PCB substrate kusarudzwa

Mafungiro ekutanga ekusarudza substrates tembiricha (kutenderera uye kushanda), magetsi zvivakwa, zvinowirirana (zvinhu zvekuwisira, zvinobatanidza), masimba echimiro uye kuwanda kwedunhu, nezvimwe, zvichiteverwa nezvinhu uye nekugadzirisa mutengo. Ndokumbira utarise kunhamba inotevera kuti uwane rumwe ruzivo:

Str Substrate sarudzo dhizaini (tsime: tsime “GJB 4057-2000 Yakadhindwa Circuit Bhodhi Dhizaini Zvinodikanwa zveMasoja emagetsi Midziyo”)

Kutsanangura zita

FR-4

Fr-4 irimi remoto risingadziviriri kirasi kodhi, iyo inomiririra zvinoreva resin zvinhu mushure mekutsva kwenyika inofanirwa kukwanisa kuzvidzimisa gadziriso yezvinhu, harisi zita rezvinhu, asi kirasi yezvinhu.

Tg / girazi kutendeuka tembiricha

Tg kukosha kunoreva tembiricha iyo iyo zvinhu zvinoshanduka kubva kune inoomesera girazi mamiriro kuenda kune yakasununguka uye inochinjika nyika yerabha. Ziva kuti zvinhu zvemidziyo zvinoshanduka pamusoro Tg.

CTI

CTI: Kuenzanisa Yekutevera Index, chidimbu cheKuenzanisa Yekutevera Index.

Zvinoreva: ndicho chiratidzo chekudonha kusagadzikana. Mumamiriro ekushandisa voltage kumeso kwechinhu ichivhara, ita madonhwe emagetsi kuwira pamusoro pechinhu chakaumbwa pakati pemagetsi, uye ongorora iwo magetsi kusvika pasisina kukuvara kwekudonha.

CTI nhanho: iyo CTI nhanho inosvika kubva pa0 kusvika pa5. Iyo diki iyo nhamba, iyo yepamusoro iyo yekudonha kuramba.

PI

Polyimide (PI) ndomumwe makemikari Polymer zvinhu pamwe yakanakisisa nzwisisika waivako.Kupisa kwaro kwepamusoro kupisa kusvika ku400 ℃ pamusoro, nguva refu yekushandisa tembiricha ye -200 ~ 300 ℃, chikamu chepo isina kunyungudika poindi, kuita kwakawanda kwekudzivirira, 103 hz dielectric inogara iri 4.0, dielectric kurasikirwa chete 0.004 ~ 0.007, iri F kuna H.

CE

(1) CE cyanate resin rudzi rutsva rwezvinhu zvemagetsi uye inodzivirira zvinhu, chinova chimwe chezvinhu zvakakosha zvakakosha mumunda wemagetsi zvigadzirwa uye microwave kutaurirana tekinoroji. Iyo yakanaka resin matrix zvinhu zveRadome. Nekuda kwekugadzikana kwayo kwakanaka kwekushisa uye kupisa kupisa, yakaderera mitsara yekuwedzera yekuwedzera uye zvimwe zvakanakira, CE resin rave rakanakisa matrix zvinhu zvekugadzirwa kweyepamusoro frequency, kuita kwepamusoro, mhando yepamusoro yemagetsi yakadhindwa wedunhu mabhodhi; Uye zvakare, CE resin yakanaka chip chip kurongedza zvinhu.

(2) CE nebwe inogona kushandiswa kugadzirwa kwemauto, avhiyesheni, Aerospace, Navigation STRUCTURAL zvikamu, zvakadai mapapiro, ngarava anoshongwa, etc., asiwo zvinogona kuitwa Aerospace furo sangweji STRUCTURAL zvinhu inowanzoshandiswa.

(3) CE nebwe rine kugarisana zvakanaka, uye epoxy nebwe, unsaturated polyester uye mamwe copolymerization anogona kuvandudza kupisa nemishonga uye zvemaziso ehupfumi ari zvinhu, rinogonawo kushandiswa kugadzirisa dzimwe Inogadzirwa nemasiridzi anobuda mumiti, anoshandiswa seanosungira, machira, anoumba furo mapurasitiki, chakagadzirwa midhiya zvinhu, nezvimwe.

(4) CE chishandiso chakanaka chekutumira chakakwira kutumira uye kujekesa kwakanaka.

PTFE

Poly Tetra fluoroethylene (PTFE), inowanzozivikanwa se “isina-tambo inonamira” kana “iri nyore kuchenesa zvinhu”. Ichi chinyorwa chine hunhu hweacid uye alkali kuramba, kuramba kune akasiyana organic manyoro uye yakanyanya tembiricha.

High tembiricha nemishonga: -refu kushandiswa tembiricha 200 ~ 260 madhigirii;

Low tembiricha kuramba: ichiri yakapfava pa -100 madigiri;

Corrosion kuramba: inokwanisa ku aqua regia uye ese manyoro solvents;

Kuramba kwemamiriro ekunze: hwakanakisa hupenyu hwekukwegura hwepurasitiki;

Kukwidziridzwa kwepamusoro: iyo yakaderera kukakavara koefficient yepurasitiki (0.04);

Nonviscous: kuve nekadiki padiki kukakavara kwechinhu chakasimba pasina kuomerera kune chero chinhu.

Isiri-chepfu: mumuviri inert; Kwakanaka mashandiro emagetsi, ndiyo yakanaka C kirasi kuputira zvinhu, rakakora denderedzwa repepanhau rinogona kuvhara 1500V yakakwira voltage; Yakatsetseka kupfuura chando.

Kunyangwe iri yakajairika pcb dhizaini, kana yakakwira-frequency, yakakwira-inomhanya pcb dhizaini, sarudzo yeiyo substrate ruzivo rwakakosha, tinofanirwa kugona. (Yakabatanidzwa pcb).
