Farqiga iyo codsiga substrate aluminium iyo guddiga fiber galaas

1. Fiberglass board (FR4, hal dhinac ah, laba-dhinac, multilayer PCB circuit board, impedance board, indho la'aan lagu aasay looxa), ku haboon kombiyuutarada, telefoonada gacanta iyo alaabta kale ee digital digital.

Waxaa jira siyaabo badan oo loogu yeero guddiga fiberglass-ka, aan marka hore si wadajir ah u fahanno; FR-4 waxaa sidoo kale loo yaqaannaa looxa fiberglass; looxa fiberglass; FR4 guddiga xoojinta; FR-4 looxa resin epoxy; looxa dahaarka ololka; epoxy Board, guddiga iftiinka FR4; guddiga maro galaas epoxy; guddiga dib u qodista guddiga wareegga, guud ahaan loo isticmaalo lakabka saldhigga xirmo jilicsan, ka dibna lagu daboolay dhar iyo maqaar si loo qurxiyo derbiga iyo saqafka quruxda badan. Codsigu aad buu u ballaadhan yahay. Waxay leedahay sifooyinka nuugista dhawaaqa, dahaarka dhawaaqa, kulaylka dahaarka, ilaalinta deegaanka, iyo ololka dib u dhiga.

Looxa fiber-ka galaasku waa walxo isku dhafan oo ka samaysan resin epoxy, filler (Filler) iyo fiber galaas ah.

Tilmaamaha ugu muhiimsan ee farsamada iyo codsiga guddiga iftiinka FR4: waxqabadka dahaarka korantada xasilloon, fidsanaanta wanaagsan, dusha siman, godad la'aan, dulqaadka dhumucdiisu ka badan tahay heerka, oo ku habboon alaabooyinka leh shuruudaha dahaarka elektaroonigga ah ee waxqabadka sare leh, sida guddiga xoojinta FPC, iska caabinta foornada daasadda Taarikada heerkulka sare, diaphragms kaarboon, maraakiibta saxda ah, xirmooyinka tijaabada PCB, korantada (korontada) qaybaha dahaarka qalabka, taarikada dahaarka, qaybaha dahaarka transformer, qaybaha mootooyinka, alwaaxyada terminalka gariiradda leexinta, looxyada daboolka wareejinta elektiroonigga ah, iwm.

Looxa fiberglass-ka waxaa inta badan loo isticmaalaa korantada caadiga ah, elektiroonigga ah iyo alaabada dhijitaalka ah sababtoo ah sifooyinka wanaagsan ee alaabta. Qiimuhu wuu ka sarreeyaa kan warqadda iyo fiber-glass-ka yar, iyo qiimaha gaarka ah wuxuu ku kala duwan yahay shuruudaha badeecadaha kala duwan. Board fiberglass sidoo kale si weyn ayaa loo isticmaalaa in alaabta elektarooniga ah digital.

Sababtoo ah faa'iidooyinka gaarka ah ee guddiga fiberglass-ka, waxaa si ballaaran loo isticmaalaa soosaarayaasha elektiroonigga ah. Looxa looxa fiberglassku wuxuu leeyahay godadka V, godadka shaambada, buundooyinka iyo noocyada kale ee hababka fuulitaanka.

Marka labaad, substrate aluminium (aluminium aluminium ah oo hal dhinac ah, aluminium aluminium ah oo laba-gees ah), substrate aluminium inta badan wuxuu leeyahay waxqabadka kuleylka heersare ah, oo ku habboon tignoolajiyada LED, saxanka hoose waa aluminium.

Substrate-ka aluminiumku waa laminate naxaas ah oo ku salaysan bir oo leh shaqo kuleyl wanaagsan. Guud ahaan, looxa hal dhinac ah wuxuu ka kooban yahay qaab-dhismeed saddex-lakab ah, kaas oo ah lakabka wareegga (foil naxaas ah), lakabka daboolka iyo lakabka saldhigga birta. Isticmaalka-dhamaadka sare, waxaa sidoo kale loogu talagalay sidii guddi laba-geesood ah, iyo qaab-dhismeedku waa lakabka wareegga, lakabka daboolka, saldhigga aluminium, lakabka daboolka, iyo lakabka wareegga. Codsiyo aad u yar ayaa ah loox-lakabyo badan, kuwaas oo lagu samayn karo iyada oo la isku xidho loox-lakabyo badan oo caadi ah oo leh lakabyo dahaar ah iyo saldhigyo aluminium ah.

Substrate-ka aluminiumku waa nooc ka mid ah PCB. Substrate-ka aluminiumku waa loox daabacan oo bir ku salaysan oo leh kulayl sare. Guud ahaan waxaa loo isticmaalaa alaabooyinka u baahan kala daadinta kulaylka sida tamarta qorraxda iyo nalalka LED. Si kastaba ha ahaatee, walxaha guddiga wareegga waa aluminium aluminium. Waagii hore, guddiga wareegga guud ee alaabta loo isticmaalo waa fiber galaas ah, laakiin sababtoo ah LED-ku wuu kululeeyaa, guddiga wareegga ee nalalka LED guud ahaan waa substrate aluminium ah, kaas oo si dhakhso ah u dhaqi kara kulaylka. Qalabka wareegga ee qalabka kale ama qalabka korontada weli waa loox fiberglass ah!

Inta badan aluminiumka LED-yada waxaa guud ahaan loo isticmaalaa nalalka tamarta-badbaadinta LED-ka, sidoo kale TV-yada LED-yada ayaa sidoo kale loo isticmaali doonaa, inta badan walxaha u baahan kulaylka, sababtoo ah inta badan LED-ga hadda, iftiinka iftiinka, laakiin waxay ka baqaysaa sare. heerkulka iyo heerkulka xad dhaafka ah. Ka baxsan kuulka laambada, waxaa jira suus fudud iyo wixii la mid ah.

Isticmaalka ugu muhiimsan ee aluminiumka aluminiumka iyo aluminiumka aluminiumka LED:

1. Qalabka maqalka ah: cod-weyneyaasha wax-soo-gelinta iyo soo-saarka, cod-weyneyaal dheellitiran, cod-weyneeyeyaal, hor-u-qaadayaal, cod-weynayaal, iwm.

2. Qalabka korantada: maamulaha beddelka, beddelka DC/AC, SW regulator, iwm.

3. Isgaadhsiinta iyo qalabka elegtarooniga ah: cod-weyneeye-soo noqnoqda sare-sare ee wareegga gudbinta korantada.

4. Qalabka iswada ee xafiiska: matoorada, iwm.

5. Baabuurka: nidaamiyaha elektarooniga ah, dab-damiya, kontaroolka, iwm.

6. Kumbuyuutar: guddiga CPU, diskooga floppy-ka, aaladda korontada, iwm.

7. Module korantada: buundada toosiye 'soo gudbinta adag', iwm.

8. Laambadaha iyo Laambadaha: Horumarinta iyo kor u qaadida nalalka tamarta-badbaadinta, nalalka kala duwan ee tamarta badbaadinta iyo nalalka LED-yada ayaa caan ka noqday suuqa, sidoo kale qalabka aluminium ee loo isticmaalo nalalka LED ayaa sidoo kale bilaabay in lagu dhejiyo si ballaaran. .
