1. Anti-static

Fakitale yopanga zowonetsera iyenera kukhala ndi miyeso yabwino yotsutsa-static.Malo odzipatulira odana ndi malo amodzi, pansi, anti-static soldering iron, anti-static table mat, anti-static ring, anti-static dress, anti-static control, chinyezi, kuyika zida (makamaka chodula phazi), ndi zina zonse ndi zofunika. zofunika, ndipo ziyenera kufufuzidwa nthawi zonse ndi static mita.

2. Kuyendetsa dera kamangidwe

Makonzedwe a woyendetsa IC pa bolodi loyendetsa galimoto pa gawo lowonetsera lidzakhudzanso kuwala kwa LED.Popeza kutulutsa kwaposachedwa kwa dalaivala IC kumaperekedwa mtunda wautali pa bolodi la PCB, kutsika kwamagetsi kwa njira yotumizira kudzakhala kwakukulu, zomwe zidzakhudza mphamvu yamagetsi yamagetsi ya LED ndikupangitsa kuwala kwake kuchepa.Nthawi zambiri timapeza kuti kuwala kwa ma LED ozungulira gawo lowonetsera kumakhala kochepa kusiyana ndi pakati, chifukwa chake.Chifukwa chake, kuti muwonetsetse kugwirizana kwa chiwonetsero chazithunzi chowala, ndikofunikira kupanga chojambula chogawa dalaivala.

3. Pangani mtengo wamakono

Mphamvu yamagetsi ya LED ndi 20mA.Nthawi zambiri, tikulimbikitsidwa kuti ntchito yayikulu yomwe ikugwira ntchito isapitirire 80% ya mtengo womwewo.Makamaka paziwonetsero zokhala ndi kadontho kakang'ono, mtengo wapano uyenera kutsitsidwa chifukwa chakuwonongeka kwa kutentha.Malinga ndi zomwe zinachitikira, chifukwa cha kusagwirizana kwa liwiro la kuchepa kwa ma LED ofiira, obiriwira, ndi a buluu, mtengo wamakono wa ma LED a buluu ndi obiriwira uyenera kuchepetsedwa m'njira yolunjika kuti zisagwirizane ndi zoyera zowonetsera. mutatha kugwiritsa ntchito nthawi yayitali.

4. Magetsi osakanikirana

Ma LED amtundu womwewo komanso milingo yowala yosiyana ayenera kusakanizidwa, kapena kuyikidwa molingana ndi chithunzi choyikapo chopangidwa motsatira malamulo apadera kuti zitsimikizire kugwirizana kwa kuwala kwa mtundu uliwonse pazenera lonse.Ngati pali vuto mu ndondomekoyi, kuwala kwa m'deralo kudzakhala kosagwirizana, zomwe zidzakhudza mwachindunji mawonekedwe a chiwonetsero cha LED.

5. Yang'anirani kuima kwa nyali

Pakuti mu mzere LEDs, payenera kukhala zokwanira ndondomeko luso kuonetsetsa kuti LED ndi perpendicular bolodi PCB podutsa ng'anjo.Kupatuka kulikonse kudzakhudza kukhazikika kwa kuwala kwa LED komwe kwakhazikitsidwa, ndipo midadada yamitundu yokhala ndi kuwala kosagwirizana idzawonekera.

6. Wave soldering kutentha ndi nthawi

Kutentha ndi nthawi yowotcherera kutsogolo kuyenera kuyendetsedwa mosamalitsa.Ndibwino kuti kutentha kwa preheating ndi 100 ℃ ± 5 ℃, ndipo kutentha kwapamwamba kuyenera kusapitirira 120 ℃, ndi kutentha kwa preheating kuyenera kuwuka bwino.Kutentha kwa kuwotcherera ndi 245 ℃ ± 5 ℃.Ndibwino kuti nthawiyo isapitirire masekondi atatu, ndipo musagwedeze kapena kugwedeza LED pambuyo pa ng'anjo mpaka ibwerere kutentha.Magawo a kutentha kwa makina osokera amayenera kuyang'aniridwa pafupipafupi, zomwe zimatsimikiziridwa ndi mawonekedwe a LED.Kutentha kwakukulu kapena kusinthasintha kungawononge mwachindunji LED kapena kuyambitsa mavuto obisika, makamaka ma LED ozungulira ndi oval monga 3mm.

7. kuwotcherera kulamulira

Pamene chiwonetsero cha LED sichiyatsa, nthawi zambiri pamakhala mwayi woposa 50% kuti umayamba chifukwa cha mitundu yosiyanasiyana ya soldering, monga LED pin soldering, IC pin soldering, pin header soldering, ndi zina zotero. kuwongolera mosamalitsa kwa njirayo ndikulimbitsa kuwunikira koyenera kuti athetse.Kuyesa kwa vibration musanachoke ku fakitale ndi njira yabwino yoyendera.

8. Mapangidwe a kutentha kwa kutentha

LED idzatulutsa kutentha pamene ikugwira ntchito, kutentha kwakukulu kumakhudza kuthamanga kwapamwamba ndi kukhazikika kwa LED, kotero kuti mapangidwe a kutentha kwa PCB board ndi mpweya wabwino ndi kutentha kwa nduna zidzakhudza ntchito ya LED.
