Method for manufacturing light emitting diode package having LED die fixed by anisotropic conductive paste

A method for manufacturing LED packages, comprising steps:

• providing a substrate and forming a plurality of pairs of electrodes on the substrate;
• forming a plurality of reflective cups on the substrate, each reflective cup surrounding a corresponding pair of the electrodes;
• positioning anisotropic conductive pastes on the substrate and attaching each anisotropic conductive paste to a corresponding pair of the electrodes;
• positioning an LED die on the each anisotropic conductive paste and electrically connecting the LED die to the corresponding pair of the electrodes with the each anisotropic conductive paste by compressing;
• forming an encapsulation on the substrate to cover the LED dies;
• and
• cutting the substrate to obtain individual LED packages each including a corresponding LED die;
• wherein the compressing process is operated by steps:
• arranging a buffer layer on the reflective cups;
• pressing the buffer layer with a mold and under a predetermined temperature into the reflective cuts to press the anisotropic conductive pastes to deform and electrically interconnect the LED dies and the electrodes;
• and
• removing the mold and the buffer layer.
