Scanning Acoustic Microscopy (SAM) is an imaging technique that uses ultrasound waves for the structural analysis of materials. In this technique, a piezoelectric transducer sends ultrasonic waves towards the sample that get scattered, absorbed, or reflected at the media interfaces. We conduct SAM testing per the standard protocols under laboratory conditions to assess the internal structure and defects of products.... Read More
Scanning Acoustic Microscopy (SAM) is a non-destructive imaging technique that employs ultrasound waves to investigate the internal structure, defects, etc. It is most widely used for the identification of sub-surface imperfections within devices, assemblies, and materials that cannot be resolved by optical microscopy. Other Scanning Acoustic Microscopy applications include failure analysis, detecting hidden defects in elastic, biological samples, and inspecting voids and delaminations in semiconductors. Also called Acoustic Micro Imaging (AMI) and Scanning Acoustic Tomography (SAT), a lateral resolution lower than 30 μm and a vertical resolution of a few nanometers can be achieved in the laboratory with this technique.
In SAM, a piezoelectric transducer sends ultrasonic waves towards the sample that get scattered, absorbed, or reflected at the media interfaces. An image is created from the signal reflected by the sample. Air and water-filled blisters, delaminations, cracks, and micro-fillers can be differentiated at the sub-micron level by this technique.
Our testing labs carry out Scanning Acoustic Microscopy (SAM) efficiently to provide the best results to our clients based in the USA and other parts of the world. We at Infinita Lab perform not only routine tests, but also custom tests designed in our testing labs as per the client’s specific requirements.

Our network of material testing labs, spread across the USA, provides SAM imaging services to detect voids, cracks, and delaminations in a sample.
Scanning acoustic microscopy (SAM) is a non-destructive failure detection technique. It uses focused sound for imaging an object. It detects faults, delaminations, density changes, and other defects in materials.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
