[Kuwonekera kwa PCB] Kugwiritsa ntchito UV LED Technology mu PCB Exposure

Kubwera kwa ma LED a UV, ukadaulo wa UVLED unayamba kugwira ntchito pang'onopang'ono m'mafakitale osiyanasiyana, ukadaulo wakuchiritsa wa UV wabweretsa kusintha kwa PCB, chifukwa pali zabwino zambiri monga kugwiritsa ntchito mphamvu zochepa, magwiridwe antchito apamwamba, kuteteza chilengedwe, ndi zina zambiri. Ma LED a UV, UV LED Technology imagwiritsidwa ntchito kumunda wa PCB. Mu mawonekedwe a PCB, mawonekedwe a gwero la kuwala kwa nyali yakuwonetseredwa zimakhudza mwachindunji mtundu wa kuwonetseredwa ndi zotsatira za kukhudzana. Kugwiritsa ntchito kwa UV LED mu PCB kukhudzana makamaka ndi kugwiritsa ntchito ultraviolet Kuwala kwa Ultraviolet kumakhudzidwa ndi sensa -sensitive youma filimu kupanga zomwe zimachitika. Kugwiritsa ntchito mphamvu kwa nyali zachikhalidwe pakuwonekera kwa PCB ndikokwera kwambiri, ndipo moyo wautumiki ndi waufupi kwambiri, maola 800 okha, ndipo chubu la nyali liyenera kutenthedwa musanagwiritse ntchito. Nthawi yeniyeni yogwira ntchito ya chubu chowonekera cha PCB ndi yochepera 800 Maola. Nyali yachikhalidwe ya mercury idzatulutsa kutentha kwakukulu ndi kuwala kwa infrared pakugwiritsa ntchito kuwala, ndipo ndizosavuta kuwononga zokutira, kotero pali mtunda wina pakugwiritsa ntchito, kuti muchepetse mphamvu ya ntchito yake. . Kugwiritsa ntchito kwa UV LED pakuwonekera kwa PCB, poyerekeza ndi nyali zachikhalidwe za mercury, kuli ndi ubwino wa luminescence, moyo wautali, komanso kugwiritsa ntchito mphamvu zochepa, zomwe zimakhudzidwa kwambiri ndi opanga makina owonetsera kunyumba ndi akunja ndikuwapangitsa kuti azikulitsa ndi kuwakulitsa. Kutengera mwayi paukadaulo watsopano wa UV LED. Ngakhale mphamvu ya kuwala kwa LED imodzi ya UV sipamwamba, muzogwiritsira ntchito, magwero ake owunikira amatha kukwaniritsa kuwala kwa ultraviolet kwambiri kupyolera mu chithandizo chapadera cha kuwala ndi kuphatikiza kwapangidwe. Itha kugwiritsidwa ntchito pakuwonekera kwa PCB. Kugwiritsa ntchito njira zowunikira zowunikira kumatha kuchepetsa kukula kwa gwero la kuwala kwa UV, ndikuthetsa vuto la kutentha kwa UV LED. Kugwiritsa ntchito kwa UV LED mu PCB kukhudzana kuli ndi ubwino wambiri monga kugawa yunifolomu, kukhazikika, ndi kuchepa kwa ndalama za zipangizo, ndipo machitidwe a machitidwe osiyanasiyana ndi apamwamba kuposa momwe amachitira mwambo wamakono, kotero amatha kukumana ndi ndondomeko ya PCB.
