[Case Study] Circuit Board Inspection for Aerospace and Defense Sector
TAKAYA APT Series
Please utilize Takaya's flying probe tester for substrate inspection in the aerospace and defense sectors.
In the aerospace and defense sectors, where high-quality standards are required, the use of flying probe testers streamlines the inspection of low-volume production boards. The flexible inspection flow, which does not require fixtures, enables quick turnaround times and ensures traceability, achieving both quality improvement and cost reduction. 【Implementation Results】 - Conducted full inspection of low-volume production boards, achieving quality assurance for products that require high reliability. - Responded to the stringent demands specific to the aerospace and defense sectors with a high-precision inspection flow. 【Challenges Faced by Customers】 Burden of Fixture Creation: Fixture-based testers require dedicated fixtures for each board, leading to excessive costs for low-volume production. The design and manufacturing of fixtures take time, making it difficult to respond to short lead times. Difficulty in Defect Detection: There is a risk of missing fine defects (hidden shorts, internal wiring issues) that are difficult to detect with only AOI or functional testing. Particularly in multilayer boards, visual inspections and standard power-on tests are insufficient for quality assurance. Traceability Requirements: In aerospace and defense products, it is necessary to record measurement results and inspection data in detail to ensure future traceability.

basic information
**Benefits of Introducing Flying Probe Testers** Flexible Inspection Without Fixtures: By using a flying probe tester, inspections can be conducted immediately without the need to create fixtures. Just by creating an inspection program, it can quickly respond to design changes and differences in product specifications. Supplementing AOI, XOI, and Function Tests: High-precision electrical inspections can supplement defects that cannot be detected by AOI or function tests (such as hidden shorts or connection failures). High quality standards can be maintained even for low-volume production boards. High Reliability Quality Assurance: Measurement values and inspection dates can be saved, making it easy to manage and search as traceability documentation. Inspection data can be utilized for future maintenance and quality assurance. Improved Cost Efficiency: Reduces the design and manufacturing costs of fixtures, optimizing cost performance even for low-volume production boards. Preventing the outflow of defective products reduces costs associated with re-inspection and corrections.
