[VW PCBworld] Iibhodi zesekethe eziprintiweyo zezona ndawo zibalulekileyo zonxibelelwano lwe-elektroniki kwiimveliso zombane, kwaye zaziwa “njengomama weemveliso zombane”.Umzantsi weebhodi zesekethe eziprintiweyo zisasazwa ngokubanzi, zigubungela izixhobo zonxibelelwano, iikhompyuter kunye neeperipherals, i-electronics yabathengi, ulawulo lwamashishini, unyango, i-elektroniki yemoto, umkhosi, iteknoloji ye-aerospace kunye nezinye iinkalo.Ukungafumaneki indawo kukuba ishishini lokuvelisa ibhodi yesekethe eprintiweyo linokuhlala liphuhlisa ngokuthe chu Enye yezinto.Kutsha nje lokutshintshela ishishini lePCB, iJiangxi iya kuba yenye yezona ziseko zikhulu zemveliso.
Ukuphuhliswa kweebhodi zeesekethe eziprintiweyo zaseChina zivela ngasemva, kwaye ulungelelwaniso lwabavelisi belizwe lutshintshile
Ngowe-1956, ilizwe lam laqalisa ukwenza iibhodi zesiphaluka ezishicilelweyo.Xa kuthelekiswa namazwe aphuhlileyo, ilizwe lam lisalela ngasemva phantse kumashumi amabini eminyaka ngaphambi kokuthatha inxaxheba nokungena kwimarike yePCB.Ingqikelelo yeesekethe eziprintiweyo yaqala ukuvela ehlabathini ngo-1936. Yathi yabekwa phambili ngugqirha waseBritani ogama linguEisler, kwaye waba nguvulindlela kwitekhnoloji ehambelanayo yeesekethe eziprintiweyo zefoil etching process.
Nangona kunjalo, kwiminyaka yakutshanje, uqoqosho lwelizwe lam luphuhliswe ngokukhawuleza, ludibene nenkxaso yomgaqo-nkqubo we-high-tech, iibhodi zeesekethe eziprintiweyo zelizwe lam ziphuhliswe ngokukhawuleza kwindawo efanelekileyo.2006 ibingunyaka obalulekileyo kuphuhliso lwePCB yelizwe lam.Kulo nyaka, ilizwe lam lidlule ngempumelelo eJapan laze laba sesona siseko sikhulu semveliso yePCB emhlabeni.Ngokufika kwexesha lezorhwebo le-5G, abaqhubi abakhulu baya kutyala imali ngakumbi kulwakhiwo lwe-5G kwixesha elizayo, eliya kudlala indima enhle ekukhuthazeni ukuphuhliswa kweebhodi zeesekethe eziprintiweyo kwilizwe lam.
Ixesha elide, i-Pearl River Delta kunye ne-Yangtze River Delta zezona ndawo ziphambili zophuhliso lweshishini lasekhaya le-PCB, kwaye ixabiso lemveliso liye laba malunga ne-90% yexabiso elipheleleyo lemveliso yelizwe laseChina.Ngaphezulu kwe-1,000 iinkampani zasekhaya ze-PCB zisasazwa ikakhulu kwi-Pearl River Delta, i-Yangtze River Delta kunye ne-Bohai Rim.Oku kungenxa yokuba le mimandla ihlangabezana noxinzelelo oluphezulu lweshishini le-elektroniki, imfuno enkulu yamacandelo asisiseko, kunye neemeko ezilungileyo zokuhamba.Iimeko zamanzi nombane.
Nangona kunjalo, kwiminyaka yakutshanje, ishishini lasekhaya le-PCB lidluliselwe.Emva kweminyaka emininzi yokufuduka kunye nendaleko, imephu yoshishino lwebhodi yesekethe iye yafumana utshintsho olufihlakeleyo.I-Jiangxi, i-Hubei Huangshi, i-Anhui Guangde, kunye ne-Sichuan Suining ziye zaba ziziseko ezibalulekileyo zokudluliselwa kweshishini le-PCB.
Ngokukodwa, iPhondo laseJiangxi, njengesikhundla somda wokwenza ukuhanjiswa kwe-gradient yeshishini le-PCB kwi-Pearl River Delta kunye ne-Yangtze River Delta, litsale ibhetshi emva kwebhetshi yeenkampani ze-PCB ukuba zizinze kwaye zithathe iingcambu.Iye yaba "yindawo yedabi entsha" kubavelisi bePCB.

Isixhobo somlingo sokudluliselwa kweshishini le-PCB kwi-Jiangxi-ngumnini womvelisi omkhulu wobhedu waseTshayina kunye nomthengisi
Ukusukela ekuzalweni kwePCB, isantya sokufuduka kwamashishini asizange siyeke.Ngamandla ayo ayingqayizivele, i-Jiangxi ibe ngumnye wabalinganiswa ekuqhubeni ukuhanjiswa kweshishini lebhodi yesekethe e-China.Ukuthontelana kwezixa ezikhulu zeenkampani zePCB kwiPhondo laseJiangxi zixhamle kwiinzuzo zazo “kwiPCB” imathiriyeli ekrwada.
