Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of epoxy boards, it is recommended to clarify key technical parameters such as thickness, temperature resistance level, and dielectric strength based on actual application scenarios (such as electrical insulation, mechanical support, etc.) to avoid performance redundancy or insufficiency.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable epoxy board supply and after-sales service guarantee.
  • When applying epoxy boards in industrial equipment or PCB substrate fields, attention should be paid to whether their thermal expansion coefficient and mechanical strength meet the long-term use requirements in high-frequency or high load environments.
  • There are differences in chemical corrosion resistance and flame retardancy among epoxy boards of different specifications. It is recommended to compare the horizontal parameters with specific usage environments (such as chemical equipment or rail transit components) before procurement.
