Design & Materials
This spacer is manufactured from high-purity oxygen-free copper TU1 (C1020) or T2 (C1100) to ensure excellent electrical conductivity and thermal performance.
Controlled dimples or bosses (round or square) improve positioning accuracy during soldering or laser welding.
Pickling and passivation enhance surface cleanliness and welding consistency, supporting stable long-term performance.
