▲ Faʻafanua filifilia filifiliga (punavai: puna “GJB 4057-2000 Lolomiina Lolomi Komiti Komiti Faatino matagaluega Manaoga mo Militeli eletise meafaigaluega”)

Noun faʻamatalaga

FR-4

Fr-4 o se afi teteʻe mea vasega vasega, o loʻo faʻalia ai le uiga o le resin mea i le maeʻa ai o le susunuina tulaga tatau ona mafai ona ia lava-tineia se mea faʻapitoa, e le o se igoa mea, ae o se mea masani vasega.

Tg / tioata liua vevela

Tg aoga e faʻatatau i le vevela lea e suia ai mea mai le sili atu ona maʻaʻa tioata tulaga i le sili atu ofuvae ma fetuʻunaʻi tulaga paʻu. Manatua o mea totino suia i luga atu o Tg.

CTI

CTI: Faʻatusatusaga Suʻesuʻe Faʻasino Igoa, faʻapuʻupuʻu o Faʻatusatusaga Suʻesuʻega Faasino.

Uiga: o le faʻailoga o le leakage tetee. I le setete o le faʻaogaina o le voltage i le pito i luga o mea e faʻamama ai mea, faʻapa’ū ifo le pa’ū o le electrolytic i luga o le gaosia o oloa i le va o electrodes, ma iloilo le volitiga seʻia leai se afaina o leiti.

Laʻasaga CTI: o le tulaga CTI mai le 0 i le 5. O le laʻititi le numera, o le maualuga le teteʻe leakage.

PI

Polyimide (PI) o se tasi o le organic polymer mea ma le sili lelei faʻatinoina faatinoga.O lona maualuga vevela teteʻe atu i le 400 ℃ i luga, umi-faʻaaogaina vevela vevela o -200 ~ 300 ℃, vaega o le leai se vaʻaia faʻaliliuga maualuga, maualuga faʻatinoina faatinoga, 103 hz dielectric tumau 4.0, dielectric leiloa na o le 0.004 ~ 0.007, auai i le F ia H.

CE

(1) CE cyanate resin o se fou ituaiga o mea faʻaeletoroni ma mea faʻapipiʻi, o se tasi o le taua faʻavae mea i le matata o mea faʻaeletise ma eletise fesoʻotaʻiga. O se sili lelei resin matrix mea mo radome. Ona o lona lelei vevela mautu ma le vevela teteʻe, maualalo laina faʻalautelega coefficient ma isi tulaga lelei, CE resin ua avea ma sili lelei matrix mea mo le gaosiga o maualuga maualuga, maualuga faʻatinoga, tulaga maualuga eletise lolomi laupapa matagaluega; I se faʻaopopoga, CE resin o se lelei chips afifi mea.

(2) E mafai ona faʻaaogaina le resin CE mo le gaosiaina o vaegaʻau, vaʻalele, vaʻalele, faʻavasegaga faʻavae vaega, pei o apaʻau, atigi vaʻa, ma isi mea, ae mafai foi ona faia i totonu o aerospace foam sanuisi mea masani e masani ona faʻaaogaina.

(3) CE resin e lelei fetaui, ma epoxy resin, unsaturated polyester ma isi copolymerization mafai faʻaleleia le vevela teteʻe ma masini meatotino o le mea, mafai foi ona faʻaaogaina e fesuiaʻi isi resins, faʻaaogaina e pei o pipiʻi, ufiufi, palasitika foam palasitika, faafoliga mea faʻasalalau, ma isi.

(4) TA o se lelei transmittance mea ma maualuga transmittance ma lelei transparency.

PTFE

Poly Tetra fluoroethylene (PTFE), e masani ona lauiloa o le “non-stick coating” pe “faigofie ona faʻamama mea”. O lenei mea ei ai uiga o le teteʻe i le acid ma alkali, teteʻe atu i soli eseese o vailaʻau ma vevela maualuga.

Tetee vevela maualuga: umi faʻaaogaina vevela o 200 ~ 260 tikeri;

Maualuga le teteʻe ile vevela: e malu pea ile -100 tikeri;

Faʻaleagaina oona: mafai i le aqua regia ma faʻamaʻoti uma meaola;

Tau tetee: o le sili soifua matutua olaga o uga;

Sili lubrication: le maualalo vaʻavaʻa coefficient o uga (0.04);

Nonviscous: maua le laʻititi laʻasaga feteʻenaʻi o se mea mautu e aunoa ma le tausisi i soʻo se vailaʻau;

Lē oona: faʻaletino tino; Lelei tele le faʻatinoina o le eletise, o le lelei C vasega faʻamama mea, o se mafiafia vaega o nusipepa mafai poloka 1500V maualuga voltage; E lamolemole nai lo o le aisa.

Pe o se masani PCB mamanu, pe maualuga-taimi, maualuga-saosaoa PCB mamanu, o le filifiliga o substrate o se taua malamalamaaga, tatou manaʻomia e pule. (PCB tuʻufaʻatasia).
