Yintoni i-fr4 i-fr4 sheet?

Ngaba loluphi uhlobo lwezinto eziluFr4? Zithini iimpawu zayo kunye nokusetyenziswa?

Iphepha le-FR4 ye-FR4 luhlobo olunye lwephepha le-EPOXY, "Fr" sisifinyezo "sedangatye", kunye nephepha le-Fr4 yi-flament yeflethi ehlawula "i-Fr4". Iphepha le-FR4 i-FR4 Iphepha lishushu kunye nokufuma okunganyangekiyo, ukuthambisa kunye nelangatye, kwaye linezinto ezilungileyo zendlela kunye ne-diectric. Ubushushu kunye nokunganyangeki komswakama, i-insular kunye nelangatye, kwaye ineepropathi ezihamba kakuhle kunye neeplanga zesekethe, eziqhele ukusetyenziswa kwiibhodi zesekethe, iindidi kunye neminye imveliso.

Yintoni iphepha le-Fr4?

Iphepha le-FR4 i-FR4 iluhlobo lwephepha le-EPOXY (i-EPOXY STATE), esona sixhobo sokuhlanganisa okwenziwe nge-Epoxy Retin, i-polymer ye-polymer ye-polymer, kunye ne-fiber yeglasi. I "Fr" sisishwankathelo sesiNgesi "sedangatye", kwaye iphepha le-Fr4 lihambelane nenqanaba "Fr4" lebakala elihlawulelwayo.

Kukho imibala emininzi yephepha le-FR4, enjengamhlophe, emnyama, eluhlaza, iblowu, njalo njalo.

Zithini iipropathi zephepha le-FR-4 Epoxy?

Kutheni usithi iBhodi ye-Fr-4 iBhodi ye-Eposm Epoxy esebenzisa i-Fr4 iBhodi, ikwabizwa ngokuba yiBhodi ye-Eposm, ikwalula iBhodi ye-Epoxy, iBhodi ye-Epoxy i-EPOXY inokusikwa ngokwahlukileyo I-SIRICS ngokweemfuno zabathengi, kwaye ineepropathi eziphakamileyo zoomatshini kunye neepropathi zeDeectric: Abathengisi beBhodi yeBhodi, ubushushu obuhle kunye nokunganyangeki komswakama, kunye noomatshini bokungasebenzi kakuhle.

IBhodi ye-FR-4 iBhodi ye-Epoxy inoluhlu olubanzi lokusetyenziswa, kubandakanya i-coptors yombane` izixhobo zombane zokufaka izilwanyana, kubandakanya iindidi zesekethe ezishicilelweyo, i-proble yombane `ye-probssing, njl. Isakhelo) kwaye sinokusetyenziswa kwiimeko ezinomswakamo kunye neoyile yotshintsho.

Iimpawu ezahlukeneyo zeBhodi ye-Epoxy:

1.iifomu ezahlukeneyo ezahlukeneyo. Iindidi ezahlukeneyo zamachiza, ukunyangwa kwearhente, inkqubo yomculo ngokusisiseko ikwazi ukuziqhelanisa neemfuno zezicelo ezahlukeneyo kwifomu echaziweyo.

I-2.strong enencasa. I-epoxy rensin ye-molecular thein kwimvelaphi ye-hydroxyl kunye ne-ether ye-ether ekhoyo ukuze inamathele kakhulu kwiindidi ezahlukeneyo zezinto.

Iipropathi ze-3.Mechacal. Inkqubo enyangeke ye-Epoxy ineepropathi ezintle zoomatshini.

4.Ukuhlala i-shrintage. I-Epoxy Retin kunye nokusabela kwi-Arhente yokuThumela isetyenziselwa ukuphendula ngokuthe ngqo okanye i-epoxy reamsin molecule yokuphendula nge-Polymerization yokuphelisa ukungabikho kwamanzi okanye ezinye iimveliso eziguqukayo zikhutshiwe.

5.Izakhiwo zepropathi. Inkqubo ephilisiweyo ye-Epoxy i-Epoxy Systen yinto elungileyo yokufaka i-properries ephezulu yokuphambuka, ukumelana nokuvuza komgangatho, ukuxhathisa i-ARC.

6.Umdanisela. Ukusetyenziswa kweendidi ezahlukeneyo ze-Eposer ye-Epose ye-Epose ye-Eposey ye-Eposey ye-Eposey kunokunyangeka kuluhlu lobushushu lwe-0-180 ℃.

7. I-7.CHICALY uzinzo. Inkqubo ephithileyo ye-Epoxy Realsin inayo i-Alokali elungileyo, ukunganyangeki kwe-Acid kunye nokunganyangeki kwesilivere. Njengokunyanga inkqubo ye-EPOXY ye-EPOXY yezinye iimpawu ezifanayo, uzinzo lwamachiza lixhomekeke kwi-resen kunye ne-arhente yokunyanga. Ukusetyenziswa ngokuphakathi kwe-Epoxy Reward kunye neearhente zokunyanga, zinokwenza ikwazi ukusebenza ngokukhethekileyo kwimichiza.

8. Uzinzo lozinzo. Ukudityaniswa kweempawu ezininzi ezilapha ngasentla kwenkqubo ye-epoxy resin ineendlela zokuzinza kunye nokuqina.

Ukumelana nokubumba. Inkqubo ye-Epoxy ye-Epoxy inyangeka ixhaphakile kukubumba kakhulu kwaye inokusetyenziswa kwiimeko ezinomsindo.

2.Ukusebenzisa i-FR4 iphepha

Iphepha le-FR4 linoluhlu olubanzi lokusebenzisa, ikakhulu isetyenziswa kwi-elektroniki, ngombane, unxibelelwano, i-aerospace kunye namanye amasimi. Oku kulandelayo luphantsi lwayo oluphambili:

1. Iibhodi zesekethe

Kwimveliso ye-elektroniki, iphepha le-Fr4 lidla ngokusetyenziswa ekwenziweni kweebhodi zebhokisi. Ingasetyenziselwa njengezinto ezibalulekileyo kwiibhodi zesekethe zokuqinisekisa uzinzo kunye nokuthembeka kweebhodi zesekethe.

2. Isithuba kunye nempahla yodwa

Iphepha le-FR4 i-FR4 linezinto ezinqamlezileyo kunye nozinzo lobushushu obuphezulu, ukuze zisetyenziswe njenge-bulkkhead kunye nezinto zodwa kwinkqubo yamandla. Oku akuqinisekisi kuphela ukhuseleko lombane kwezixhobo, kodwa kukuthintela iingqondo ezenziwe ziimpazamo zombane.

3. Inxalenye yoomatshini

Iphepha le-FR4 lingasetyenziswa njengesixhobo sezinto zoomatshini, ezinje ngezixhobo zeZixhobo zoMatshini kunye ne-Injini ye-Injini yemoto. Inepropathi egqwesileyo kunye nokuzinza kwemichiza, kwaye inokusetyenziswa kwiinkqubo ezahlukeneyo zoomatshini.

Ukuqukumbela, iphepha le-Fr4, njengezinto ezibalulekileyo zombane ezineepropathi zombane ezibalaseleyo, ukomelela koomatshini kunye nokuzinza komhlaba, kusetyenziswa ngokubanzi kwi-aerospace, unxibelelwano, umbane kunye namanye amasimi. Amashishini okufana elenziwe nge-elektroniki, akhetha iphepha eliphezulu le-FR4 angabanceda baphucule umgangatho wemveliso kunye nokhuphiswano lwentengiso.
