UV Adhesive for Battery module harness reinforcement

Reinforcing battery module Flexible Printed Circuit Boards (FPCBs) poses several challenges, and addressing these challenges is crucial to ensuring the reliability and longevity of the battery module. Some common challenges associated with FPCB reinforcement in battery modules include:

Flexibility vs. Rigidity Balance: FPCBs are designed to be flexible, allowing them to conform to the shape of the module. However, reinforcing them without compromising this flexibility can be challenging. Balancing flexibility with the need for rigidity to enhance structural integrity is crucial.

Curing Time: UV adhesives, commonly used for FPCB reinforcement, cure rapidly under ultraviolet light. However, achieving uniform curing across the entire FPCB can be challenging, especially in complex or shadowed areas. Ensuring complete and consistent curing is crucial for the adhesive’s effectiveness.

Vibration and Mechanical Stress: Battery modules may experience vibrations and mechanical stress during use, particularly in automotive or portable electronic applications. FPCB reinforcement must withstand these forces to prevent delamination or damage to the circuit.

Understanding these challenges in battery module assembly, GLUDITEC provide the solutions with UV Adhesive – UV51P-660 to meet almost requirements in this applications.
