Maitiro Ekugadzira MaPCB Emhando Yepamusoro? Gwaro Rakazara reMatanho Akakosha Ekugadzira MaPCB

Maitiro Ekugadzira PCB

Danho 1: Kusimbiswa kweData

Mugadziri wePCB asati agadzira, anoongorora data rekugadzira bhodhi rakapihwa nemutengi, kusanganisira saizi yebhodhi, zvinodiwa pakugadzira, uye huwandu hwechigadzirwa. Kugadzira kunoenderera mberi chete mushure mekubvumirana nemutengi.

Danho rechipiri: Kucheka Zvinhu

Zvichienderana neruzivo rwemutengi rwekugadzira bhodhi, cheka mapuranga ekugadzira kuita zvidimbu zvidiki zvinoenderana nezvinodiwa. Mabasa chaiwo: ndiro hombe → kucheka zvinoenderana nezvinodiwa neMI → kucheka ndiro → kucheka kona/kukuya → kuburitsa ndiro.

Danho rechitatu: Kuboora

Boora dhayamita yegomba rinodiwa panzvimbo dzakakodzera pabhodhi rePCB. Mabasa chaiwo: ndiro hombe → kucheka zvinoenderana nezvinodiwa neMI → kuchekerera → kucheka pakona/kukuya pamucheto → kuburitsa ndiro.

Danho rechina: Kunyura kwemhangura

Kapepa katete kemhangura kanoiswa paburi rinodzivirira kupisa. Mabasa chaiwo: kukuya zvisina kunaka → kuturika bhodhi → tambo yekunyura mhangura otomatiki → kudzikisa bhodhi → kunyikwa mu 1% H2SO4 yakasanganiswa → kukora mhangura.

Danho rechishanu: Kutamisirwa kweMufananidzo

Tumira mifananidzo kubva pafirimu rekugadzira kuenda kubhodhi. Mabasa chaiwo: bhodhi rehemp → kudzvanya firimu → kumira → kurongeka → kuratidzwa → kumira → kugadzira → kuongorora.

Danho rechitanhatu: Kuisa Mifananidzo

Electroplate jira remhangura rine ukobvu hunodiwa uye jira regoridhe renickel kana tin pamadziro emhangura akavhurika kana gomba repateni yedunhu. Mabasa chaiwo: ndiro yepamusoro → kubvisa mafuta → kushambidza kwechipiri nemvura → micro corrosion → kushambidza nemvura → kushambidza neasidhi → kuputira mhangura → kushambidza nemvura → kunyudza neasidhi → kuputira netini → kushambidza nemvura → kuputira neasidhi → kuputira netini → kushambidza nemvura → ndiro yepasi.

Danho rechinomwe: Kubviswa kweFirimu

Bvisa layer yekudzivirira ma electroplating neNaOH solution kuti uratidze layer yemhangura isina circuit.

Danho rechisere: Kucheka

Bvisa zvikamu zvisina circuit uchishandisa chemical reagent.

Danho 9: Solder Mask

Tumira mifananidzo yefirimu regirini pabhodhi, kunyanya kuchengetedza dunhu uye kudzivirira kusungirirwa kwezvikamu zvine tin padunhu.

Danho 10: Sikirini yeSiriki

Dhinda mavara anozivikanwa pabhodhi rePCB. Mabasa chaiwo: mushure mekupedza kugadzika mask yekusolder, tonhodza womira wakadzikama, gadzirisa skrini, dhinda mavara, uye pakupedzisira gadzirisa.

Danho 11: Zvigunwe zvegoridhe

Isa rukoko rwenickel/goridhe rweukobvu hunodiwa pamunwe wepuragi kuti uwedzere kuoma kwayo uye kuramba kwayo kupera.

Danho 12: Kugadzira

Rova chimiro chinodiwa nemutengi uchishandisa mold kana CNC machine.

Danho 13: Kuedza

Zvikanganiso zvekushanda zvinokonzerwa nemasekete akavhurika, mashort circuits, nezvimwewo, zvakaoma kuona kuburikidza nekutarisa nemaziso uye zvinogona kuyedzwa uchishandisa flying probe tester.
