Umlando Wokuthuthukiswa Kwe-PCB Yomhlaba

Amabhodi wesifunda aphrintiwe aqala ukusetshenziswa kumadivayisi omsakazo ngo-1936 ngu-Paul Eisler wase-Austrian, umdali wabo.

Ngo-1943, abantu abaningi baseMelika basebenzisa ubuchwepheshe emisakazweni yezempi.

Ngo-1947, iNASA kanye ne-American Bureau of Standards baqala uchungechunge lokuqala lobuchwepheshe kwi-PCB.

Ngo-1948, i-Invention yamukelwa ngokusemthethweni e-United States ukuze isetshenziselwe ukuhweba.

Ngasekuqaleni kweminyaka yama-1950, kwaxazululwa izinkinga zamandla okubambelela nokumelana nokushisela kweCOPPER Foil kanye ne-laminate yeCCL, ngokusebenza okuzinzile nokwethembekile, futhi ukukhiqizwa okukhulu kwezimboni kwagcwaliseka. Ithusi ucwecwe etching kwaba ezivamile PCB yokukhiqiza ubuchwepheshe, futhi single ukukhiqizwa panel kwaqalwa.

Ngawo-1960, imbobo yensimbi emaceleni omabili yatholakala futhi ukukhiqizwa ngobuningi kwagcwaliseka.

Ngawo-1970, i-PCB enezingqimba eziningi yathuthuka ngokushesha, futhi yathuthukiswa ngokuqhubekayo isiqondiswa ngokunemba okuphezulu, ukuminyana okuphezulu, imbobo yomugqa omuhle, ukuthembeka okuphezulu, izindleko eziphansi kanye nokukhiqizwa okuzenzakalelayo okuqhubekayo.

Ngawo-1980, ibhodi eliphrintiwe elingaphezulu (SMT) langena kancane kancane esikhundleni se-plug-in ye-plug futhi laba yinto ejwayelekile yokukhiqiza.

Kusukela ngama-1990s, ukufakwa komhlaba kuye kwaqhubeka kusuka kusakhiwo sephakethe (i-QFP) kuya kwiphakeji yamalungu afanayo eyisiyingi (BGA).

Kusukela ekuqaleni kwekhulu lama-21, i-high-density BGA, i-chip level package kanye ne-multi-chip module yokupakisha ibhodi ephrintiwe ngokusekelwe ezintweni eziphilayo ze-laminate athuthuke ngokushesha.

Umlando we-PCB eChina

Ngo-1956, iChina yaqala ukuthuthukisa i-PCB.

Ngawo-1960, ukukhiqizwa kweqoqo lephaneli elilodwa, ukukhiqizwa okuncane kweqoqo lesikole esinamacala amabili kwaqala ukuthuthukisa ibhodi le-multilayer.

Ngawo-1970, ngenxa yemikhawulo yezimo zomlando ngaleso sikhathi, ukuthuthuka okuhamba kancane kobuchwepheshe be-PCB kwenza bonke ubuchwepheshe bokukhiqiza busalele emuva ezingeni eliphambili langaphandle.

Ngawo-1980, imigqa esezingeni eliphakeme yokukhiqiza yohlangothi olulodwa, ohlangothini oluphindwe kabili nebhodi eliphrintiwe elinemigqa eminingi yethulwa ivela phesheya, okwathuthukisa izinga lobuchwepheshe bokukhiqiza bebhodi eliphrintiwe eChina

Ngawo-1990, abakhiqizi be-PCB bakwamanye amazwe abavela eHong Kong, eTaiwan naseJapan beza eChina ukuzokwakha amabhizinisi ahlanganyelwe kanye nezimboni eziphethwe ngokuphelele, okwenza ukukhishwa kwe-PCB nobuchwepheshe baseChina kuthuthuke ngokushesha.

Ngo-2002, yaba ngumkhiqizi we-PCB wesithathu ngobukhulu.

Ngo-2003, inani lokukhipha nokungenisa nokuthekelisa ivolumu ye-PCB kweqe thina u- $ 6 billion, lidlula i-United States okokuqala futhi laba ngumkhiqizi we-PCB wesibili ngobukhulu emhlabeni. Inani lokukhiphayo nalo lenyuke lisuka ku-8.54% ngo-2000 laya ku-15.30%, cishe liphindwe kabili.

Ngo-2006, iChina yadlula iJapane njengomkhiqizi omkhulu kunayo yonke we-PCB ngenani lokukhipha kanye nezwe elisebenza kakhulu kwezobuchwepheshe.

Eminyakeni yamuva nje, China PCB igcine izinga lokukhula elicishe libe ngu-20%, eliphakeme kakhulu kunezinga lokukhula kwemboni ye-PCB yomhlaba!
