No nā mea hana PCB o nā papa HDI, ʻo ka laser drill ke koho maikaʻi loa no ka wili ʻana i nā microvias pololei.He liʻiliʻi ka nui o kēia mau microvias a koi pono i ka ʻeli hohonu ʻana.Hiki ke hoʻokō maʻamau i kēia kikoʻī e nā drills lasers.ʻO ka wili laser ke kaʻina hana e hoʻohana ai i ka ikehu laser koʻikoʻi no ka ʻeli ʻana (vaporizing) i kahi lua.Hoʻokumu ʻo Laser drilling i nā lua kikoʻī ma ka papa PCB e hōʻoia i ka pololei ʻoiai ke hana ʻana me nā liʻiliʻi liʻiliʻi.Hiki i nā lasers ke wili i ka 2.5 a i ka 3-mil vias ma kahi hoʻoikaika aniani pālahalaha lahilahi.I ka hihia o kahi dielectric unreinforced (me ke aniani ʻole), hiki ke wili i 1-mil vias me ka hoʻohana ʻana i nā lasers.No laila, ʻōlelo ʻia ka wili laser no ka wili ʻana i nā microvias.

ʻOiai hiki iā mākou ke wili ma nā puka o ke anawaena 6 mil (0.15 mm) me nā ʻāpana wili mīkini, piʻi nui ke kumukūʻai o nā mea hana i ka wā e paʻi maʻalahi ai nā ʻāpana drill-iki, a pono e hoʻololi pinepine.Ke hoʻohālikelike nei i ka hoʻoheheʻe ʻana i ka mīkini, ua helu ʻia nā mea maikaʻi o ka wili lasers ma lalo nei:

• Kaʻina hana pili ʻole:ʻO ka hoʻoheheʻe laser he kaʻina hana ʻole pili ʻole a no laila ua hoʻopau ʻia ka pōʻino i hoʻokomo ʻia ma ka drill bit a me nā mea e ka wili ʻana i ka vibration.
• Mana pololei:ʻO ka ikaika o ka beam, ka wela wela, a me ka lōʻihi o ka kukuna laser aia ma lalo o ka mana no nā ʻenehana wili laser, no laila e kōkua ai i ka hoʻokumu ʻana i nā ʻano puka like ʻole me ka pololei kiʻekiʻe.ʻO kēia hoʻomanawanui ± 3 mil ma ke ʻano he haʻahaʻa haʻahaʻa ma mua o ka hoʻoheheʻe mechanical me ka PTH tolerance ± 3 mil a me ka NPTH tolerance o ± 4 mil.ʻAe kēia i ka hoʻokumu ʻana o nā makapō, kanu ʻia, a hoʻopaʻa ʻia i ka wā e hana ana i nā papa HDI.

• Lakiō hiʻohiʻona kiʻekiʻe:ʻO kekahi o nā ʻāpana koʻikoʻi o ka lua i wili ʻia ma ka papa kaapuni i paʻi ʻia ʻo ia ka ratio hiʻona.Hōʻike ia i ka hohonu o ka lua i ke anawaena puka o kahi via.No ka mea hiki i nā lasers ke hana i nā lua me nā anawaena liʻiliʻi loa mai ka 3-6 mil (0.075mm-0.15mm), hāʻawi lākou i kahi ratio kiʻekiʻe.He ʻokoʻa ko Microvia i hoʻohālikelike ʻia me kahi maʻamau maʻamau, e hopena i kahi ʻano ʻokoʻa.Loaʻa i kahi microvia maʻamau ka lākiō hiʻohiʻona o 0.75:1.

• Kumukuai:ʻoi aku ka wikiwiki o ka hoʻoheheʻe ʻana i ka laser ma mua o ka wili mīkini, ʻoiai no ka wili ʻana i kau ʻia ma luna o kahi papa multilayer.Eia kekahi, i ka hala ʻana o ka manawa, ʻoi aku ka nui o nā kumukūʻai mai ka hoʻololi pinepine ʻana i nā ʻāpana drill haʻihaʻi a hiki ke lilo i ʻoi aku ke kumukūʻai ʻoi aku ka maikaʻi o ka wili ʻana i ka laser.

• Hana nui:Hiki ke hoʻohana ʻia nā mīkini laser no ka wili ʻana no nā kaʻina hana ʻē aʻe e like me ka welding, ʻoki, etc.

Nā mea hana PCBLoaʻa nā koho lasers like ʻole.Hoʻopuka ʻo PCB ShinTech i nā laser infrared a me ultraviolet no ka wili ʻana i ka wā e hana ana i nā PCB HDI.Pono nā hui like ʻole e like me ka hoʻohana ʻana o nā mea hana PCB i nā mea dielectric e like me resin, reinforced prepreg, a me RCC.

Hiki ke hoʻolālā ʻia ka ikaika o ka beam, ka wela wela, a me ka lōʻihi o ka kukuna laser ma lalo o nā kūlana like ʻole.Hiki i nā kaola ha'aha'a ke wili i nā mea ola akā waiho nā metala me ka poino.No ka ʻoki ʻana i ka metala a me ke aniani, hoʻohana mākou i nā kaola kiʻekiʻe.ʻOiai e koi ana nā kaola haʻahaʻa i nā kaola o 4-14 mil (0.1-0.35 mm) anawaena, pono nā kaola kiʻekiʻe i nā kaola ma kahi o 1 mil (0.02 mm) anawaena.

Ua hōʻiliʻili ʻia ka hui hana o PCB ShinTech ma luna o 15 mau makahiki i ka ʻike i ka hoʻoili ʻana i ka laser a ua hōʻoia i ka moʻolelo o ka kūleʻa i ka hāʻawi ʻana i ka HDI PCB, ʻoi aku hoʻi i ka hana PCB maʻalahi.Hoʻolālā ʻia kā mākou hāʻina e hāʻawi i nā papa kaapuni hilinaʻi a me ka lawelawe ʻoihana me ke kumukūʻai hoʻokūkū e kākoʻo i kāu mau manaʻo ʻoihana i ka mākeke.
