Ukukhetha i-SMD LED PCB efanele yephrojekthi yakho kuyisinyathelo esibalulekile ekuklameni uhlelo oluphumelelayo olusekelwe ku-LED.Kunezici ezimbalwa okufanele uzicabangele lapho ukhetha i-SMD LED PCB.Lezi zici zihlanganisa ubukhulu, ukuma nombala wama-LED kanye namandla kagesi kanye nezidingo zamanje zephrojekthi.Ngaphezu kwalokho, kufanele ucabangele ukuklama okuphelele kwesistimu.Kulesi sigaba sizobheka ukucatshangelwa okubalulekile kokukhetha i-SMD LED PCB efanele.
1. Ukucaciswa kwe-LED
Into yokuqala okufanele uyicabangele lapho ukhetha ibhodi lesifunda eliphrintiwe le-SMD LED ukucaciswa kwe-LED.Kubalulekile ukucabangela umbala wama-LED njengoba lokhu kuzothinta ukubukeka okuphelele kwephrojekthi.Ama-LED ama-SMD anemibala eyahlukene okuhlanganisa obomvu, oluhlaza okotshani, oluhlaza okwesibhakabhaka, ophuzi, omhlophe kanye nama-RGB ashintsha umbala.
Okunye ukucaciswa okufanele kucatshangelwe kufaka phakathi usayizi nokuma kwama-LED.Kungaba nomthelela ekuklanyweni okuphelele kwesistimu.Ama-LED ama-SMD eza ngosayizi abaningana.Lawa masayizi angu-0805, 1206 kanye no-3528 futhi umumo ungaba yindilinga, unxande noma isikwele.
2. Amazinga okukhanya kwama-LED
Izinga lokukhanya kwe-LED nalo liyinto ebalulekile okufanele icatshangelwe.Izinga lokukhanya lizothinta inani lokukhanya elikhishwa i-LED.Singakwazi ukukala amazinga okukhanya ngokuya ngama-lumens.Ingasukela kukukhanya okumbalwa kwama-LED wamandla aphansi iye kumakhulu amaningana ama-lumens wamandla aphezulu e-LED.
3. Izidingo zamandla kagesi kanye nezamanje
Ukucatshangelwa kwesithathu lapho ukhetha amabhodi wesekethe ephrintiwe ye-SMD LED amandla kagesi kanye nezidingo zamanje zephrojekthi.Ama-LED ama-SMD ngokuvamile adinga i-voltage ephansi kanye namanje aphansi ukuze asebenze.Lezi zidingo zamandla kagesi aphansi zisuka ku-1.8V ziye ku-3.3V futhi izidingo zamanje zisukela ku-10mA kuya ku-30mA.
Kubalulekile ukuqinisekisa ukuthi amandla kagesi kanye nezidingo zamanje zephrojekthi ziyahambisana ne-PCB.Ukukhetha i-PCB enevoltheji ephansi kakhulu noma ephezulu kakhulu kungalimaza ama-LED noma i-PCB.
4. Usayizi we-PCB nesimo
Usayizi nokuma kwe-PCB nakho kuwukucatshangelwa okubalulekile lapho ukhetha i-SMD LED PCB.usayizi we-PCB uzoncika enanini lama-LED adingekayo kuphrojekthi.Kuphinde kuncike esikhaleni esitholakalayo ku-PCB.
Kubalulekile ukucabangela usayizi nokuma kwe-PCB ngokuphathelene nomklamo jikelele.Isibonelo, uma isistimu iphatheka noma igqokeka, i-PCB encane nehlangene ingase ifaneleke kakhulu.
5. Izici zokuklama
Kubalulekile ukucabangela izici zokuklama zamabhodi wesifunda aphrintiwe we-SMD LED.i-PCB ingase ihlanganise izici ezifana nezimbangi ezihlanganisiwe, ezingenza inqubo yokuklama ibe lula futhi inciphise inani lezingxenye.
6. Ukucatshangelwa kokushisa
Okunye okucatshangelwayo okubalulekile lapho ukhetha ama-PCB e-SMD LED ukuphathwa okushisayo kwama-LEDs.Ama-LED ama-SMD angakwazi ukukhiqiza ukushisa okukhulu, ikakhulukazi ama-LED wamandla aphezulu.Ngakho-ke, ukuphathwa okushisayo okufanelekile kubalulekile ukuvimbela ukulimala kwama-LED nokuqinisekisa ukusebenza kahle.
Lapho ukhetha i-SMD LED PCB, kubalulekile ukucabangela ukuhanjiswa okushisayo kwezinto ze-PCB.Izici ezengeziwe zokuphatha okushisayo, njenge-thermal vias, okungase kudingeke ukuze kukhishwe ukushisa okuvela kuma-LED, kufanele kucatshangelwe.
7. Izidingo zokukhiqiza
Izidingo zokukhiqiza zama-SMD LED PCB nazo zidinga ukucatshangelwa.Lokhu kufaka phakathi izici ezifana nobubanzi bokulandelela obuncane kanye nephimbo elidingekayo ku-PCB.Ungangeza izinqubo ezithile zokukhiqiza, ezifana nokwelashwa kwendawo noma ukucwenga, ongase ukudinge.
Kubalulekile ukukhetha amabhodi esekethe ephrintiwe e-SMD LED ongawenza usebenzisa inqubo oyithandayo yokukhiqiza kanye nemishini.Lokhu kungasiza ukuqinisekisa ukuthi ukhiqiza i-PCB ngokunembile nangempumelelo, wehlise ubungozi bamaphutha noma amaphutha.
8. Izidingo zemvelo
Izidingo zemvelo zama-SMD LED PCBs kumele zibhekwe lapho kukhethwa i-PCB efanele.Lokhu kuhlanganisa izici ezifana nebanga lokushisa, ukumelana nomswakama, nokuchayeka kumakhemikhali noma ezinye izici zemvelo.
Uma usebenzisa isistimu esekelwe ku-LED endaweni enzima, khetha i-SMD LED PCB engakwazi ukumelana namazinga okushisa adlulele.
9. Ukuhambisana nezinye izingxenye
Ukuhambisana kwe-SMD LED PCB nezinye izingxenye ohlelweni nakho kubalulekile ukucatshangelwa.Lokhu kuhlanganisa nokuqinisekisa ukuthi i-PCB iyahambisana nesekhethi yomshayeli kanye nokuphakelwa kwamandla.
Kubalulekile ukucabangela izilinganiso ze-voltage kanye nezamanje zesekethe yomshayeli kanye nokunikezwa kwamandla.Kubalulekile ukuqinisekisa ukuthi ahambisana ne-voltage kanye nezidingo zamanje zama-LED kanye ne-PCB.
10. Ukucatshangelwa kwezindleko
Okokugcina, lapho ukhetha i-PCB efanele, izindleko ze-SMD LED PCB kufanele zicatshangelwe.izindleko ze-PCB zizoncika ezintweni ezimbalwa ezifana nosayizi, ubunzima kanye nezidingo zokukhiqiza ze-PCB.
Kubalulekile ukulinganisa izindleko ze-PCB nezidingo zephrojekthi.Ngaphezu kwalokho, qinisekisa ukuthi i-PCB ekhethiwe ihlinzeka ngokusebenza okudingekayo kanye nokusebenza ngenkathi uhlala ngaphakathi kwesabelomali.
