Epoxy Laminated Board: Txheej, Txheej Txheem & Kev faib tawm
Epoxy laminated board (epoxy iav ntaub laminate) yog ib qho tseem ceeb insulating khoom siv dav hauv hluav taws xob, hluav taws xob thiab kev lag luam. Nws cov kev ua tau zoo thiab kev siv yog txiav txim siab los ntawm cov khoom siv raw, cov txheej txheem tsim khoom thiab cov khoom tshwj xeeb. Raws li cov txheej txheem kev faib tawm, Weshare muab cov lus qhia dav dav.
1. Raw Materials (Main Components)
Lub rooj tsavxwm yog cov khoom sib xyaw ua los ntawm ob lub hauv paus ntaub ntawv tseem ceeb, nrog rau cov khoom pabcuam ntxiv rau kev hloov kho:
| Qeb | Paub meej |
|---|---|
| Main Resin | Epoxy resin (cov khoom siv matrix) |
| Base ntaub | Cov iav fiber ntau (txhim kho cov cab kuj) |
| Pab txhawb | - Curing agents - Modifiers (flame retardants, etc.) - Fillers - Diluents- Xim pigments thiab lwm yam additives |
Kev sib xyaw ua ke ntawm epoxy resin thiab iav fiber ntau daim ntaub muab cov khoom siv hluav taws xob zoo heev thiab cov khoom siv dag zog, thaum cov khoom siv ntxiv kho cov nplaim hluav taws, xim, kub thiab lwm yam khoom.
2. Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ncaj qha txiav txim siab qhov sib xws thiab kev ua haujlwm ruaj khov ntawm lub rooj tsavxwm. Cov kauj ruam tseem ceeb yog raws li nram no:
Resin Preparation (Tsev)Cov epoxy resin yog tov nrog curing agents, modifiers thiab lwm yam additives los tsim ib tug uniform resin system.
Impregnation (txhim kho)Cov ntaub iav fiber ntau tau dhau los ntawm kev npaj cov tshuaj ua kom tiav thiab txawm tias impregnation.
Slicing (Prepreg Txiav)Daim ntaub impregnated (prepreg) yog txiav rau hauv cov txheej txheem semi-kho cov nplooj ntawv (PP nplooj ntawv).
Lay-up (Stacking)Ntau txheej ntawm prepreg yog stacked raws li qhov yuav tsum tau thickness thiab specifications.
Kub Press CuringCov txheej txheem prepregs raug kho nyob rau hauv qhov kub thiab txias hauv qhov kub xovxwm los tsim cov khoom laminated board.
Ntug Trimming & FinishingLub rooj tsavxwm tsim yog txiav, qhov loj me thiab tshuaj xyuas kom ua tau raws li cov lus qhia zaum kawg.
3. Kev faib khoom
Epoxy boards yog categorized los ntawm ntau qhov ntev kom ua tau raws li ntau hom kev thov.
3.1 Los ntawm Thickness
| Qeb | Thickness Ntau | Tej kev siv |
|---|---|---|
| Ultra{0}} nyias | 0.1-0.3 hli | Precision electronics, nyias rwb thaiv tsev txheej |
| Nyias | 0.4-2.0 hli | PCB substrates, cov khoom siv hluav taws xob |
| Nruab nrab / tuab | 3.0-50 hli | Cov txheej txheem rwb thaiv tsev, transformer qhov chaw |
| Ntxiv - tuab | 50-200 hli | Heavy- cov khoom siv ua haujlwm, cov pwm tshwj xeeb |
3.2 Raws li Standard Size
Txheem qhov ntau thiab tsawgLoj: 40 "× 48", 1020 × 1220 mm
Qhov loj me36 "× 48", 920 × 1220 mm
Loj lojLoj: 48 "× 96", 1220 × 2440 mm
Qhov ntau thiab tsawg: Muaj nyob rau hauv qhov txwv ntawm cov khoom specifications thiab kub xovxwm muaj peev xwm.
3.3 Los ntawm Xim
Dej ntsuab (ib txwm rau FR-4)
Yellow (tus qauv rau 3240)
Dub
Kev cai xim xaiv
3.4 Los ntawm Nplaim Retardancy
Nplaim- qib retardant: Piv txwv li, UL94 V-0 (FR-4)
Tsis yog- nplaim taws- qib retardant: eg, standard 3240 (HB rating)
3.5 Los ntawm Halogen Cov ntsiab lus
Halogen{0}} muaj cov qib
Halogen{0}} qib dawb: RoHS-ua raws, tsis muaj kev cuam tshuam ib puag ncig
3.6 Los ntawm Kub Ua Haujlwm (Tg Tus Nqi)
| Qib | Tg Range | Nta |
|---|---|---|
| Standard Tg | 130-150 degree | General -cov ntaub ntawv siv |
| Nruab nrab -range Tg | 150-170 degrees | Txhim kho thermal stability |
| Siab Tg | 170-210 degrees | Rau siab - kub thiab hnyav ib puag ncig |
3.7 Los ntawm Thawj Daim Ntawv Thov
Kev siv rwb thaiv tsev: Insulating gaskets, barriers, thiab lwm yam.
Cov cuab yeej siv: Polishing fixtures, jigs, kev txhawb nqa
Kho kom zoo nkauj siv: Rooj tog saum npoo npog, zoo nkauj panels
Kev tsim kho siv: Lub hauv paus rwb thaiv tsev, cov txheej txheem teeb meem
Customized daim ntawv thov: Haum rau cov xwm txheej tshwj xeeb hauv kev lag luam
Weshare Cov Lus Qhia:Nkag siab txog kev faib tawm ntawm epoxy boards yog thawj kauj ruam los ua qhov kev xaiv zoo. Weshare muaj ntau yam ntawm epoxy boards nrog cov thicknesses sib txawv, qhov ntau thiab tsawg, xim thiab cov khoom, nrog rau cov kev pabcuam customized (txiav, stamping, CNC machining) kom tau raws li koj qhov project xav tau.
