MHz.


Different types of analysis are available in high-speed SAM, including A-scans, B-scans, C-scans, and through SAM analysis.

Our equipment uses a wide range of transducer frequencies, from 5MHz to 300MHz; with low flexibility providing higher material penetration; with higher frequency transducers, such as 200MHz and 300MHz, allowing higher image resolution useful once a particular area of the material sample has been isolated.


Our equipment combines high-quality imaging with simple analysis, allowing users to capture high-quality fully-focused images of various types of samples.


Advantages of LPR Global’s Scanning Acoustic Microscopy Equipment

Equipped with the fastest imaging technology, LPR Global’s Scanning Acoustic Microscopes SAM reduce takt time by up to 20 times by incorporating innovative high-speed scanning modules and improved equipment design. Scanner modules are equipped with four ultrasonic sensors mounted on the high-speed scanning module to ensure a short takt time, high throughput, and precise scans.


Another advantage is an option to incorporate four channels with 300MHz high bandwidth ultrasonic Pulser Receiver to allow fast processing time and high-resolution video output: 80MHz~300MHz. A full specifications package allows for 2D measurements, 3D profiling, and advanced measurements of samples.

Applications of Scanning Acoustic Microscopes

Scanning Acoustic Microscopes are commonly used for microelectronic and semiconductor component (circuit boards, chips, capacitors, wafers, LEDs, transistor chips, optoelectronics) NDT testing of failure analysis, product reliability testing, quality control, process development, R&D, counterfeit detection, and process validation. Main applications include semiconductor, microelectronics, life science, automotive aerospace, nanotechnology, and advanced materials.


Due to its ability to detect thin air gaps and anomalies, TSAM and FSAM models of Scanning Acoustic Microscopes are able to penetrate dense metallic materials useful in failure analysis, void detection, delamination inspection, crack detection, PCB anomalies of semiconductor components inspection; switches, sensors, power devices, and raw material SAM inspections.


Acoustic micro imaging systems are used at laboratories and at corporate level for low-volume production and R&D inspection; custom designed automated systems for larger scale inspection are also available.


Applications: semiconductor chips, bonded wafers, PCBs, MEMS, ceramic capacitors, electrical boards, display panels, battery cell, composite materials, and metals.
