> Use Mainly used for a variety of optical devices required for fiber optic local welding or fiber package airtight seal structure requirements. > Features This product uses sophisticated chemical plating process preceding the desired fiber length, fiber cladding outside and then gold-plated nickel plated nickel layer on the surface; so as to achieve the purpose of the fiber partial metallization. Good weldability, can withstand 280 ℃ welding solder 30 seconds, good adhesion, high tensile strength (hot solder process Rally Secretary Chu Xinggong reach 10N). The total thickness of the coating: 3-4um, gold layer thickness ≮0.1um.
