Lub luag hauj lwm dab tsi ua Heated Platens Ua si hauv kev kho cov kab hluav taws xob ntawm cov iav hloov tau yooj yim?

Ib tiam tshiab ntawm cov ntxaij vab tshaus hloov tau yooj yim, rollable thiab nyias - zaj duab xis sensors yog tsim los ntawm ib qho tshiab substrate: iav thinner dua tib neeg cov plaub hau, saj zawg zog txaus khoov, tseem meej kiag li. Lub tshuab hluav taws xob hluav taws xob ntawm lub iav willow no yog luam tawm nrog tus cwj mem tshwj xeeb ua los ntawm cov nyiaj los yog tooj liab nanoparticles. Tus number case yuav tsum tau sintered - ci ntawm ib qho tshwj xeeb, nruab nrab qhov kub thiab txias - kom fuse cov hlau hais mus rau hauv ib qho khoom, cov kab hluav taws xob tsis muaj melting, warping los yog cracking lub ilv, ultra- iav nyias. Qhov no rhiab thermal kho yog ua nyob rau hauv ib tug rhuab platen. Nws yog qhov muag muag, kub theem rau cov khoom siv hluav taws xob yav tom ntej.

Cov txheej txheem Sintering Conductive Inks ntawm Flexible Glass
Yuav Siv Cov Phaj Rhaub Li Cas
Cov ntawv luam tawm hloov pauv tau muab tso rau hauv ib lub tiaj kub platen. Lub platen feem ntau yog tsim los ntawm cov khoom siv nrog cov coefficient tsawg heev ntawm thermal expansion (xws li Invar lossis iav -ceramic xws li Zerodur) thiab ua kom muaj qhov kub thiab txias, feem ntau ntawm 150℃thiab 250℃. Qhov no me me, txawm tias kub sinters tus number case tsis muaj thermal shock lossis distortion ntawm iav. Lub platen nto yuav tsum du thiab tsis muaj particle dawb. Feem ntau lub platen nto yog coated nrog ib tug uas tsis yog - nplaum PTFE txheej los tiv thaiv adhesion ntawm cov ntawv luam tawm qauv rau lub platen thiab kom yooj yim tshem tawm ntawm kho substrate. Qhov tshwm sim yog qhov hloov pauv, pob tshab thiab ua haujlwm tau zoo hauv hluav taws xob hluav taws xob ntawm lub substrate uas tuaj yeem khoov ib puas txhiab zaus yam tsis muaj kev tawg.

Lub luag haujlwm tseem ceeb ntawm Thermal Uniformity thiab Stability
Lub platen yog ib qho flawlessly tiaj tus, thermally me me, ultra- lub txaj huv uas ci ib lub voj voog layout rau ntawm daim iav nyias dua li ntawv. Kev tsim cov txheej txheem ntawm rhuab platen conductive number case saj zawg zog iav yuav tsum tau tshwj xeeb kub zoo sib xws ntawm tag nrho cov platen nto, feem ntau nyob rau hauv ± 2 degree. Ib qho chaw kub kub hauv zos yuav cuam tshuam lub iav los yog dhau sinter tus number case. Ib qhov chaw txias yuav tawm hauv tus number case nyob rau hauv sintered thiab tsis conductive. Qhov qis-thermal-expansion qauv ntawm lub platen xyuas kom meej tias qhov flatness tsis hloov nrog qhov kub thiab txias, ua kom sib raug zoo ntawm cov iav thiab cov platen nto. Lub platen yog mounted rau ntawm ib tug nquag damped thav duab kom txo tau kev co thiab mechanical shock, vim hais tias txav thaum lub sij hawm sintering yuav smear lub nyias conductive kab.

Txheej Txheem Lus Cim: Inert Gas Atmosphere rau Copper Nanoparticle Ink
Nyob rau hauv cov ntaub ntawv tus cwj mem conductive yog raws li tooj liab nanoparticles (pheej yig dua thiab ntau conductive tshaj nyiaj), ib tug inert gas cua (nitrogen los yog argon) yuav tsum tau nyob rau hauv lub sintering chamber. Thaum kub kub, tooj liab oxidises sai heev, tsim ib txheej uas tsis yog -conductive tooj liab oxide nyob rau saum npoo ntawm nanoparticles. Qhov oxidation no cuam tshuam qhov kev sib xyaw kom zoo ntawm cov khoom thiab ua kom muaj zog tiv thaiv hluav taws xob. Txhawm rau zam qhov no, cov rhuab platen yog nyob ib puag ncig los ntawm lub chamber uas yog dej ntws nrog siab purity nitrogen (cov ntsiab lus oxygen.<50 ppm) before and throughout the sintering cycle. This same inactive environment also shields the pliable glass substrate from the stress generated by moisture. For silver-based inks a nitrogen atmosphere is optional but is commonly used anyway to maintain a clean, contamination-free environment.

Technical Accuracy: Precise Temperature Management thiab Vibration Isolation
Sintering kub ntau yam
Lub sintering kub yog qhov tseem ceeb thiab yuav tsum tau tswj nyob rau hauv lub qhov rais nruj heev, feem ntau ± 2 degree. Silver nanoparticle inks yog qhov zoo tshaj plaws sintered ntawm qhov kub ntawm qhov nruab nrab ntawm 150℃thiab 200 degree, thaum tooj liab inks yuav tsum tau ib tug me ntsis siab kub ntawm ib ncig ntawm 200-250℃account rau ntau refractory xwm ntawm tooj liab, thaum tseem tshuav nyob rau hauv qab lub iav hloov kub ntawm tej polymer overcoat txheej. Lub rhuab platen yog muab nrog ib tug xov tooj ntawm embedded thermocouples (feem ntau yog ib tug ntawm 100 cm2 ntawm qhov chaw) thiab ib tug PID maub los tswj hluav taws xob cua sov ntsiab (xws li, cartridge heaters los yog etched foil heaters) nyob rau sab nraum qab ntawm lub platen.

Mechanical Isolation thiab Vibration
The platen should be constructed to minimise any vibration or mechanical shock. Even micro-scale vibrations (amplitude >0.5 µm) thaum lub sij hawm sintering txheej txheem yuav ua rau cov dej tsis sib xws ntawm cov kua number case ua ntej solidifying, ua rau cov kab tawg los yog cov kab tsis zoo. Yog li ntawd lub platen sib dhos yog sib cais los ntawm lub tsev vibrations, siv pneumatic isolators los yog active piezoelectric dampers. Qhov ua tiav cua sov theem yog mounted ntawm ib tug hnyav granite puag kom dampen tsawg zaus cuam tshuam.

Xaus: Fais fab rau yav tom ntej ntawm Flexible Electronics
Lub rhuab platen yog ib tug me me, precision thermal cuab tam uas sinters cov hluav taws xob circuits mus rau lub breakthrough saj zawg zog iav substrates, ua rau cov tiam tom ntej ntawm bendable, unbreakable qhia thiab sensors. Lub platen muab cov khoom zoo sib xws, qis- kub kub hauv kev ua tib zoo tswj, kev co -dawb thiab (qhov xav tau) inert cua kom tig cov ntawv luam tawm nanoparticle inks rau hauv kev ntseeg tau, cov khoom siv hlau zoo heev yam tsis tau rhuav tshem cov iav ultrathin. Lub neej yav tom ntej ntawm cov khoom siv hluav taws xob hloov pauv tau raug ci rau ntawm iav los ntawm lub tiaj tiaj tiaj tiaj, sov phaj - softly, meej thiab tsis muaj ib qho tawg lossis warp.
