AI Technical Summary

Technical Problem

Conventional printed circuit boards (PCBs) in data storage devices are susceptible to physical damage, such as scratches and cracks, which compromise the electrical connection and reduce the lifespan of memory devices, and conductive traces degrade over time, leading to data errors and device malfunctions.

Method used

Incorporating repairable dielectric materials for solder masks and repairable conductive materials for traces that can be selectively repaired using heat or voltage, respectively, allowing the PCBs to self-repair or be automatically repaired.

Benefits of technology

Enhances the durability and reliability of PCBs by enabling quick and cost-effective repair of damage, reducing the need for costly replacements and improving the performance and lifespan of electronic devices.

Abstract

The present invention provides a PCB including a solder mask and / or conductive traces that can be repaired quickly and cost-effectively. [Solution] A printed circuit board includes at least one solder mask formed from a repairable dielectric material and / or a conductive trace formed from a repairable conductive material. Thus, the solder mask and / or conductive trace can be selectively repaired. The repairable dielectric material may flow when heated to a repair temperature. The repairable conductive material may flow when a repair voltage is applied. As with methods for repairing the solder mask and conductive trace of the PCB of an electronic device assembly, an electronic device assembly is also disclosed.
