Ukukhetha i-PCB efanelekileyo ye-SMD ye-LED yeprojekthi yakho linyathelo elibalulekileyo ekuyileni inkqubo enempumelelo esekwe kwi-LED.Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha i-SMD LED PCB.Ezi zinto ziquka ubungakanani, imilo kunye nombala wee-LEDs kunye nombane kunye neemfuno zangoku zeprojekthi.Ukongeza, kufuneka uqwalasele uyilo lonke lwenkqubo.Kweli candelo siza kujonga imiba ephambili yokukhetha i-PCB efanelekileyo ye-SMD LED.
1. Iimpawu ze-LED
Into yokuqala ekufuneka uyiqwalasele xa ukhetha ibhodi yesekethe eprintiweyo ye-SMD LED yinkcazo ye-LED.Kubalulekile ukuqwalasela umbala wee-LED njengoko oku kuya kuchaphazela ukubonakala kweprojekthi.Ii-LED ze-SMD ziza ngemibala eyahlukeneyo kubandakanya obomvu, oluhlaza, oluhlaza okwesibhakabhaka, otyheli, omhlophe kunye nombala oguqula ii-RGB ze-RGB.
Ezinye iinkcukacha ekufuneka ziqwalaselwe ziquka ubungakanani kunye nokumila kwee-LEDs.Inokuba nefuthe kuyilo lonke lwenkqubo.Ii-LED ze-SMD ziza ngobukhulu obuninzi.Ezi sayizi ziyi-0805, 1206 kunye ne-3528 kwaye imilo ingaba ngqukuva, uxande okanye isikwere.
2. Amanqanaba okukhanya kwee-LEDs
Inqanaba lokukhanya kwe-LED likwayinto ebalulekileyo ekufuneka iqwalaselwe.Umgangatho wokukhanya uya kuchaphazela ubungakanani bokukhanya okukhutshwa yi-LED.Sinokulinganisa amanqanaba okukhanya ngokwemiqathango ye-lumens.Inokuqala ukusuka kwii-lumens ezimbalwa zee-LED zamandla aphantsi ukuya kumakhulu aliqela e-lumens yee-LED zamandla aphezulu.
3. Umbane kunye neemfuno zangoku
Ingqwalasela yesithathu xa ukhetha iibhodi zesekethe eziprintiweyo ze-SMD yi-voltage kunye neemfuno zangoku zeprojekthi.Ii-LED ze-SMD zifuna i-voltage ephantsi kunye ne-low current ukusebenza.Ezi mfuno zombane ophantsi zivela kwi-1.8V ukuya kwi-3.3V kunye neemfuno zangoku zivela kwi-10mA ukuya kwi-30mA.
Kubalulekile ukuqinisekisa ukuba amandla ombane kunye neemfuno zangoku zeprojekthi ziyahambelana nePCB.Ukukhetha iPCB enevoltheji ephantsi kakhulu okanye ephezulu kakhulu kunokonakalisa ii-LED okanye iPCB.
4. Ubungakanani bePCB kunye nokumila
Ubungakanani kunye nokumila kwe-PCB kukwayinto ebalulekileyo ingqalelo xa ukhetha i-SMD LED PCB.ubungakanani bePCB buya kuxhomekeka kwinani leeLED ezifunekayo kwiprojekthi.Kukwaxhomekeke kwisithuba esikhoyo kwi-PCB.
Kubalulekile ukuqwalasela ubungakanani kunye nokumila kwePCB ngokunxulumene noyilo lonke.Umzekelo, ukuba inkqubo iyaphatheka okanye iyanxitywa, iPCB encinci kunye necwebileyo inokufaneleka ngakumbi.
5. Iimpawu zoyilo
Kubalulekile ukuqwalasela iimpawu zoyilo lwe-SMD LED iibhodi zeesekethe eziprintiweyo.i-PCB inokubandakanya iimpawu ezifana nezixhasi ezidibeneyo, ezinokwenza lula inkqubo yoyilo kunye nokunciphisa inani lamacandelo.
6. Iingqwalasela zobushushu
Olunye uqwalaselo olubalulekileyo xa ukhetha ii-PCB ze-SMD ze-LED kulawulo lwe-thermal ye-LEDs.I-LED ze-LED ziyakwazi ukuvelisa ukushisa okukhulu, ngokukodwa ii-LED zamandla aphezulu.Ngoko ke, ulawulo olufanelekileyo lwe-thermal lubalulekile ukukhusela umonakalo kwii-LED kunye nokuqinisekisa ukusebenza kakuhle.
Xa ukhetha i-SMD LED PCB, kubalulekile ukuqwalasela conductivity thermal wezinto PCB.Iimpawu ezongezelelweyo zolawulo lwe-thermal, ezifana ne-thermal vias, ezinokuthi ziyimfuneko ukukhupha ukushisa kwii-LED, kufuneka ziqwalaselwe.
7. Iimfuno zokuvelisa
Iimfuno zokwenziwa kwee-SMD LED PCBs nazo kufuneka ziqwalaselwe.Oku kuquka imiba efana nobubanzi bomkhondo obuncinane kunye nepitch efunekayo kwiPCB.Unokongeza iinkqubo ezithile zokuvelisa, ezinje ngonyango lomphezulu okanye iplating, onokuthi uyifune.
Kubalulekile ukukhetha iibhodi zesekethe eziprintiweyo ze-SMD ze-LED onokuthi uzenze usebenzisa inkqubo yakho yokuvelisa kunye nezixhobo ozikhethayo.Oku kunokunceda ukuqinisekisa ukuba uvelisa i-PCB ngokuchanekileyo nangempumelelo, ukunciphisa umngcipheko weempazamo okanye iziphene.
8. Iimfuno zokusingqongileyo
Iimfuno zokusingqongileyo ze-SMD LED PCBs kufuneka ziqwalaselwe xa ukhetha i-PCB efanelekileyo.Oku kubandakanya izinto ezifana noluhlu lobushushu, ukuxhathisa ukufuma, kunye nokuvezwa kweekhemikhali okanye ezinye izinto zokusingqongileyo.
Ukuba usebenzisa inkqubo esekelwe kwi-LED kwindawo enzima, khetha i-SMD LED PCB enokumelana nokushisa okukhulu.
9. Ukuhambelana namanye amacandelo
Ukuhambelana kwe-SMD ye-PCB ye-LED kunye namanye amacandelo kwinkqubo nayo yinto ebalulekileyo yokuqwalaselwa.Oku kubandakanya ukuqinisekisa ukuba iPCB iyahambelana nesekethe yomqhubi kunye nonikezelo lwamandla.
