Technology thiab yam ntxwv ntawm Inkjet Printing thiab Traditional Screen Printing

Nyob rau hauv xyoo tas los no, inkjet luam ntawv txheej txheem ntawm cov cim muaj qhov yooj yim thiab yooj yim vim nws tuaj yeem ua haujlwm ncaj qha raws li cov ntaub ntawv duab, tshem tawm cov txheej txheem tsim cov tshuaj ntsuam uas xav tau los ntawm kev tshuaj ntsuam luam ntawv, thiab siv dav hauv PCBs. kev lag luam. nce ntau. Txawm li cas los xij, vim tias txoj kev luam ntawv dav hlau txawv ntawm txoj kev tshuaj ntsuam luam ntawv, nyob rau hauv cov txheej txheem ntawm kev hloov cov txheej txheem luam ntawv ib txwm siv, cov txheej txheem kev hloov kho kuj tseem tuaj yeem koom nrog, kom lub dav hlau luam ntawv tuaj yeem ua haujlwm zoo dua rau kev tsim khoom ntawm lub tuam txhab cov khoom. Hauv cov txheej txheem ntawm kev ua cov cim PCB, nws yog ib qho tsim nyog los piav qhia txog cov yam ntxwv ntawm inkjet luam ntawv txoj kev.

01

Lub hauv paus ntsiab lus ntawm inkjet luam ntawv

Inkjet luam ntawv yog los tswj cov piezoelectric crystal tivthaiv los ntawm ib tug tej yam tsav tsheb teeb liab, thiab eject discrete ink droplets los ntawm lub nozzle ntawm lub nozzle.

Txij li thaum lub nozzles ntawm industrial-qib inkjet luam ntawv taub hau feem ntau tsuas yog nyob rau hauv qhov kev txiav txim ntawm kaum tawm microns, thiab ib lub nozzle yuav muaj ntau txhiab lub nozzles, lub ntim ejected los ntawm txhua tus number case droplet yog heev me me, xws li tus number case jetted los ntawm lub nozzles. peb siv. Lub dot tsuas yog 13pL, thiab txoj kab uas hla ntawm tus number case dots tsim ntawm lub substrate feem ntau tsuas yog 70-80um.

Txoj kev tshuaj ntsuam luam ntawv ib txwm siv yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam. Nyob rau sab saum toj, cov qauv xav tau yog tsim, thiab qhov loj mesh txiav txim siab qhov zoo ntawm cov qauv.

inkjet luam ntawv number case

Raws li cov lus piav qhia ntawm lub hauv paus ntsiab lus ntawm lub dav hlau luam ntawv, rau inkjet luam ntawv, lub fluidity yuav tsum tau los ntawm tus number case yuav tsum zoo heev, uas yog, nws viscosity yuav tsawg heev, txwv tsis pub tus number case yuav tsis tau ejected ntawm lub nozzle. ntawm lub taub hau luam. Yog li ntawd, inkjet luam ntawv number case peb tau pom yog tsim nyog hu ua number case. Nws viscosity yog ze rau cov dej, thiab viscosity thaum luam ntawv feem ntau yog li 10cps.

Piv nrog rau cov txheej txheem luam ntawv, tus number case yuav tsum khov heev, txwv tsis pub tus number case yuav yooj yim ooze tawm ntawm lub vijtsam mesh, thiab yog tias lub fluidity muaj zog heev, nws yuav nyuaj rau kev tswj, thiab qhov chaw uas yuav tsum tsis txhob muaj tus cwj mem. yuav "nias". Tus number case nkag mus, thiab cov qauv luam ntawv xav tau tsis tuaj yeem tau txais. Piv nrog rau lub dav hlau luam ntawv number case, viscosity ntawm cov tshuaj ntsuam luam ntawv number case yuav yog 4000-10000cps, uas txawv heev.

Qhov sib txawv loj hauv viscosity ntawm inkjet luam ntawv number case thiab tshuaj ntsuam luam ntawv number case yog tshwm sim hauv kev tsim cov cim PCB. Peb yuav pom tias inkjet luam ntawv number case yog rhiab heev rau lub xeev nto ntawm PCB. Yog hais tias qhov nro ntawm lub substrate yog me ntsis txawv ntawm cov luam ntawv number case, jetted number case yuav Ink dots yuav kis tau los yog ntsws, cuam tshuam rau luam ntawv zoo. Lub viscosity ntawm txhob lo lo ntxhuav luam ntawv number case yog siab heev, thiab nws yuav "inert" heev ntawm PCB substrate, thiab nws tsis yooj yim rau kis los yog ntsws ntawm nws tus kheej. Qhov xwm txheej no feem ntau tshwm sim los ntawm qhov tsis tsim nyog siab thiab ceev ntawm lub scraper.

Tsis tas li ntawd, vim yog qhov tsis tshua muaj viscosity ntawm inkjet luam ntawv number case, tus number case muaj pes tsawg leeg sib txawv ntawm silk screen printing number case, thiab whiteness thiab peb-dimensional nyhuv ntawm PCB substrate feem ntau tsis muaj zog tshaj li cov silk screen printing number case. , thiab qee zaum kuv xav tias cov cim silk screen yuav pom meej dua nyob rau hauv cov cim ntawm tib lub thickness thiab loj, tab sis vim hais tias cov qib ntawm cov number case jet printing number case yuav zoo dua, lub dav hlau luam ntawv cim yuav zoo li smoother. Ntawm no, peb yuav tsum ua raws li tus qauv IPC tus qauv - uas yog pom meej meej pom - los txiav txim seb tus cwj pwm zoo raws li qhov yuav tsum tau ua, thiab peb tsis tuaj yeem yuam inkjet luam ntawv thiab silk screen luam ntawv kom zoo ib yam.
