FR4 Epoxy Fiberglass Laminated Sheet
Umyalelo weMveliso
Le mveliso ilayitiwe bubushushu obuphezulu kunye noxinzelelo oluphezulu ngelaphu le-glassfiber ye-elektroniki efakwe kwi-brominated epoxy resin.Inezinto eziphezulu zoomatshini, iipropathi ze-dielectric kunye neempawu zokubuyiswa komlilo, ikwanokumelana nobushushu kunye nokumelana nokufuma;
I-FR-4 yikhowudi yebakala lezinto ezichasene nomlilo, oku kuthetha ukuba inkcazo yezinto eziphathekayo kufuneka ikwazi ukucima ngokwayo emva kokutshisa.Ayilogama lezinto eziphathekayo, kodwa ibakala lezinto eziphathekayo.Igama elithi FR4 livela kwinkqubo yokuhlela ye-NEMA apho i-'FR' imele 'isithinteli somlilo', sithobela umgangatho we-UL94V-0.
Ukuthotyelwa kwemigangatho
Ngokuhambelana ne-GB/T 1303.4-2009 yombane we-thermoset resin industrial hard laminates iinkcukacha EPGC202.
Isicelo
Le mveliso isetyenziswa ikakhulu njengenxalenye yesakhiwo seMotor kunye nezixhobo zombane, kubandakanywa zonke iintlobo zokutshintsha, izixhobo zombane, ipleyiti yokuqinisa i-FPC, iibhodi zesekethe zekhabhoni eziprintiweyo, iphedi yokubhola yekhompyuter, ukungunda kunye nezixhobo zokunyibilikisa (ilangatye lovavanyo lwePCB) ifanelekile phantsi kokusingqongileyo okumanzi kunye neoli ye-transformer.

FAQ
I-Q1: Ngaba uyinkampani yokurhweba okanye umenzi?
Singumvelisi ohamba phambili we-composite yokugquma umbane, siye sazibandakanya kumvelisi we-thermoset rigid composite ukususela ngo-2003. Umthamo wethu yi-6000TONS / ngonyaka.
Q2: Iisampuli
Iisampulu zisimahla, kufuneka uhlawule kuphela intlawulo yokuthumela.
I-Q3: Uqinisekisa njani umgangatho wokuvelisa ngobuninzi?
Ngokubonakala, ubungakanani kunye nobukhulu: siya kwenza uhlolo olupheleleyo phambi kokupakisha.
Ngomgangatho wokusebenza: Sisebenzisa ifomyula emiselweyo, kwaye iya kuba kuhlolwa rhoqo isampuli, sinokunika ingxelo yokuhlola imveliso ngaphambi kokuthunyelwa.
I-Q4: Ixesha lokuhambisa
Kuxhomekeke kubungakanani bomyalelo.Ngokuthetha ngokubanzi, ixesha lokuhambisa liya kuba yi-15-20 iintsuku.
Q5: Iphakheji
Siza kusebenzisa iphepha lobuchwephesha lobugcisa ukupakisha kwi-plywood pallet.ukuba uneemfuno zephakheji ezikhethekileyo, siya kupakisha njengemfuno yakho.
Q6: Intlawulo
TT, 30% T/T kwangaphambili ,ibhalansi phambi kokuthunyelwa.Siyayamkela i-L/C.
