Yintoni umahluko phakathi Ibhodi ye-FR4 epoxy fiberglass kwaye 3240 epoxy fiberglass ibhodi?

Ibhodi ye-epoxy fiberglass yasekhaya idla ngokuba yi-3240, kwaye Ibhodi ye-FR4 epoxy fiberglass idla ngokuthengwa kumazwe angaphandle. Kodwa zombini zizinto ezihluke kakhulu kwiimpawu ezibonakalayo okanye iimpawu zekhemikhali. Makhe ndiyazise kumntu wonke ngokufutshane:

1, 3240 epoxy glass fiberboard, igama elipheleleyo jikelele: 3240 epoxy phenolic fiberglass ilaphu ilaphu. Isebenzisa iglue epoxy resin kunye nephenolic imathiriyeli njengearhente yokunyanga. Iqondo lobushushu lidla ngokuba ngama-155 degrees. Ukusebenza kakuhle komatshini. Kwakhona kufanelekile kakhulu kwi-transformer kunye neoli ye-transformer. Ukuxinana ngokubanzi akugqithi kumgangatho wesizwe: 1.9.

Nangona kunjalo, abaninzi abavelisi basekhaya ngoku bathatha inxaxheba kwiifayili, ezifana ne-talcum powder, ukwenzela ukugcina iindleko kwinkqubo yokuvelisa. Ukuxinana kwabo kuye kwanda kakhulu. Kwakhona kunciphisa kakhulu ukusebenza kombane. Ifanelekile kuphela kwiiprojekthi zokugquma ngokubanzi.

2. FR4 epoxy glass fiber board. Kusetyenziswa iglue epoxy. Kodwa akusiyo i-ejenti yokunyanga enezixhobo ze-phenolic. Unyangwa ngokufanelekileyo kwiqondo lokushisa eliphezulu. Ithelekiswa neplastiki ecocekileyo. Iqondo lobushushu lidla ngokuba likhulu kune 180 degrees. Ukusebenza komatshini kunamandla kakhulu. Umntu osebenza naye wakhe waqhula ukuba ukusika ngomatshini wokusika kusika iintlantsi.

ibonisa ukusebenza kwayo. Kwaye ayiyi kuqhekeka okanye idibanise xa isetyenziswa. Ukusebenza kombane kunamandla kakhulu. Ifanelekile kwiibhodi zeesekethe ze-elektroniki kunye ne-laminates zobhedu. Imathiriyeli esisiseko inokuba lilaphu elicolekileyo lonke. Ilaphu le-fiber ye-elektroniki. Ngokuqhelekileyo kubuninzi be-1.85. Ukumelana nokubola kweekhemikhali.

Ibhodi ye-epoxy fiberglass ye-3240 kunye nebhodi ye-FR4 epoxy fiberglass zezona zixhaphakileyo iibhodi ze-epoxy fiberglass ngoku kwimarike. Wonke umntu uthi iFR4 ingcono kuno-3240. Yintoni umahluko phakathi kwabo?

Umahluko 1: i-FR4 inentsebenzo entle yedangatye.

I-FR4 yimveliso ephuculweyo ye-3240 epoxy glass fiber board. Ukusebenza kwe-flame retardant ye-FR4 epoxy glass fiber board idibana nomgangatho wesizwe we-UL94V-0. Ibhodi ye-epoxy yeglasi ye-epoxy ayinayo iipropathi zokubuyiswa komlilo.

Umahluko 2: Umbala oguqukayo.

Umbala we-FR4 uyinto yendalo kakhulu, i-jade encinci, kwaye umbala webhodi ye-3240 epoxy fiberglass yibhodi encinci yokuqhwanyaza. Ayibonakali yendalo kakhulu. Uninzi lwemibala alufani kakhulu.

Umahluko wesithathu: I-FR4 ayinamitha kwaye ihambelana nokusingqongileyo.

Ibhodi yefiber yeglasi ye-3240 ye-epoxy iqulethe i-halogen, engahambelani kakhulu nokusingqongileyo kunye nomzimba womntu. Kananjalo ayihambelani nesicwangciso selizwe sophuhliso oluzinzileyo lohlaza. I-FR4 epoxy glass fiber board ichasene nje.

Umahluko 4: i-FR4 inokuzinza okuhle.

I-FR4 inozinzo olungcono lwe-dimensional kune-3240, kwaye ngexesha lenkqubo yokucinezela, ukunyamezela kobunzima be-FR4 nako kungcono kakhulu kune-3240, efanelekileyo ngakumbi ukusetyenzwa.

Umahluko wesihlanu: i-FR4 inokucima umlilo.

I-FR4 inokucinywa ngokwendalo xa kuvele umlilo.

Umahluko ezintandathu: ukufunxa amanzi aphantsi.

Ukufunxwa kwamanzi (D-24/23, ubukhulu beplate 1.6mm): ≤19mg, ebonelela ngoncedo olufanelekileyo ekusetyenzisweni kwayo kwisiguquli esimanzi nakwezinye izixhobo.

Ngenxa yokuba i-FR-4 epoxy glass fiber board inomsebenzi omhle kakhulu, ngoku isetyenziswa njengesixhobo sokugquma iindawo kumashishini ombane nawe-elektroniki. Ewe kunjalo, ibhodi ye-3240 epoxy fiberglass isenayo imarike ethile ngenxa yenzuzo yayo yexabiso.
