[UVLED] Ibhodi yeSekethe yePCB UVLED uMthombo wokuKhanya woShicilelo

Ibhodi yesekethe yePCB Umthombo wokukhanya wokushicilela we-UVLED yitshiphu ye-LED njengomatshini wokunyanga we-PCB onetshiphu ye-LED. Yahlukile koomatshini bokunyanga be-PCB abafana nezibane zemercury kunye nezibane zehalogen. Inamandla ngokwentelekiso, ngoko ke amandla okukhanya ewonke emithombo yokukhanya eprintiweyo ye-UVLED mancinci ngokwentelekiso (xa kuthelekiswa nokukhanya okupheleleyo kwesibane semercury) ukuqinisa ngokupheleleyo. Ibhodi yesekethe yePCB ye-UVLED umgaqo womthombo wokukhanya wokushicilela: ukongeza unobangela wokukhanya (okanye i-photoresist) kwintlaka yefomyula ekhethekileyo, emva kokufunxa ukukhanya okuphezulu kwe-ultraviolet kwi-ultraviolet (UV) izixhobo zokunyanga, iiradicals zasimahla okanye isiseko se-ion ziyasebenza. eveliswayo, ngaloo ndlela Unyango lokudityaniswa, ukudityaniswa komnqamlezo, kunye neempendulo ze-branching, i-resin (iingubo ze-UV, i-inks, i-adhesives, njl.) iguqulwe ukusuka kulwelo ukuya kwimeko eqinileyo phakathi kwemizuzwana embalwa (akukho). PCB optical ephilisa UVLED umatshini woshicilelo ukukhanya umthombo umatshini PCB inki iimpawu: (1) viscosity: ebizwa ngokuba yi-viscosity yi-friction yangaphakathi yolwelo, ebonisa ukuba phantsi kwesenzo samandla angaphandle, umaleko omnye wezilayidi zolwelo kwelinye umaleko wolwelo, kwaye ulwelo lwangaphakathi lusetyenziswa kulwelo lwangaphakathi. Ukukhuhlana kwe-inki eprintiweyo ye-PCB ayizukrwelwa zizinto zangaphandle. (2) Ubuchule: I-Tentile yimpawu ezibonakalayo zolwelo, oko kukuthi, i-viscosity yayo iyancipha kwisimo esishukumisayo, kwaye emva kwe-static, iya kubuyisela ngokukhawuleza iimpawu zayo zokuqala ze-viscosity. Ngokushukumisa, umphumo we-tactile degeneration uqhubeka ixesha elide, elaneleyo ukwenza isakhiwo sayo sangaphakathi sidibanise. Ukufezekisa iziphumo zoshicilelo oluphezulu, i-tactileness ye-inki ibaluleke kakhulu. (3) Ukulunga: Izigcwalisi zebala kunye neeminerali zidla ngokuqinileyo. Emva kokugaya okulungileyo, ubungakanani bayo be-particle ayidluli i-4/5 microns, kwaye ifom eqinile yokwenza i-homogeneous liquidity state. Ngoko ke, kubaluleke kakhulu ukufuna i-inki ukuze ibe nokucoleka. Ulwazi oluninzi lwamkelekile ukuba ungene
