Metal Core PCB Dhizaini Mirayiridzo | Injiniya Mirayiridzo yeOptimal Thermal Performance

ziviso

Metal musimboti PCB dhizaini inomiririra yakakosha chirango cheinjiniya kune maapplication anoda epamusoro ekupisa kwekutonga masimba. Sezvo kuwanda kwemagetsi kuri kuramba kuchiwedzera mumasisitimu emwenje e LED, mota dzemagetsi, uye mamodule ekushandura magetsi, chikamu chekugadzira chabuda sechinhu chikuru chinotaridza kuita kwekushisa kwete kusarudzwa kwezvinhu chete.

Iri gwara rinotarisa pane einjiniya paramita inotsanangura yakabudirira Metal musimboti PCB dhizaini, kusanganisira marongero ehurongwa, kupisa nzira optimization, mhangura ukobvu kutsanangurwa, uye kupisa kuburikidza nekuita. Inoshanda yekupisa manejimendi PCB dhizaini inoda kurongeka kutariswa kwezvinhu izvi zvakabatana kubva padanho rekutanga repfungwa kuburikidza nekugadzira kusimbiswa.

Kunzwisisa Chinangwa Chekugadzira muMetal Core PCB Dhizaini

Icho chinangwa chakakosha cheMetal Core PCB dhizaini inopfuurira kupfuura yakapusa kupisa conduction kuti iwane yunifomu yekupisa yekugovera uchichengetedza kuvimbika kwenguva refu. Iwo matatu-layer chimiro chinosanganisira yemhangura yedunhu layer, thermally conductive dielectric, uye simbi base substrate inoisa chaiyo dhizaini zvipingaidzo izvo zvinofanirwa kugadziriswa kutanga mukutenderera kutenderera.

Dhizaini mainjiniya anofanirwa kuongorora kupisa sosi yekumisikidza, huremu hwemhangura inodiwa, uye michina yekumisikidza nzvimbo panguva yekuronga kwekutanga. Iyo simbi base inoshanda seyese inoparadzira kupisa uye chimiro chechimiro, ichida kunyatsotariswa kwemafuta ekuwedzera coefficients uye nzira dzekunamatira kune ekunze kupisa sinks.

Layout Dhizaini Mazano eThermal Optimization

Maitiro ekuisa zvikamu ndiwo hwaro hwekugadzirwa kweMetal Core PCB kunoshanda. Zvikamu zvine huwandu hwakawanda hwekupisa zvinofanirwa kuiswa munzira yekutanga yekuparadza kupisa , kazhinji pakati penzvimbo dzekuisa dzinobatana nemasisitimu ekutonhodza ekunze. Kupararira kwakafanana kwezvishandiso zvinogadzira kupisa kunodzivirira nzvimbo dzinopisa dziri munzvimbo imwe chete izvo zvinogona kukanganisa kuvimbika kwezvikamu uye kukurumidzisa kuora kwesistimu.

Strategic Component Placement

Zvishandiso zvekuyemura zvinopisa zvinopa nzwisiso yakakosha panguva yedanho rekugadzirisa, zvichibvumira mainjiniya kuona maitiro ekuyerera kwekupisa uye kuona zvingangoita mabhodhoro ekupisa asati azvipira kugadzira. Circuit trace wide uye copper foil ukobvu zvinopesvedzera zvakananga lateral kupisa kupararira mukati memhangura layer. Tsanangudzo dzakafara dziri padhuze nezvikamu zvemagetsi zvinofambisa kugovera kwemafuta panguva imwe chete ichitsigira huwandu hwazvino.

Heat Source Distribution Analysis

Zvikwata zvemadhizaini zvinofanirwa kumepu chimiro chekupisa chegungano rese, zvichiverengera kushanda kwakasimba-kwemamiriro uye zviitiko zvenguva pfupi zvinopisa. Zvikamu zvepedyo zvinofanirwa kuparadzaniswa nekufunga nezve thermal coupling mhedzisiro uye yakasanganiswa yekupisa mutoro pasimbi base substrate.

