With the development of science and technology, customers have higher and higher requirements for electronic products. All electronic products require more and more miniaturization and miniaturization on the basis of functional strengthening. EMAR Hardware has been pursuing technological progress and striving to meet customer requirements. After unremitting efforts, it has finally overcome the technical difficulties and manufactured a miniature beryllium copper shielding reed with a thickness of only 0.05mm. It fills the technical gap of ultra-thin beryllium copper shielding reeds.
