PCB number case yog hais txog tus cwj mem siv hauv cov ntawv luam tawm Circuit boards. Nyob rau hauv lub luam tawm hauv Circuit Court board kev tsim khoom, kev tshuaj ntsuam luam ntawv yog ib qho ntawm cov txheej txheem tseem ceeb uas tsis tseem ceeb. Txhawm rau kom tau txais kev ncaj ncees ntawm cov duab luam tawm, tus cwj mem yuav tsum yog qhov zoo heev. PCB tus lej zoo nyob ntawm seb cov mis yog kev tshawb fawb, qib siab thiab ib puag ncig zoo. Nws yog embodied nyob rau hauv:

Viscosity yog luv rau dynamicviscosity. Qhov viscosity feem ntau yog qhia raws li qhov kev nyuab siab ntawm cov dej ntws faib los ntawm qhov nrawm gradient nyob rau hauv cov lus qhia ntawm txheej txheej, hauv Si pas/SEC (Pa). S) lossis millipas/thib ob (mPa) Kev S). Hauv PCB ntau lawm hais txog fluidity ntawm number case tsav los ntawm sab nraud rog.

Kev sib txuas ntawm viscosity unit:

1. de pab. S = 10 p = 1000 mpa. S = 1000CP = 10dpa.s

2. Plasticity hais txog number case deformation los ntawm sab nraud quab yuam, tseem tuav nws deformation ua ntej qhov xwm. Cov yas yas ntawm tus lej yog qhov ua tau zoo los txhim kho kev luam ntawv raug;

3. Thixotropic (thixotropic) number case nyob rau hauv lub static gelatinous, thiab thaum kov los ntawm ib tug hloov nyob rau hauv viscosity ntawm ib tug khoom, kuj hu ua co, ntws kuj;

Kev tsom xam ntawm kev ua haujlwm ntawm PCB number case txheej txheem

4. Liquidity (leveling) number case nyob rau hauv qhov kev nqis tes ua ntawm sab nraud, mus rau qhov kis ntawm ib puag ncig. Fluidity yog qhov sib txawv ntawm viscosity, fluidity thiab number case yas thiab thixotropy. Loj plasticity thiab thixotropy, loj fluidity; Lub imprinting yog ib qho yooj yim mus nthuav nrog high fluidity. Me me fluidity, yooj yim rau pom net, number case tshwm sim, kuj hu ua reticulation;

5. Viscoelasticity yog hais txog tus number case nyob rau hauv lub scraper tom qab scraping, tus number case yog txiav thiab tawg sai sai rebound kev ua tau zoo. Luam ntawv deformation deformation ceev, tus lej thim rov qab sai los pab txhawb kev luam ntawv;

6. Kev ziab kom qhuav ntawm tus lej ntawm lub vijtsam kom qhuav qeeb dua qhov zoo dua, thiab cia siab tias yuav hloov tus lej mus rau txheej txheej, sai dua qhov zoo dua;

7. Fineness pigment thiab khoom particle loj, PCB number case feem ntau tsawg dua 10μm, fineness yuav tsum tsawg tshaj li ib feem peb ntawm lub mesh qhib;

8. Drawing number case spatula tuaj tos tus number case, filamentous number case stretching tsis tawg degree hu ua daim duab. Cov kua mem ntev, cov kua nplaum thiab cov ntawv luam tawm zoo li muaj ntau cov filaments, yog li cov substrate thiab phaj qias neeg, txawm tias tsis tuaj yeem luam tawm;

9. Ink pob tshab thiab zais lub zog

Txog PCB tus lej, raws li kev siv thiab xav tau ntawm cov xim sib txawv sib txawv thiab zais lub zog tseem tso tawm ntau yam kev xav tau. Feem ntau, kab ntawv tus lej, tus lej coj tus cwj pwm thiab tus lej tus cim, yuav tsum muaj lub zog zais siab. Thiab flux tsis kam yog hloov tau yooj yim dua.

10. Tshuaj lom neeg tsis kam ntawm tus number case

PCB number case raws li kev siv ntau lub hom phiaj, cov kev cai sib xws ntawm cov kua qaub, alkali, ntsev thiab cov kuab tshuaj muaj cov qauv nruj;

11. Lub cev yam ntxwv ntawm tus cwj mem tsis kam

PCB number case yuav tsum tiv taus khawb sab nraud, poob siab thaum tshav kub kub, tshem tawm cov tshuab ua haujlwm, thiab ua tau raws li ntau yam kev siv hluav taws xob nruj;

12. Kev siv number case kev nyab xeeb thiab kev tiv thaiv ib puag ncig

PCB number case yuav tsum tsis muaj tshuaj lom, tsis muaj ntxhiab, kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
