A halin yanzu, Organic abu musamman domin epoxy guduro kayan a low farashin da kuma balagagge art ga mafi part har yanzu a PCB samar, da kuma na al'ada da kwayoyin buga kewaye hukumar daga kamanni biyu zafi masha'a da kuma thermal fadada coefficient matching jima'i, ba zai iya saduwa da bukatun na semiconductor kewaye hadewa kara habaka unceasingly.Ceramic abu yana da kyau high mita yi da lantarki yi, kuma yana da high thermal watsin, sinadaran da kwanciyar hankali da kuma thermal kwanciyar hankali na Organic substrates kamar ba su da kyau yi, shi ne wani sabon ƙarni na manyan sikelin Hadakar kewaye da kuma ikon lantarki dodon manufa marufi material.Therefore, a 'yan shekarun nan, Yumbu PCB Boardya samu m hankali da kuma m ci gaba.
Yumbu kewaye hukumar yumbu-tushen metallized substrate da kyau thermal da lantarki Properties, shi ne mai ƙarfi irin LED encapsulation, m abu, da shunayya haske, ultraviolet (MCM) da kuma shi ne musamman dace to da yawa guntu kunshe-substrates kamar kai tsaye bonding (COB) guntu encapsulation tsarin. a lokaci guda, shi kuma za a iya amfani kamar yadda zafi masha'a kewaye hukumar na wasu high-ikon ikon semiconductor kayayyaki, manyan halin yanzu canji, gudun ba da sanda, sadarwa masana'antu eriya, tace, hasken rana inverter, da dai sauransu
A halin yanzu, tare da ci gaba da high dace, high yawa, da kuma babban iko a cikin LED masana'antu a gida da kuma kasashen waje, ana iya gani daga 2017 zuwa 2018, da sauran m LED a samu babban cigaba, yana girma da iko, da ci gaban m yi zafi masha'a abu ya zama na gaggawa wajen magance matsalar da LED zafi dissipation.In general, LED luminous dace da kuma sabis rayuwa declines tare da karuwa da maha? ar zazzabi, idan maha? ar zafin jiki na 125 ℃ sama, da LED iya bayyana ko failure.In domin ya kiyaye LED zafin jiki a low zazzabi, high thermal watsin, low zafi juriya da kuma m marufi aiwatar dole ne a soma rage overall thermal juriya na LED.
Epoxy jan sanye substrates ne mafi yadu amfani substrates a gargajiya lantarki packaging.It yana da uku ayyuka: support, madugu kuma insulation.Its babban fasali su ne: low cost, high danshi juriya, low yawa, da sauki tsari, da sauki gane micrographics kewaye , dace da taro production.But a sakamakon FR - 4 tushe abu ne epoxy guduro, Organic abu na low thermal watsin, high zafin jiki juriya faƙĩri ne, don haka FR - 4 ba zai iya daidaita da high yawa, high ikon LED marufi da bukatun, kullum kawai a yi amfani da kananan ikon LED marufi.
Yumbu substrate kayan su ne yafi alumina, Aluminum nitride, Sapphire, High Borosilicate Glass, da dai sauransu Idan aka kwatanta da sauran substrate kayan, yumbu substrate yana da wadannan halaye a cikin inji Properties, lantarki Properties kuma thermal Properties:
(1) Mechanical Properties: Mechanical ƙarfi iya zama amfani da goyon bayan da aka gyara. Good aiki, high girma daidaito; Smooth surface, babu microcracks, lankwasawa, da dai sauransu
. (2) thermal Properties: The thermal watsin ne manyan, da thermal fadada coefficient aka dace da Si da GaAs da sauran guntu kayan, da kuma zafi juriya ne mai kyau.
(3) Banana Properties: The dielectric akai shi ne low, da dielectric hasãra ne kananan, rufi juriya da kuma rufi gazawar ne m, wasan kwaikwayon ne barga karkashin high zafin jiki da kuma high zafi, da kuma AMINCI ne high.
(4) Wasu Properties: Good sinadaran da kwanciyar hankali, ba danshi sha; Oil resistant da kuma sinadaran resistant. Non-mai guba, gurbatawa-free, alpha ray watsi ne kananan; The crystal tsarin ne barga, kuma shi ne ba da sauki canza a cikin zazzabi range.Abundant albarkatun kasa albarkatu.
Na dogon lokaci, Al2O3 ne babban substrate abu na high ikon packaging.But da thermal watsin na Al2O3 ne low, da kuma thermal fadada coefficient bai daidaita guntu material.Therefore, cikin sharuddan yi, kudin da kiyaye muhalli, wannan substrate abu ba zai iya zama mafi manufa abu ga ci gaban high-ikon LED na'urorin a nan gaba. Aluminum nitride tukwane da high zafi watsin, high ƙarfi, high juriya kudi, kananan yawa, low dielectric akai, wadanda ba mai guba, kazalika da kyau kwarai da kaddarorin kamar thermal fadada coefficient na daidai da tare da Si, za a hankali maye gurbin gargajiya high-ikon LED substrate abu, ya zama daya daga cikin alamar rahama gaba yumbu substrate kayan, samar da mafi girma daga 180W ~ 220w / MK, KingSong yayi yumbu buga kewaye allon for your PCB bukatun.
