Kodi Mungapange Bwanji Ma PCB Abwino Kwambiri? Buku Lofotokozera Zonse za Njira Zofunikira Zopangira Ma PCB

Njira Yopangira PCB

Gawo 1: Kutsimikizira Deta

Asanapange, wopanga PCB amatsimikiza deta yopangira bolodi yomwe kasitomala wapereka, kuphatikizapo kukula kwa bolodi, zofunikira pa ndondomeko, ndi kuchuluka kwa zinthu zomwe zagulitsidwa. Kupanga kumachitika pokhapokha atagwirizana ndi kasitomala.

Gawo 2: Kudula Zinthu

Malinga ndi zomwe kasitomala wapereka pakupanga bolodi, dulani matabwa opangira zinthu m'zidutswa zazing'ono zomwe zikugwirizana ndi zofunikira. Ntchito zapadera: mbale yayikulu → kudula malinga ndi zofunikira za MI → kudula mbale → kudula ngodya/kupukuta m'mphepete → kutulutsa mbale.

Gawo 3: Kubowola

Boolani mulifupi wa dzenje lofunikira pamalo oyenera pa bolodi la PCB. Ntchito zapadera: mbale yayikulu → kudula malinga ndi zofunikira za MI → kuyeretsa → kudula ngodya/kupukuta m'mphepete → kutulutsa mbale.

Gawo 4: Kumira kwa Mkuwa

Mkuwa wochepa umayikidwa pa dzenje lotetezera kutentha. Ntchito zapadera: kupukusa mopanda mphamvu → kupachika bolodi → chingwe chodzimira cha mkuwa chokha → kutsitsa bolodi → kulowetsa mu 1% diluted H2SO4 → kukulitsa mkuwa.

Gawo 5: Kusamutsa Chithunzi

Tumizani zithunzi kuchokera ku filimu yopangira kupita ku bolodi. Ntchito zapadera: bolodi la hemp → kukanikiza filimu → kuyimirira → kulinganiza → kuonekera → kuyimirira → chitukuko → kuyang'anira.

Gawo 6: Zojambulajambula

Choyikapo cha electroplate: wosanjikiza wa mkuwa wofunikira ndi wosanjikiza wagolide wa nickel kapena tini pa pepala la mkuwa lowonekera kapena khoma la dzenje la dongosolo la dera. Ntchito zapadera: mbale yapamwamba → kuchotsa mafuta → kutsuka kwachiwiri kwa madzi → kuwononga pang'ono → kutsuka kwa madzi → kutsuka kwa asidi → kupukuta kwa mkuwa → kutsuka kwa madzi → kuviika kwa asidi → kupukuta kwa tini → kutsuka kwa madzi → mbale yapansi.

Gawo 7: Kuchotsa Filimu

Chotsani chophimba chotsutsana ndi ma electroplating ndi yankho la NaOH kuti muwonetsetse chophimba chopanda ma electroplating.

Gawo 8: Kudula

Chotsani ziwalo zosagwiritsa ntchito magetsi pogwiritsa ntchito mankhwala ophera tizilombo.

Gawo 9: Chigoba cha Solder

Tumizani zithunzi za filimu yobiriwira pa bolodi, makamaka kuti muteteze dera ndikuletsa kusungunuka kwa zigawo ndi chitsulo pa dera.

Gawo 10: Silkscreen

Sindikizani zilembo zodziwika bwino pa bolodi la PCB. Ntchito zapadera: chigoba chosungunula chikatha kukonzedwa, chiziziritseni ndikuchiyimitsa, sinthani sikirini, sindikizani zilembo, kenako chiziritseni.

Gawo 11: Zala zagolide

Ikani gawo la nickel/golide la makulidwe ofunikira pa chala cha pulagi kuti chikhale cholimba komanso cholimba.

Gawo 12: Kupanga

Bowolani mawonekedwe omwe kasitomala amafunikira pogwiritsa ntchito nkhungu kapena makina a CNC.

Gawo 13: Kuyesa

Zolakwika zomwe zimachitika chifukwa cha ma circuits otseguka, ma circuits afupi, ndi zina zotero, zimakhala zovuta kuzizindikira poyang'ana maso ndipo zimatha kuyesedwa pogwiritsa ntchito flying probe tester.
