Mea Hana PCB hoʻokūkū

Pcb multi-layer circuit board manufacturers a profession technical research and development team, haku i ka oihana kaʻina hana 'enehana, a he pono hana pono, ho'āʻo hale a me ke kino a me ka kemikala laboratories me nā 'ano hana like 'ole. ʻO ka FR-4 a mākou e kamaʻilio nei ma aneʻi ʻo ia ka ʻano pepa i hoʻohana pinepine ʻia i ka hana ʻana i nā papa kaapuni pcb multilayer.
ʻO ka laminate keleawe i hoʻohana nui ʻia a prepreg i ka honua ʻo NEMA i kapa ʻia ʻo FR4.
e pili ana i ka 14% o ka huina hoopuka he hookahi-aoao a elua-aoao FR-4 papa, a me ke koena ma kahi o 40% o ka multi-layer papa mea lahilahi FR -4 laminates. ʻO ka hopena o ka mōʻaukala o FR-4's ka mana o ka mākeke ma muli o ka ʻoi aku o ka nui o nā laminates e pili ana i ka pepa i nā waiwai wela, hoʻomaikaʻi i ka wai a me ke kūpaʻa kemika, ka ikaika flexural kiʻekiʻe a me ka ikaika peel maikaʻi. . ʻO FR4 ka laminate mua i hiki ke hoʻohana ʻia no nā ʻaoʻao ʻelua ʻaoʻao puna-wai-puka ma muli o kona kū'ē ʻana i ka makū a me ka exfoliation kemika. Eia kekahi, ʻaʻole hiki ke lanakila ka waiwai o FR-4 no ke kālā. I nā makahiki, ua manaʻo ka ʻoihana e hāʻawi ʻo FR-4 i nā mea laminate hou i kūkulu ʻia i kūpono no ka nui o ka hui kiʻekiʻe. Eia nō naʻe, ma muli o ke kaohi ʻana o ke kumukūʻai, ke ʻimi nei nā mea hoʻolālā papa kaapuni i nā ala e hoʻohana ai i ka FR-4 i nā hui kiʻekiʻe.
ʻO ka mea hoʻoikaika i hoʻohana ʻia no nā laminates FR4 he aniani uila Wib (E-aniani). Ma muli o kāna mau waiwai mechanical maikaʻi loa, ʻoluʻolu nā waiwai insulation uila, pale wela, pale ʻana i ka makū a me ka pale ʻana i ka waika, ua lilo ka lole lole aniani E-type i mea hoʻoikaika uila maikaʻi loa. ʻO nā lole a pau i hoʻohana ʻia ma FR4 he ʻano maʻemaʻe ka ʻili e like me ke ʻano o ka ulana ʻana i ka hīnaʻi, a ua uhi ʻia ka ʻili me kahi papa pena e hoʻoikaika ai i ka hui ma waena o nā fiber aniani a me nā resins maoli. I ka wā o ke kaʻina ulana hōʻemi, hoʻoholo ʻia ka mānoanoa a me ka helu o nā fiber aniani. Hoʻoholo ʻia ke kaumaha kumu a me ka mānoanoa o ka lole i hoʻopau ʻia, ʻo ka mānoanoa o ka lole aniani i hoʻohana ʻia no ka papa i paʻi ʻia ka hapa nui mai 6 a 172m, a ʻo ka prepreg i haku ʻia i ka lole aniani aniani e hoʻoholo ai i ka mānoanoa o ka laminate. ʻO ka maʻamau, ʻo ka mānoanoa o ka FR4 laminate he bam ~ 1L57mm (e piʻi ana i nā manawa o 25pm), a ʻo ka mānoanoa kikoʻī e pili ana i ke ʻano o ka lole fiber aniani a me ka ʻike resin maoli o ka pepa semi-chemical i hoʻohana ʻia. ʻO ka hana o kahi laminate ka mea i hoʻoholo mua ʻia e ka hale, no ka mea, pono ka mea kūʻai aku e hana pono i nā koi, a no ka mānoanoa i hāʻawi ʻia, nui nā hale e hiki ke hoʻokō i nā tolerances i hāʻawi ʻia. ʻO nā ʻano like ʻole o ka ʻike resin maoli (i kekahi manawa i kapa ʻia ʻo ka ratio o ka lāʻau i ka lole fiberglass) e pili i nā waiwai o ka laminate.
ʻO ka ʻōnaehana holoʻokoʻa o ka resin kūlohelohe epoxy i haku ʻia me nā pūhui epoxy ikaika, a loaʻa ka resin bifunctional epoxy kūlohelohe (kēlā me kēia o kāna mau mea) ma o ka synthesis o kahi hui epoxy hoʻokahi a me ka tetrabromofluorescein A (TBPA). ʻElua mau pūhui oxygen epoxy reactive ma ke kaulahao polymer), e like me ka hōʻike ʻana ma ke Kiʻi 4.6. ʻO ka lōʻihi o ke kaulahao ma waena o nā hui e hoʻoholo i ka rigidity o ka laminate a me nā mea wela o ka laminate. I ka wā o ke kaʻina hana ho'ōla, hoʻopili nā hui oxygen epoxy me ka mea hoʻōla e hoʻomaka i kahi matrix polymer ʻekolu. Ma ke ʻano he ʻāpana o ke kaulahao polymer, ua hoʻohui ʻia ʻo Wakamura bromine i ka TBBPA, kahi e loaʻa ai iā TBPA nā waiwai pale ahi. Wahi a Underwriters Laboratories
(Underwriters Laboratory) UL94 ho'āʻo, i mea e hana i ka pau laminate me V0 pae o ka lapalapa ahi retardancy, pono e hoʻohui bromine ma waena o 16% a me 21% ma ke kaumaha.
ʻO nā huahana pcb kaapuni papa ma pcb multilayer kaapuni papa hana uhi 2-28 papa papa, HDI papa, kiʻekiʻe TG mānoanoa papa keleawe, palupalu a paakiki papa hoʻopaʻa papa, kiʻekiʻe alapinepine papa, hui 'ia laminates media, makapo kanuia ma o ka papa, metala substrates a me ka ole. Pāpā halogen. ʻO ka pōmaikaʻi o Shenzhen kaʻa kaʻa kaʻa kaʻa i loko o nā ʻano wrenches waena a hiki i ke kiʻekiʻe, a ʻoi aku ka maikaʻi o ke kumukūʻai, a aia nō ia i kahi kūlana alakaʻi i ka ʻoihana pcb.
