Gwaro Rekusarudza Vagadziri veAluminium LED PCB

Kusarudza mugadziri we LED PCB wearuminiyamu isiriyo hakuwanzoonekwa pakutanga. Inoonekwa mushure memwedzi mitanhatu sezvo magetsi adzoka, kuchenesa pasi pekupisa, kana kuti ma LED arrays ari kupisa 15°C kupfuura zvaifungidzirwa. Panguva iyoyo chigadzirwa chacho chatove kutumirwa. Gwaro iri rinopa mainjiniya ekutenga nemapoka ezvigadzirwa zvinodiwa pakuongorora mugadziri - vasati vazvipira kuwedzera.

MaPCB eAluminium LED haasi mabhodhi eFR-4 ane zvinhu zvakasiyana. Chidimbu chedielectric chinobatanidza mhangura nearuminiyamu chinoita zvakasiyana ne standard prepreg pasi pekudzvanywa, chinoita zvakasiyana ne drill tooling, uye chinoda solder mask chemistry yakasiyana. Fekitori inoshandisa FR-4 sechigadzirwa chayo chikuru inogara ichiburitsa mhedzisiro shoma paaruminiyamu - kwete nekuda kwechinangwa, asi nekuti ma process parameters akagadzirirwa zvinhu zvisiri izvo.

Mugadziri ane hunyanzvi anochengetedza mutsetse wekugadzira wePCB dzesimbi , ane mapurogiramu ekudzvanya akagadzirwa nearuminiyamu, maturusi, uye maitiro ekuongorora anouya e dielectric layer.

Zvitupa Zvinotsanangura Kugona Kwechokwadi Kwekuita

ISO 9001 ipasi kwete denga. Kune maPCB e LED ealuminium anoshandiswa zvakanyanya:

• IATF 16949 — inodiwa kune chero gungano re LED rinopinda mubhiri rezvinhu zvemotokari
• ISO 13485 — inodiwa pachiedza chekuvhiya, kuvhenekesa endoscope, kana michina yekuongorora
• UL 94V-0 — chiyero chekudzivirira moto chezvinhu zve dielectric; simbisa kuti zvinofukidza giredhi chaiyo iri kushandiswa
• IPC-6012 Kirasi 2 / Kirasi 3 — inotsanangura zvinodiwa kuti bhodhi rapera rigamuchirwe nemabhodhi akaomarara anosanganisira simbi

Kumbira zvitupa zviripo zvine mazuva ekuongorora uye zvirevo zvebasa. Chitupa chakapera mwedzi gumi nemana yapfuura kana chine kero yakasiyana yenzvimbo hachishande. Highleap Electronics ine zvitupa zviripo zveISO neIPC — tarisa basa redu rezvitupa.

Zviratidzo zveMidziyo: Zvinofanira Kuva Nenzvimbo Yekugadzira

Kumbira runyorwa rwemidziyo uye ruzivo rwekufanirwa kwekugadzirisa. Mutsetse usina kumbobvira wagadzirisa 3.0 W/m·K dielectric haugone kutaura kuti unokwanisa kuishandisa zvisinei nekuti zvinhu zvacho zviri paodha yekutenga here.

Zvikumbiro zveKufambisa Kwekupisa vs. Data reKuedza Rakanangana neLot

Mufananidzo wekupisa uri papepa re data unotsanangura dielectric iri yoga mumamiriro ezvinhu akanaka ekurabhoritari. Chinokosha kune chigadzirwa chako che LED ibhodhi rakaunganidzwa resistance yekupisa (θ_board): inoyerwa kubva pa copper pad kusvika paaruminiyamu ne calibrated heat source.

Chikumbiro kubva kune chero mugadziri anofanirwa kuita basa iri:

1. Ndezvipi zvigadzirwa zve dielectric uye magiredhi azvo? (Bergquist GP series, Ventec VT-4B2, Shengyi ST115G, kana generic isina zita?)
2. Ruzivo rwekuyedza kupisa rwakasiyana-siyana rwechikamu che dielectric chakagoverwa kuodha yako
3. Nzira yekuongorora inouya ye dielectric rolls — inoonekwa chete, kana kuti impedance/thermal spot-check?

Dielectric ye 2.0 W/m·K inogona kuyedza chero kupi zvako kubva pa 1.6 kusvika 2.4 W/m·K mumabheti ekugadzira. Kuchinja uku kunoshandura tembiricha ye LED junction ne 8–12°C mu high-bay fixture yakajairika, zvichikurumidzisa kudzikira kwe lumen. Kunzwisisa mashandiro anoita MCPCB heat dissipation pa stack level kunokubatsira kubvunza mibvunzo yakakodzera padanho re quotation.

Kuenderana kweDielectric Layer: Kuchinja kweInvisible Yield

Ukobvu hwe dielectric hunodzora nzira nhatu dzakazvimiririra dzekutadza mu aruminiyamu LED PCBs:

• Kurwisa kupisa: dielectric yakatetepa = yakaderera θ, asi yakaderera voltage margin
• Kuvimbika kwepamusoro-soro: IPC neUL zvese zvinoda voltage yekudzivirira yakaedzwa; spec yakajairika i1500–3000 V
• Kubatana kwejoini yeSolder: dielectric inosiyana muukobvu pane panel inoisa warpage panguva yekudzoreredza, LED pad inovhurika

Mugadziri ane hunyanzvi anodzora ukobvu hwe dielectric kusvika mukati me ±10% kuburikidza nemapurogiramu ekudzvanya akagadziriswa uye kusimbiswa kwechikamu chakasiyana. Mabhodhi ari kunze kwehwindo iri anokundikana kungave pakupisa kana pamagetsi - dzimwe nguva zvese zviri zviviri. Usati wapedzisa kurongedza PCB yako yealuminium LED , simbisa kugona kwemugadziri (Cpk) kweukobvu hwe dielectric pahukuru hwebhodhi rako.

