Pcbink ink inoreva inki inoshandiswa muPrinted Circuit board. Mu yakadhindwa redunhu bhodhi kugadzira maitiro, kudhinda skrini ndeimwe yeakakosha maitiro akakosha. Kuti uwane kutendeseka kwekuberekwa kwemifananidzo, inki inofanirwa kunge iri yemhando yepamusoro. PCB inki mhando zvinoenderana nekuti formula ndeyesainzi, yepamusoro uye ine hushamwari kwezvakatipoteredza. Icho chakasimbiswa mu:

Viscosity ipfupi kune dynamicviscosity. Iyo viscosity inowanzo kuratidzwa seyekuveura kushushikana kwemvura inoyerera yakakamurwa nevelocity gradient munzira yekuyerera layer, muSi pas/SEC (Pa). S) kana millipas/second (mPa). S). MuPCB kugadzirwa kunoreva kuyerera kweinki inofambiswa nemasimba ekunze.

Shanduko hukama hwe viscosity unit:

1. Zvepa. S = 10 p = 1000 mpa. S=1000CP=10dpa.s

2. Plasticity inoreva inki deformation nesimba rekunze, ichiri kuchengetedza deformation yayo pamberi pezvisikwa. Iyo plastiki yeinki inobatsira pakuvandudza kudhinda kurongeka;

3. Thixotropic (thixotropic) ink muiyo static gelatinous, uye kana ikabatwa neshanduko mune viscosity yeimba, inozivikanwawo sekuzunza, kuyerera kuramba;

Ongororo yehunyanzvi hwekuita kwePCB inki process

4. Liquidity (kuenzanisa) inki pasi pechiito chemasimba ekunze, kusvika padanho rekupararira kwakatenderedza. Fluidity ndiyo inodzokororwa ye viscosity, fluidity uye inki plastiki uye thixotropy. Huru plastiki uye thixotropy, yakakura fluidity; Iko kudhinda kuri nyore kuwedzera neakakwira fluidity. Diki fluidity, nyore kuoneka mambure, inki chiitiko, inonziwo reticulation;

5. Viscoelasticity inoreva inki mu scraper mushure mekukwesha, iyo inki inochekwa uye yakatyoka nekukurumidza rebound performance. Kudhinda inki deformation kumhanya, ingi rebound nekukurumidza kuti iite kudhinda;

6. Kuomesa zvinodiwa neingi pachiratidziro kuomesa zvishoma nezvishoma zviri nani, uye tariro yekuendesa ingi kune substrate, nekukurumidza zviri nani;

7. Fineness pigment uye yakasimba particle size, PCB inki kazhinji isingasviki 10μm, kunaka kunofanira kunge kuri pasi pechikamu chimwe chete muzvitatu chekuvhura mesh;

8. Kudhirowa inki spatula kuti utore ingi, filamentous ingi kutambanudza haina kuputsika dhigirii inozivikanwa sokudhirowa. Long ingi, ingi pamusoro uye kudhinda pamusoro kuoneka yakawanda filaments, kuitira kuti substrate uye ndiro yakasviba, kunyange haigone kudhinda;

9. Ingi pachena uye kuvanza simba

Nokuti PCB ingi, maererano kushandiswa uye zvinodiwa zvakasiyana ingi pachena uye kuvanda simba akaisawo mberi siyana zvinodiwa. Kazhinji, mutsetse ingi, conductive ingi uye hunhu ingi, zvinodiwa kuva yakakwirira kuvanda simba. Uye kupikisa kweflux kunowedzera kushanduka.

10. Kemikari kuramba kweinki

PCB inki maererano nekushandiswa kwezvinangwa zvakasiyana, izvo zvinoenderana nezvinodiwa zveasidhi, alkali, munyu uye zvinonyungudutsa zvinodiwa zvine mipimo yakasimba;

11. Hunhu hwemuviri hwekuramba inki

PCB inki inofanirwa kushingirira kune ekunze makwara, kupisa kuvhunduka, mechanic peeling, uye kusangana neyakaomesesa magetsi ekuita zvinodiwa;

12. Kushandiswa kwekuchengetedza inki nekuchengetedzwa kwezvakatipoteredza

PCB inki inoda yakaderera chepfu, kunhuhwirira, kuchengeteka uye kuchengetedzwa kwezvakatipoteredza.