Via uye Thermal Path Dhizaini

Thermal vias inoshanda basa rakasarudzika muMetal Core PCB dhizaini nekugadzira yakatwasuka yekupisa yekuitisa nzira kuburikidza nedielectric layer kune simbi base. Kunyangwe mazhinji masimbi epakati mabhodhi anoshandisa single-sided mhangura wedunhu, zvine hungwaru kuiswa kweakazadzwa inopisa vias pasi pepamusoro-simba zvinodzikisira zvakanyanya kuramba kupisa. Rondedzero yemhando yekudziya vias inopa akawanda anoenderana kupisa nzira, zvinobudirira kudzikisa iyo yese yekupisa impedance.

Inokurudzirwa Via Specifications

Chiitiko cheinjiniya chinoratidza kupisa kuburikidza nemadhayamita ari pakati pe 0.3 ne 0.5 millimeters nepakati-kusvika-pakati spacing yemamirimita 1.0 kusvika 1.5 kuitira kunyatsoita basa. Copper plating ukobvu hwe35 kusvika 70 micrometer inova nechokwadi chekupisa kwakaringana uku uchichengetedza kugona kwekugadzira. Iyo via pateni density inofanirwa kukwidziridzwa mukati meiyo thermal pad nzvimbo iri pasi pemidziyo yemagetsi, nekutariswa kwakapihwa kune mechanical kusarongeka kweiyo dielectric layer.

Copper Ukobvu Sarudzo uye Trace Dhizaini

Huremu hwemhangura inomiririra yakakosha dhizaini sarudzo muMetal Core PCB dhizaini inobata zvese kupisa uye magetsi kuita. Yakajairwa LED uye yevatengi zvemagetsi maapplications anowanzo shandisa one-ounce mhangura (35 micrometer), ichipa yakakwana ikozvino kugona uye kupisa kupararira kwepakati simba mazinga. Magetsi emagetsi mamodules anoshanda pakukwirira kwazvino kunoda maviri kusvika matatu-ounzi mhangura (70 kusvika 105 micrometers) kudzivirira zvakanyanya resistive kudziyisa uye kugonesa inoshanda lateral kupisa kugovera.

Kuenzanisa Kuita uye Kugadzirwa

Mhangura inorema inovandudza kugona kwekutakura magetsi uye kufambisa kupisa asi inounza matambudziko mukuita kwephotolithography uye etching, zvingangoderedza upamhi hwetrace uye nzvimbo. Kuisa mhangura munzvimbo dzine magetsi akawanda kunopa nzira yekubvumirana, kuchengetedza kugona kwepitch munzvimbo dzezviratidzo ukuwo kuchisimbisa network dzekuparadzira magetsi. Mainjiniya ekugadzira anofanirwa kushanda pamwe chete nevanoshanda navo mukugadzira kuti vaone kuti kusarudzwa kwehukobvu hwemhangura kunoenderana nekugona kwekugadzira uye zvinodiwa zvekushivirira.

Dielectric Layer Kufunga

Iyo thermally conductive dielectric layer inoshanda seyekutanga kupisa bhodhoro muMetal Core PCB dhizaini, uye zvimiro zvayo zvinotarisisa kuzara kwemafuta kuramba. Dielectric layers ine yakakwirira thermal conductivity values ​​inodzikisira thermal impedance, kunyangwe magetsi ekudzivirira emagetsi uye voltage inomira zvakatemwa zvinoisa miganhu inoshanda. Typical dielectric thermal conductivity inotangira pa1 kusvika pa3 watts per metre-kelvin, ine ukobvu hunokosha huri pakati pe50 ne150 micrometers.

