Hore na boleng ba PCB enke e babatsehang, ka molao-motheo, ho ke ke ha khoneha ho arohana le motsoako oa likarolo tse ka holimo tse ka sehloohong. Boleng bo babatsehang ba enke ke ponahatso e felletseng ea mahlale, tsoelo-pele le tšireletso ea tikoloho ea foromo. E bonahala ho:

Viscosity ke khutsufatso ea viscosity e matla. Ka kakaretso e bontšoa ke viscosity, ke hore, khatello ea ho kuta ea phallo ea mokelikeli e arotsoe ke lebelo la lebelo ho ea ho lera la phallo, sehlopha sa machaba ke Pa/sec (Pa.S) kapa milliPascal/sec (mPa.S). Ka PCB tlhahiso, e bua ka fluidity ea enke hlahisoang ke matla a ka ntle.

Kamano ea phetoho ea yuniti ea viscosity:

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

Plasticity e bolela hore ka mor’a hore enke e holofatsoe ke matla a ka ntle, e ntse e boloka thepa ea eona pele e fetoha. Plastiki ea enke e thusa ho ntlafatsa ho nepahala ha khatiso;

Enke ea thixotropic (thixotropic) ke gelatinous ha e eme, ‘me viscosity e fetoha ha e ama. E boetse e bitsoa thixotropic le anti-sagging;

Fluidity (leveling) /fluidity/ Boemo boo enke e phatlallang ka yona tlasa ketso ya matla a kantle. Fluidity ke phetoho ea viscosity, ‘me fluidity e amana le polasetiki le thixotropy ea enke. Plastiki le thixotropy li kholo, mokelikeli o moholo; mokelikeli o moholo, khatiso e bonolo ho atolosa. Mokelikeli o monyenyane, o bonolo ho hlaha ka marang-rang, o bakang ts’ebetso ea ho thehoa ha enke, e tsejoang hape e le netting;

Viscoelasticity e bolela bokhoni ba enke e kutang le ho pshatleha ka mor’a hore enke e hlajoe ke squeegee ho khutlela morao kapele. Ho hlokahala hore lebelo la deformation ea enke le potlake ‘me enke e khutlele kapele ho ba molemo ho hatisa;

Ho omella ho hloka hore enke e ome skrineng butle-butle kamoo ho ka khonehang, ‘me ho na le tšepo ea hore ka mor’a hore enke e fetisetsoe substrate, kapele ho molemo;

Boholo ba pigment ea fineness le likaroloana tse tiileng, enke ea PCB hangata e ka tlase ho 10μm, ‘me boholo ba fineness e lokela ho ba tlase ho karolo ea boraro ea ho bula ha letlooeng;

Ha kharafu ea enke e sebelisoa ho nka enke, tekanyo eo enke ea filamentous e sa robeheng ha e otlolloa e bitsoa stringiness. Enke khoele e telele, ‘me ho na le likhoele tse ngata holim’a enke holim’a enke le holim’a khatiso, tse etsang hore substrate le poleiti ea khatiso li silafetse esita le ho sitoa ho hatisa;

Ho sebeletsa pepeneneng le ho pata matla a enke

Bakeng sa li-inks tsa PCB, ho latela ts’ebeliso le litlhoko tse fapaneng, litlhoko tse fapaneng li behiloe hape bakeng sa ho pepeseha le ho pata matla a enke. Ka kakaretso, li-inks tsa potoloho, li-inks tsa conductive le li-inks kaofela li hloka matla a holimo a ho pata. Ho hanyetsa ha solder ho bonolo haholoanyane.

Khanyetso ea lik’hemik’hale ea enke

Li-inks tsa PCB li na le litekanyetso tse thata tsa acid, alkali, letsoai le li-solvents ho latela morero oa tšebeliso;

Ho hanela enke ‘meleng

Enke ea PCB e tlameha ho kopana le khanyetso ea kantle, ho hanyetsa mocheso oa mocheso, ho hanyetsa lekhapetla la mochini, le ho fihlela litlhoko tse fapaneng tse thata tsa ts’ebetso ea motlakase;

Polokeho le ts’ireletso ea enke

Li-inks tsa PCB li hlokoa hore li be le chefo e tlase, li se na monko, li bolokehe ebile li se ke tsa senya tikoloho.

Ka holimo re akarelitse thepa ea mantlha ea li-inks tse leshome le metso e ‘meli tsa PCB. Har’a bona, ts’ebetsong ea sebele ea khatiso ea skrine, bothata ba viscosity bo amana haufi-ufi le mosebeletsi. Viscosity e bohlokoa haholo ho boreleli ba skrine ea silika. Ka hona, litokomaneng tsa tekheniki tsa enke tsa PCB le litlaleho tsa QC, viscosity e tšoailoe ka ho hlaka, e bontšang tlas’a maemo afe le mofuta ofe oa lisebelisoa tsa ho hlahloba viscosity tse lokelang ho sebelisoa.

Ts’ebetsong ea sebele ea khatiso, haeba viscosity ea enke e phahame haholo, ho tla ba thata ho e hatisa, ‘me metse e meholo ea litšoantšo e tla senyeha haholo. E le ho ntlafatsa phello ea khatiso, ho tla eketsoa motho e mosesaane ho etsa hore viscosity e finyelle litlhoko. Empa ha ho thata ho fumana hore maemong a mangata, e le hore u fumane qeto e nepahetseng (qeto), ho sa tsotellehe hore na u sebelisa viscosity efe, ho ntse ho ke ke ha khoneha ho e finyella. hobaneng? Ka mor’a lipatlisiso tse tebileng, ho ile ha fumanoa hore viscosity ea enke ke ntho ea bohlokoa, empa eseng eona feela. Ho na le ntlha e ‘ngoe ea bohlokoa haholo-thixotropy. E boetse e ama ho nepahala ha khatiso.
