Chitetezo cha Chitetezo Pa Nthawi Yopangira Kuwala kwa LED -emitting Diode Packaging process

1. Popanga, kusungirako, kuyendetsa ndi kusonkhanitsa chitetezo cha ma LeD ma CD, zida, zida, zida, ndi ogwiritsa ntchito amatha kupanga mosavuta masauzande amagetsi chifukwa cha mikangano. Kuwala kwa LED kukalumikizana ndi zolipiritsa izi, thupi loyimbidwa limatuluka kudzera pa LED 2. Chifukwa cha kukana kwakukulu kwa zida za semiconductor, zomverera zomwe zimapangidwa ndi chip panthawi yopanga sizovuta kutha. , Ikhoza kupanga magetsi apamwamba a electrostatic. Voltage iyi ipanga mphamvu yamagetsi yowonongeka yamagetsi yomwe imangokhala mazana mpaka masauzande a kutchinjiriza kwamkati kapena PIN muzotsekera zamkati kapena PIN ya malo amphamvu amagetsi kuti athyole LED. Zothandiza. Monga momwe tawonetsera pa Chithunzi 2-2, kuwonongeka kwa chipangizo chamkati cha LED chifukwa cha static kapena kumasulidwa kwamagetsi. Nthawi zambiri, kukula kwa chipangizochi kukakhala kochepa, mphamvu yamagetsi ya electrostatic yomwe mungathe kupirira imakhala yocheperapo, mphamvu yamagetsi yoyima imakulirakulira. Kuwonongeka kwa chipangizo chamkati cha LED chifukwa cha kutulutsidwa kwa static electrostatic. Panthawiyi, ntchito za wogwiritsa ntchito zimakhala zazikulu komanso zomwe zimachitika kawirikawiri, ndipo pali zambiri zokhudzana ndi zipangizo ndi zipangizo. Ngati chitetezo cha static chikuchitika molingana ndi chitetezo cha electrostatic panthawi ya opaleshoni, magetsi osasunthika omwe amasonkhanitsidwa satumizidwa kunja panthawi yake, ndipo LED idzachititsanso kuwonongeka kwakukulu kwa LED. Table 2-1 imatchula mphamvu yamagetsi pa thupi la munthu. Monga tikuwonera mu Table 2-1, munjira yokhala ndi chinyezi chochepa kwambiri, ndikofunikira kwambiri kuti muteteze chitetezo chokhazikika ndikuwongolera kuwonongeka kwa voteji yamunthu pa chipangizocho. Komabe, magetsi osasunthika amunthu ndi osavuta kunyalanyazidwa, ndipo njira zambiri zotetezera ma electrostatic ndizosavuta kunyalanyaza. Pa nthawi yonse yoyika ma LED, ogwira ntchito onse omwe amagwira ntchito ayenera kukumbukira nthawi zonse lingaliro la chitetezo chokhazikika.
