4.Why should choose Uniwell as your supplier?


5.Little knowledge --- Basic knowledge of LED aluminum substrate.
The heat dissipation of LED is the biggest headache for LED manufacturers.Heat dissipation LED aluminum plate is a kind of supply heat conduction of preface, LED to heat dissipation base board, cooling module, it can add LED area at the bottom, add heat dissipation area, mainly composed of copper foil circuit/ceramic powder + polymer/aluminum plate.Heat dissipation substrate has high thermal conductivity, safety, environmental protection and other functions in the application of LED industry.The following is chengzhiyi circuit co., LTD. To introduce the LED aluminum substrate with aluminum information. Due to the high thermal conductivity and heat dissipation of aluminum, it can be used to export the internal heat.LED aluminum substrate is a common metal coated copper plate with excellent thermal conductivity, electrical insulation and mechanical processing.When designing, try to get the PCB close to the aluminum base, and then reduce the thermal resistance of the filling adhesive. 

Circuit layer (that is, the copper foil) usually by etching printed circuit, the component parts of the mutual connection, usually, greatly current-carrying circuit layer needs talents, then we should use thicker copper foil, thickness is usually 35 microns to 280 microns;Thermal insulation is the location of LED aluminum plate core skills, it is usually made up of special ceramics fill special polymer, small heat resistance, excellent viscoelastic functions, with thermal aging, can accept mechanical and thermal stress.

The thermal insulation layer of the high-functioning LED aluminum substrate is used to make it have excellent thermal conductivity and high strength electrical insulation.Metal layer is LED aluminum plate support components, demand with high thermal conductivity, is usually aluminum plate, also can use copper (copper can supply very good thermal conductivity), appropriate in drilling, punching and shearing and cutting practices such as mechanical processing.The PCB data has the advantage of not being comparable with other data.Suitable power elements for SMT.Without radiator, the volume is greatly reduced, the cooling effect is excellent, excellent insulation function and mechanical function.
