Momwe mungadziwire mtundu wa mizere ya kuwala kwa LED?

Ndi chitukuko cha sayansi ndi zamakono, magetsi a LED amatha kuwoneka kulikonse. Lero ndikuwuzani momwe mungadziwire mtundu wa mizere ya kuwala kwa LED. Msika wa kuwala kwa LED ndi wosakanikirana, ndipo mitengo yazinthu kuchokera kwa opanga nthawi zonse ndi zinthu zochokera kwa opanga copycat zimasiyana kwambiri.

Titha kupanga chizindikiritso choyambirira potengera mawonekedwe osavuta, ndipo titha kudziwa ngati mtunduwo ndi wabwino kapena woipa.

Itha kuzindikirika makamaka kuchokera kuzinthu izi:

1. Yang'anani pazitsulo zogulitsira. Mizere yowunikira ya LED yopangidwa ndi opanga mizere yowunikira pafupipafupi ya LED amapangidwa pogwiritsa ntchito ukadaulo wa SMT patch, pogwiritsa ntchito solder phala ndi reflow soldering. Chifukwa chake, zolumikizira zogulitsira pamtundu wa nyali ya LED ndizosalala komanso kuchuluka kwa solder sikwambiri. Zolumikizira zogulitsira zimayambira pa FPC pad kupita ku ma elekitirodi a LED mu mawonekedwe a arc.

2. Yang'anani khalidwe la FPC. FPC imagawidwa m'mitundu iwiri: yokhala ndi mkuwa komanso mkuwa wokulungidwa. Chojambula chamkuwa cha bolodi lovala zamkuwa chikuwonekera. Mukayang'anitsitsa, mutha kuziwona kuchokera pakugwirizana pakati pa pad ndi FPC. Mkuwa wokulungidwa umaphatikizidwa kwambiri ndi FPC ndipo ukhoza kupindika mwakufuna popanda pedi kugwa. Ngati bolodi lamkuwa lapindika kwambiri, mapadi amagwa. Kutentha kwambiri panthawi yokonza kumapangitsanso kuti mapepalawo agwe.

3. Yang'anani ukhondo wa pamwamba pa mzere wa LED. Pamwamba pa mizere yowunikira ya LED yopangidwa pogwiritsa ntchito ukadaulo wa SMT ndiukhondo kwambiri, wopanda zonyansa kapena madontho owoneka. Ziribe kanthu kuti pamwamba pa chowunikira chabodza cha LED chomwe chimapangidwa ndi kuwotcherera pamanja chimatsukidwa bwanji, madontho ndi madontho oyeretsera amakhalabe.

4. Yang'anani pa paketi. Zingwe zowunikira pafupipafupi za LED zimayikidwa mu anti-static reel, m'mipukutu ya 5 metres kapena 10 metres, ndipo zimasindikizidwa m'matumba opangira anti-static ndi chinyezi. Mtundu wa copycat wa mzere wowunikira wa LED umagwiritsa ntchito reel yobwezerezedwanso yopanda anti-static komanso matumba otsimikizira chinyezi. Ngati muyang'anitsitsa pa reel, mukhoza kuona kuti pali zotsalira ndi zowonongeka pamwamba zomwe zatsala pamene zolembazo zinachotsedwa.

5. Yang'anani pa zolembera. Matumba okhala ndi mizere yopepuka ya LED nthawi zonse amakhala ndi zilembo zosindikizidwa, osati zilembo zosindikizidwa.

6. Yang'anani pazowonjezera. Zopangira zowunikira pafupipafupi za LED zidzabwera ndi malangizo ogwiritsira ntchito komanso zowunikira m'bokosi loyikamo, komanso zimakhala ndi zolumikizira zowunikira za LED kapena zopalira makhadi; pomwe mtundu wa copycat wa mzere wowunikira wa LED ulibe zowonjezera izi mubokosi loyika, chifukwa Pambuyo pake, opanga ena amatha kusungabe ndalama.

Zindikirani pazowunikira zowunikira

1. Kuwala kofunikira kwa ma LED kumasiyanasiyana kutengera zochitika ndi zinthu zosiyanasiyana. Mwachitsanzo, ngati nyali zowonetsera zodzikongoletsera za LED zayikidwa m'malo akuluakulu ogulitsa, tiyenera kukhala ndi kuwala kwakukulu kuti tiwoneke bwino. Pantchito yokongoletsera yomweyi, pali zinthu zosiyanasiyana monga zowunikira za LED ndi mizere yowala yamtundu wa LED.

2. Anti-static mphamvu: Anti-static mphamvu Ma LED okhala ndi mphamvu zotsutsa-static amakhala ndi moyo wautali, koma mtengo udzakhala wapamwamba. Nthawi zambiri antistatic ndi yabwino kuposa 700V.

3. Ma LED okhala ndi utali wofanana ndi kutentha kwa mtundu adzakhala ndi mtundu womwewo. Izi ndizofunikira makamaka kwa nyali zomwe zimaphatikizidwa mochuluka. Osatulutsa mitundu yambiri yamitundu mu nyali imodzi.

4. Kutayikira panopa ndi panopa pamene LED imayendetsa magetsi mozungulira. Timalimbikitsa kugwiritsa ntchito zida za LED zokhala ndi kutayikira kochepa.

5. Kutha kwa madzi, zofunikira za magetsi akunja ndi mkati mwa LED ndizosiyana.

6. Kuwala kwa kuwala kwa LED kumakhudza kwambiri nyali za LED ndipo kumakhala ndi zofunikira zazikulu za nyali zosiyanasiyana. Mwachitsanzo, timalimbikitsa kugwiritsa ntchito madigiri 140-170 pa nyali za fulorosenti za LED. Sitidzafotokozera ena mwatsatanetsatane apa.

7. Tchipisi za LED zimatsimikizira mtundu wapakatikati wa ma LED. Pali mitundu yambiri ya tchipisi ta LED, kuphatikiza zochokera kumitundu yakunja ndi zaku Taiwan. Mitengo yamitundu yosiyanasiyana imasiyana kwambiri.

8. Kukula kwa chipangizo cha LED kumatsimikiziranso ubwino ndi kuwala kwa LED. Posankha, timayesetsa kusankha tchipisi tokulirapo, koma mtengo wake udzakhala wokwera.
