Ukwanda kokungena kwe-5G kanye ne-automotive electronics kuzoletha umfutho wokukhula kwesikhathi eside embonini ye-PCB, kodwa ngaphansi kwethonya lobhubhane lwango-2020, isidingo sama-electronics abathengi nama-PCB ezimoto sisazokwehla, kanye nesidingo sama-PCB kwezokuxhumana ze-5G kanye imikhakha yezokwelapha kulindeleke ukuthi ikhule kakhulu.
Izinhlelo zokusebenza ze-PCB ezansi nomfula zihlakazekile, futhi isidingo emikhakheni ehlukahlukene siyahlukahluka. Ngo-2019, ngaphandle kwesidingo sezicelo zengqalasizinda ezifana namanethiwekhi nokugcinwa, okuqhubeka nokukhula, ezinye izingxenye zehlile. Emkhakheni we-elekthronikhi yabathengi, inani eliphumayo emhlabeni wonke ngo-2019 lehle ngo-2.8% unyaka nonyaka, inani eliphumayo emhlabeni wonke emkhakheni wezogesi wezimoto lehle ngaphezu kuka-5%, kanti indawo yokulawulwa kwezimboni i-aerospace nezinkundla zezokwelapha zehla kancane. . Kulindeleke ukuthi ngo-2020, ngaphezu kwezinto zikagesi zezokwelapha, izinguquko ezidingekayo kweminye imikhakha emincane zizoqhubeka nokuthambekela konyaka odlule. Ngo-2020, inkambu ye-electronics yezokwelapha izogqugquzelwa yilolu bhubhane, futhi isidingo se-PCB sizokhula kakhulu, kodwa ingxenye yayo encane izoba nokukhushulwa okulinganiselwe esidingweni sisonke.
Kulinganiselwa ukuthi isidingo sama-electronics abathengi afana nomakhalekhukhwini nama-PC, lapho ama-PCB azobala cishe ama-60% wezinhlelo zokusebenza ezansi ngo-2020, sizoncipha cishe ngo-10%. Ukwehla kokuthunyelwa kwamaselula emhlabeni wonke kuye kwancipha ngo-2019, futhi ukuthunyelwa kwe-PC namathebulethi kuye kwaphindeka kancane; phakathi nenkathi efanayo, inani lokukhiphayo le-PCB yaseChina emikhakheni engenhla laba ngaphezu kuka-70% wengqikithi yomhlaba. . Ngekota yokuqala ka-2020, ngenxa yomthelela walolu bhubhane, ukuthunyelwa komhlaba wonke kwemikhiqizo kagesi yabathengi efana nomakhalekhukhwini, ama-PC, namaphilisi kwehle kakhulu; uma ubhubhane lomhlaba wonke lungalawuleka ngekota yesibili, ukwehla kwesidingo setheminali ye-elekthronikhi yabathengi kulindeleke ukuba sinciphe ngekota yesithathu, okungokwesiko ngekota yesine Isizini yokusetshenziswa okuphezulu ilethe ukukhula okuyisinxephezelo, kodwa kulindeleke ukuthi ukuthunyelwa unyaka wonke usazokwehla kakhulu unyaka nonyaka. Ngakolunye uhlangothi, ukusetshenziswa kwe-FPC kanye ne-HDI ephezulu ngefoni eyodwa yeselula ye-5G kuphakeme kunamaselula e-4G. Ukwenyuka kwezinga lokungena kwezingcingo eziphathwayo ze-5G kunganciphisa ukuncipha kwesidingo okubangelwa ukwehla kokuthunyelwa komakhalekhukhwini ngezinga elithile. Ngaso leso sikhathi, imfundo eku-inthanethi, Isidingo samahhovisi aku-inthanethi se-PC siphinde savela kancane, futhi ukuthunyelwa kwe-PC kuye kwancipha uma kuqhathaniswa nokunye ukuthunyelwa kwamakhompiyutha kanye nezinto zikagesi zabathengi. Eminyakeni elandelayo ye-1-2, ingqalasizinda yenethiwekhi ye-5G isesikhathini sokwakha, futhi izinga lokungena kwamaselula we-5G aliphezulu. Esikhathini esifushane, isidingo se-FPC kanye ne-HDI ephezulu eqhutshwa omakhalekhukhwini be-5G silinganiselwe, futhi umthamo omkhulu ungase ubonakale kancane kancane eminyakeni engu-3-5 ezayo.
