Acoustic inspection systems use ultrasound to examine internal interfaces in electronic components and packages. Scanning acoustic microscopy can reveal features such as delamination, voids and bonding irregularities that may be difficult to assess with surface inspection alone.
The technique is particularly relevant to layered structures, encapsulated devices and bonded materials. Acoustic response varies at material interfaces, allowing suitable systems to form images of internal conditions. Sample compatibility, access and the required coupling method must be assessed before choosing this approach.
Resolution, penetration and inspection depth need to be balanced for the package being examined. A consistent scanning setup and appropriate reference samples help analysts interpret the results. Acoustic inspection may complement X-ray or other methods when different types of internal defects need to be investigated. Sample preparation and handling should preserve the condition that the analysis is intended to assess.
