Mu pepala ili, Yongmingsheng, wopanga aluminiyamu gawo la PCB , ayambitsa aluminiyamu gawo lapansi PCB. Tonsefe timadziwa kuti aluminium ndi mtundu wachitsulo wokhala ndi magetsi. Kodi ntchito ngati chuma PCB?

Izi ndichifukwa choti gawo la aluminiyamu limakhala ndi magawo atatu amapangidwe, monga: zojambulazo zamkuwa, zotchinga ndi zotayidwa zachitsulo. Popeza pali chosanjikiza, kodi chosanjikiza chachitsulo chingagwiritse ntchito zinthu zina kupatula zotayidwa? Monga mbale yamkuwa, chitsulo chosapanga dzimbiri, chitsulo mbale, mbale ya silicon yachitsulo, ndi zina zotani zomwe zimagwiritsidwa ntchito popanga gawo lazitsulo, kuphatikiza pakuganizira kutentha kwa kutentha, komanso ganizirani kuchuluka kwa matenthedwe azitsulo, kutenthetsa mphamvu, kulimba, kuuma, kulemera, dziko lapamwamba ndi mtengo ndi zina.

zotayidwa pachimake pcb

Ubwino wake wa gawo lapansi la aluminium ndi chiyani?

Ntchito yabwino yoletsa kutentha

Tsatirani zofunikira za chilengedwe cha RoHS

Zoyenera kwambiri pamachitidwe a SMT

Kutalika kwaposachedwa kwambiri

Mu kapangidwe ka kapangidwe ka dera, kufalikira kwa kutentha kumachitidwa moyenera, kuti muchepetse kutentha kwa gawo, kutalikitsa moyo wautumiki, kukonza kachulukidwe ka mphamvu ndi kudalirika;

Kuchepetsa msonkhano wa rediyeta ndi zida zina (kuphatikiza zida zamagetsi zamagetsi), kuchepetsa kuchuluka kwamagetsi, kuchepetsa zida zamagetsi ndi kusonkhana; Kuphatikiza koyenera kwa dera lamagetsi ndikuwongolera dera;

Sinthani gawo losalimba la ceramic kuti mukhale opirira bwino.

Anatsogolera Aluminiyamu pcb

Gulu la magawo a aluminium

Aluminiyamu yokhala ndi zokutira zamkuwa zimagawika m'magulu atatu:

General-cholinga zotayidwa m'munsi zamkuwa zokutira mbale, zotchinga wosanjikiza ndi epoxy galasi nsalu yolumikiza;

Zotayidwa m'munsi mkuwa atavala mbale ndi kutentha kwambiri madyaidya ndikuledzera, ndi kutchinjiriza wosanjikiza wapangidwa ndi matenthedwe madutsidwe epoxy utomoni kapena resins ena;

Zotayidwa m'munsi mkuwa atavala mbale kwa pafupipafupi dera, chimateteza wosanjikiza ndi polyolefin utomoni kapena polyimide utomoni pepala galasi nsalu yomangira.

Cholinga chachikulu

Zogulitsa nyali, zida zamphamvu zamagetsi zanyali.

Zida zomvera, zotsogolera patsogolo, zokulitsira mphamvu, ndi zina zambiri.

Zida zamagetsi, ma DC / AC otembenuza, ma Bridges okonzanso, yolimba yolandirana, etc.

Zida zolumikizirana, ma amplifiers othamanga kwambiri, zida zosefera, dera lotumiza.

Zomwe zili pamwambazi zakonzedwa ndikufalitsidwa ndi PCB wogulitsa gawo la aluminium.Ngati simukumvetsetsa, tilandireni kuti tiuzeni "
