Ka kooban badeecada

Qalabka isku-dhafka ah ee loo yaqaan 'epoxy resin' iyo dhalada dhalada ayaa si ballaaran loogu isticmaalaa elektiroonigga, korantada, isgaarsiinta iyo meelaha kale ee ay sabab u tahay guryaha korantada ee aadka u fiican, xoogga makaanikada iyo iska caabbinta kuleylka. "FR" ee FR4 waxay u taagan tahay "ololaynta ololka", taasoo muujineysa inay leedahay guryo dib u dhac ah oo wanaagsan.

Astaamaha waxqabadka

Xoog sare: saxanka fiberka ee ephoxy ah ayaa muujinaya lebis iyo xoog sare, oo ku habboon qaab-dhismeedka kala duwan ee kala duwan.

Iska caabbinta qaddarka: Hababkeeda kiimikaadkeeda ee gaarka ah awgeed, saxanka ayaa aad u adkaysata aashitada, alkalis, iyo kiimikooyinka kale.

Biyo-celintu

Kastaarka korantada

Guryaha korantada ee xasilloon: Waxqabadka korantada ayaa wali deggan heerkulka sare, iyadoo la hubinayo in hawlgalka jilicsan ee qalabka.

Istaraaca kuleylka iyo qoyaanka ah: Plate-ka Fiberglass ee Epoxy wuxuu ku hayaa wax qabad wanaagsan heerkulka sare iyo huurka.

Wax-ka-qabashada wanaagsan

Faa'iidooyinka

Waxqabadka Sare: Guryaha korantada ee aadka u wanaagsan iyo astaamaha farsamada, oo ku habboon dalbashada codsiyada.

Dib-u-dhigista ololka: Wuxuu la kulmaa heerar adag oo olol ah oo ololaya oo aad u nabad qabata.

Ruuxitaan: ku habboon codsiyo kala duwan oo elektiroonig ah iyo koronto.

Wax-ka-qabashada: Way fududahay in la gooyo, qoditaanka iyo dusha sare ee daweynta.

Badbaadinta Deegaanka: Alaabada qaarkood waxay u hoggaansamaan heerarka ilaalinta deegaanka sida Rohs.

Goobaha Codsiga

Waxsoosaarka PCB: FR4 waa maaddada ugu weyn ee wax soo saarka loosoosaar boodhka la daabacay (PCBBs) waxaana si weyn loogu isticmaalaa aaladda elektiroonigga ah.

Dambiilaadda korantada: Waxaa loo isticmaalaa in lagu qaybiyo qaybaha qalabka korantada sida transformersers, Relays, beddelaadda, iwm.

Qalabka isgaarsiinta: Waxaa loo isticmaalaa qalabka isgaarsiinta sare sida anteenooyinka iyo miirayaasha.

Xakamaynta Warshadaha: Waxaa loo isticmaalaa golayaasha wareega iyo qaybaha kharashka ku jira nidaamyada xakamaynta warshadaha.

Elektaroonigyada baabuurta: Waxaa loo isticmaalaa unugyada xakamaynta baabuurta (ECUS) iyo dareemayaasha, iwm.

Aerospace: Waxaa loo isticmaalaa in looxyada wareejinta waxqabadka sare ee qalabka elektaroonigga ah.

Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.

Warqad maqas

1.Q: Waa maxay waxqabadka korantada korantada ee looxyada FR4? Miyey ku habboon tahay wareegga soo noqnoqda ee soo noqnoqda?

A: FR4 waxay leedahay iska caabin sare (> 10¹⁴¹⁴ ω ω ω · cm) iyo dieltric xasilloon oo deggan (4.2-4.7 @ 1.ghz). Khasaaraha soo noqnoqda ee sareeya ayaa ah 10% wax ka yar tii ay ka mid tahay kuwa alsuminium subterates, taasoo ka dhigaysa doorashada ugu habboon qalabka isgaarsiinta.

2.Q: Waa maxay faa'iidooyinka xoogga farsamo ee FR4 marka la barbar dhigo sunta aluminium?

A: fr4 wuxuu leeyahay awood dabacsan oo ah 200 milyan oo ah 150 MPA illaa 150 MPA oo loogu talagalay sunta aluminium), 30% iska caabin saamayn badan leh, iyo qaab dhismeedka badan ee musuqmaasuqa badan, taasoo ka dhigeysa inay ku habboon tahay deegaannada gariirka warshadaha.

3.Q: Dulquile fr4 u adkaysata ku filan ee loogu talagalay iibinta rasaasta-bilaashka ah?

A: Haa! FR4 waxay leedahay iska caabbinta qandho oo ah 130-180 ° C (noocyada sare ee TG) oo ay u adkeysan karaan dib-u-celinta iibinta 288 ° C muddo gaaban. Substrates caadiga ah (sida 3240) kaliya ayaa u adkeysaneysa 130 ° C oo u nugul inay tirtiraan.

4.Q: Dib-u-dhackeeda ololka ah ma laqabeysaa heerarka badbaadada?

A: Ul94 V-0 Shahaadadaada, is-deminta 10 ilbiriqsi gudahood iyo dhibic aan dhibic lahayn. Substrate-ka (FR-1) ma aha olol dib u dhac ah oo wuxuu xambaarsan yahay halis sare.

5.Q: Fr4 miyey ku guul darreysan doontaa bey'adda qoyan?

A: Isu nuugida biyuhu waa <0.1%, iyo iska caabinta qoyan ee qoyan waa xasilloon tahay. Guddiga fiberlass ee caadiga ah waxay leeyihiin xaddiga biyo-la'aanta ee ilaa 0.5%, oo si fudud u sababi kara wareegga gaagaaban.

6.Q: Sidee Qiimaha FR4 isbarbardhigayaa si loo sameeyo sunta 'walbaha'?

A: fr4 waa kaliya 1/10 qiimaha furitaanka dhoobada oo leh wax ka qabashada wax ka qabashada 98%. Substrates dhoobada waa jilicsan yihiin oo waxay leeyihiin 20% kharash qodista oo sarreeya.

7.Q: Maxaad u doorataa FR4 dusha Aluminium ee loogu talagalay ilaha nalka?

A: Subleration aluminium waxay leeyihiin ku-tuur kulul oo kuleyl ah, laakiin FR4 waa heerkul-lagu xakameyn karo (85 ° C) awooda <2w / cm² oo ay ka dhiman tahay 30%, oo ku habboon dhulalka korantada hooseeya.

8.Q: Miyuu Fr4 miyuu leeyahay xasillooni yar oo ka wanaagsan qalabka kale?

A: The Z-axis thermal expansion coefficient is only 49.7ppm/°C (compared to 64.5ppm for ordinary epoxy substrates), reducing deformation by 35% under temperature and humidity fluctuations, ensuring precision circuit accuracy.

9.Q: Ma loo isticmaali karaa jawiga adag sida elektiroonigga baabuurta?

A: Haa! Waxay u adkaysata hubka kiimikada iyo shoogga kuleylka (-40 ~ 125 ° C), oo leh nolol adeeg ah 15 sano. Subnates aluminium waxay u nugul yihiin oksidation ee jawiga aashitada-etching.

10.Q: Waa maxay sababta FR4 ka mid ah sunta sunta ah ee warshadaha PCB?

A: Waxay bixisaa qiimaha ugu wanaagsan ee waxtarka: 30% awooda ka sareeya sunta aluminium, 90% qiimo jaban oo ka hooseeya subterates-ka sareeya, oo ay si aad ah uga yaraato sunta 'competetes', oo daboolaya 90% ee codsiyada elektiroonigga ah.
