Ibhodi yesekethe PCB I-inki yahlulwe yaziindidi ezintathu, ngokwahlukeneyo, i-PCB yokufaka inki, inki ye-welding kunye ne-inki yokubhaliweyo. Ezinye zi-conductive i-oyile ye-khabhoni (ekwabizwa ngokuba yi-inki ye-khabhoni), i-oyile yesilive (ekwabizwa ngokuba kukuncamathela kwesilivere), ezi ntlobo zimbini zokugqibela zedosi ziphantsi.

I-PCB yefensile ebonakalayo

Okokuqala, i-inki enezinto emgceni PCB. Izinto ezisisiseko zebhodi ye-PCB yiplati enxibe ubhedu, kwaye kukho umaleko wefoyile yobhedu kuyo. Ifuna i-inki ebuthathaka yoshicilelo lwesikrini, emva koko inyange ngokuphuhliswa kokuvezwa, imise indawo engachazwanga, ize emva koko inyuswe. Lo mgca wokutsala i-inki, ikakhulu ukukhusela, ukutsala umgca olungileyo, ngasemva kokusetyenziswa kwesisombululo se-sodium hydroxide esisusa i-inki. Uninzi lwebhodi yesekethe etching inki iluhlaza okwesibhakabhaka, ke ikwabizwa ngokuba ngumgca weoyile eluhlaza okwesibhakabhaka okanye ioyile ebuthathaka eluhlaza, ezinye izixhobo zentsimbi ezingenazintsimbi ziya kusebenzisa le inki, umntu ngamnye uya kuyibiza njengeglu ethe tye, enyanisweni, yahluke kakhulu ipleyiti yokushicilela eneglu ethe-ethe.

Ezimbini, i-PCB ye-inki yokufaka

Uhlobo lwesibini lwe-inki kukugxila kuyo, oko kukuthi, ibhodi ye-PCB yebhodi ye-welding ink, ekwabizwa ngokuba yi-inki ye-welding. I-inki ye-Solder yibhodi ye-PCB eqhelekileyo lolona phawu lusetyenziswayo. Umaleko wepeyinti eluhlaza esiyibonayo kwibhodi yesekethe eneneni yi-solder ethintela i-inki.

Ngokwendlela yokuphilisa, i-inki ye-solder ine-inki ekhulayo yokufota, ukuphilisa ubushushu bokubeka inki, kunye nokukhanya kwe-UV ukuphilisa inki ye-UV. Kwaye ngokokuhlelwa kweplate, kunye ne-PCB ye-inki ye-hard welding inki, i-inki ye-FPC ye-inki yokuthambisa i-inki, kunye ne-aluminium ye-inki ye-welding inki, i-inki ye-aluminium ye-ink ingasetyenziselwa kwiplani ye-ceramic.

I-inki ye-photosensitive ye-solder kukuphilisa ukukhanya kwe-UV, ukushicilelwa kwescreen, kufuneka ubhake kwangaphambili emva kokuphuhliswa. Ngokubanzi isetyenziselwa ukwenza zonke iintlobo zebhodi enzima ye-PCB, ibhodi ethambileyo kunye nebhodi yesekethe yokuchaneka ngokuchanekileyo ukongeza kwifilimu eyomileyo iya kusebenzisa i-ink ye-solder enovakalelo. Kwaye i-inki ye-thermosetting, ishicilelwa ngqo emva kokubhaka. Okuqhelekileyo yinki yebhodi ye-eriyali yefowuni ephathekayo, ibhodi yokulayita ukukhanya inki emhlophe yokunyathela. I-inki ye-UV, ioyile eluhlaza ye-UV ixhaphake kakhulu, iimfuno ngokubanzi azizibhodi zesekethe ziphakamileyo okanye imveliso enkulu yeebhodi zesekethe zemveliso ezizenzekelayo ziya kusetyenziswa. I-inki ye-UV, i-inki ye-photosensitive, i-inki ye-thermosetting kathathu, iimfuno ze-inki ye-photosensitive ziphezulu kakhulu, zilandelwa yinki ye-thermosetting, emva koko i-inki ye-UV, ngokuthetha ngokubanzi, ukubambelela kwe-inki ye-UV kuya kuba kubi, ukuchaneka kwe-inki ye-photosensitive kuphezulu.

Isithathu, i-inki yombhalo we-PCB

Uhlobo lwesithathu lwe-inki ngumbhalo obhaliweyo, i-inki yokubhaliweyo kushicilelo lwebhodi yesekethe, ikakhulu ukuprinta abalinganiswa kunye namanqaku. Inki yomlinganiswa oqhelekileyo imhlophe kwaye imnyama, emhlophe isetyenziswa ngakumbi, phantse yonke ibhodi yesekethe ukongeza kumaleko omhlophe we-solder aprintwe nge-inki yombhalo omhlophe. I-Aluminium substrate, ibhodi yomtya wesibane, ilayithi, njl.

Abavelisi bebhodi yesekethe nganye ngenxa yeemfuno zabathengi, baya kusebenzisa i-inki etyheli okanye enye, kodwa ngenxa yebhodi yesekethe yokubhala i-inki yedosi incinci kakhulu, uninzi lwabenzi be-inki abazimisele ukuya kwimveliso, ke isicatshulwa ufuna umbala okhethekileyo weinki kunzima kakhulu ukufumana, ukucebisa i-inki yokwenza i-inki ukwenza ubungqina, isiphene kuku-inki ye-welding xa kusetyenziswa i-inki, Kuya kubakho into ilahleko oyile.

I-inki yokubhaliweyo ubukhulu becala yi-thermosetting inki yokubhaliweyo, abanye baya kusebenzisa i-UV ephilisa i-inki yokubhaliweyo. Uninzi lwabavelisi be-inki bavelise i-inki emhlophe ye-UV, efana neKawashima UVM-5 yinyani yeoyile emhlophe ephilisa i-UV.

Imveliso yebhodi yesekethe ye-PCB isetyenziswa ikakhulu kwezi ntlobo zintathu ze-inki, ke zithini iindima zolu hlobo lwe-inki?

I-inki yokufotwa kweefoto isetyenziselwa ukukhusela ifoyile yobhedu kwibhodi yesekethe engafunekiyo. Inesiphumo sokumelana nokuchaphazeleka, i-asidi kunye ne-alkali ukumelana nokuchasana kwe-electroplating.

Okwesibini, i-inki ye-welding ikwasetyenziswa njengendima yokukhusela, ukugquma, ukunganyangeki kwakhona, ukumelana negolide, igolide, itoti, isilivere kunye netyuwa. Inokukhusela isiphaluka sobhedu kwibhodi yesekethe kusetyenziso lwexesha elizayo kwaye yonyuse ubomi bebhodi yesekethe.

Isithathu, indima ye-inki yokubhaliweyo xa kuthelekiswa nezo zimbini zangaphambili, indima ayinkulu kakhulu, ikakhulu njengophawu lomlinganiswa okanye iigrafiki zokuzisebenzisa.
