FR4 Epoxy Board vs Aluminum: Which Is Better for Test Fixtures?

When it comes to choosing the ideal material for test fixtures, the debate often centers around FR4 epoxy board and aluminum. Both materials offer unique advantages, but FR4 epoxy board emerges as the superior choice for most test fixture applications. Its excellent electrical insulation properties, dimensional stability, and cost-effectiveness make it particularly well-suited for precision testing environments. While aluminum boasts high thermal conductivity and strength, FR4's combination of electrical performance, machinability, and thermal stability often proves more beneficial in test fixture scenarios. The decision ultimately depends on specific application requirements, but FR4 epoxy board generally provides a more versatile and reliable solution for test fixtures across various industries.
