Packing:
Tantalum boards are wrapped with pearl cotton and then packed into wooden cases. Our reasonable packing method can avoid collision and damage of tantalum boards during transportation and prevent the impact of external goods on products, so as to ensure the integrity of products in the delivery process after leaving the factory.
