Nekuenderera mberi nekufambira mberi kwehunyanzvi hwechigadzirwa chemagetsi chemazuva ano, zvigadzirwa zvemagetsi zviri kukura zvishoma nezvishoma zvichienda kwakanangana nechiedza, chitete, chidiki, chakasarudzika, kuvimbika kwepamusoro uye mabasa mazhinji. Aluminium PCB yakazvarwa zvinoenderana nemaitiro aya. Aluminium PCB yakashandiswa zvakanyanya mumasekete akasanganiswa akasanganiswa, mota, otomatiki ehofisi, midziyo yemagetsi ane simba guru, midziyo yemagetsi uye mamwe minda ine kupisa kwakanakisa, machinability, kugadzikana kwedimensional uye kushanda kwemagetsi.
ProcessFlowof AluminiumPCB
Kucheka → gomba rekuchera → yakaoma firimu mwenje yekufungidzira → yekuongorora ndiro → kutema → kuongorora ngura → girini soldermask → silkscreen → kuongorora yakasvibirira → kupfapfaidza tin → aluminium base yepasi kurapwa → punching plate → kuongorora kwekupedzisira → kurongedza → kutumira
Zvinyorwa zvealuminiumpcb:
1. Nekuda kwemutengo wepamusoro wezvigadzirwa, isu tinofanirwa kutarisisa kune yakamira yekushanda mukuita kwekugadzira kudzivirira kurasikirwa nemarara kunokonzerwa nekukanganisa kwekushanda kwekugadzira.
2. The kupfeka kuramba pamusoro pamusoro aruminiyamu pcb murombo. Vashandi vega rega rega vanofanira kupfeka magirovhosi kana vachishanda, voatora zvinyoro nyoro kudzivirira kukwenya pamusoro peplate uye nealuminium base surface.
3. Imwe neimwe yemanyorero ekushandisa link inofanirwa kupfeka magirovhosi kuti isabate nzvimbo inobudirira yearuminiyamu pcb nemaoko kuti ive nechokwadi chekugadzikana kweiyo gare gare kuvaka kushanda.
Yakananga kuyerera kwealuminium substrate (chikamu):
1. Kucheka
l 1). Simbisa zvinhu zvinopinda zvekuongorora (inofanira kushandisa aluminium pevhu ine inodzivirira firimu sheet) kuve nechokwadi chekuvimbika kwezvinhu zvinopinda.
l 2). Hapana ndiro yekubikira inodiwa mushure mekuvhurwa.
l 3). Bata zvinyoro uye teerera kune kuchengetedzwa kwealuminium base surface (inodzivirira firimu). Ita basa rakanaka rekudzivirira mushure mekuvhura zvinhu.
2. Gomba rekuchera
l Kuchera paramita kwakafanana neiyo yeFR-4 sheet.
l Aperture kushivirira kwakasimba kwazvo, 4OZ Cu teerera kudzora chizvarwa chekumberi.
l Dhonza maburi neganda remhangura kumusoro.
3. Dry film
1) Kuongorora kwezvinhu zvinopinda: Iyo firimu yekudzivirira yealuminium base uso inofanira kuongororwa isati yagaya ndiro. Kana chero kukanganisa kunowanikwa, kunofanirwa kusungirirwa zvakasimba neblue glue isati yatanga kurapwa. Mushure mekunge kugadzirisa kwapera, tarisa zvakare usati wakuya ndiro.
2) Kukuya ndiro: chete mhangura yepamusoro inogadziriswa.
3) Firimu: firimu richaiswa kune zvese zviri zviviri mhangura uye aluminium base. Dzora kupindirana pakati peplate yekukuya uye firimu isingasviki 1 miniti kuti uone kuti tembiricha yefirimu yakagadzikana.
4) Kuombera: Teerera kune chokwadi chekuombera.
5) Kuratidzira: Kuratidzira mutongi: 7 ~ 9 kesi dzeglue yakasara.
6) Kuvandudza: kudzvinyirira: 20 ~ 35psi kumhanya: 2.0 ~ 2.6m / min, mumwe nomumwe anoshanda anofanira kupfeka magirovhosi kuti ashande zvakanaka, kuti arege kukwenya firimu rekudzivirira uye aluminium base surface.
4. Ndiro yekuongorora
1) Mutsetse wepamusoro unofanirwa kutarisa zvese zviri mukati zvinoenderana neMI zvinodiwa, uye zvakakosha kuita basa rekuongorora bhodhi.
2) Iyo aluminium base yepamusoro ichaongororwawo, uye iyo yakaoma firimu yealuminium base uso haizove nefirimu inodonha uye kukuvara.
Zvinyorwa zvine chekuita nealuminium substrate:
A. Plate nhengo yeplate yekubatanidza inofanira kutarisisa kuongororwa, nekuti hapana chakanaka chingatorwa kuti chikuya zvakare, nekuti kukwizwa kunogona kunhongwa nejecha (2000#) jecha robva ratorwa kunokuya ndiro, manual participation in the link of iyo ndiro ine hukama nebasa rekuongorora, nekuti iyo aluminium substrate inokodzera mwero yakawedzera zvakanyanya!
B. Panyaya yekurega kugadzirwa, zvinodikanwa kusimbisa kuchengetedza kuti ive nechokwadi chekutakura kwakachena uye tangi remvura, kuitira kuti ive nechokwadi chekuzogadzikana kwekushanda uye kumhanya kwekugadzira.
