Ifilimu Eyomile Ye-PCB Idlala Kanjani Indima Ebalulekile Ekuthuthukiseni Ukwethembeka Kwe-PCB

Iyini i-PCB Dry Film?

Ifilimu eyomile iyinto ezwela ukukhanya esetshenziswa ekukhiqizweni kwama-PCB ukudala iphethini yesekethe. Ifakwa ebusweni be-laminate embozwe ngethusi bese ivezwa ekukhanyeni kwe-UV ngemaski yefilimu equkethe iphethini yesekethe. Ukukhanya kwe-UV kwelapha izindawo eziveziwe zefilimu eyomile, kuyenze iqine futhi kudale ungqimba oluvikelayo phezu kwezimpawu zethusi. Ngemva kokuvezwa, izindawo ezingavezwanga zefilimu eyomile ziyagezwa, kushiye iphethini yesekethe ebusweni bethusi. Ifilimu eyomile ivame ukusetshenziswa ekukhiqizweni kwe-PCB ngenxa yesisombululo sayo esiphezulu, ukunamathela okuhle ethusini, kanye nokulula kokucutshungulwa. Ake siqonde inqubo yokukhiqiza iphethini ye-PCB ndawonye:

Ukufihla Izimbobo Kufilimu Eyomile

Lapho uvala izimbobo kunqubo yefilimu eyomile, izici ezimbalwa kufanele zicatshangelwe ukuze kuqinisekiswe umphumela ophumelelayo:

• Yehlisa izinga lokushisa lefilimu nokucindezela ukuze ugweme ukulimala.
• Thuthukisa imbobo emangelengele kanye nethiphu ukuze unamathele kangcono.
• Khulisa amandla okuchayeka ukuze uthuthukise ukubambelela kwefilimu.
• Yehlisa ingcindezi ekhulayo ukuze kube nenqubo ebushelelezi.
• Gwema isikhathi eside phakathi kokufakwa kwefilimu nokuchayeka ukuze uvimbele ukusabalala kwefilimu.
• Qinisekisa ukuthi ifilimu eyomile isetshenziswa ngaphandle kokuqina ngokweqile ukuvimbela ukubola.

Ukungena ku-Dry Film Electroplating

Ukungena kwenzeka lapho isisombululo se-electroplating singena phakathi kwefilimu eyomile ne-foil yethusi, okubonisa ukunamathela okubi. Lolu daba lungadalwa yilokhu:

• Ukushisa kwefilimu okungalungile, okuphakeme kakhulu noma okuphansi kakhulu, okuthinta ukunamathela kwefilimu.
• Ukucindezela kwefilimu okungalungile, okuholela ezindaweni ezingalingani noma izikhala ezibeka engcupheni ukunamathela.
• Amandla okuchayeka anganele, okuholela ekwenziweni kwe-polymerization engaphelele kanye nokunamathela okubuthakathaka.
• Ukulawula okufanele phakathi nalezi zinqubo kubalulekile ukuvimbela amaphutha nokuqinisekisa ukuhlangana kwe-PCB kwekhwalithi ephezulu.

I-Surface Blister in PCB Production

Ukuqhuma kwamanzi kuyisici esivamile ekukhiqizeni i-PCB, okubangelwa izici ezihlukahlukene:

• Izinkinga zokucubungula i-substrate, njengokunganamatheli kahle phakathi kwe-copper foil ne-chemical copper.
• Ukungcola okuvela ezinqubweni zemishini noma olunye uketshezi, okuholela emazingeni kawoyela.
• Ukucindezela okwedlulele ngesikhathi se-copper brush plating, okubangela ukubola kanye namabhamuza alandelayo.
• Izinkinga zokugeza amanzi, okuhlanganisa ukungcoliswa okuphambene nokuphathwa kabi kwendawo yebhodi.
• Izinkinga ze-micro etching ekwelashweni kwangaphambili, okuholela ekuvuzeni okuyisisekelo kanye namabhamuza.
• Umsebenzi oqinile wesixazululo semvula yethusi, okuholela ekubambeni kabi kokunamathela.
• I-oxidation yendawo yebhodi ngesikhathi sokukhiqiza.
• Ukusebenza kabusha okungalungile kwethusi, okubangela amabhamuza ngenxa yezindlela ezingalungile noma ukulawula okunganele.
• Ukugeza amanzi anganele ngemuva kokuthuthukiswa noma ukungcoliswa kothuli endaweni yokusebenzela.
• Ukwehluleka ukumiselela amathangi okukha, okuholela ekuhlanzekeni nasezindabeni zokuqina kwendawo.
• Ukungcoliswa kwezinto eziphilayo, ikakhulukazi ukungcoliswa kukawoyela, emathangeni e-electroplating.
• Ukushaja amabhodi e-PCB angena emathangeni, ikakhulukazi lawo anomoya onyakaza, kufanele alawulwe ngokucophelela ukuze kuvinjelwe ukukhubazeka.

Ngokuqonda lezi zinselele nokusebenzisa izilawuli ezifanele, abakhiqizi be-PCB bangathuthukisa ikhwalithi nokuthembeka kwemikhiqizo yabo, bahlangabezane nezidingo ezidingekayo zezinto zikagesi zesimanje.

Shintsha ukukhiqizwa kwe-PCB yakho ngobuchwepheshe bethu befilimu eyomile ye-PCB! Ifilimu yethu ye-photosensitive iqinisekisa ukunemba nokusebenza kahle ekudluliseni amaphethini wesekethe izendlalelo zethusi, iqinisekisa ikhwalithi ephezulu, ama-PCB ayinkimbinkimbi. Valelisa ezindleleni zendabuko futhi wamukele ikusasa lokukhiqizwa kwe-PCB ngezixazululo zethu zefilimu eyomile ye-PCB!

Uma lesi sidingo sithinta ukutholakala noma ukukhishwa komkhiqizo, siqhathanise nenqubo yokuqinisekisa ikhwalithi ye-PCB kanye nokubuyekezwa kokulawula ukuvinjelwa ngaphambi kokuthumela amafayela okugcina ukuze abuyekezwe.
