Ukungena ngaphezulu kwe-5g ne-alethronive electronic kuzoletha umfutho wokukhula kwesikhathi eside embonini ye-PCB, kepha ngaphansi kwethonya lesifo sowesilisa esingu-2020, isidingo se-PCBS sezokuxhumana kanye nezinto zezokwelapha kulindeleke ukuthi zikhule kakhulu.
Izicelo ze-PCB Downstream zihlakazekile, futhi ukufunwa emikhakheni ehlukahlukene kuyahlukahluka. Ngo-2019, ngaphandle kwesidingo sezicelo zengqalasizinda ezifana nezokuxhumana nesitoreji, eziqhubeka zikhula, ezinye izingxenye zinqabile. Emkhakheni we-elekthronikhi yabathengi, inani lokuphuma komhlaba ngo-2019 sehle ngo-2.8% unyaka nonyaka, inani lokuphuma komhlaba emkhakheni wezimoto ze-aircononics lawela ngaphezulu kwama-5%, kanti izinkundla zokulawula zezimboni zinciphile kancane. Kulindeleke ukuthi ngo-2020, ngaphezu kwama-elekthronikhi wezokwelapha, izinguquko zesidingo kwamanye ama-sub-sors zizoqhubeka nonyaka owedlule. Ngo-2020, insimu yezokwelapha yezokwelapha izovuswa ubhubhane, futhi isidingo se-PCB sizokhulisa kakhulu, kepha ingxenye yaso encane izoba nokukhulisa okulinganiselwe kwisidingo sonke.
Kulinganiselwa ukuthi isidingo se-elekthronikhi yabathengi njengamafoni amaselula nama-PC, lapho ama-PCB azowaphendula cishe ama-60% ezicelo ezaphansi ngo-2020, zizoncipha cishe ngo-10%. Ukwehla kokuthunyelwa kwefoni ye-Global Mobile kunciphise ngo-2019, futhi ukuthunyelwa kwe-PC kanye nokuhanjiswa kwethebhulethi kuphinde kwakhiwe kancane; Ngesikhathi esifanayo, inani lokukhipha le-PCB laseChina kulezi zinkambu ezingenhla libalwa ngaphezulu kwama-70% omhlaba wonke. . Ekota yokuqala ka-2020, ngenxa yomthelela wobhubhane, imikhiqizo yomhlaba wonke yemikhiqizo ye-elekthronikhi yabathengi efana nezingcingo, ama-PC kanye namathebulethi awela kakhulu; Uma ubhubhane lomhlaba wonke lungalawulwa kwikota yesibili, ukwehla kwesibalo se-elekthronikhi somsebenzi we-global Consumer Electronic kulindeleke ukuthi kunciphise ikota yesithathu, kepha kulindeleke ukuthi ukuthunyelwa unyaka wonke kuzoqhubeka unyaka nonyaka. Ngakolunye uhlangothi, ukusetshenziswa kwe-FPC ne-High-End HDI ngefoni eyodwa ye-5G ephathekayo ephakeme kunaleyo ngomakhalekhukhwini we-4G. Ukwanda kwezinga lokungena kwezingcingo ze-5G mobile kunganciphisa ukufunwa kwe-shrinkage okubangelwa ukwehla okubangelwa ukuhanjiswa kwefoni okuphelele. Ngasikhathi sinye, imfundo ye-inthanethi, isidingo sehhovisi le-inthanethi se-PC senziwe kabusha ngokwengxenye, futhi ukuthunyelwa kwe-PC kuncishisiwe uma kuqhathaniswa nokuhanjiswa ngogesi kwekhompyutha kanye nabathengi. Eminyakeni engu-1-2 elandelayo, ingqalasizinda yenethiwekhi ye-5G isesesikhathini sokwakha, kanye nezinga lokungena kwezingcingo ze-5G. Esikhathini esifushane, isidingo se-FPC kanye ne-HDI ephezulu-end HDI eqhutshwa ngezingcingo ezi-5G zilinganiselwe, futhi ivolumu enkulu ingabonakala kancane kancane eminyakeni engu-3-5 elandelayo.
