Tarihin ci gaban PCB a China
A shekarar 1956, kasar Sin ta fara bunkasa PCB.
A cikin 1960s, an samar da panel guda ɗaya a cikin tsari, an samar da panel mai fuska biyu a cikin ƙananan ƙananan, kuma an samar da panel mai yawa.
A cikin 1970s, saboda ƙayyadaddun yanayin tarihi a wancan lokacin, haɓakar fasahar PCB ta kasance a hankali, wanda ya sa duk fasahar samar da kayayyaki ta koma baya ga ci gaban ƙasashen waje.
A cikin shekarun 1980s, an gabatar da layukan samar da PCB masu dumbin yawa masu gefe guda, masu fuska biyu da multilayer daga ketare, wanda ya inganta matakin fasaha na PCB a kasar Sin.
A cikin shekarun 1990, masana'antun PCB na kasashen waje irin su Hong Kong, Taiwan da Japan sun zo kasar Sin don kafa kamfanoni na hadin gwiwa da masana'antu gaba daya, wanda hakan ya sa masana'antar PCB ta kasar Sin ta samu ci gaba ta hanyar tsalle-tsalle.
A cikin 2002, ya zama na uku mafi girma na PCB.
A cikin 2003, ƙimar fitarwar PCB da ƙimar shigo da kaya da fitarwa ta wuce dalar Amurka biliyan 6, wanda ya zarce Amurka a karon farko kuma ya zama na biyu mafi girma na PCB a duniya.Matsakaicin ƙimar fitarwa na PCB ya ƙaru daga 8.54% a cikin 2000 zuwa 15.30%, kusan ninki biyu.
A shekara ta 2006, kasar Sin ta maye gurbin Japan a matsayin cibiyar samar da PCB mafi girma a duniya, kuma kasa mafi himma wajen bunkasa fasaha.
A cikin 'yan shekarun nan, Sin ta PCB masana'antu ya kiyaye wani m girma kudi na game da 20%, nesa da girma kudi na duniya PCB masana'antu.Daga shekarar 2008 zuwa 2016, darajar kayayyakin da ake samarwa a masana'antar PCB ta kasar Sin ya karu daga dalar Amurka biliyan 15.037 zuwa dalar Amurka biliyan 27.123, tare da karuwar karuwar kashi 7.65% a duk shekara, wanda ya zarta kashi 1.47% na yawan ci gaban da aka samu a duniya.Bayanai na Prismark sun nuna cewa, a shekarar 2019, darajar kayayyakin PCB na duniya ya kai dalar Amurka biliyan 61.34, wanda darajar PCB ta kasar Sin ta kai dala biliyan 32.9, wanda ya kai kusan kashi 53.7% na kasuwannin duniya.
