Nokuba umgangatho we PCB i-inki igqwesile, ngokomgaqo, akunakwenzeka ukuba uhlukane nokudityaniswa kwezi nxalenye zingentla. Umgangatho obalaseleyo we-inki yimbonakaliso ebanzi yenzululwazi, ukuqhubela phambili kunye nokukhuselwa kokusingqongileyo kwifomula. Ibonakaliswa kwi:

I-Viscosity sisishunqulelo se-viscosity eguqukayo. Ngokuqhelekileyo ibonakaliswa yi-viscosity, oko kukuthi, uxinzelelo lwe-shear lokuhamba kwamanzi olwahlulwe yi-gradient yesantya kwicala le-flow layer, iyunithi yamazwe ngamazwe yi-Pa/sec (Pa.S) okanye i-milliPascal/sec (mPa.S). Kwimveliso PCB, ibhekisela fluidity inki eveliswa ngamandla angaphandle.

Ubudlelwane bokuguqulwa kweyunithi ye-viscosity:

1Pa. S=10P=1000mPa. S=1000CP=10dpa.s

I-Plastiki ithetha ukuba emva kokuba i-inki ikhubazeke ngamandla angaphandle, isagcina iimpawu zayo phambi kokuguqulwa. Iplastiki ye-inki inceda ekuphuculeni ukuchaneka kokushicilela;

I-inki ye-thixotropic (thixotropic) i-gelatinous xa imile, kwaye i-viscosity iyatshintsha xa iphathwa. Kwakhona kuthiwa yi-thixotropic kunye ne-anti-sagging;

I-Fluidity (inqanaba) Ubungakanani be-inki esasazeka phantsi kwesenzo samandla angaphandle. I-Fluidity yi-reciprocal of viscosity, kwaye i-fluidity inxulumene neplastiki kunye ne-thixotropy ye-inki. Iplastiki kunye ne-thixotropy inkulu, i-fluidity inkulu; i-fluidity inkulu, i-imprint kulula ukwandisa. Ubumanzi obuncinci, kulula ukubonakala ngenetha, okukhokelela kwisenzeko sokwenziwa kwe-inki, ekwabizwa ngokuba yiminatha;

I-Viscoelasticity ibhekiselele kwisakhono se-inki echetyiweyo kwaye yaphulwe emva kokuba i-inki ikhutshiwe yi-squeegee ukuba ibuyele ngokukhawuleza. Kuyimfuneko ukuba isantya inki deformation ngokukhawuleza kwaye inki rebounds ngokukhawuleza ukuba luncedo ekushicileleni;

Ukomisa kufuna ukuba i-inki yome kwisikrini ngokukhawuleza, kwaye kuthenjwa ukuba emva kokuba inki idluliselwe kwi-substrate, ngokukhawuleza kungcono;

Ubungakanani be-pigment ye-pigment kunye namasuntswana ezinto eziqinileyo, i-inki ye-PCB ingaphantsi kwe-10μm, kwaye ubungakanani be-fineness kufuneka bube ngaphantsi kwesinye esithathwini sokuvula umnatha;

Xa i-inki ye-inki isetyenziselwa ukuchola i-inki, iqondo apho i-inki ene-filamentous ingaqhawuki xa isoluliwe ibizwa ngokuba yi-stringiness. Intambo ye-inki inde, kwaye kukho imicu emininzi kumphezulu we-inki kunye nendawo yokushicilela, eyenza i-substrate kunye nepleyiti yokushicilela ibe mdaka kwaye ingakwazi nokushicilela;

Ukungafihli kunye nokufihla amandla kweinki

Kuba ii-inki zePCB, ngokweendlela ezahlukeneyo zokusetyenziswa kunye neemfuno, iimfuno ezahlukeneyo nazo zibekwe phambili elubala kunye nokufihla amandla e-inki. Ngokubanzi, ii-inks zesekethe, ii-inks eziqhubayo kunye nee-inki zabalinganiswa zonke zifuna amandla aphezulu okufihla. Ukumelana ne-solder kuguquguquka ngakumbi.

Ukumelana nemichiza ye-inki

Iinki zePCB zinemigangatho engqongqo yeasidi, ialkali, ityuwa kunye nezinyibilikisi ngokwenjongo yokusetyenziswa;

Ukuxhathisa komzimba nge-inki

I-inki ye-PCB kufuneka ihlangabezane nenkcaso yangaphandle yomkrwelo, ukuxhathisa ukothuka kwe-thermal, ukuxhathisa komatshini wamaxolo, kwaye ihlangabezane neemfuno ezahlukeneyo ezingqongqo zokusebenza kombane;

Ukhuseleko kunye nokukhuselwa kwendalo kwe-inki

Ii-inks zePCB ziyafuneka ukuba zibenetyhefu ephantsi, zinganuki, zikhuseleke kwaye zibe nobuhlobo nokusingqongileyo.

Ngaphezulu sishwankathele iipropathi ezisisiseko zee-inki zePCB ezilishumi elinambini. Phakathi kwabo, ekusebenzeni kwangempela kokuprintwa kwesikrini, ingxaki ye-viscosity ihambelana ngokusondeleyo nomsebenzisi. I-viscosity ibaluleke kakhulu ekugudimeni kwesikrini sesilika. Ngoko ke, kwi-PCB amaxwebhu obugcisa be-inki kunye neengxelo ze-QC, i-viscosity iphawulwe ngokucacileyo, ebonisa phantsi kweziphi iimeko kunye noluphi uhlobo lwesixhobo sokuvavanya i-viscosity.

Kweyona nkqubo yoshicilelo, ukuba i-viscosity ye-inki iphezulu kakhulu, kuya kuba nzima ukuyiprinta, kwaye imiphetho yemizobo iya kuba nzima kakhulu. Ukuze kuphuculwe umphumo wokushicilela, i-thinner iya kongezwa ukwenza i-viscosity ihlangabezane neemfuno. Kodwa akunzima ukufumanisa ukuba kwiimeko ezininzi, ukuze ufumane isisombululo esifanelekileyo (isisombululo), kungakhathaliseki ukuba yiyiphi i-viscosity oyisebenzisayo, kusenzima ukufezekisa. ngoba? Emva kophando olunzulu, kwafunyaniswa ukuba i-inki viscosity yinto ebalulekileyo, kodwa kungekhona yodwa. Kukho enye into ebalulekileyo-thixotropy. Ikwachaphazela ukuchaneka koshicilelo.
