Without effective aging tests before mass production, PCBs are likely to bring hidden thermal stress defects and component compatibility issues into batch production, leading to huge losses such as rework and recalls. For fields with strict stability requirements like industrial control and IoT, “verifying reliability before mass production” is an indispensable key link. With hands-on experience serving over 800 clients, Fumax has built an aging test system tailored to mass production scenarios, enabling feasible verification of PCB reliability before mass production and intercepting potential failures in advance.
Our core advantage is “scenario-specific customized test solutions”. According to PCB application scenarios (e.g., high-temperature industrial environments, high-humidity outdoor equipment), we design targeted test conditions: high-temperature aging test (85°C for 72 consecutive hours), temperature-humidity cycle test (-40°C~125°C for 50 cycles), electrical stress aging test (continuous operation under full-load conditions), fully simulating extreme situations in long-term use. For example, the customized aging solution for an automotive electronics client detected hidden heat dissipation deficiencies of power chips through 100-hour high-temperature + vibration composite testing. After layout optimization, the batch failure rate dropped to 0.8%.
A scientific test process ensures verification effectiveness. First, select representative samples (covering components from different batches and production stations). Second, integrate AOI inspection and FCT (Functional Test) to real-time monitor parameter drift, solder joint failure and other issues during aging. Third, use X-Ray inspection to detect hidden defects and form a complete report including failure points, causes and optimization suggestions. Finally, feed test conclusions back to design and production to update DFM specifications.
We reject “standardized test templates” and insist on adapting to different customer needs with experience: low-to-medium volume clients focus on key performance verification to control test costs; mass production clients increase sampling ratio to ensure batch consistency. To date, PCBs verified by Fumax’s aging tests have an average first-pass yield of 98.5% in mass production, reducing customers’ rework costs by over 60%.
At Fumax, we believe aging testing is not an “additional cost” but a “mass production guarantee”. Leveraging years of experience, we make testing more accurate and practical, helping your PCB mass production journey avoid detours.