IJiangxi Copper ngoyena mvelisi nomthengisi wobhedu omkhulu waseTshayina, kwaye iphakathi kwabalishumi abaphezulu abavelisi bobhedu ehlabathini;kwaye esinye sezona ziseko zikhulu zobhedu eAsia ziseJiangxi, okwenza iJiangxi ibe nobutyebi bendalo bezinto zokuvelisa iPCB.Kwimveliso yePCB, yeyona nto ifunekayo ukucutha amaxabiso ezinto ezikrwada ukunciphisa iindleko zokwenziwa.
Ixabiso eliphambili le-PCB yokuvelisa ilele kwiindleko zezinto eziphathekayo, ezibalelwa malunga ne-50% -60%.Ixabiso lezinto eziphathekayo liyi-laminate ene-copper clad kunye ne-copper foil;kwi-laminate ye-copper clad, iindleko nazo zibangelwa yindleko yezinto eziphathekayo.Ibalelwa malunga ne-70%, ngakumbi ifoyile yobhedu, ilaphu lefibre yeglasi kunye neresin.
Kwiminyaka yakutshanje, ixabiso lezinto zePCB liyenyuka, nto leyo eye yabangela uxinzelelo kubakhiqizi abaninzi bePCB ukuba banyuse iindleko zabo;ke, iingenelo zePhondo leJiangxi kwizinto ezikrwada ziye zatsala iibhetshi zabavelisi bePCB ukuba bangene kwiipaki zayo zoshishino.
Ukongeza kwiingenelo zemathiriyeli ekrwada, iJiangxi inemigaqo-nkqubo yenkxaso ekhethekileyo yoshishino lwePCB.Iipaki zemizi-mveliso zixhasa amashishini ngokubanzi.Umzekelo, iGanzhou Economic and Technology Development Zone ixhasa amashishini amancinci naphakathi ukwakha ishishini kunye neziseko zokubonisa izinto ezintsha.Ngesiseko sokunandipha imigaqo-nkqubo yenkxaso ephezulu, banokunika umvuzo wexesha elinye ukuya kwi-300,000 yuan.Irhamncwa linokunika umvuzo we-5 yezigidi zeeyuan, kwaye linenkxaso elungileyo kwizaphulelo zemali, irhafu, iziqinisekiso zenkxaso-mali, kunye noncedo lwezemali.
Imimandla eyahlukeneyo ineenjongo ezahlukeneyo zokugqibela zophuhliso loshishino lwePCB.Indawo yoPhuhliso lwezoQoqosho lwaseLongnan, kwiNqila yaseWan'an, kwiNqila yaseXinfeng, njl. njl., ngamnye unobhukuqo lwakhe lokukhuthaza uphuhliso lwePCB.
Ukongeza kwimathiriyeli ekrwada kunye nezinto eziluncedo ngokwejografi, iJiangxi ikwanayo netyathanga leshishini lePCB elipheleleyo, ukusuka kwimveliso ephezulu yefoyile yobhedu, iibhola zobhedu, kunye nelaminates ezigqunywe ngobhedu ukuya kwizicelo ezisezantsi zePCB.Amandla e-PCB ye-Jiangxi enyukayo yomelele kakhulu.Abavelisi behlabathi abaphezulu abayi-6 belaminetha belaphu lentsimbi, iShengyi Technology, iNanya Plastics, iLianmao Electronics, iTaiguang Electronics, kunye neMatsushita Electric Works zonke zikwiJiangxi.Ngenzuzo eyomeleleyo yengingqi kunye nezibonelelo, iJiangxi kufuneka ibe lolona khetho lokuqala lokufuduswa kweziseko zemveliso yePCB kwizixeko eziselunxwemeni eziphuhliswe ngombane.
Amaza okudluliselwa kweshishini le-PCB lelinye lawona mathuba makhulu eJiangxi, ngakumbi ukudityaniswa kuphuhliso lolwakhiwo lweGuangdong-Hong Kong-Macao Greater Bay Area.Ishishini lolwazi lwe-elektroniki lishishini eliphambili elibalulekileyo, kwaye ishishini lebhodi yesekethe lelona khonkco libalulekileyo nelisisiseko kwikhonkco lolwazi lwe-elektroniki.
Ukususela kwithuba "lokudluliselwa", i-Jiangxi iya kuqinisa ukuphuculwa kobuchwepheshe kwaye ivule ngokupheleleyo indlela yokuphucula kunye nophuhliso lwe-PCB kummandla wayo.I-Jiangxi iya kuba yinyani "isiseko seposi" yokuhanjiswa kweshishini lolwazi lwe-elektroniki ukusuka eGuangdong, eZhejiang naseJiangsu.
