Ephrintiwe wesifunda ibhodi (I-PCB) ukusekelwa kwezingxenye zesekethe nezingxenye kumikhiqizo kagesi. Inikeza ukuxhumana kagesi phakathi kwezinto zesekethe namadivayisi. Ngokuthuthuka okusheshayo kobuchwepheshe be-elekthronikhi, ukuminyana kwe-PCB kuya ngokuya kukhula. Amandla we-PCB design ukumelana nokuphazanyiswa enza umehluko omkhulu. Ukuzijwayeza kufakazele ukuthi noma ngabe ukwakheka kohlelo lwesifunda kulungile futhi ukwakheka kwebhodi lesifunda kungalungile, ukuthembeka kwemikhiqizo kagesi kuzophazamiseka. Isibonelo, uma imigqa emibili emincane ehambisanayo ebhodini eliphrintiwe isondelene ndawonye, ​​kuzoba nokubambezeleka kwifomathi yesiginali yesiginali, okuholele emsindweni obonakalayo ekupheleni kolayini wokudlulisa. Ngakho-ke, lapho kuklanywa ibhodi yesifunda ephrintiwe, kufanele sinake indlela eyiyo, sithobele umthetho jikelele wokuklanywa kwe-PCB, futhi kufanele sihlangabezane nezimfuneko zedizayini yokulwa nokuphazamiseka.

Izimiso ezijwayelekile ze-PCB design

Ukuhlelwa kwezinto nokuhlanganisa izintambo kubalulekile ekusebenzeni kahle kwamasekethe kagesi. Ukuze kudizayinwe i-PCB esezingeni elifanele nezindleko eziphansi, kufanele kulandelwe imigomo ejwayelekile elandelayo:

1. Intambo

Imigomo ye-wiring imi kanje:

(1) Izintambo ezihambisanayo ezikhumulweni zokufaka nezokukhipha kufanele zigwenywe ngangokunokwenzeka. Kungcono ukufaka ucingo oluphansi phakathi kwezintambo ukugwema ukuhlangana kwempendulo.

(2) Ububanzi obuncane bocingo lwe-PCB bunqunywa kakhulu ngamandla wokunamathela phakathi kocingo nokuvikela i-substrate nenani lamanje eligeleza ngabo. Lapho ukushuba kocwecwe lwethusi kungu-0.5mm nobubanzi bungu-1 ~ 15mm, okukhona nge-2A, izinga lokushisa ngeke libe ngaphezu kuka-3 ℃. Ngakho-ke, ububanzi bocingo lwe-1.5mm bungahlangabezana nezidingo. Kumasekethe ahlanganisiwe, ikakhulukazi amasekethe edijithali, kukhethwa kaningi ububanzi bocingo olungu-0.02 ~ 0.3mm. Vele, lapho kunokwenzeka, sebenzisa izintambo ezibanzi, ikakhulukazi izintambo zikagesi nezingaphansi. Isikhala esincane sezintambo sinqunywa kakhulu ukumelana namandla wokwahlukanisa namandla okuwohloka phakathi kwezintambo esimweni esibi kakhulu. Kumasekethe ahlanganisiwe, ikakhulukazi amasekethe edijithali, isikhala singaba ngaphansi kuka-5 ~ 8mil inqobo nje uma inqubo ivuma.

(3) Okuphrintiwe kwentambo okugoqiwe ngokuvamile kuthatha i-arc eyindilinga, futhi i-Angle engakwesokudla noma i-Angle efakwe kumjikelezo omkhulu wesifunda izothinta ukusebenza kukagesi. Ngaphezu kwalokho, gwema ukusebenzisa ucwecwe olukhulu lwethusi ngangokunokwenzeka, ngaphandle kwalokho, uma kufudunyezwa isikhathi eside, ucwecwe lwethusi kulula ukunwehla futhi luwe. Lapho kufanele kusetshenziswe izindawo ezinkulu zoqweqwe lwethusi, kungcono ukusebenzisa igridi. Lokhu kuvumela ukususwa kocwecwe lwethusi kanye nokuhlanganiswa kwe-substrate phakathi kokushisa okukhiqizwa yigesi eguquguqukayo.
