Chidziwitso Chogwiritsa Ntchito Lamp Bead ya LED

Mikanda ya nyali ya LED ili ndi mwayi wapadera, koma mikanda ya nyali ya LED ndi chinthu chosatetezeka cha semiconductor, kotero tiyenera kusamala tikamagwiritsa ntchito mikanda ya nyali ya LED. Chonde phatikizani kufunikira kwakukulu kwa. (1) Magetsi ayenera kugwiritsidwa ntchito popereka magetsi a DC. Ena opanga opanga amagwiritsidwa ntchito pofuna kuchepetsa mtengo wa mankhwala kuti agwiritse ntchito njira ya "kukaniza voliyumu" yopangira magetsi a nyali za LED, zomwe zidzakhudza mwachindunji moyo wa zinthu za LED. Kugwiritsa ntchito magetsi apadera osinthira (makamaka nthawi zonse) magetsi kuzinthu za LED sikungakhudze moyo wautumiki wa chinthucho, koma mtengo wake ndi wokwera kwambiri. (2) Njira zina zotsutsana ndi ma static ziyenera kutsatiridwa pokonza ndi kupanga njira zotsutsana ndi static. Ngati ndi kotheka, mutha kukhazikitsa mafani a anti-static ion, ndipo nthawi yomweyo, ndikofunikira kuonetsetsa kuti chinyontho cha msonkhanowo chili pafupifupi 65%, kuti musakhale owuma kwambiri kuti mupange magetsi osasunthika, makamaka ma LED obiriwira ndi ofanana. zosavuta kuonongeka ndi static kuwonongeka magetsi. Kuphatikiza apo, maluso osiyanasiyana -grade LED anti -static amathanso amasiyana. Mphamvu za anti-static za LED zokhala ndi kalasi yapamwamba ziyenera kukhala zamphamvu. Pakhoza kukhala abwenzi ambiri omwe sadziwa bwino magetsi osasunthika. Ndidzawonetsa chidziwitso cha magetsi osasunthika mwatsatanetsatane apa: chinsinsi cha magetsi osasunthika ndi ndalama zowonjezera. Charge ndi kuchuluka kwamphamvu kwa magetsi osasunthika. Chingelezi chimatchedwa ESD. Ndalama zokhudzana ndi zomwe zingatheke, magetsi, zamakono, ndi zina zotero. ndi kuchuluka kwakuthupi komwe kumachitika chifukwa cha kukhalapo kwa mtengo kapena kusuntha kwa mtengowo. Mavuto ambiri a electrostatic amayamba chifukwa cha anthu opanda chidziwitso cha ESD. Ngakhale pano, anthu ambiri amakayikira kuti ESD idzawononga zinthu zamagetsi. Izi ndichifukwa chakuti kuwonongeka kwakukulu kwa ESD kumachitika pansi pa kumverera kwa munthu, chifukwa thupi la munthu limaganiziridwa kuti voteji ya static discharge ili pafupi ndi 3KV, ndipo zida zambiri zamagetsi zidzawonongeka zikakhala mazana a volts kapena ma volts ambiri. Kawirikawiri, pamene zipangizo zamagetsi zawonongeka ndi ESD Palibe malire odziwikiratu, ndipo chigawocho chimayikidwa pa PCB chisanazindikire. Zotsatira zake, pali mavuto ambiri, ndipo kusanthula kumakhala kovuta. Makamaka pakuwonongeka komwe kungachitike, ndizovuta kuyeza momwe amagwirira ntchito ngakhale ndi zida zolondola, kotero onse opanga zamagetsi ndi opanga amakayikira ESD. M'zaka zaposachedwa, kuyesera kwatsimikizira kuti izi zitha kuwonongeka kudzakhala Kudalirika kumachepa kwambiri. (3) Kutentha kwa LED kuyenera kulabadira kuwonjezeka kwa kutentha kumapangitsa kukana kwamkati kwa LED kukhala kochepa. Pambuyo pakutentha kwachilengedwe kwa dziko lakunja, kukana kwamkati kwa LED kudzachepetsedwa. Pambuyo popitilira momwe ntchito yake ikugwiritsidwira ntchito, idzakhudza moyo wautumiki wa zinthu za LED. Idzawotchedwa kwambiri ndi magetsi a LED. Choncho, ndi bwino kugwiritsa ntchito gwero lamakono kuti muwonetsetse kuti magetsi a LED sakukhudzidwa ndi kutentha kwakunja. Kutentha kwa LED ndichinthu chofunikira kwambiri chomwe chimakhudza moyo wa LED. Chonde kukopa chidwi. (4) Kusindikizidwa kwa zinthu za LED mosasamala kanthu za zomwe zida za LED zili, bola zikugwiritsidwa ntchito panja, zimayang'anizana ndi zisindikizo zosalowa madzi ndi chinyezi. Ngati sizikugwiridwa bwino, zidzakhudza mwachindunji moyo wautumiki wa zinthu za LED. Tsopano pali ochepa opanga omwe ali ndi zofunikira zamtundu wapamwamba kuti asindikize mikanda ya nyali ya LED yokhala ndi utomoni wachikhalidwe wa epoxy. Njira iyi ndiyosavuta kugwiritsa ntchito. Sikoyenera kwa zida za LED zokhala ndi voliyumu yayikulu. Idzawonjezera kulemera kwa mankhwala. (5) Pakali pano mikanda ya nyali ya LED sichitha kupitirira IF panopa ya IF yamakono ya LED idzapangitsa kuti mikanda ya nyali ya LED ikhale yochepa. Ngati ipitilira, imawotcha mikanda ya nyali ya LED nthawi yomweyo. (6) LED yopinda ngodya ayenera kulabadira mikanda LED nyali pamene ngodya kapena lopinda ngodya, chonde musakhale pafupi kwambiri ndi colloid. Sungani mtunda wopitilira 2mm kuchokera ku colloid. Chiwerengero cha makutu sichikhoza kupitirira katatu, ngodya imapindika mpaka 90, ndiyeno malo oyambirira ndi kamodzi. (7) The kuwotcherera kutentha kutentha kuwotcherera ndi za 260 C, nthawi zimalamulidwa mkati 5S, ndi kuwotcherera mfundo pamwamba 2.5mm kuchokera pansi pa colloid. 310S chitsulo chosapanga dzimbiri chitoliro munthu pitilizani template 304 chitsulo chosapanga dzimbiri chitoliro malemba Tibetan
