Aluminium PCB yePanze LED Inoratidza | Waterproof uye Durable Solutions

Nhanganyaya kune Kunze kwe LED PCB Zvinodiwa

Magirazi ekunze e LED anoshanda mumamiriro ezvinhu akaomarara anoda mhinduro dzemabhodhi edunhu dzakagadzirwa. PCB yekunze ye LED inofanira kutsungirira kupisa kwakanyanya, kupindira kwehunyoro, kunaya kwemvura zvakananga, uye mwaranzi ye ultraviolet yakasimba uku ichiramba ichishanda zvakanaka. Izvi zvinoshungurudza nharaunda zvinokonzera njodzi dzekukundikana idzo substrates dzeFR4 dzakajairika dzisingakwanise kugadzirisa zvakakwana.

Tekinoroji yeAluminium PCB yave ndiyo nzira inoshandiswa muindasitiri yekushandisa zviratidziro zvekunze nekuda kwehunhu hwayo hwepamusoro hwezvinhu. Iyo PCB yeAluminium core inopa conductivity yekupisa kwakanyanya, kugadzikana kwemuchina, uye kuramba zvakatipoteredza kwakakosha pakuisa maLED ane simba guru. Kana yakagadzirwa nematanho akakodzera ekudzivirira mvura uye kurapwa kunodzivirira ngura, idzi MCPCB dzemhinduro dzeLED dzinopa kuvimbika kwenguva refu kunodiwa nekuisa kwekunze zvachose.

Thermal Management muPanze LED PCB Dhizaini

mukuru Kupisa Kupisa mutambo

Ma LED ane simba guru anogadzira zvinhu zvakawanda zvinopisa zvinokanganisa hupenyu hwechikamu uye mashandiro ekuratidzira. Magadzirirwo ePCB anopiswa nekupisa kwakanyanya anoshandisa aruminiyamu anowana hunhu hwekupisa huri pakati pe1.0 kusvika 3.0 W/mK, zvichienzaniswa ne0.3 W/mK yezvinhu zvakajairwa zveFR4. Kubatsira uku kwekupisa kunova kwakakosha kana kuiswa kwePCB dze LED dzekunze kuchishanda pasi pezuva rakananga nekupisa kwekunze kunodarika 40°C.

Iyo aluminium base inoshanda seyakasanganiswa kupisa yekuparadzira iyo inoitisa simba rekupisa kure ne LED junctions uye inoiparadzira mukati mebhodhi repamusoro. Muchina uyu unobvisa mahotspots enzvimbo akajairika muFR4-yakavakirwa kunze kwekuratidzira PCB dhizaini, zvichikonzera kuita kwakafanana kwe LED uye kuwedzera hupenyu hwekushanda.

Key Thermal Benefits

Aluminium substrates inopa mabhenefiti anoyerwa ekunze kwe LED application:

• Lower junction tembiricha -Inoshanda kupisa kupisa inochengetedza majenji e LED mukati meakanakisa ekushanda marengeti kunyangwe panguva yekunyanya kuratidzwa kwezuva
• Uniform tembiricha kugovera -Kupisa kupararira mukati mearuminiyamu base kunodzivirira kuita kusiyana pakati pezvinhu zve LED
• Yakawedzerwa chikamu hupenyu hupenyu -Kudzikisira kushushikana kwekushisa kunonotsa kuderedzwa kwe LED uye inochengetedza kupenya kutsanangurwa pamusoro pemakore ekushanda
• Passive kutonhora kunyatsoshanda – Superior thermal conductivity kazhinji inobvisa kudiwa kwemaitiro anotonhodza anoshingaira mumamiriro ekunze ari pakati nepakati

Dziviriro yeChimiro uye Yezvakatipoteredza yePanze LED PCB

Mechanical Kugadzikana pasi peEnvironment Stress

Kutenderera kwetembiricha yezvakatipoteredza uye kuratidzwa kwemwando kunogadzira kushushikana kwemagetsi kunotenderedza zvakajairwa PCB zvinhu. Zvivako zvisingadziviriri zvealuminium PCB zvinoratidza kushomeka kwekuwedzera kwemafuta, kuchengetedza kugadzikana kwematembiricha kubva -40°C kusvika +85°C. Uku kutendeseka kwechimiro kunodzivirira kusarongeka kwe LED uye inochengetedza maitiro ekutarisa mukati memwaka yakasiyana-siyana.

Iyo inherent mechanic simba yealuminium substrates inopa kupikisa kwakakosha pakumisikidzwa kwekunze zvichienderana nekuremerwa nemhepo uye kukwira kwevibrations. Kusiyana neinochinjika organic substrates, isina mvura aruminiyamu PCB magungano anochengetedza flatness yakatarwa yakakosha kune inowirirana LED yakatarisana madaro uye yunifomu yekugovera mwenje.

