Abstract

This project focuses on the design and fabrication of a compact, cost-effective humidity chamber for evaluating solder joint reliability under controlled environmental conditions. Commercial humidity chambers are often expensive and bulky, limiting their accessibility in academic and small-scale research settings. To address this, the project developed a prototype using PVC foam board and low-voltage components such as a 5V humidifier, 12V fan, and thermo-hygrometer. Design selection was guided by tools like the Pugh Matrix, emphasizing portability, ease of fabrication, and material efficiency. The completed chamber successfully maintained internal humidity between 77% and 79%, demonstrating its ability to simulate consistent environmental conditions for small-scale solder testing. The outcome offers a practical solution for low-budget research environments and contributes a functional, scalable tool for studying humidity-related degradation in electronic components, with opportunities for future upgrades through automation and data logging.
