Yuav ua li cas yog cov khoom siv hluav taws xob fiberglass tsim los ntawm cov xov paj?
I. Yarn Pretreatment: Foundation for Precision Weaving
Hluav taws xobfiberglassyarn (electronic yarn luv luv) yog cov khoom siv raw ntawm cov ntaub siv hluav taws xob, nrog cov ntsiab lus tseem ceeb suav nrog G-75 thiab E-225. Nws ib txoj kab uas hla tsuas yog 4-9 microns, zoo dua li tib neeg cov plaub hau. Factory-produced raw yarn yog coated nrog hloov cov hmoov txhuv nplej siab sizing tus neeg saib xyuas los tiv thaiv fiber ntau tawg thiab deformation thiab txhim kho weavability. Txawm li cas los xij, kev ncaj ncaj weaving yog qhov yooj yim rau fuzzing thiab xov paj tawg, ua pretreatment yog qhov tseem ceeb ua ntej.
Cov txheej txheem pretreatment muaj peb kauj ruam tseem ceeb. Ua ntej, twisting: parallel raw yarns yog twisted los txhim kho cohesion thiab mechanical zog thiab tiv thaiv fiber ntau shedding thaum lub sij hawm weaving. Thib ob, warping thiab sizing: yarns yog warped nyob rau hauv batch thiab coated nrog hloov starch sizing los tsim ib tug uniform tiv thaiv zaj duab xis ntawm cov xov paj nto, txo kev sib txhuam poob nyob rau hauv weaving. Qhov thib peb, qhov kub thiab txias txias: warp thiab weft yarns muab tso rau hauv qhov kub thiab txias ib puag ncig (22-26 degree, av noo 60%-70%) kom tshem tawm cov hluav taws xob zoo li qub thiab ruaj khov xov paj, nteg lub hauv paus ruaj khov rau siab -paj precision.
II. High-Precision Weaving: Ntsiab rau Micron-Level Flatness
Weaving yog cov txheej txheem tseem ceeb ntawm kev hloov cov xov paj rau hauv cov ntaub grey. Cov ntaub ntawv hluav taws xob feem ntau siv cov qauv yooj yim weave nrog vertically interlaced warp thiab weft yarns kom ruaj khov ntaub ntom thiab qhov tseeb. Siab- huab cua ceev- dav hlau looms yog cov khoom siv tsim khoom loj. Piv nrog rau cov looms zoo tib yam, huab cua- dav hlau looms siv siab-siab airflow los txhawb cov xov paj weft, featuring ceev ceev thiab kev ua haujlwm nruj, uas zoo txo cov xov paj hnav thiab cov ntaub tsis xws luag.
Cov teeb meem loj hauv kev xaws yog nyob rau hauv kev tswj nruj nruj thiab xoom tsis xws luag kam rau ua. Lub nro yuam kev ntawm warp yarns yog tswj nyob rau hauv ± 5 cN, thiab lub weft xa ceev tseem ceeb tshaj 1000 m / min kom tsis txhob sib sib zog nqus ceev thiab skew distortion. Tag nrho cov txheej txheem tsim khoom yuav tsum muaj tiag - lub sijhawm tshuaj xyuas cov xov paj kom tshem tawm fuzzing, tawg thiab tawg. Cov teeb meem me me no tuaj yeem ua rau luv luv lossis qhib Circuit Court hauv PCB tom ntej. Yog li ntawd, tus nqi tawm los ntawm siab -kawg hluav taws xob ntaub yuav tsum nyob saum 99.5%. Txawm hais tias cov ntaub grey woven yuav siv sij hawm thawj zaug, nws tseem muaj qhov seem ntawm qhov loj me thiab sib txuas tus neeg sawv cev, nrog kev sib txuas ntawm fiber ntau ntawm cov ntsiab lus sib cuam tshuam, yuav tsum muaj ntau yam kev tshaj tawm - cov txheej txheem kho kom tau raws li cov qauv zoo.
III. Desizing thiab Fiber qhib: Cov txheej txheem tseem ceeb rau Resin Compatibility
Tom qab- kev kho mob ntawm cov ntaub grey suav nrog ob theem tseem ceeb: thermal desizing thiab fiber ntau qhib & flattening, aiming kom tshem tawm cov organic residues thiab optimize fiber ntau kom zoo meej compatibility nrog epoxy resin.
1. Thermal Desizing: Ua kom tiav tshem tawm ntawm Organic impurities
Residual sizing thiab deg tshuaj tiv thaiv resin nkag mus. Ob -theem desizing yog saws rau kev tu kom huv si. Ua ntej-desizing yog ua nyob rau ntawm 200-300℃kom tshem tawm cov organic tshuaj tsis hloov pauv, ua raws li siab -kub thermal desizing nyob rau hauv 500-600℃cub rau sib sib zog nqus pyrolysis, txo cov organic residue mus rau hauv qab 0.1%. Tom qab desizing, cov ntaub nthuav tawm cov dawb huv thiab huv fiber ntau nto, npaj rau kev kho deg tom ntej.
