Tarihin Ci gaban PCB Board

Tun haihuwarPCB allon, ta ci gaba fiye da shekaru 70.A cikin tsarin ci gaba na fiye da shekaru 70, PCB ya sami wasu muhimman canje-canje, wanda ya inganta ci gaban PCB da sauri kuma ya sa ya yi amfani da sauri zuwa fannoni daban-daban.A cikin tarihin ci gaba na PCB, ana iya raba shi zuwa lokuta shida.

(1) Ranar haihuwar PCB.An haifi PCB daga 1936 zuwa ƙarshen 1940s.A cikin 1903, Albert Hanson ya fara amfani da manufar "layi" kuma ya yi amfani da shi a tsarin sauya tarho.Manufar wannan dabarar ita ce a datse foil din karfe mai sirara zuwa na'urorin da'ira, sannan a manna su a kan takardar paraffin, sannan a lika musu takardan paraffin, ta haka za a samar da tsarin tsarin PCB na yau.A cikin 1936, Dr. Paul Eisner da gaske ya ƙirƙira fasahar kere kere na PCB.Yawancin lokaci ana ɗaukar wannan lokacin azaman ainihin lokacin haihuwa na PCB.A cikin wannan tarihin tarihi, da masana'antu tafiyar matakai soma for PCB ne shafi hanya, fesa Hanyar, injin daskarewa Hanyar, evaporation Hanyar, sinadaran hadawa Hanyar da shafi Hanyar.A lokacin, ana amfani da PCB yawanci a cikin masu karɓar rediyo.

(2) Lokacin samar da gwaji na PCB.Lokacin samar da gwajin PCB ya kasance a cikin 1950s.Tare da ci gaban PCB, tun 1953, masana'antar kera kayan aikin sadarwa sun fara kula da PCB kuma sun fara amfani da PCB da yawa.A cikin wannan tarihin tarihi, tsarin masana'antu na PCB shine hanyar ragewa.Takamammen hanyar ita ce a yi amfani da takarda mai siriri mai siriri mai phenolic resin laminate ( PP material), sannan a yi amfani da sinadarai don narkar da foil ɗin tagulla da ba a so, ta yadda sauran foil ɗin tagulla su zama da'ira.A wannan lokacin, sinadarai na maganin lalata da ake amfani da su don PCB shine ferric chloride.Samfurin wakilci shine radiyon transistor šaukuwa wanda Sony ke ƙera, wanda shine PCB mai Layer Layer tare da PP substrate.

(3) Rayuwa mai amfani na PCB.An yi amfani da PCB a cikin 1960s.Tun daga 1960, kamfanonin Japan sun fara amfani da kayan tushe na GE (farin gilashin gilashin gilashin epoxy resin laminate) da yawa.A cikin 1964, kamfanin da'ira na gani na Amurka ya ƙera maganin plating na jan ƙarfe mara amfani (cc-4 bayani) don jan ƙarfe mai nauyi, don haka ya fara sabon tsarin ƙirar ƙari.Hitachi ya gabatar da fasahar cc-4 don magance matsalolin dumama nakasar warping da kuma cire jan karfe na gida Ge substrates a matakin farko.Tare da haɓakawar farko na fasahar kayan abu, ingancin kayan tushe Ge yana ci gaba da haɓakawa.Tun daga 1965, wasu masana'antun sun fara samar da samfuran Ge Substrates, Ge substrates don kayan lantarki na masana'antu da PP na kayan aikin lantarki na jama'a a Japan.
