Kaya mtundu wa PCB inki ndi yabwino kwambiri, kwenikweni, ndizosatheka kusiya kuphatikiza zigawo zazikuluzikuluzi. Ubwino wabwino wa inki ndi chiwonetsero chokwanira cha sayansi, kupita patsogolo komanso kuteteza chilengedwe. Zimawonetsedwa mu:

Viscosity ndiye chidule cha dynamic viscosity. Kawirikawiri amasonyezedwa ndi mamasukidwe akayendedwe, ndiko kuti, kukameta ubweya wa kumeta ubweya wa madzimadzi ogawanika ndi liwiro la gradient kumalo othamanga, gulu lapadziko lonse ndi Pa/sec (Pa.S) kapena milliPascal/sec (mPa.S). Mu kupanga PCB, amatanthauza fluidity inki opangidwa ndi mphamvu zakunja.

Ubale wa kutembenuka kwa viscosity unit:

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

Plasticity imatanthauza kuti inki ikapunthwa ndi mphamvu yakunja, imasungabe katundu wake asanapangidwe. Pulasitiki ya inki imathandizira kuwongolera kulondola kosindikiza;

Inki ya thixotropic (thixotropic) ndi gelatinous ikaima, ndipo kukhuthala kumasintha akakhudza. Amatchedwanso thixotropic ndi anti-sagging;

Fluidity (leveling) Momwe inki imafalikira mozungulira ndi mphamvu yakunja. Fluidity ndi kubwereza kwa mamasukidwe akayendedwe, ndipo fluidity imagwirizana ndi pulasitiki ndi thixotropy wa inki. Mapulasitiki ndi thixotropy ndi aakulu, fluidity ndi yaikulu; fluidity ndi yaikulu, chizindikirocho ndi chosavuta kuwonjezera. Small liquidity, zosavuta kuoneka ukonde, chifukwa mu chodabwitsa cha inki mapangidwe, amatchedwanso ukonde;

Viscoelasticity imatanthawuza kuthekera kwa inki yomwe imametedwa ndi kuthyoledwa pambuyo poti inkiyo ikuphwanyidwa ndi squeegee kuti ibwererenso mwamsanga. Pamafunika kuti inki deformation liwiro mofulumira ndi inki rebounds mwamsanga kukhala opindulitsa kusindikiza;

Kuwuma kumafuna kuti inki iume pazenera pang’onopang’ono, ndipo tikuyembekeza kuti inki ikasamutsidwa ku gawo lapansi, ndiye kuti mofulumira kwambiri;

Kukula kwa fineness pigment ndi olimba zinthu particles, PCB inki zambiri zosakwana 10μm, ndi kukula kwa fineness ayenera kukhala osachepera gawo limodzi mwa magawo atatu a mauna kutsegula;

Pamene fosholo ya inki ikugwiritsidwa ntchito ponyamula inki, mlingo umene inki yonyezimira siimathyoka ikatambasula imatchedwa stringiness. Ulusi wa inki ndi wautali, ndipo pali ulusi wambiri pamwamba pa inki ndi malo osindikizira, zomwe zimapangitsa kuti gawo lapansi ndi mbale yosindikizira zikhale zodetsedwa komanso zosakhoza kusindikiza;

Transparentness ndi kubisa mphamvu ya inki

Pakuti inki PCB, malingana ndi ntchito zosiyanasiyana ndi zofunika, zofunika zosiyanasiyana zimaperekedwanso poyera ndi kubisala mphamvu ya inki. Nthawi zambiri, ma inki ozungulira, ma inki oyendetsa ndi ma inki amafunikira mphamvu zobisalira. Kukana kwa solder kumakhala kosavuta.

Chemical kukana kwa inki

Ma inki a PCB ali ndi miyezo yolimba ya asidi, alkali, mchere ndi zosungunulira malinga ndi cholinga cha ntchito;

Kukaniza thupi kwa inki

PCB inki ayenera kukumana kukana zikande kunja, kukana matenthedwe mantha, makina peel kukana, ndi kukwaniritsa zosiyanasiyana okhwima magetsi ntchito zofunika;

Chitetezo ndi kuteteza chilengedwe kwa inki

Ma inki a PCB amafunikira kuti asakhale oopsa, osanunkhiza, otetezeka komanso okonda zachilengedwe.

Pamwambapa tafotokoza mwachidule za ma inki khumi ndi awiri a PCB. Pakati pawo, mu ntchito yeniyeni ya kusindikiza chophimba, vuto la mamasukidwe akayendedwe limagwirizana kwambiri ndi woyendetsa. Kukhuthala kwake ndikofunikira kwambiri pakusalala kwa chophimba cha silika. Choncho, mu PCB inki zikalata luso ndi malipoti QC, mamasukidwe akayendedwe bwino chizindikiro, kusonyeza pansi pa zimene ndi mtundu wanji kukhuthala kuyesa chida ntchito.

Mu ndondomeko yeniyeni yosindikizira, ngati mamasukidwe a inki ali okwera kwambiri, zimakhala zovuta kusindikiza, ndipo m’mphepete mwazithunzizo zidzakhala zovuta kwambiri. Pofuna kupititsa patsogolo kusindikiza, chowonda chidzawonjezedwa kuti chiwongolero cha viscosity chikwaniritse zofunikira. Koma sikovuta kupeza kuti nthawi zambiri, kuti mupeze chisankho choyenera (chigamulo), ziribe kanthu momwe mumagwiritsa ntchito mamasukidwe amtundu wanji, sikutheka kukwaniritsa. chifukwa chiyani? Pambuyo pofufuza mozama, adapeza kuti kukhuthala kwa inki ndi chinthu chofunikira, koma osati chokhacho. Palinso chinthu china chofunika kwambiri-thixotropy. Zikukhudzanso kulondola kwa zosindikiza.
