AI Technical Summary
HDI circuit boards are prone to delamination during long-term use or in complex environments. Furthermore, the interlayer adhesives age under high temperature, humidity, or chemical environments, leading to delamination under mechanical stress. Existing structures need to improve their sealing and overall strength.
Multiple side guards are installed around the HDI circuit board, using a sealed structure and semi-screw connections. Silicone rubber is used as the sealing layer. The side guards and sealing structure improve the interlayer sealing, and the oblique screw connections enhance the overall strength.
It effectively reduces interlayer water seepage, prevents delamination, improves the overall strength and service life of HDI circuit boards, and has a simple structure that is easy to maintain.