2. Fiber Opening & Flattening: Optimization ntawm Fabric Structure
Fibers ntawm warp- weft kev sib tshuam yog nruj nruj tom qab desizing, ua rau cov resin permeability tsis zoo. Siab - kev kho dej siab yog siv rau kev qhib fiber ntau. Nyob rau hauv siab -kev cuam tshuam dej siab (100–200 MPa), cov ntaub qhwv cov ntaub qhwv sib npaug sib npaug thiab ua kom tiaj tus los tsim cov qauv ntaub. Cov txheej txheem no muab lub ntsej muag smoother, cov tuab tuab (kev ua siab ntev ± 2 μm), thiab ntau dua 30% resin nkag mus ua haujlwm. Nws kuj tseem nthuav dav thaj chaw sib txuas ntawm fibers thiab resin, zoo heev txhim kho qhov kub thiab txias thiab txhua yam muaj zog ntawm tooj liab- clad laminates. Fiber qhib yog ib qho tseem ceeb ntawm cov txheej txheem rau high{13}}kawg hluav taws xob fabrics xws li 7628 thiab 2116 specifications, ncaj qha txiav txim siab nws adaptability rau siab - zaus thiab siab - daim ntawv thov ceev.
IV. Surface Chemical Treatment: Endowing Core Material Properties
Tom qab qhib fiber ntau, cov ntaub ntawv hluav taws xob tau txais kev kho mob silane coupling tus neeg saib xyuas, txheej txheem tseem ceeb los txhim kho kev rwb thaiv tsev, tiv thaiv tshav kub thiab resin adhesion. Cov tshuaj kho yog tsim nrog silane coupling agents thiab functional additives, ua ib nano-scale organic zaj duab xis rau ntawm fiberglass nto.
Cov txheej txheem kho cov txheej txheem: ntaub impregnation → uniform extrusion (kua cov ntsiab lus tswj ntawm 15% – 20%) → staged drying (pre- ci ntawm 80℃thiab curing ntawm 150℃). Cov yeeb yaj kiab organic no muab peb lub luag haujlwm tseem ceeb: ua ntej, ntxiv dag zog rau cov rwb thaiv tsev los ntawm kev ua kom lub ntim tiv taus thiab kev tawg hluav taws xob kom tau raws li PCB siab - qhov yuav tsum tau muaj hluav taws xob rwb thaiv tsev; thib ob, txhim kho resin affinity los tsim tshuaj bonds ntawm fiberglass thiab epoxy resin thiab tiv thaiv delamination thiab tev; thib peb, txhim kho thermal stability kom muaj kev ncaj ncees ntawm cov qauv saum toj 280℃thiab hloov mus rau kev coj ua - cov txheej txheem dawb soldering.
V. Precision Inspection & Cov Khoom tiav: Txhim khu kev ntseeg tau zoo
Nto-kho hluav taws xob cov ntaub ntawv ua tiav tag nrho- ntau yam kev tshuaj xyuas ua ntej slitting thiab winding rau hauv cov yob tiav (2000-4000 meters ib yob). Kev ntsuam xyuas nruj suav nrog cov tsos, qhov ntev thiab qhov ntsuas qhov ua tau zoo:
Kev tshuaj xyuas qhov tshwm sim: Siab-txhais pom kev soj ntsuam nrog xoom kam rau fuzzing, tawg filaments, stains thiab ntom tsis xws luag;
Dimensional soj ntsuam: Laser thickness ntsuas (piv txwv li, 7628 npuag: approx. 0.18 hli; 2116 ntaub: approx. 0.10 hli) nrog thickness yuam kev Tsawg dua los yog sib npaug rau ± 2 μm; npuag dav tswj ntawm 1270 ± 10 hli;
Kev Ntsuas Kev Ua Haujlwm: Verification of areal density, breaking strength, insulation resistance and resin wettability to comply with IPC-4412 and other copper-clad laminate industry standards.
Tsuas yog cov khoom tsim nyog tuaj yeem xa tau raws li qib siab -kawg hluav taws xob fabrics thiab muab rau tooj liab- clad laminate thiab PCB cov tuam txhab, ua haujlwm tseem ceeb xws li 5G hauv paus chaw nres tsheb, AI servers thiab lub zog tshiab tsheb hluav taws xob.
Los ntawm micron- qib fiberglass yarn mus rau siab -kawg hluav taws xob ntaub, tag nrho cov txheej txheem tsim muaj rau 6 qhov txuas: pretreatment, weaving, desizing, fiber ntau qhib, kho deg thiab soj ntsuam precision. Txhua txoj kev sib koom ua ke txiav- thev naus laus zis hauv cov tshuab precision, khoom siv chemistry thiab textile engineering. Qhov zoo ntawm cov khoom siv hluav taws xob tseem ceeb qhia txog kev tsim khoom raug thiab cov qauv tswj kom zoo. Nws yog kev nrhiav kev ua haujlwm zoo heev uas ua rau cov ntaub fiberglass los txhawb txoj kev loj hlob ntawm siab - zaus thiab siab -kev lag luam hluav taws xob ceev, ua haujlwm tseem ceeb.micron-scale qaumntawm niaj hnub electronic manufacturing.
