Ehe, asi zvinoderedzawo kutadza kushanda zvakanaka, kugadzirisa patsva, uye nguva yekubatanidza. Kuedza mashandiro kunowanzo batsira kune madhiraivha emota, mabhodhi e sensor, mabhodhi ekutaurirana, mabhodhi ekudzora, uye chero gungano rine mutengo wakakwira wekukundikana.

Mutengo wePCB werobhoti ungaderedzwa sei pasina kuderedza mhando?

Deredza mari kuburikidza nekupatsanura zviri nani, kurerutsa zvinhu zvakaunganidzwa, kuisa mapaneru, kuisa BOM muchimiro chakajairwa, kuchinjana kwakatenderwa, kuongorora DFM, kushandisazve zvinhu zvakagadziriswa, kuronga mabheti, uye kuyedza kwakakodzera. Dzivisa kucheka mhangura, kufukidza, kana kuongorora usingazive.

Ruzivo rupi runodiwa kuti pave nekotesheni chaiyo yePCB yerobhoti?

Mutengo chaiwo unoda mafaira ekugadzira, BOM, centroid, madhirowa ekuunganidza, stackup, zvinodiwa zve impedance, huremu hwemhangura, kupedzisa kwepasi, manotsi ekuputira, zvinodiwa zvekuyedza, mirairo yefirmware/programming, huwandu hwakanangana, uye cadence yekugadzira inotarisirwa.
