Number of component pairs: 127 Assembly pressure: 85N/cm2 Be sure to apply thermal grease when installing the radiator The literal is cold side, and the non-literal is hot side Packaging process: standard 704 silicone rubber seal around Packaging standard: foam box packaging, storage conditions ambient temperature -10 ~ 40 degrees Celsius Working environment: temperature range -5583 degrees Celsius (excessive ambient temperature will directly affect the cooling efficiency) The working state of the cooling plate is that one side is cooling and the other side is heating, and the heating surface must be well dissipated during work. It is strictly forbidden to energize for more than 2 seconds without heat dissipation, so as to avoid overheating and burning. C$12.01 C$14.04

Made of high-strength materials, after heat treatment and hardening, the tweezers have high elasticity, bendable, and not easily deformed. The fine tip of industrial tweezers, with non-magnetic coating and high hardness, can be used for precise operations, such as circuit board welding or watch repair. The ESD (Surface Electrostatic Discharge) design protects components and handles from the damaging effects of static electricity. Exquisite appearance and ergonomic design, long-term use of fingers will not fatigue, convenient and safe. Fit for PC, semiconductor, watch fixing, electronics maintenance, jewelry, precision electronic components, laboratory work, stamp and more works.
