PCB Intshayelelo
Ibhodi yesekethe eprintiweyo yenziwe ipleyiti esezantsi ekhuselayo, intambo yokudibanisa kunye nephedi yokudibanisa kunye ne-welding yezixhobo ze-elektroniki, kwaye inemisebenzi emibini yesekethe ye-conductive kunye ne-insulating bottom plate.Inokuthi ithathe indawo ye-wiring enzima kwaye iqonde uxhulumaniso lombane phakathi kwamacandelo ahlukeneyo kwisekethe.Ayinakwenza lula ukudibanisa kunye nokuwelda kweemveliso ze-elektroniki, inciphisa umthwalo wocingo ngendlela yemveli, kwaye inciphisa kakhulu ukuqina kwabasebenzi;kwakhona kunciphisa umatshini uVolume ngokubanzi, ukunciphisa iindleko zemveliso, kunye nokuphucula umgangatho kunye nokuthembeka kwezixhobo zombane.Ibhodi yesekethe eprintiweyo inokuhambelana kakuhle kwemveliso, kwaye inokwamkela uyilo olusemgangathweni, olulungele ukufezekiswa komatshini kunye ne-automation kwinkqubo yokuvelisa.Ngexesha elifanayo, yonke ibhodi yesekethe eprintiweyo edibeneyo kwaye ihlanjululwe ingasetyenziselwa njengenxalenye ezimeleyo yokuphumla ukuququzelela utshintshiselwano kunye nokugcinwa kwayo yonke imveliso.Okwangoku, iibhodi zeesekethe eziprintiweyo zisetyenziswe ngokubanzi kakhulu ekwenzeni iimveliso ze-elektroniki.
Iibhodi zeesekethe zokuqala eziprintiweyo zasebenzisa iibhodi eziprintiweyo ezenziwe nge-copper-clad.Ukususela ekuveleni kwe-semiconductor transistors kwiminyaka ye-1950, imfuno yeebhodi eziprintiweyo inyuke ngokukhawuleza.Ngokukodwa, uphuhliso olukhawulezayo kunye nokusetyenziswa okubanzi kweesekethe ezidibeneyo zenze umthamo wezixhobo ze-elektroniki zibe zincinci kwaye zincinci, kwaye ukuxinana kunye nobunzima bee-wiring zesekethe ziye zaba zikhulu ngakumbi, ezifuna ukuhlaziywa okuqhubekayo kweebhodi eziprintiweyo.Okwangoku, iindidi zeebhodi eziprintiweyo ziye zaphuhliswa ukusuka kwiibhodi zecala elilodwa ukuya kwiibhodi eziphindwe kabini, iibhodi ezininzi kunye neebhodi eziguquguqukayo;Ulwakhiwo kunye nomgangatho ziphuhliselwe ukuxinana okuphezulu kakhulu, ukuguqulwa kweminiaturization kunye nokuthembeka okuphezulu;iindlela ezintsha zokuyila, unikezelo loyilo kunye nezinto zokwenza iBhodi kunye nobuchule bokwenza ibhodi ziyaqhubeka ukuvela.Kwiminyaka yakutshanje, uyilo olwahlukeneyo oluncediswa yikhompyuter (CAD) ibhodi yesekethe eprintiweyo yesoftware yesicelo sele isaziwa kwaye yakhuthazwa kushishino.Phakathi kwabavelisi beebhodi ezishicilelo ezikhethekileyo, ukuveliswa koomatshini kunye nomatshini ozenzekelayo kuthathe indawo yokusebenza kwezandla.
Imvelaphi
Umdali we-PCB ngu-Austrian Paul Eisler (uPaul Eisler), ngo-1936, waqala ukusebenzisa ibhodi yesiphaluka eprintiweyo kunomathotholo.Ngo-1943, abantu baseMelika babesebenzisa kakhulu obu bugcisa koonomathotholo basemkhosini.Ngowe-1948, iUnited States yavuma ngokusemthethweni le mveliso ukuze isetyenziswe kurhwebo.Ukususela phakathi kwiminyaka yee-1950, iibhodi zesekethe eziprintiweyo ziqalisile ukusetyenziswa ngokubanzi.Iibhodi zesekethe eziprintiweyo zivela phantse kuzo zonke izixhobo zombane.Ukuba kukho iindawo zombane kwisixhobo esithile, zonke zixhonywe kwiiPCB ezinobungakanani obahlukeneyo.Umsebenzi ophambili we-PCB kukudibanisa amacandelo ahlukeneyo e-elektroniki kwisekethe emiselwe kwangaphambili kwaye adlale indima yokuhanjiswa kwe-relay.Lunxibelelwano olungundoqo lwe-elektroniki lweemveliso ze-elektroniki kwaye yaziwa ngokuba "ngumama weemveliso zombane".
