What is the lead frame type LED package structure
LED pin-type package with a lead frame for a variety of pin package outline, was the first successfully developed-market package, extensive number of varieties, high technical maturity, and the reflective layer inside the package structure continues to improve. Standard LED is considered to be most customers currently shows the industry's most convenient and most economical solution, housed in a typical conventional LED 0.1W input power can withstand the internal encapsulation, 90% of the heat is negative pin distributing frame to the PCB board, and then into the atmosphere, how to reduce the working temperature of the pn junction is packaged with the application must be considered. Encapsulating material to use more high temperature curing epoxy resin, its excellent optical performance, good process adaptability, the product can be * high, it can be made transparent colored or colorless transparent and colored or colorless scattering scattering lens package, different lens constitute a variety of shapes shape and size, for example, a circle divided by diameter Φ2mm, Φ3mm, Φ4.4mm, Φ5mm, Φ7mm and several kinds of different parts of the epoxy group can produce different lighting effects.
