He aha ka ʻokoʻa ma waena o FR4 Epoxy Fiberglass Sheet a me 3240 Epoxy Resin Sheet?

2021-03-21

  elua 3240 Epoxy Resin Pepa a FR4 Epoxy Fiberglass Pepa ua hana ʻia me ka lole alkali-free E-aniani i hoʻopili ʻia me ka epoxy resin ma ka hana ʻana ma lalo o ka wela a me ke kaomi, nona ka ikaika mechanical kiʻekiʻe loa, Insulation, pale ʻana i ka wela, nā waiwai uila a me nā waiwai kūpaʻa maikaʻi. Akā ʻokoʻa loa kēia mau mea ʻelua ma ke ʻano o nā waiwai kino a i ʻole nā ​​​​mea kemika.

 

  Hoʻohana ʻia ka paʻa o 3240 Epoxy Sheet epoxy resin, me ka resin phenolic e like me ka mea hoʻōla. ʻO ke kūpaʻa wela kiʻekiʻe he 155 degere. He machinability maikaʻi, kūpono loa no nā mea hoʻololi a me ka ʻaila transformer. ʻAʻole ʻoi aku ka nui ma mua o ka pae aupuni: 1.9. Akā i kēia manawa ua hoʻohui nā mea hana Kina i nā mea hoʻopihapiha e like me ka pauka talcum e mālama i nā kumukūʻai i ka hana hana. Ua hoʻonui nui ʻia kona mānoanoa. Akā hoʻemi nui ia i kāna hana uila, hiki ke hoʻohana wale ʻia i ka ʻenehana insulation maʻamau.

  Hoʻohana pū ka FR4 Epoxy Fiberglass Laminate Sheet i ka epoxy glue. Eia naʻe, ʻaʻole ia e hoʻohana i ka resin phenolic ma ke ʻano he lāʻau lapaʻau. Ho'ōla loa ia ma nā wela kiʻekiʻe, maʻamau 180 degere a ʻoi aku paha. Loaʻa iā ia ka mechanic kiʻekiʻe a me ka dielectric hana, pili ʻia e like me nā ʻāpana hana insulation no nā mea electromechanical/electrical, a hoʻohana ʻia ma lalo o nā kūlana kūlohelohe a me ka ʻaila o ka transformer. A hiki iā ia ke kū i nā ʻano mea hoʻoheheʻe kemika a me ka ʻakika waika. Eia kekahi, kūpono ʻo FR4 no nā papa kaapuni uila a me ka laminate keleawe.

  ʻO nā plastics HongDa he plastic laminated ʻoihana i hana ʻia me ka resin-based thermoset material i hoʻoikaika ʻia me ka fiberglass, ka lole pulupulu, ka pepa. He ikaika maikaʻi loa ka Hongda laminates, a ʻo ke kūpaʻa ikaika i ka wela, ke koʻikoʻi a me kā mākou papa insulating e hoʻohālikelike ʻia me nā huahana like ma waho o ka hana a me ka maikaʻi. Ua makemake ʻia ka ʻoihana e nā ʻoihana kalepa ʻē aʻe, a ua lawe aku i kāna huahana i Russia, Middle East, India, Southeast Asia a me nā ʻāina ʻē aʻe a me nā ʻāina, a ʻoi aku ka nui o ka nui o nā mea kūʻai aku ma mua o 30% o ka huina kūʻai.
