Monga bolodi yamagalasi, cholowa cha aluminium ndichonyamula cha PCB. Kusiyana ndi kuti madutsidwe matenthedwe aluminiyamu gawo lapansi ndi apamwamba kwambiri kuposa galasi gulu CHIKWANGWANI, kotero amagwiritsidwa ntchito mu zigawo mphamvu ndi zina sachedwa kutentha, monga kuyatsa anatsogozedwa, masiwichi ndi mphamvu drives.Here, ndi  anatsogolera zotayidwa pcb kodi pali kusiyana kotani pakati pa zotayidwa ndi fiberglass.

Kusiyana pakati pa zotayidwa gawo lapansi ndi fiberglass

Aluminiyamu vs. Fiberglass Fiberglass ndiye njira yomwe imagwiritsidwa ntchito kwambiri pama board, monga pepala lomwe limagwiritsidwa ntchito kwambiri la FR4.Limapangidwa ndi fiber yamagalasi ngati gawo lapansi, pambuyo poti mkuwa umalumikizidwa pakupanga mbale yovekedwa ndi mkuwa, pambuyo pamndandanda yobwezeretsanso kuti ipange board board yosindikizidwa.

Chojambula chamkuwa cha bolodi yagalasi chimakhazikika ndi bolodi yagalasi kudzera pa binder, yomwe nthawi zambiri imakhala utomoni. Bolodi ya fiberglass yokha imasungika ndipo imakhala ndi zinthu zina zotsekemera zamoto, koma matenthedwe ake otenthawa ndi osauka. Vuto la matenthedwe otentha a bolodi yamagalasi, gawo lina lazinthu zomwe zimafunikira kutaya kwanyengo nthawi zambiri zimayendera njira yotenthetsera kutentha kudzera m'mabowo.

Koma kwa LED, sikuti imangokhala yolumikizana mwachindunji ndi koziziritsira kutentha kwanyengo.Ngati dzenje limagwiritsidwa ntchito poziziritsa kutentha, zotsatira zake ndizochepa, chifukwa chake LED imagwiritsa ntchito gawo la aluminiyamu ngati bolodi lazoyang'anira.

Kapangidwe ka gawo lapansi la aluminiyamu limafanana kwambiri ndi mbale ya fiberglass, kupatula kuti fiber yamagalasi imalowetsedwa ndi aluminium.Pakuti aluminiyamu yokha imayenda, ngati aluminiyumu itakutidwa ndi mkuwa, imapangitsa dera lalifupi. binder mu gawo la aluminiyamu kuphatikiza ngati chinthu chomangirira, komanso zinthu zotchingira pakati pa mkuwa ndi mbale ya aluminiyamu. Makulidwe a binder atha kukhudza kutchinjiriza kwa mbaleyo, kutsekemera kocheperako sikabwino, nawonso wandiweyani zimakhudza kutentha conduction.

Kaya gawo la aluminium la nyali ya LED likuyendetsa

Monga tawonera kuchokera pamapangidwe a aluminiyamu pamwambapa, ngakhale zotayidwa ndizoyenda bwino, kutchinjiriza pakati pa zojambulazo zamkuwa ndi zotayidwa kumachitika ndi utomoni. Chifukwa chake, zojambulazo zamkuwa kutsogolo zimagwiritsidwa ntchito ngati dera loyenda, ndipo zotayidwa kumbuyo zimagwiritsidwa ntchito ngati zinthu zotenthetsera kutentha, kotero sizimalumikizidwa ndi zojambulazo zamkuwa kutsogolo.

Aluminiyamu imakutidwa ndi utomoni wamkuwa ndi utomoni, koma imakhala ndi magetsi osiyanasiyana.Kuphatikiza pa gawo lapansi la aluminiyamu, pali kotentha kwakukulu kwamagawo amkuwa, mbale iyi imagwiritsidwa ntchito popanga magetsi, mtengo wake ndi apamwamba kwambiri kuposa gawo la aluminium.

Zomwe zili pamwambazi zakonzedwa ndikufalitsidwa ndi ma aluminium subcate pcb ogulitsa. Ngati simukumvetsa, chonde tiuzeni ".