Corrosion uye UV Dziviriro Systems

Mamiriro ekunze anounza matambudziko anoramba achiita ngura kuburikidza nekufumurwa kwemunyu wekupfapfaidza, zvinosvibisa maindasitiri, uye condensation cycles. UV-inodzivirira PCB mashandisirwo anoshandisa akasarudzika epamusoro ekurapa ayo anogadzira zvipingamupinyi zvinoshanda kurwisa oxidation uye kurwisa kwemakemikari:

• Anodized aluminium coatings - Electrochemical surface conversion inogadzira yakaoma oxide layer inopesana nekunyorova uye kuratidzwa kwemakemikari
• Kudzivirira conformal coatings -Polymer layers inodzivirira mitsetse yemhangura uye majoini ekutengesa kubva kune zvinosvibisa zvakatipoteredza
• UV-yakagadzikana solder masks -Akasarudzika magadzirirwo anodzivirira kuparara kwemafotokemikari pasi pemwaranzi yezuva
• Edge sealing treatments -Kudzivirirwa kweborder kunodzivirira hunyoro kupinda mukati mebhodhi

Iyo aluminium base pachayo inoramba yakagadzikana mumakemikari pasi pekuratidzwa kweUV, ichipa hwaro hwechigarire hunobuda kunze kwemaitiro ekunze mumashandisirwo ekunze.

Waterproofing Design Strategies

Kuchengetedza hunyoro hunoshanda kunoda kurongeka kubatanidzwa kwezvinhu uye zvimiro zvekugadzira maficha. Mvura isina mvura aruminiyamu PCB maassemblies anoshandisa conformal coatings, silicone encapsulation, kana potting makomisheni kugadzira zvipingamupinyi zvinoenderera pamusoro pechikamu chepamusoro. Bhodhi-level dhizaini inosanganisa kuburikidza neplugging, kuvharwa chisimbiso, uye hurongwa hwechikamu chekuisa kudzikisira nzira dzekupinda kwemvura, zvichiita kuti IP65 kana IP67 ingress yekudzivirira ratings inokodzera kuisirwa zvachose kunze kwekunze.

Critical Construction Parameters

Yakakwana yekunze ye LED PCB kuita kunoenderana neiyo chaiyo substrate yakatarwa. Ukobvu hwebhodhi kazhinji hunobva pa1.0mm kusvika pa3.2mm, nealuminium base layers inosanganisira 1.0mm kusvika 2.0mm yehukobvu hwakazara. Iyo dielectric insulation layer pakati pemhangura yedunhu uye aluminium base inoyera zvakanyanya mashandiro ekupisa kupesana nemagetsi ega, nehukobvu hwakajairwa kubva pa75μm kusvika 150μm.

Copper foil uremu kusarudzwa kunogadzirisa ikozvino-inotakura zvinodiwa paunenge uchibata thermal mass. Imwe-ounce mhangura (35μm) inokwana kuronda masaini, ukuwo nzira dzemagetsi eLED dzepamusoro dzinoda maviri-ounzi (70μm) kana matatu-ounce (105μm) mataurirwo ekudzikisa kudonha kwevoltage uye kuderedza kudziyisa kwekudziya.

Surface Pedzisa uye Dziviriro Kurapa

Kusarudzwa kwepamusoro pekupedzisira kunokanganisa zvakanyanya kuvimbika kwenguva refu munzvimbo dzekunze. Electroless Nickel Immersion Goridhe (ENIG) inoburitsa kupfava kwepamusoro uye kuramba kwekuora kana ichienzaniswa neHot Air Solder Leveling (HASL), ichiita iyo sarudzo yakasarudzika yekunze kuratidza PCB application. Kuwedzera anodized coatings pane akafumurwa aruminiyamu nzvimbo inopa chechipiri chekuchengetedza nharaunda.

Environmental Qualification Testing

Kusimbiswa kwedhizaini kunofanirwa kusanganisira kukurumidza kuyedzwa kwezvakatipoteredza kunodzokorora makore ekuratidzwa kwekunze:

• UV exposure test -Kuenderera mberi kweultraviolet radiation kuratidzwa kunosimbisa kugadzikana kwejasi uye kuchengetedza kwemavara
• Kuongororwa kwemunyu -ASTM B117 protocol inoongorora kusagadzikana kwekuora munzvimbo dzemahombekombe
• Thermal cycling - Tembiricha yakanyanyisa kubva -40 ° C kusvika +85 ° C inosimbisa kuenderana kwezvinhu uye solder kubatana kutendeseka.
• Kuongororwa kwemvura ingress - IP rating verification inosimbisa kushanda kwekudzivirira mvura pasi pekumanikidzwa
