PCB wesifunda ibhodi uyinki ngokuvamile uhlukaniswe ngezinhlobo ezintathu, ngokulandelana, i-PCB umugqa wokufaka inki, inki yokushisela nombhalo uyinki. Amanye angama-carbon oil conductive (abuye abizwe ngokuthi yi-conductive carbon ink), uwoyela we-conductive silver (obizwa nangokuthi i-conductive silver paste), izinhlobo ezimbili zokugcina zomthamo ojwayelekile zincane.

I-PCB ifensinitive etching ink

Okokuqala, uyinki wokugcwala we-PCB line. Izinto eziyisisekelo zebhodi le-PCB yipuleti egqoke ithusi, futhi kukhona ungqimba lwe-foil yethusi kuyo. Kudinga uyinki wokuthwebula obucayi ekuphrintweni kwesikrini, bese ilashwa ngokuthuthuka kokuchayeka, isuse indawo engachazwanga, bese iyinki. Lo mugqa wokufaka inki, ikakhulukazi wokuvikela, wokufaka umugqa omuhle, ngemuva kokusetshenziswa kwesisombululo se-sodium hydroxide aqueous ukususa uyinki. Iningi lebhokisi lesifunda lokufaka inkino lihlaza okwesibhakabhaka, ngakho-ke libizwa nangokuthi uwoyela womugqa oluhlaza okwesibhakabhaka noma uwoyela ozwelayo ohlaza okwesibhakabhaka, amanye ama-hardware insimbi engagqwali nawo azosebenzisa leyinki, abantu ngabanye bazoyibiza ngokuthi i-glue ezwelayo, empeleni, ihluke kakhulu ipuleti lokuphrinta ngeglu ebucayi.

Amabili, i-PCB Welding ink

Uhlobo lwesibili lukayinki ukugxila kulokho, okungukuthi, i-PCB wesifunda webhodi lokushisela inki, owaziwa nangokuthi uyinki wokushisela. Uyinki weSolder uyibhodi ejwayelekile kakhulu le-PCB ukusetshenziswa okuyinki okuyinhloko. Isendlalelo sepende eluhlaza esilibonayo ebhodini lesifunda empeleni iyinki yokuvimba i-solder.

Ngokuya ngemodi ephulukisayo, inki ye-solder inoyinki okhulayo wezithombe, ukushisa okuphulukisa ukusetha inki, nokukhanya kwe-UV kuphulukisa inki ye-UV. Futhi ngokuhlukaniswa kwepuleti, ne-PCB ipuleti lokushisela ipuleti eliqinile, uyinki wokufaka insimbi othambile we-FPC, ne-inki ye-aluminium yokufaka inki, i-aluminium ipeni inki nayo ingasetshenziswa kupuleti le-ceramic.

Uyinki we-soldensensitive ulapha ukukhanya kwe-UV, ukuphrinta kwesikrini, kudingeka ukuthi ubhake ngaphambi kokuvezwa kokuvezwa. Ngokuvamile kusetshenziselwa ukwenza zonke izinhlobo zebhodi eliqinile le-PCB, ibhodi elithambile elinebhodi lesifunda elicwengekile ngaphezu kwefilimu eyomile lizosebenzisa no-inki we-solder obucayi. Futhi i-thermosetting ink, iphrintwa ngqo ngemuva kokubhaka. Okujwayelekile kuyinki yebhodi le-antenna yefoni ephathekayo, uyinki wokukhanyisa omhlophe oyinki omhlophe wokushisela. Uyinki we-UV, uwoyela oluhlaza we-UV uvame kakhulu, izidingo ezijwayelekile akuzona amabhodi wesifunda aphakeme kakhulu noma ukukhishwa okukhulu kwamabhodi wesifunda wokukhiqiza okuzenzakalelayo kuzosetshenziswa. Uyinki we-UV, uyinki we-photosensitive, u-inki we-thermosetting ohluke kathathu, izidingo zikayinki we-photosensitive ziphakeme kakhulu, zilandelwa uyinki we-thermosetting, bese i-UV ink, ngokuvamile, ukunamathela kwe-inki ye-UV kuzoba kubi, ukucacisa inki ye-photosensitive kuphakeme.

Okwesithathu, uyinki wombhalo we-PCB

Uhlobo lwesithathu lukayinki ngumbhalo wombhalo, uyinki wombhalo ekunyathelisweni kwebhodi lesifunda, ikakhulukazi ukuphrinta izinhlamvu namamaki. Uyinki ovamile womlingiswa umhlophe futhi umnyama, umhlophe usetshenziswa kakhulu, cishe lonke ibhodi lesifunda ngaphezu koqweqwe olumhlophe lwe-solder luphrintwa ngoyinki wombhalo omhlophe. I-Aluminium substrate, ibhodi le-strip strip, ilambu langemuva, njll., Ngenxa yokusetshenziswa kukayinki omhlophe omhlophe, ngakho-ke izinhlamvu ezingenhla zisebenzisa inki yombhalo omnyama.

Abakhiqizi bebhodi lesifunda ngalinye ngenxa yezidingo zamakhasimende, bazosebenzisa uyinki ophuzi noma omunye umbala, kepha ngenxa yebhodi lesifunda elibhala isilinganiso sikayinki sincane kakhulu, abakhiqizi abaningi bakayinki abazimisele ngokuya ekukhiqizeni, ngakho-ke umbhalo uzo funa uyinki okhethekile wombala kunzima kakhulu ukuthola, ncoma ukuthi uyinki wokushisela ukwenza ubufakazi, isici kuyinki yokushisela lapho kusetshenziswa inki yokubhala, Kuzoba nomkhuba wokulahleka kukawoyela.

Uyinki wombhalo ikakhulukazi uyinki yombhalo we-thermosetting, abanye bazosebenzisa uyinki wombhalo ophulukisa nge-UV. Iningi labakhiqizi bakayinki likhiqize inki yombhalo omhlophe we-UV, njengeKawashima UVM-5 iyi-UV elapha uwoyela omhlophe.

Ukukhiqizwa kwebhodi lesifunda se-PCB kusetshenziswa kakhulu kulezi zinhlobo ezintathu zikayinki ezingenhla, ngakho-ke yiziphi izindima zalezi zinhlobo ezintathu zikayinki?

Uyinki wokufotwa wezithombe usetshenziselwa ikakhulukazi ukuvikela ucwecwe lwethusi ebhodini lesifunda elingadingi ukuqoshwa. Inomphumela wokumelana nokuchaphazeleka, ukumelana ne-asidi ne-alkali nokumelana ne-electroplating.

Okubili, uyinki wokushisela ubuye usetshenziswe njengendima yokuvikela, ukwahlukanisa, ukumelana kabusha, ukumelana negolide, igolide, ithini, isiliva kanye nosawoti. Ingavikela nesifunda se-foil wesifunda ebhodini lesifunda ekusetshenzisweni kwesikhathi esizayo futhi yenyuse impilo yebhodi lesifunda.

Okwesithathu, iqhaza likayinki wombhalo ngokuqhathaniswa nambili edlule, indima ayinkulu kakhulu, ikakhulukazi njengomlingiswa wophawu noma imidwebo ongayisebenzisa.
