Tun farkon karni na 21, BGA mai karfin gaske, kwalin matattara mai kunshi da kunshin kayan kwalliya masu kwalliya da yawa da aka buga bisa tsarin kayan laminate masu ci gaba sun bunkasa cikin sauri.

Tarihin PCB a China

A cikin 1956, China ta fara haɓaka PCB.

A cikin shekarun 1960, samar da rukuni na rukuni guda, ƙaramin rukuni na samar da makaranta mai gefe biyu kuma ya fara haɓaka kwamiti mai yawa.

A cikin shekarun 1970, saboda iyakancewar yanayin tarihi a wancan lokacin, jinkirin ci gaban fasahar PCB ya sanya dukkanin fasahar kera baya ga ci gaban ƙasashen waje.

A cikin shekarun 1980, an gabatar da layukan samar da ci gaba na bangare guda, bangare biyu da kuma takarda da aka buga bangarori daban-daban daga kasashen waje, wanda ya inganta matakin fasahar samar da kayan bugawa a kasar Sin

A cikin shekarun 1990, masana'antun PCB na kasashen waje daga Hongkong, Taiwan da Japan sun zo kasar Sin don kafa kamfanonin hadin gwiwa da masana'antun mallakar su gaba daya, abin da ya sa kasar Sin ke samar da PCB da fasahar zamani cikin sauri.

A 2002, ya zama na uku mafi girma PCB mai samarwa.

A 2003, darajar fitarwa da yawan shigowa da fitarwa na PCB ya zarce mana dala biliyan 6, ya zarce Amurka a karon farko kuma ya zama na biyu mafi girman PCB a duniya. Hakanan ƙimar fitarwa ta ƙaru daga 8.54% a 2000 zuwa 15.30%, kusan ninki biyu.

A cikin 2006, China ta mamaye Japan a matsayin babbar masana'antar PCB a duniya ta hanyar darajar fitarwa da kuma kasar da ke kan gaba wajen fasahar kere kere.

A cikin 'yan shekarun nan, PCB ta kasar Sin ta ci gaba da samun ci gaba na kimanin kashi 20%, wanda ya fi ci gaban masana'antar PCB ta duniya girma sosai!
