Mene ne bambanci tsakanin da yawa zanen gado na gilashin fiber allo, epoxy jirgin da FR4 jirgin
1. Amfani daban-daban.Babban albarkatun kasa don samar da allunan kewayawa sune zanen gilashi marasa alkali, takarda fiber, da resin epoxy.Gilashin fiber allo: substrate fiberglass zane, epoxy allo: m ne epoxy guduro, FR4: substrate auduga fiber takarda.Duk ukun allunan fiberglass ne.
2. Launuka daban-daban.Yawanci allon epoxy akan kasuwa shine phenolic epoxy, rawaya.Ba don ƙaƙƙarfan madaurin allon kewayawa ba, dalilai na rufe wutar lantarki.FR4 takardar epoxy ce mai tsafta na daidaitattun NEMA, launi na yau da kullun shine duhu kore, wanda shine launi na epoxy.Akwai kuma masu rawaya.Gabaɗaya magana, rawaya FR4 ana kiransa kayan rawaya, kuma fari (kore) ana kiransa fari abu.FR4 ya fi tsada fiye da allon epoxy, kuma allon fiber gilashi ba zai iya tabbatar da farashin ba.

Kwamitin Epoxy da allon fiber gilashi sun ƙunshi ƙungiyoyin epoxy masu aiki a cikin tsarin ƙwayoyin cuta, waɗanda zasu iya haye-haɗe tare da nau'ikan nau'ikan magunguna daban-daban don samar da polymers waɗanda ba za su iya narkewa ba tare da tsarin hanyar sadarwa ta hanyoyi uku.
Da farko, cikin sharuddan abun da ke ciki, babban albarkatun kasa don samar da kewaye allon ne alkali-free gilashin zane, fiber takarda, epoxy guduro.
Fiberglass allo: Substrate fiberglass zane
Al'adar Epoxy: Adhesive shine resin epoxy
FR 4: Base abu auduga fiber takarda
A takaice dai, allunan epoxy a kasuwa yawanci epoxy phenolic ne, mai launin rawaya, wanda galibi ba a yi amfani da shi azaman juzu'i don allunan da'ira mai wuya ba, amma don dalilai na rufin lantarki.
FR4 shine NEMA daidaitaccen takaddar epoxy mai tsafta, launi na yau da kullun yakamata ya zama kore mai duhu, wanda shine launi na epoxy.Akwai kuma masu rawaya.Gabaɗaya magana, rawaya FR4 ana kiransa kayan rawaya, kuma fari (kore) ana kiransa fari abu.