Mainjiniya anofanira kuyera zvinodiwa zvinokwikwidzana zvekudzivirira kupisa kushoma, simba guru re dielectric, uye kuvimbika kwenguva refu mumamiriro ezvinhu ekupisa. Kusarudzwa kwezvinhu zveMCPCB kunosanganisira kuchinjana pakati pekushanda kwekupisa nekuparadzaniswa kwemagetsi, kunyanya mukushandiswa kwemagetsi ane simba guru uko ukobvu hwe dielectric hwakawedzerwa hunova hunodiwa kuti kutevedzera kuchengetedzeka kuenderane nezvinodiwa.

Thermal Simulation uye Validation

Computational thermal analysis inofanirwa kubatanidzwa muMetal Core PCB dhizaini yekufambiswa kwekushanda kuti isimbise nzira dzekupisa kupisa isati yaitwa prototype yekugadzira. Zvishandiso zveSoftware senge ANSYS kana mamwe akafanana anogumira ekuongorora mapuratifomu anogonesa vagadziri kuenzanisira kupindirana kwekupisa uye kufanotaura tembiricha yejunction pasi pemamiriro akasiyana ekushanda. Makiyi ekuita metrics anosanganisira kupisa kwekupisa kubva pajunction kuenda kune imwe kesi uye tembiricha inotarisirwa kukwira pamusoro pemamiriro ekunze.

Validation Testing Protocols

Kusimbiswa kwemuviri uchishandisa infrared thermal imaging inosimbisa kufanotaura kwekufungidzira uye inozivisa nzvimbo dzisingatarisirwe dzinopisa mumagungano emuenzaniso. Masimba eku bhasikoro bvunzo anoongorora mashandiro ekushisa pasi pechokwadi anoshanda maprofile uye anoongorora kuvimbika kwenguva refu kuburikidza nekukurumidzira kuchembera mapuroteni. Hukama pakati pezvakayedzerwa uye zvakayerwa zvawanikwa zvinovaka chivimbo mumhando yekugadzira inopisa uye inotungamira kunatsiridza kune kunotevera dhizaini iterations.

Manufacturing Design Mafungiro

Dhizaini yemitemo yekugadzira inoshanda zvakaenzana pakugadzirwa kweMetal Core PCB sezvakaita macircuits akadhindwa, kunyange hazvo mabhodhi esimbi ane zvipingamupinyi zvakasiyana pakugadzirisa. Magadzirirwo emhangura akakora zvakanyanya, kupisa kwakanyanya kuburikidza nemapatani, uye kushivirira kwakasimba kunogona kukanganisa zvakanyanya goho rekugadzira uye mari yekugadzira. Kubatanidzwa kwekutanga nevagadziri vekugadzira kunoita kuti magadzirirwo ekugadzira aenderane nehunyanzvi hwekuita.

Maitiro Kuenderana Zvinhu

Copper etching chaiyo, dielectric layer lamination tolerances, uye kuenderana kwepamusoro pekupedzisira zvese zvinoda kuongororwa panguva yekuongororwa kwedhizaini. Mabatirwo epamusoro epamusoro anosanganisira organic solderability preservative uye electroless nickel kunyudzwa goridhe rinoramba richienderana nesimbi core substrates, kunyangwe maparamita ekuita angangoda kugadziriswa. Zvinyorwa zvekugadzira zvinofanirwa kujekesa zviyero zvakakosha, zvinodiwa zvenyama, uye maitiro ekuongorora kuti ive nechokwadi chekuenderana kwemhando yekugadzira.

mhedziso

Inoshanda Metal Core PCB dhizaini inoda yakarongeka uye inofambiswa nehuinjiniya maitiro ekudziya kwekutonga. Imwe neimwe dhizaini dhizaini-magadzirirwo ekugadzirisa, mhangura ukobvu, kupisa kuburikidza nedhizaini, uye dielectric kusarudzwa-inopa inopindirana kune iyo bhodhi kugona kwekushisa kwese uye kuvimbika kwenguva refu. Kuwana kuita kwakaringana kunoenderana nekuenzanisa zvinhu izvi mukati mezvipingamupinyi zvekugadzira.