Kugona Kurema Kwemhangura Kwekushandisa Ma LED Akawanda

MaPCB e LED e aruminiyamu akajairika anoshandisa mhangura ye 1 oz (35 µm). Tambo dze LED mukurima miti, maindasitiri, kana UV curing dzinoda 2 oz kana 3 oz kuti dzibate 3–10 A per trace pasina kupisa kunokwikwidzana nebhajeti re LED rekupisa.

Fekitori isina plating yemhangura inorema mukati meimba icharamba maodha aya kana kupa vanhu vekunze danho replating - ichiputsa cheni yekudzora mhando. Tarisa huwandu hwehuremu hwemhangura, saizi yepamusoro yepaneru pahuremu hwega hwega, uye kana mugadziri akaedza kuramba kwetrace paukobvu hwemhangura hwavanoda.

Gedhi reKufanirwa kweMuenzaniso

Hapana zvinotsiva magwaro ekushandisa pakugadzira prototype. Usati watanga kugadzira vhoriyamu:

1. Tumira mafaira eGerber kuti aite basa re DFM wongororo — izvi zvine chekuita nehupamhi hwetrace, annular ring, uye dielectric clearance zvisati zvava zvikanganiso pakugadzirwa.
2. Odha prototype yezvikamu zvishanu kusvika gumi ine mushumo wekuyedza kwemagetsi, mufananidzo wechikamu chakasiyana, uye data repamusoro-soro rinosanganisira
3. Enzanisa prototype cross-section ne thermal simulation inputs yako kuti uone kuti dielectric thickness chaiyo inoenderana nezvinodiwa.

Mugadziri anopa ruzivo rwekutanga rwekuongorora asina kubvunzwa ari kushanda padanho rehunyanzvi. Munhu anoda kubvunzwa kana bvunzo dzakaitwa hadzina kuitwa. Verenga nezvemaitiro ese ekubatanidza PCB yealuminium LED kuti unzwisise kuti ndeapi mapoinzi edata anofanira kuperekedzwa neprototype kuendesa.

Kubvisa Vakwikwidzi Zvichibva Pamhinduro Dzekutanga

Zvinhu zvinotadzisa vanhu kuwana basa pakuongorora vavhoti:

• Haikwanise kugadzira chirevo cheIPC-6012 chazvino
• Dielectric inotorwa kubva kuvatengesi vasina kunyorwa pane chero database yezvinhu zvinozivikanwa
• Hapana kugona kwekuyedza hi-pot mukati meimba — mabhodhi anotumirwa pasina kusimbiswa kwevoltage yekuparadzanisa
• Nguva dzemutobvu dzinopfupika pane dzinogoneka pakugadzirwa kwepamusoro uye huremu hwemhangura.
• Hapana kugona kwechikamu chekuongorora ukobvu hwe dielectric mushure mekudzvanya

FAQ

Ndezvipi zvitupa zvinofanira kuva nemugadziri wearuminiyamu LED PCB? ISO 9001 inovhara zvinhu zvekutanga zvekutarisira mhando. IATF 16949 inodiwa pakushandisa ma LED emotokari. ISO 13485 inoshanda pamwenje wekurapa. IPC-6012 Kirasi 2 kana 3 inotsanangura kugamuchirwa kwebhodhi. UL 94V-0 inoshanda kune zvinhu zve dielectric.

Ndingasimbisa sei chikumbiro chemutengesi chekupisa? Kumbira mushumo wekuyedza wakanyatsotsanangurwa wehuwandu chaihwo hwe dielectric batch muodha yako. Kusiyana kukuru kupfuura ±15% kubva pamutengo wataurwa kunofanirwa kuratidzwa uye kutauriranwa muchibvumirano chekutenga senzira yekuramba.

Chii chinofanira kusanganisira prototype package yealuminium LED PCB? Mushumo wekuyedza magetsi (kuenderera mberi, kupatsanurwa, hi-pot), mufananidzo wechikamu unoratidza saizi ye dielectric ne copper layer, kuongorora pamusoro pechinhu, uye chero data reAOI output. Kuongorora kwekutanga kwenyaya kuIPC-6012 ndiyo reference standard.

Fekitori yeFR-4 inogona here kugadzira maPCB e LED ealuminium emhando yepamusoro? Dzimwe nguva, asi zvisingaenderane. Maturusi eAluminium, mapurogiramu ekudhinda, uye makemikari emasiki anosolder zvakasiyana zvakanyanya nemaitiro eFR-4. Mafekitori asina kugona kwesimbi kwakakosha anogadzira mhedzisiro inogamuchirika pamagadzirirwo ari nyore, anoshivirira uye mhedzisiro yakaipa pamagadzirirwo e LED anoda kupisa zvakanyanya kana kuti akanyatsonaka.
