Okokuqala kwavela ngo-1950 ibhodi elilodwa abakhiqizi baseChina China ukuqonda:

Umlando webhodi lesifunda elilodwa:

Ibhodi lesifunda eliphrintiwe elenziwe linye liwumkhiqizo owenziwe e-United States ngokuvela kwama-transistors ekuqaleni kwawo-1950. Ngaleso sikhathi, ukugcwala okuqondile kwe-foil yethusi kwakuyindlela yokukhiqiza eyinhloko.

Ngo-1953-1955, iJapane yasebenzisa ucwecwe lwethusi olwalungenisiwe ukwenza iphepha le-phenolic copper foil substrate okokuqala ngqa, futhi lalisetshenziswa kakhulu emsakazweni.

Ngo-1956, ngemuva kokuvela kwabakhiqizi bamabhodi wesifunda eJapan, ubuchwepheshe bokukhiqiza bephaneli elilodwa baqhubekela phambili ngokushesha.

Ngokuya ngezinto, ekuqaleni, iphepha le-phenolic yethusi substrate laliyinto esemqoka. Kodwa-ke, ngenxa yokwehla kwamandla kagesi okuphansi, ukumelana nokushisa okungashisi kahle, ukuphazamiseka nezinye izinto zempahla ye-phenolic ngaleso sikhathi, izinto ezinjenge-resin yephepha legesi ne-glass fiber epoxy resin zenziwa kancane kancane. Njengamanje, iphaneli elilodwa elidingwa yimishini yabathengi elisebenzisa cishe lithatha iphepha le-phenolic resin substrate.

Izici zebhodi lesifunda elilodwa:

Iphaneli elilodwa liku-PCB eyisisekelo kunazo zonke, izingxenye zigxile ohlangothini olulodwa nezintambo ngakolunye uhlangothi. Njengoba izintambo zivela ohlangothini olulodwa, lokhu sikubiza ngokuthi yi-TYPE ye-PCB eyodwa-emaceleni. Amasekethe okuqala kuphela asebenzise amabhodi anjalo ukulinganiselwa okuqinile kwamapaneli owodwa kusifunda sokuklama (ngoba uhlangothi olulodwa kuphela lwesifunda belungeke luwelewe futhi bekufanele lilinyazwe ngasendleleni ehlukile);

Umdwebo wezintambo zephaneli elilodwa ubuswa yi-Screen Printing, okusho ukuthi ukuvimba i-ejenti kuphrintiwe ebusweni bethusi, kwagxila ukuvimbela amamaki wokuphrinta we-solder, futhi ekugcineni ukucubungula ukucubungula kusetshenziselwa ukuqedela izimbobo zomhlahlandlela wezingxenye nezimo. eminye imikhiqizo ikhiqizwa ngamanani amancane nangezindlela ezahlukahlukene, inqubo yezithombe lapho kusetshenziswa iphethini nge-photosensitizer.

Lokhu okungenhla kumayelana nomlando webhodi lesifunda umkhiqizi webhodi le-pcb, yamukela ukubonisana kwakho ~
