Mhando dzeCopper Coin Structure: Press-Fit, Embedded, uye Inlay Dhizaini

Nhanganyaya: Kunzwisisa Copper Coin PCB Zvimiro

Mukushandiswa kwesimba remagetsi e semiconductor uye high thermal density, tekinoroji yekugadzira coin copper yave yakakosha pakugadzirisa matambudziko ekupisa. Sezvo zvikamu zvichigadzira simba rakawanda, nzira dzechinyakare dzePCB dzekutarisira kupisa dzinosvika pamiganhu yadzo. Kubatanidzwa kwecoin coin copper kunogadzirisa izvi nekugadzira nzira dzakatsaurirwa dzekupisa dzinoendesa kupisa zvakananga kubva kumagetsi kusvika kuma heat sinks kana mabhesi esimbi.

Mhando nhatu dzekutanga dzemhangura coin dhizaini dzinotungamira kugadzirwa kwazvino: press-fit, yakamisikidzwa, uye inlay copper copper PCB dhizaini. Chimiro chega chega chinosiyana zvakanyanya mukuti mhangura inosanganiswa sei ne dielectric zvinhu, mhangura zvidimbu, uye substrates. Ichi chinyorwa chinopa mainjiniya edhizaini maitiro anoshanda ekusarudza iyo yakakodzera yemhangura coin chimiro kuti ienzanise mashandiro ekupisa, kuvimbika kwenguva refu, uye mutengo wekugadzira.

Mhedziso yeCopper Coin Structure Integration muPCBs

Iyo copper coin thermal management musimboti inotarisana nekutanga vertical heat conduction nzira. Kupisa kunoyerera kubva muchikamu kuburikidza nemari yemhangura yakananga kunheyo yesimbi, ichipfuura yakakwira yekupisa yekupikisa dielectric layer. Iyi nzira yakatwasuka inodzikisira nhanho-kune-kesi yekupisa kupisa kana ichienzaniswa neyakajairika PCB zvivakwa.

Musiyano wakakosha pakati pemhangura coin dhizaini misiyano iri muinterface bonding nzira. Press-fit zvimiro zvinotsamira pane mechanicha yekubata kudzvanywa, dzakamisikidzwa mhando dzinowana metallurgical bonding kuburikidza nelamination, uye inlay dhizaini inoshandisa chaiyo machining kune flush-yakaiswa thermal cores. Iyi misiyano yemusiyano inobata zvakananga kupisa impedance, mechanical stress kugovera, uye kugadzira kuoma.

Dzvanya-Fit Copper Coin Structure

Manufacturing Process

Dhinda-inokwana zviumbwa zvesimbi zvemhangura zvinoshandisa mechanical kupinza kuisa masilinda emhangura mumakomba ekutanga-akagayiwa mukati mePCB. Mari yemhangura inobata zvakanangana nemhangura yakatenderedza mafoil layers, ichimisikidza nzira dzekudziya pasina zvimwe zvekubatanidza zvinhu. Ukobvu hwesimbi hunobva pa1.0mm kusvika pa3.0mm, nemadhayamita anofananidzwa nechikamu chetsoka.

Zvakanakira Kubatsira

Iyi nzira yemhangura yekuumbwa kwesimbi inopa akawanda mabhenefiti ekugadzira:

• Mari yekugadzira yakaderera -Zvidiki zvekushandisa zvinodikanwa uchishandisa yakajairwa CNC milling michina inoderedza capital investment.
• Nguva pfupi yekutungamira -Hapana akasarudzika lamination cycles compress kugadzirwa masheti zvakanyanya.
• Easy serviceability -Mechanical gungano inobvumira kutsiva kwenzvimbo pasina kurasa mabhodhi ese.

Performance Limitations

Contact interface thermal resistance inodarika iyo yemetallurgically bonded dzimwe nzira. Iyo mechanic joint inounza impedance kubva kune microscopic air gap uye pamusoro roughness. Thermal cycling inokonzeresa mutsauko wekuwedzera kushushikana pane coin-to-cavity interfaces, zvinogona kusvibisa hutano hwekubatana pamusoro pekushanda kwakawedzerwa.

Maitiro echimiro

Press-fit copper coin zvimiro zvinowana kushandiswa munhare dzemagetsi mabhodhi, mota dzinodzora mamodule, uye maindasitiri edhiraivha maseketi uko kuri pakati nepakati kupera simba kunoitika. Iko kudhura-kushanda kunoita kuti chimiro ichi chitaridzike kune maapplication anoda emuno kuwedzeredzwa kwekupisa pazasi 50 W/cm².

Yakamisikidzwa Copper Coin Chimiro Type

Manufacturing Process

Magadzirirwo emhando yesimbi yemhangura anobatanidza mhangura mukati mePCB substrate kuburikidza nekupisa kwekumanikidzwa panguva yekumonera. Mari dzesimbi dzinoiswa zvakanaka mumichina yakacheneswa, dzozoiswa mu prepreg ne copper foil layers pasi pekupisa nekumanikidzwa kwakadzorwa. Maitiro aya anogadzira zvisungo zvesimbi pakati pemari ne internal copper layers.

Zvakanakira Kubatsira

Yakananga simbi-kune-metal bonding mune iyi yemhangura coin chimiro inopa mashandiro epamusoro:

• Yakanaka kupisa kupisa -Metallurgical bonding inobvisa mikaha yemhepo, kuderedza interface yekupikisa.
• Uniform stress distribution -Kupisa kunopararira zvakaenzana munzvimbo dzakabatanidzwa, kuderedza kupisa kwenzvimbo.
• High thermal cycling endurance -Inochengetedza kuvimbika kuburikidza neanopfuura mazana matatu emadhizaini mhiri -40°C kusvika 150°C mazinga.

