[Case Study] High-Density Substrate Inspection in Semiconductor Manufacturing Equipment
TAKAYA APT Series
Please utilize Takaya's flying probe tester in the high-density substrate inspection process for semiconductor manufacturing equipment.
High-precision inspections compliant with IEC60384-1 are possible. The characteristics of electronic components such as fixed capacitors are guaranteed according to international standards, achieving improved quality for high-density boards. We flexibly respond to design changes and prototypes, providing cost-effective inspection solutions. 【Implementation Achievements】 - Conducted inspections of high-density mounted boards, achieving quality assurance tailored to precision boards. - Enabled inspections compliant with the IEC60384-1 standard (performance standards for fixed capacitors), ensuring product quality in line with international standards. 【Customer Challenges】 Narrow Pitch Between Components: In high-density boards, the space between components is extremely narrow, making physical contact difficult with traditional jig-based inspections. There is a potential decrease in inspection accuracy, especially in narrow pitch areas below 0.2mm and with high pin count components. Need for Compliance with Standards: As compliance with international standards represented by IEC60384-1 is required, a system that reliably implements inspection items based on these standards is necessary. It is particularly important to measure the characteristics of fixed capacitors and special components accurately and quickly. Limits of Inspection Coverage: In designs where the number of test points has decreased, there is a risk of reduced inspection coverage due to insufficient physical access.

basic information
**Benefits of Introducing Flying Probe Testers** **IEC60384-1 Compliant Testing:** Using flying probe testers, inspections are conducted in accordance with the requirements of IEC60384-1 (such as capacitance values, withstand voltage, leakage current, insulation resistance, etc.). Characteristic testing of fixed capacitors and other electronic components based on international standards is possible. **Narrow Pitch Compatible Flying Probe Testers:** Probing with a pitch of 0.15mm is possible, complying with the stringent measurement standards of IEC60384-1. High-precision measurement technology covers the inspection of narrow pitch and multilayer boards. **High Flexibility:** No fixtures are required, allowing for rapid adaptation to design changes or modifications in the manufacturing process. Inspections can be conducted in a short period even for small production runs or prototype boards. **Improved Reliability through Compliance with Standards:** By adhering to IEC60384-1, product reliability in the international market is strengthened. Guaranteeing compliance with standards enables quality assurance that meets customer requirements. **Enhanced Inspection Coverage:** Detailed inspections are possible, including internal wiring of narrow pitch components and multilayer boards. Detection of minute defects (such as shorts, opens, and abnormal resistance values) is achieved.
