ʻO ka FR4 epoxy laminated sheet kahi mea i hoʻohana nui ʻia i ka ʻoihana uila ma muli o kāna mau pono uila a me nā ʻenehana. He ʻano mea i haku ʻia me ka lole fiberglass i ulana ʻia me kahi mea hoʻopili epoxy resin. ʻO ka hui pū ʻana o kēia mau mea i loaʻa i kahi lau a me ka lōʻihi i kūpono no ka nui o nā noi uila.

ʻO kekahi o nā mea hoʻohana mua o FR4 epoxy laminated sheets i ka ʻoihana uila no ka hana ʻana i nā papa kaapuni paʻi (PCB). ʻO nā PCB nā ʻāpana koʻikoʻi i loko o nā mea uila a pau, e lawelawe ana ma ke ʻano he kahua no ka hoʻopili ʻana a me ke kākoʻo ʻana i nā ʻāpana uila. Hāʻawi nā laminates FR4 i kahi substrate kūpono no nā PCB ma muli o ko lākou ikaika mechanical kiʻekiʻe, kūlana kūpaʻa maikaʻi, a me nā waiwai insulation uila maikaʻi. Hana kēia mau hiʻohiʻona i nā laminates FR4 i kūpono no ke kū ʻana i nā koʻikoʻi o ke kaiapuni uila me ka hāʻawi ʻana i kahi kahua hilinaʻi no nā kaʻa uila.

Ma kahi o nā PCB, hoʻohana pū ʻia nā laminates FR4 i ke kūkulu ʻana i nā mea insulating uila. ʻO nā waiwai insulation uila kiʻekiʻe o FR4 e lilo ia i koho kūpono no nā noi kahi e koʻikoʻi ai ka insulation uila. No ka laʻana, hoʻohana ʻia nā laminates FR4 i ka hana ʻana i nā pale insulating, busbars, a me nā mea ʻē aʻe i nā lako uila. ʻO ka hiki i ka mea ke kū i nā volta kiʻekiʻe a hāʻawi i ka insulation hilinaʻi he mea nui ia i ka ʻoihana uila.

Eia kekahi, hoʻohana ʻia nā laminates FR4 i ka hana ʻana i nā pā uila a me nā hale. Hoʻolālā ʻia kēia mau pā e pale i nā ʻāpana uila mai nā mea kūlohelohe e like me ka makū, ka lepo, a me ka pōʻino mechanical. Hāʻawi ʻo FR4 laminates i ke kūpaʻa maikaʻi loa i ka makū a me nā kemika, e kūpono ana iā lākou no ka hoʻohana ʻana i nā wahi paʻakikī. ʻO ka ikaika hopena kiʻekiʻe o ka mea a me nā waiwai pale ahi e kōkua pū i kona pono i ka pale ʻana i nā lako uila.

Eia kekahi, ʻike nā laminates FR4 i ka noi i nā mea hoʻololi uila a me nā mea hoʻololi. Pono kēia mau ʻāpana i nā mea hiki ke kū i nā wela kiʻekiʻe a hāʻawi i ka insulation uila maikaʻi loa. Hoʻokō nā laminates FR4 i kēia mau koi, e hoʻolilo iā lākou i koho koho no ka hoʻokaʻawale ʻana i nā ʻāpana i loko o nā transformers a me nā mea hoʻololi. ʻO ke kūpaʻa wela o ka mea a me ke kūpaʻa ʻana i ka arcing uila e kūpono ia no kēia mau noi koʻikoʻi.

Ma ke aupuni o nā kaʻa uila a me nā mea hana, hoʻohana ʻia nā laminates FR4 i ka hana ʻana i nā ʻāpana insulation e like me nā wedges slot, separators phase, a me nā laminations hope. He kuleana koʻikoʻi kēia mau ʻāpana i ka mālama ʻana i ka pono a me ka hana o nā mīkini uila. ʻO ka ikaika mechanical kiʻekiʻe a me ke kūpaʻa wela o FR4 laminates e hoʻolilo iā lākou i koho kūpono no kēia mau noi, e hōʻoiaʻiʻo ana i ka hana pono o nā kaʻa a me nā mea hana.