Manufacturing Zvinodiwa

Kuoma kwekugadzira kunowedzera zvakanyanya kana zvichienzaniswa nemaitiro ekudhinda-fit. Chaiyo CNC yekumisikidza kurongeka inova yakakosha kudzivirira layer misalignment panguva yelamination. Iyo yakasarudzika maitiro inoda kudzorwa kudzvanywa uye tembiricha profiles, kuwedzera nguva yekugadzira uye kuwedzera mutengo weyuniti nemakumi matatu kusvika makumi mashanu muzana pamusoro pekudzvanya-inokodzera dzimwe nzira.

Maitiro echimiro

Yakamisikidzwa yemhangura yemhando zvimiro zvinoshandisa silicon carbide uye gallium nitride simba modules, server voltage regulator modules, uye 5G base station RF simba amplifiers. Kushanda kwemafuta kunoruramisa mitengo yepamusoro apo kuvimbika kwechikamu uye tembiricha yekushanda inokanganisa maitiro ehurongwa.

Inlay Copper Coin PCB Dhizaini

Manufacturing Process

Inlay copper coin PCB madhizaini anoshandisa precision slot machining kugadzira zvisaririra zvinogamuchira zvidhinha zvemhangura kubva kumusoro kana pasi pepasi. Iyo inlay yemhangura inogara yakapfava nemateru akatenderedza, ichibatanidza nendege dzakakora dzemhangura kuti dziumbe mahybrid ekupisa. Machining kushivirira kunofanirwa kuchengetedza zvirinani pane 0.05mm yekumisikidza kurongeka.

Zvakanakira Kubatsira

Inlay zvimiro zvinopa yakakwana yekupisa manejimendi kugona:

• Shortest thermal nzira -Kupisa kwakananga kuyerera kubva kuzvikamu kuenda kusimbi base kunoderedza tembiricha yekusangana.
• Maximum kupisa kupararira -Flush-yakaiswa dhizaini inogonesa imwe-side kana kaviri-mativi ekubvisa kupisa zvigadziriso.
• Peak thermal conductivity -Inosvika yakasimba yemhangura substrate kuita ine kushoma interface kuramba.

Kugadzira Matambudziko

Ichi chimiro chesimbi chemhangura chinoda yakanyanyisa machining iko uye nekuchenjerera kupisa kwekushushikana kwekushushikana panguva yekuungana. Dimensional control inova yakakosha kudzivirira warpage kana delamination pasi pekupisa bhasikoro. Iyo yakasarudzika yekugadzira maitiro inomisa kugadzirwa kune zvivakwa zvine advanced CNC kugona.

Maitiro echimiro

IGBT magetsi modules, DC-DC inoshandura mumotokari traction inverters, uye yakakwira-yazvino mota inotyaira inowedzera inlay copper coin PCB zvimiro. Zvishandiso zvinoda kubviswa kwekushisa kupfuura 100 W/cm² uku uchichengetedza tembiricha dzepazasi pazasi pezvikumbaridzo zvakakomba zvinopembedza mari yekugadzira.

Kuenzanisa Kuongorora: Copper Coin Structure Performance

Thermal Performance Kuenzanisa

Kupisa kwenzira kunowedzera zvishoma nezvishoma mumhando dzemhando dzesimbi dzemhangura. Dhizaini-inokwana dhizaini inopa hupfumi hwekupisa kwekusimudzira kune zvine mwero magetsi ekushandisa. Akamisikidzwa zvimiro kuenzanisa kuita uye mutengo kune mainstream simba semiconductors. Inlay zvigadziriso zvinowana yakakwana yekupisa conductivity kune yakanyanyisa simba densities.

Kuvimbika uye Mutengo Zvinhu

Kuvimbika kunoenderana zvakanyanya neiyo interface bonding mhando mune zvemhangura coin zvimiro. Yakamisikidzwa uye inlay madhizaini anoratidza yepamusoro yekupisa bhasikoro kutsungirira, inomira pamusoro pe 3000 kutenderera mukati meindasitiri tembiricha. Press-fit zvimiro zvinotaridza kuita kunogamuchirika kumacycles ebasa asinganyanyi kudiwa asi zvingangoda kudzikisira munzvimbo dzakanyanyisa.

Dhizaini Mafungiro eCopper Coin Structure Selection

Thermal Zvinodiwa

Thermal conductivity zvinodiwa zvinofanira kuenzana nemhangura coin ukobvu uye dhayamita. Mari dzakakora dzinoderedza kupisa kwekupisa asi kuwedzera kuoma kwekugadzira. Mainjiniya anofanirwa kuverenga inodiwa yekupisa impedance zvichibva pane chikamu chesimba dissipation uye inobvumirwa jena tembiricha kukwira.

Magetsi uye Mechanical Design

Kuparadzaniswa kwemagetsi kunoda kubvumidzwa kwakaringana pakati pechimiro chemari yemhangura uye zviratidzo zvechiratidzo kudzivirira capacitive coupling kana kuparara kwevoltage. High-voltage application ingangoda imwe dielectric spacing yakatenderedza coin perimeters. Mechanical simba rekufunga anosanganisira kuchengetwa kwemari pasi pekuzunguzika uye kupisa kwekuwedzera kusawirirana.
