4 Layer HASL Impedance Control Heavy Copper PCB
Ubwino Ndi Ntchito Za Heavy Copper PCB
Ntchito:
Kugwiritsa ntchito kwa PCB yamkuwa yolemera mu kutsimikizira kwa PCB kuli pafupifupi paliponse, ndipo ntchito yake ndi yotakata kwambiri, kuphatikizapo mitundu yonse ya zipangizo zapakhomo, zipangizo zamakono, zankhondo, zamankhwala ndi zina zamagetsi.Heavy copper PCB ili ndi ntchito yabwino yowonjezera, kutentha kwambiri, kutentha pang'ono, kukana kwa dzimbiri, kotero kuti zipangizo zamagetsi zimakhala ndi moyo wautali wautumiki, komanso kuchepetsa kuchuluka kwa zipangizo zamagetsi kumathandiza kwambiri.Makamaka, kufunikira koyendetsa magetsi apamwamba komanso zamakono zamagetsi zamagetsi ndizofunikira mkuwa wolemera.
Ubwino:
Mu kutsimikizira kwa PCB, PCB yamkuwa yolemera imakhala ndi mphamvu zabwino kwambiri komanso kusinthika kosinthika.Kuphatikiza apo, ndi oyeneranso njira zosiyanasiyana ndi machitidwe monga unit khoma mbale, lathyathyathya loko mtundu dongosolo, ofukula kuluma dongosolo, BEM dongosolo, mvula ngalande dongosolo, etc., ndipo angagwiritsidwenso ntchito zosiyanasiyana processing zofunika ndi machitidwewa. .
Makulidwe a Mkuwa Wamkati ≥4oz Kudzaza Njira
Kwa PCB yokhala ndi zojambulazo zolemera zamkuwa, kuti zitsimikizire kudzazidwa kwathunthu kwa guluu, utomoni wosindikiza kapena PP ufa nthawi zambiri umagwiritsidwa ntchito.Komabe, yankho ili lili ndi mavuto a ndondomeko yaitali ndi zovuta kulamulira makulidwe a dielectric wosanjikiza.Mapepala omatira a SP amatha kukwaniritsa zomwe zili ndi guluu wapamwamba komanso makulidwe ake.Ili ndi zabwino zambiri pakudzaza zomatira zamkuwa ndipo imatha kuthana ndi vuto la kudzaza kolimba kwa mkuwa.
Ubwino wa SP Prepreg
Kugwiritsa ntchito njira yolimbana ndi kutentha kwambiri, yokhala ndi kukana kutentha kwakukulu
Adopt low expansion coefficient system
Zomwe zili ndi utomoni wapamwamba kwambiri komanso porosity yabwino zimapangitsa kuti ikhale yodzaza bwino kwambiri
Magalasi apadera a fiber fiber amathetsa kupsinjika maganizo ndikuwongolera kudalirika.
