Ukufafaza ngothayela kuyisinyathelo nenqubo kunqubo yokuhlola ye-PCB.
Ukufafaza ngothayela kuyisinyathelo nenqubo kunqubo yokuhlola ye-PCB.Ibhodi le-PCB licwiliswa echibini le-solder elincibilikisiwe, ukuze zonke izindawo zethusi eziveziwe zimbozwe nge-solder, bese i-solder eyeqile ebhodini isuswa yi-hot air cutter.susa.Amandla e-solder nokuthembeka...Funda kabanzi -
I-PCB CNC
I-CNC eyaziwa nangokuthi i-computer routing, i-CNCCH noma ithuluzi lomshini we-NC empeleni yi-HongKong kunegama, yabe yethulwa e-China, i-pearl river delta ingumshini wokugaya we-CNC, kanti kwenye indawo izobizwa ngokuthi "isikhungo somshini we-CNC" uhlobo oluthile lomshini. ukucubungula, kuyinqubo entsha...Funda kabanzi -
Izinto ezidinga ukunakwa ekwakhiweni kwe-PCB
1. Injongo ye-PCB design kufanele icace.Ngemigqa yesignali ebalulekile, ubude bezintambo kanye nokucubungula amalophu aphansi kufanele buqine kakhulu.Ngemigqa yesignali enesivinini esiphansi futhi engabalulekile, ingabekwa endaweni ebaluleke kakhulu ephansi yezintambo..Izingxenye ezibalulekile zihlanganisa: ukuhlukaniswa kwamandla kagesi;...Funda kabanzi -
PCB inqubo onqenqemeni
Unqenqema lwenqubo ye-PCB luwunqenqema olude lwebhodi olungenalutho olusethelwe indawo yokudlulisela ithrekhi nokubekwa kwamaphoyinti omaka ngesikhathi sokucubungula i-SMT.Ububanzi bonqenqema lwenqubo ngokuvamile buba ngu-5-8mm.Enqubweni yokuklama ye-PCB, ngenxa yezizathu ezithile, ibanga phakathi komphetho we-compo...Funda kabanzi -
I-Global and China Automotive PCB (Amabhodi Esifunda Aphrintiwe) Ukubuyekezwa Kwemakethe
Ucwaningo lwe-PCB yezimoto: ubuhlakani bezimoto kanye nokufakwa kukagesi kuletha isidingo sama-PCB, futhi abakhiqizi bendawo bayagqama.Umqedazwe we-COVID-19 ngo-2020 wehlise ukuthengiswa kwezimoto emhlabeni wonke futhi kwaholela ekwehleni okukhulu kwesikali semboni safinyelela ku-USD6,261 wezigidi.Nokho ubhubhane kancane kancane luhambisana...Funda kabanzi -
Ukuchayeka
Ukuchayeka kusho ukuthi ngaphansi kwemisebe yokukhanya kwe-ultraviolet, i-photoinitiator imunca amandla okukhanya bese ibola ibe ama-radicals mahhala, bese ama-free radicals aqalise i-photopolymerization monomer ukwenza ukusabela kwe-polymerization kanye nokuxhumanisa.Ukuchayeka kuvame ukuthwala...Funda kabanzi -
Buyini ubudlelwano phakathi kwezintambo ze-PCB, ngembobo namandla okuthwala amanje?
Ukuxhumana kukagesi phakathi kwezingxenye ku-PCBA kufinyelelwa ngocingo lwe-foil yethusi kanye nezimbobo kusendlalelo ngasinye.Ukuxhumana kukagesi phakathi kwezingxenye ku-PCBA kufinyelelwa ngocingo lwe-foil yethusi kanye nezimbobo kusendlalelo ngasinye.Ngenxa yemikhiqizo ehlukene...Funda kabanzi -
Ukwethulwa komsebenzi wesendlalelo ngasinye sebhodi lesifunda le-PCB elinezingqimba eziningi
Amabhodi wesekethe we-multilayer aqukethe izinhlobo eziningi zezendlalelo zokusebenza, njengalezi: isendlalelo esivikelayo, isendlalelo sesikrini sikasilika, isendlalelo sesignali, isendlalelo sangaphakathi, njll. Kungakanani okwaziyo ngalezi zendlalelo?Imisebenzi yesendlalelo ngasinye ihlukile, ake sibheke ukuthi iyiphi imisebenzi yezinga ngalinye ...Funda kabanzi -
Isingeniso kanye nezinzuzo kanye nokubi kwebhodi le-ceramic PCB
1. Kungani usebenzise amabhodi esifunda se-ceramic I-PCB evamile ngokuvamile yenziwe nge-foil yethusi kanye ne-substrate bonding, futhi i-substrate material ikakhulukazi i-glass fiber (FR-4), i-phenolic resin (FR-3) nezinye izinto, i-adhesive ngokuvamile i-phenolic, i-epoxy. , njll.

I-infrared + i-hot air reflow soldering
Maphakathi nawo-1990s, kwakunomkhuba wokudlulisela ekushisiseni kwe-infrared + hot air ekufakweni kwe-reflow soldering e-Japan.Ishisisa ngama-30% emisebe ye-infrared kanye no-70% womoya oshisayo njengesithwali sokushisa.I-ovini ye-infrared hot reflow oven ihlanganisa ngempumelelo izinzuzo zokugeleza kabusha kwe-infrared kanye ne-convection ephoqelelwe yomoya oshisayo ...Funda kabanzi -
Iyini i-PCBA processing?
Ukucutshungulwa kwe-PCBA kuwumkhiqizo oqediwe webhodi elingenalutho le-PCB ngemva kwesichibi se-SMT, ipulaki ye-DIP kanye nokuhlolwa kwe-PCBA, ukuhlolwa kwekhwalithi nenqubo yokuhlanganisa, okubizwa ngokuthi i-PCBA.Iqembu eliphathisayo iletha iphrojekthi yokucubungula efekthri yokucubungula ye-PCBA, bese ilinda umkhiqizo oqediwe...Funda kabanzi -
Etching
Inqubo yokuqopha ibhodi le-PCB, esebenzisa izinqubo zokuhlanganisa amakhemikhali zendabuko ukugqwala izindawo ezingavikelekile.Kufana nokumba umsele, indlela esebenzayo kodwa engasebenzi kahle.Enqubweni ye-etching, iphinde ihlukaniswe ibe inqubo yefilimu enhle kanye nenqubo yefilimu engalungile.Inqubo yefilimu enhle...Funda kabanzi
