Momwe mungasankhire pad yoyenera ya silicone?

Kuuma, makulidwe, ndi kutsekereza zonse ndizofunikira. Malingaliro a kampani CMAI INTERNATIONAL LIMITEDamawulula kusamvana mu kusankha.

Pamene zipangizo zamagetsi zikupita patsogolo kwambiri ndi miniaturization, kutaya kutentha kumakhala chinthu chofunika kwambiri cholepheretsa kudalirika kwa mankhwala. Monga chinthu chofunikira pakuwongolera matenthedwe, kusankha kwa mapepala otentha a siliconezimakhudza mwachindunji kutentha kwa kutentha ndi moyo wa zipangizo. Komabe, magawo azinthu pamsika ndizovuta, ndipo ogwiritsa ntchito nthawi zambiri amagwa m'kusagwirizana chifukwa chonyalanyaza zizindikiro zazikulu. Malingaliro a kampani CMAIINTERNATIONAL LIMITED(pamenepa amatchedwa CMAI), monga otsogola padziko lonse lapansi opangira zida zoyatsira moto, amasanthula mozama zinthu zazikuluzikulu za silicone thermal pad kusankha malinga ndi zaka zambiri zamakampani, kuthandiza ogwiritsa ntchito kupeŵa misampha wamba. 

Lingaliro lolakwika 1: Kusankha kuuma kumatengera chidziwitso chokha, kunyalanyaza kusinthasintha kwa zochitika zogwiritsira ntchito.

Kuuma kwa mapepala otentha a silicone(nthawi zambiri imawonetsedwa mu kuuma kwa Shore C) imayenera kusinthidwa mwamphamvu malinga ndi kapangidwe kachipangizo komanso kupanikizika:

Kuuma kochepa (20-50 Shore C): Yoyenera Foni yam'manjas, mapiritsi ndi zida zina zokhala ndi malo ocheperako komanso zida zomvera. Kupanikizika kwakukulu kumatha kudzaza malo osagwirizana ndikuchepetsa kukana kwamafuta.

Kuuma kwapakatikati (50-80 Shore C): Yoyenera zida zamafakitale kapena zochitika zomwe zimafunikira thandizo, monga ma seva kapena zamagetsi zamagalimoto pamalo onjenjemera, kuti apewe kulephera kwazinthu chifukwa cha kupanikizana kwakukulu.

CMAI amalimbikitsa: M'munsi kuuma, ndi bwino. M'pofunika kulinganiza zoyenera ndi structural mphamvu. Mwachitsanzo, gasket yomwe imakhala yofewa kwambiri imatha kuuma chifukwa cha kutulutsa kwamafuta a silicone pakapita nthawi yayitali, zomwe zimawonjezera kukana kwamafuta.

Lingaliro lolakwika 2: Makulidwe ndi "kukula kumodzi kumakwanira zonse", kunyalanyaza mgwirizano pakati pa kukana kwamafuta ndi kusiyana

Kusankha makulidwe kuyenera kuganizira izi:

Kudzaza kwa 1.Gap: Makulidwe a gasket ayenera kukhala nthawi 1.2 kusiyana kwenikweni (monga makulidwe a 1mm kwa kusiyana kwa 0.8mm) kuti muwonetsetse kulumikizana kwathunthu.

2.Thermal resistance optimization: Makulidwe amafanana ndi kukana kwamafuta. Ma gaskets owonda kwambiri (monga pansi pa 0.3mm) amafunika kuwonjezera ulusi wagalasi kuti alimbikitse kulimba, koma atha kusiya zina. Thermal Conductivity.

3.Surface tolerance compensation: Ngati malo okhudzidwa ndi osagwirizana, gasket yapamwamba yoponderezedwa iyenera kusankhidwa ndipo makulidwe ayenera kuwonjezereka moyenerera.

CMAInkhani: Makasitomala ena mwachindunji anasankha 0.5mm muyezo makulidwe silikoni matenthedwe conductive gasket popanda kuganizira cholakwika PCB kugwirizana, kuchititsa kutentha kwambiri m'deralo. Pambuyo CMAI adalimbikitsa kugwiritsa ntchito 1mm high compression gasket, kusiyana kwa kutentha kunachepetsedwa ndi 15%

Lingaliro lolakwika lachitatu: Kunyalanyaza magwiridwe antchito achitetezo kungayambitse ngozi

Pazida zamagetsi zothamanga kwambiri kapena zothamanga kwambiri, kutsekemera kwa mapepala otentha a siliconendizofunikira. CMAIamakumbutsa kuti makampani ena amasankha zinthu zosatsekereza kuti azitha kuyendetsa bwino matenthedwe, zomwe zingayambitse ngozi zazifupi. Mapangidwe apamwamba mapepala otentha a siliconeAyenera kukhala ndi ma conductivity apamwamba kwambiri (monga 1.5W/mK kapena kupitilira apo) komanso mphamvu yotchinjiriza magetsi (≥5kV/mm) kuti zitsimikizire chitetezo ndi magwiridwe antchito.

Mapeto

CMAIimayang'ana pa kafukufuku ndi chitukuko ndi kupanga mapepala otentha a silicone. Zogulitsa zake zimagwiritsidwa ntchito kwambiri pamagetsi, mphamvu, magalimoto ndi magawo ena, ndipo zimadziwika chifukwa chodalirika kwambiri komanso ntchito zosinthidwa makonda. Poyankha zosankha zosiyanasiyana zamakasitomala, CMAI wakhazikitsa osiyanasiyana silicone thermal padzopangidwa, zophimba kuuma kosiyanasiyana, makulidwe ndi milingo yotchinjiriza, ndikupatsa makasitomala zosankha zaukadaulo.
