Chifukwa chiyani UVLED Chip Packaging Welding Imagwiritsa Ntchito Vuto Lobwezeretsa Ng'anjo?

Kutuluka kwa UVLED ndikusintha kosintha kwamakampani a UV. Kuwala kwake kumakhala kosalekeza, ndikuwongolera kwambiri kutentha, kusamala zachilengedwe komanso kunyamula. Choyamba, moyo wautumiki wa ultraviolet kuchiritsa dongosolo ndi wautali kuposa chikhalidwe UV solidification maola 800-3000, mpaka maola 20,000-30000, nyali ya mercury imayamba pang'onopang'ono, yomwe imakhudza mwachindunji moyo wa babu. Bright, osati kutayika kochepa chabe, komanso kupulumutsa mphamvu zambiri. Kachiwiri, nyali yachikhalidwe ya mercury imawala, ndipo ndani ali ndi siliva mu babu, kugwiritsa ntchito molakwika kumayambitsa kuipitsidwa kwakukulu kwa chilengedwe, komanso kukhudza moyo ndi thanzi la anthu. Mikanda ya nyali ya LED imagwiritsa ntchito kuyatsa kwa semiconductor, komwe kulibe zinthu zovulaza, ndipo sikungawononge chilengedwe. Kuphatikiza apo, njira yachikhalidwe ya nyali ya mercury ikagwiritsidwa ntchito ndi cheza cha ultraviolet, kutentha kwapamwamba kwa chinthucho kumakhala kokwera mpaka 60-90 C, zomwe zingayambitse kusamuka kwazinthu ndikusintha. LED ikagwiritsidwa ntchito, palibe kuwala kwa infrared. Zotsatirazi, sizingawonekere kwa mankhwala, zomwe zimapangitsa kuti ntchitoyo ikhale yokhazikika. Mwachidule, UVLED ndi chitukuko chamtsogolo, koma palinso zolakwika pa UVLED. Kuchuluka kwa mphamvu yamagetsi sikukwanira, zomwe zimakhudza ma inki a UV kuti athetse kuthamanga. Chifukwa chake kudalirika kwamagulu ndikosauka, zomwe zimapangitsa UVLED kubweretsa zovuta zambiri pakukweza. Njira yowotchera ng'anjo ya vacuum ya UVLED chip phukusi yowotcherera ndi kuwotcherera idawonekera panthawiyo. Itha kuchepetsa kuchuluka kwa chip champhamvu kwambiri cha UVLED mpaka 3%. Pa nthawi yomweyo, ngati mapangidwe Kutentha gawo lapansi ndi madzi ozizira pa kapangidwe, akhoza kupanga kutentha dissipation kuzirala ndi kothandiza kwambiri, potero Iwo kwambiri bwino kudalirika kwa mkulu -mphamvu UVLED, ndipo akhoza kutsegula msewu kwa UVLED m'madera ambiri. mtsogolomu.
