Kudzivirirwa Kwekuchengetedza Panguva yeChiedza che LED -emitting Diode Packaging process

1. Mukugadzira, kuchengetedza, kutakura uye kusangana kweLeD kurongedza kuchengetedzeka, chiridzwa, midziyo, zvinhu, uye vashandisi vanogona kuburitsa nyore zviuru zvevoltage nekuda kwekupokana. Kana iyo LED ikasangana neaya machaji, muviri wakachajiswa unoburitsa kuburikidza ne LED 2. Nekuda kweiyo yepamusoro resistivity ye semiconductor zvinhu, iyo yekunzwa charge inogadzirwa nechip panguva yekugadzira maitiro haisi nyore kunyangarika. , Inogona kugadzira yakakwira electrostatic voltage. Voltage iyi inoburitsa simba rakasimba rekukuvara kwemagetsi rinongori mazana kuzviuru zvemukati wekusunga kana PIN mukati memukati kana PIN yemunda wakasimba wemagetsi kupaza nepakati pe LED. Practical effect. Sezvinoratidzwa mumufananidzo 2-2, kukanganisa kwe LED yemukati chip inokonzerwa ne static kana magetsi kusunungurwa. Kazhinji, iyo diki saizi yechishandiso, idiki iyo electrostatic voltage yaunokwanisa kumira, iyo yakakura iyo static magetsi ichiityisidzira. Kukuvara kweiyo LED yemukati chip yakakonzerwa neiyo static electrostatic kuburitswa. Munguva yekuita, zviitwa zvemushandisi zvakakura uye zvinowanzoitika, uye kune akawanda anobatika nezvinhu uye zvishandiso. Kana static dziviriro yekudzivirira ikaitwa zvinoenderana nekuchengetedzwa kwemagetsi panguva yekushanda, iyo yakaunganidzwa static magetsi haizoendeswe kunze nenguva, uye iyo LED ichakonzerawo LED Huge kukuvara. Tafura 2-1 inonyora yakajairika voltage pamuviri wemunhu. Sezvinoonekwa kubva Tafura 2-1, mukuita ine hunyoro hushoma hwehukama, zvakakosha zvakanyanya kuita inodiwa static dziviriro uye kunyatso kudzora kukuvadzwa kwemagetsi emuviri wemunhu kune mudziyo. Nekudaro, magetsi emunhu ari nyore kufuratirwa, uye akawanda akawandisa emagetsi ekudzivirira matanho zvakare ari nyore kufuratira. Munguva yese ye LED yekurongedza maitiro, vese vashandi vanoita mashandiro ekuita vanofanirwa kugara vachichengeta iyo pfungwa yekuchengetedzwa kwakamira mupfungwa.
