Okokuqala wabonakala ngo-1950 ibhodi pcb elinye, elinye icala-PCB izinto ukusetyenziswa iphepha phenolic baxhasa ibhodi, ibhodi wesekethe emacaleni amabini ilula ukuqonda omabini amacala ukuba iintambo, ngaloo ndlela umahluko ngcono, iphaneli mkhulu ngaphezu kweengcamba ezi-2, iintambo kangakanani ubunzima kunye nexabiso, umxholo othile nceda ulandele abavelisi be-China baseChina :

Imbali yebhodi enye yesekethe:

Ibhodi yesekethe eprintiweyo yamacala-nye yimveliso ephuhliswe e-United States ngenkangeleko ye-transistors kwii-1950s zokuqala. Ngelo xesha, ukutsala ngokuthe ngqo kwefoyile yobhedu yayiyeyona ndlela iphambili yokuvelisa.

Ngo-1953-1955, i-Japan yasebenzisa i-foil yamazwe angaphandle ukwenza iphepha le-phenolic ye-foil substrate okokuqala, kwaye yayisetyenziswa kakhulu kunomathotholo.

Ngo-1956, emva kokuvela kwabavelisi beebhodi zesekethe eJapan, iteknoloji yokuvelisa iphaneli enye yaqhubela phambili ngokukhawuleza.

Ngokubhekisele kwimathiriyeli, kwinqanaba lokuqala, eyona nto iphambili yayiyiphepha le-phenolic copper fostr substrate. Nangona kunjalo, ngenxa yokugquma okuphantsi kombane, ukunganyangeki kakuhle kobushushu, ukugqwetha kunye neminye imiba yezinto ze-phenolic ngelo xesha, izinto ezinjenge-resin yephepha le-resin yeglasi kunye ne-fiber fiber epoxy resin zaphuhliswa ngokuthe ngcembe. Okwangoku, iphaneli enye efunwa ngoomatshini babathengi ngombane phantse yamkela iphepha le-phenolic resin substrate.

Iimpawu zebhodi yesekethe enye:

Iphaneli enye ikwi-PCB esisiseko, iinxalenye zigxilwe kwicala elinye kunye neengcingo kwenye.Since iingcingo zivela kwicala elinye kuphela, siyibiza le TYPE ye-PCB icala-linye.Izijikelezo zokuqala kuphela ezazisebenzisa iibhodi ezinjalo ngenxa izithintelo ezingqongqo zeepaneli ezizodwa kwisekethe yoyilo (kuba icala elinye kuphela lesekethe alinakugqithwa kwaye kwafuneka lenzelwe umgaqo ohlukileyo);

Umzobo wiring wepaneli enye ilawulwa kukuPrinta kweScreen, oko kuthetha ukuba ukuvimba iarhente kuprintwe kumphezulu wobhedu, kumiselwe ukuthintela amanqaku e-solder Printing, kwaye ekugqibeleni ukubetha ngenqindi kusetyenziselwa ukugqiba imingxunya yesikhokelo kunye neemilo. ezinye iimveliso ziveliswa ngamanani amancinci kwaye ngeendlela ezahlukeneyo, inkqubo yokufota apho kusetyenziswa khona ipateni yefotosensitizer.

Oku kungasentla malunga nembali yebhodi yesekethe kunye neempawu zokwazisa, ndiyathemba ukuba ndiza kuba nalo uncedo ~! umenzi webhodi yepcb, yamkela ukubonisana kwakho ~
