(Gawo la ad ceramicOpangidwa ndiWntrustek)
Njira yothandizira chitsuloDBCTekinoloje. Pofuna kulumikizagawo la ceramicNdi chitsulo chochepa, zinthu zochepa kwambiri monga ti, zr, ndi cr mu zitsulo zojambula zimakhudzana ndi ceramic kuti mupange zomwe zimawonongeka ndi chitsulo chamadzimadzi. Cholinga cha chomangira chimakhala ndi cholumikizira kwambiri ndipo chimakhala chodalirika kuyambira pomwe zimakhazikitsidwa ndi mankhwala osokoneza bongo ndi makatani otentha.
Mmbuli ndiye njira yaposachedwa kwambirimagawo a ceramicndipo imapereka kuthekera kopanga mkuwa wogwiritsa ntchitoSilicon nitride (si3n4) or aluminium nitride (aln). Popeza ad ad amagwiritsa ntchito kutentha kwambiri kosasinthika kuti aletse mkuwa Woyera wa ceramic, njira yodziwikiratu sigwiritsidwa ntchito. Kuphatikiza apo, imapereka gawo lalikulu lodalirika kwambiri ndi chopatulikitsa chotentha.
Ntchito Yogwira Phraze ya PCB ya PCB ili ndi:
1. Magetsi apamwambakatundu
Zogwiritsa ntchito kwambiri, magawo a ceramic amatha kuchepetsa kusokonezedwa ndi kuwonongeka kwa dielect chifukwa cha kuchepa kwake komanso kutayika.
2. Kutentha Kwambiri
Zitsamba za Chuma ndizoyenera magwiridwe antchito apamwamba omwe amafunikira kuchezera kwamphamvu kotentha chifukwa magawo a ceramic ali ndi mawonekedwe abwino kwambiri opangira misempha.
3. Kuchulukirachulukira
Popanga kulumikizana kokhazikika komanso kosatha pakati pa zigawo zachitsulo ndi gawo lapansi gawo la ceramic, njira yogwira ntchito yachitsulo imatha kuwonjezera kudalirika kwa PCB.
4. Mgwirizano wamphamvu
PCB ya Ambs ili ndi ubale wolimba kuposa zigawo zina zongoyerekeza chifukwa zimachokera pazomwe zimapangitsa kuti zikhale ndi zigawo zamatenthedwe.
5. Zachuma
Gawo la ceramic limalandira utoto wosanjikiza kuchokera pa chitsulo chogwira ntchito, chomwe chingafupikitse nthawi zopanga PCB ndi mtengo wotsika.
Pansipa pali zinthu zina zogwiritsidwa ntchito kwambiri kwa amphaka:
1. Ambu Nsombaumina cgawo lapansi
Alyo3 Ceramics ndizotsika mtengo kwambiri komanso zopezeka. Ali ndi machitidwe otukuka kwambiri ndipo ndi gawo lotsika mtengo kwambiri la saramic. Khalidwe lawo limaphatikizapo kulimba mtima kwambiri, kuuma kwambiri, kukana kuwonongera, kukana kuvala, kulimba mtima mpaka kutentha kwambiri, komanso magwiridwe olimbikitsa.
Komabe, omvera a Alumina amagwiritsidwa ntchito kwambiri pakugwiritsa ntchito ndi kachulukidwe kakang'ono kamphamvu ndipo palibe zofunikira zolimbitsa thupi chifukwa cha kuchepa kwa matenthedwe ndi njira yobwezeretsa njira ya alumuramics.
2. Cholinga cha ALN
Chifukwa cha mawonekedwe ake owoneka bwino (mawonekedwe azomwe amachititsa thupi 319 w / (mue)), magetsi otsika kwambiri, ndipo mawonekedwe abwino amafananira ndi zitsulo za Alyoectonic kuposa zida za Alyo3 ndi Beo.
Pakadali pano, magetsi kwambiri ndi mphamvu zapamwamba kwambiri monga njanji zothamanga kwambiri, zosinthira zamagetsi zapamwamba, ndi magetsi a DC ndizofunikira kwambiri pazinthu za aluminide (amphan). Komabe, kugwiritsa ntchito magawo a mipata yamkuwa kwa Copy-aln kuli kochepa chifukwa ndi mphamvu zopanda pake, zomwe zimakhudzanso moyo wawo wautali komanso wochepa kwambiri.
3. Gawo la simentime
Wosanjikiza wamkuwa (mpaka 800μm), kutentha kwambiri, kusamutsa kwamphamvu, komanso mawonekedwe apamwamba (> 90w / (M · KE)) Makamaka, imatha kunyamula pang'onopang'ono kusamutsa kwaposachedwa komanso bwino kwambiri pamene kukula kwa mkuwa kumawonda pang'ono ndi gawo loonda simiyansi.
