No ke aha e hoʻohana ai iā FR4 e hana i nā PCB Tg kiʻekiʻe?
Pono kekahi mau noi i ka PCB e kū i nā wela kiʻekiʻe o 200 ℃ a i ʻole.No ka hana hilinaʻi i nā noi wela kiʻekiʻe, pono mākou i nā PCB i hoʻolaʻa ʻia i hana ʻia me ka hoʻohana ʻana i nā mea i hoʻokō ʻia.Hoʻolālā ʻia kēia blog e hoʻomaʻamaʻa iā ʻoe me kahi PCB i hoʻolaʻa ʻia, i kapa ʻia ʻo HIGH-TG.ʻO kēia mau meakiʻekiʻe tg PCBshiki ke pale i nā mahana hoʻololi aniani kiʻekiʻe loa o nā PCB i ka hāʻawi ʻana i kēia mau hiʻohiʻona:
1. Hoʻonui i ka mana impedance
2. ʻOi aku ka maikaʻi o ka hoʻokele wela
3. Haʻahaʻa haʻahaʻa haʻahaʻa
4. Hana mau
FR4 — Mea makemake ʻia no nā PCB Tg kiʻekiʻe
No nā noi kiʻekiʻe wela, hana ʻia nā PCB Tg kiʻekiʻe me ka hoʻohana ʻana i nā substrates FR-4.ʻO Fr-4 kahi mea epoxy i hoʻopaʻa ʻia i ka lapalapa ahi i hoʻopaʻa ʻia i nā pōʻai lamination, paʻakikī PCB lawelawe a hiki ke hoʻopaʻa ʻia me ke alakaʻi ʻole.Loaʻa i nā pāpaʻi FR-4 maʻamau ka PTFE maʻemaʻe, PTFE piha piha i ka ceramic, a me nā substrates hydrocarbon thermosetting.ʻO kēia nā mea kūikawā o ka substrate FR-4 i kūpono no nā PCB no nā noi koi.
1. Hana maikaʻi i ka uila.
2. Hiki ke kū i ka hoʻomākaukau ʻana a me ka hoʻomākaukau ʻana o ka lua (PTH).
3. Hoʻopili maikaʻi ma o ka hilinaʻi puka.
4. He haʻahaʻa ke kumukūʻai.
5. Stable dissipation factor (Df) i hoʻohālikelike ʻia me nā mea PCB maʻamau.
6. Paipai kemika maikaʻi
7. He kūpono no ka hoʻolālā PCB e koi ana i ka mana koʻikoʻi o ka impedance
8. Hoʻopaʻa haʻalulu, haʻalulu a me ka lapalapa ahi.
Ke noʻonoʻo nei i kāna hana kūʻokoʻa i ka hoʻokele wela, ua koho nui ʻia nā FR-4 High Tg PCBs no nā noi i ka helu helu, mālama a me nā peripheral, nā mea uila uila, nā pūnaewele a me nā ʻōnaehana kamaʻilio, aerospace & Defence, medical, Industrial & Instrumentation, a me nā ʻoihana kaʻa & uila.ʻO ka ʻoihana halihali.
E koho i nā mea pono e hoʻokō i nā hopena i makemake ʻia
Ma waena o nā ʻano mea FR-4 i loaʻa, he mea nui e koho i nā mea kūpono no nā koi noi, no ka mea e hoʻoholo i ka paʻa a me ka hana maikaʻi loa o ka mea hope.Pono e noʻonoʻo ʻia nā mea e like me ka dielectric permittivity, pauna poho, thermal conductivity, transition temperature, coefficient of thermal expansion (CTE), uila, etc., ma mua o ke koho ʻana i nā substrate FR-4 no kāu noi.Inā kānalua ʻoe i ke ʻano o ka mea FR-4 e koho ai, e noʻonoʻo e hana pū me kahi mea hana PCB i ʻike i ka hāʻawi ʻana i nā PCB Tg kiʻekiʻe i nā ʻoihana like ʻole.ʻO RigiFlex Technologies kekahi o nā mea kaulanaNā mea hana PCBma ka mākeke a loaʻa iā lākou ka ʻike lima i ka hāʻawi ʻana i nā PCB Tg kiʻekiʻe ma nā ʻano hoʻonohonoho like ʻole.Noi kiʻekiʻe tg PCB quote i kēia manawa!
