Foromo ea Bokhoni ho Moralo oa PCB

Bokgoni bo ama polokelo ya eneji, ho sefa, nako, ho kopanya le ho loka ha matla ho pholletsa le sehlahiswa sa elektroniki. Moralong wa PCB, foromo ya motheo ke ntlha ya qalo feela: boitshwaro ba nnete bo boetse bo itshetlehile ka leeme la motlakase, mamello, ESR, ESL, ho bewa, le impedance e hlahisitsweng ke sebopeho.

Sengoloa sena se hokahanya foromo ea capacitance le liqeto tse sebetsang mabapi le khetho ea likarolo le kopano ea PCB.

Foromo ea Capacitance

Bokgoni bo hlaloswa e le C = Q / V , moo C e leng capacitance, Q e le tjhaja e bolokilweng, mme V e le motlakase. Bakeng sa sebopeho se setle sa poleiti e bapileng, capacitance e hakanyetswa ka C = epsilon A / d : permittivity e atisitsweng ka sebaka sa poleiti mme e arolwa ka sebaka sa karohano.

Likamano tsena li hlalosa hore na ke hobane'ng ha thepa ea dielectric, jeometri ea conductor, le sebaka sa sebaka li le bohlokoa likarolong le meahong ea PCB. Ha li bolele esale pele boitšoaro ba maqhubu a phahameng ba capacitor e kentsoeng.

Boitšoaro ba 'Nete ba Capacitor

Capacitor ea 'nete e kenyelletsa ho hanyetsa likokoana-hloko le ho kenella ha tsona. Ha maqhubu a ntse a eketseha, likokoana-hloko tseo li ka busa le ho theha ntlha e ikemetseng eo karolo e seng e sa sebetse e le karolo e ntle ea capacitive.

Hlahloba lintlha tsa karolo bakeng sa mamello ea capacitance, boitšoaro ba DC-bias, litšobotsi tsa mocheso, ESR, le li-curve tsa impedance. Sena se bohlokoa haholo ha MLCC li sebelisoa haufi le motlakase oa tsona o lekantsoeng kapa lits'ebetsong tsa mocheso o pharaletseng.

Ho arola le Botšepehi ba Matla

Li-capacitor tse arolang li fana ka maqhubu a makhutšoanyane a motlakase haufi le IC 'me li fokotsa motsamao oa motlakase seporong sa motlakase. Katleho ea tsona e angoa haholo ke selika-likoe se entsoeng ke capacitor, phini ea motlakase, ho khutla ha mobu le li-via.

• Beha di-decouplers tse nyane ka ho fetisisa tse nang le maqhubu a phahameng haufi le di-power pin tse loketseng.
• Sebelisa likhokahano tse khutšoane, tse pharaletseng le sefofane sa litšupiso se tsoelang pele moo ho khonehang.
• Khetha boleng ba capacitance ho tsoa tataisong ea IC le profaeleng ea tlhoko ea matla e lekantsoeng kapa e etsisitsoeng.

Bokgoni ba PCB ba Likokoana-hloko

Likarolo tsa koporo tse haufi le tsona li theha capacitance. Lipara tsa sefofane, mesaletsa holim'a lifofane tsa litšupiso, li-pad, le meaho ea lihokelo li ka susumetsa mathōko a matšoao, ho kopanya le impedance. Meralong ea impedance e laoloang, lintlha tsa stack-up le lipalo tsa field-solver li tšepahala ho feta melao ea matsoho.

Boloka matlooa a bonolo a arohane le li-node tse lerata tsa ho fetola, 'me u boloke tsela e hlakileng ea ho khutla e le hore likokoana-hloko tse ke keng tsa qojoa li se ke tsa baka khokahano ea lerata e sa lebelloang.

Khetho ea Likarolo le Kopano

Khetha liphutheloana tsa capacitor le mefuta ea dielectric ho tsoa ho motlakase o sebetsang, mefuta ea maqhubu, mocheso, botsitso bo hlokahalang, le lithibelo tsa kopano. Liphutheloana tse nyane haholo li fokotsa inductance ea ho kenya empa li ka ba bonolo haholoanyane ho flex petsoha haeba boto kapa ts'ebetso ea ho tlosa lipaneli e sa laoloe.

Mekhoa ea mobu, masoba a ho tjheseletsa, profaele ea ho phalla hape, le tšehetso ea boto li lokela ho hlahlojoa hammoho bakeng sa kopano e tšepahalang.

Tlhahlobo ea Moralo ka Highleap Electronics

Highleap Electronics e ka hlahloba mekhoa ea mobu oa capacitor, lithibelo tsa ho beha, tlhahisoleseling ea ho bokellana, le litlhoko tsa kopano pele ho tlhahiso. Ho fana ka li-rails tsa bohlokoa tsa motlakase le litlhoko life kapa life tsa impedance ho etsa hore tlhahlobo e tsepamise maikutlo haholoanyane.

Bakeng sa tlhahlobo ea ho iketsetsa lintho, kopa khotheishene ea PCB e nang le lifaele tsa Gerber, BOM, le lintlha tse amehang tsa moralo.
