01

ʻO ke kukui laser lahilahi loa ma hope o ka nānā ʻana i ka laser e like me kahi mea hana, hiki ke hoʻoneʻe i ka ʻili o ka mea i kēlā me kēia kiko. ʻO kona kūlana kiʻekiʻe, ʻo ke kaʻina mākaʻikaʻi ʻaʻole i hoʻopili ʻia, ʻaʻole ia e hoʻopuka i ka mechanical extrusion a i ʻole mechanical stress, no laila ʻaʻole ia e hōʻino i ka ʻatikala i hana ʻia; Ma muli o ka liʻiliʻi liʻiliʻi o ka laser ma hope o ka nānā ʻana, ka wahi liʻiliʻi i hoʻopili ʻia i ka wela, a me ka hoʻoponopono maikaʻi ʻana, hiki ke hoʻopau ʻia kekahi mau hana i hiki ʻole ke hoʻokō ʻia e nā ʻano hana maʻamau.

02

ʻO ka "mea hana" i hoʻohana ʻia i ka hoʻoili ʻana i ka laser ʻo ia ka wahi kukui i kuhikuhi ʻia. ʻAʻole pono nā lako a me nā mea hou aku. ʻOiai hiki ke hana maʻamau ka laser, hiki ke hana mau ʻia no ka manawa lōʻihi. He wikiwiki ka wikiwiki o ka hana laser a he haʻahaʻa ke kumukūʻai. Hoʻomalu ʻia ka hoʻoili ʻana i ka laser e ke kamepiula, a ʻaʻohe pono o ke kanaka i ka wā hana.

03

ʻO ke ʻano o ka ʻike e hiki ai i ka laser ke hōʻailona e pili wale i ka ʻike i hoʻolālā ʻia i loko o ke kamepiula. ʻOiai hiki ke ʻike ʻia e ka ʻōnaehana kaha kiʻi i hoʻolālā ʻia i loko o ke kamepiula, hiki i ka mīkini māka ke hoʻihoʻi pololei i ka ʻike hoʻolālā ma kahi mea lawe kūpono. No laila, hoʻoholo maoli ka hana o ka polokalamu i ka hana o ka ʻōnaehana i ka nui.

I ka hoʻohana ʻana i ka laser o ke kahua SMT, ua hana nui ʻia ka traceability hōʻailona laser ma ka PCB, a ʻo ka luku ʻana o ka laser o nā lōʻihi hawewe like ʻole i ka PCB tin masking layer ʻaʻole kūlike.

I kēia manawa, ʻo nā lasers i hoʻohana ʻia i ka coding laser me nā laser fiber, nā laser ultraviolet, nā laser ʻōmaʻomaʻo a me nā lasers CO2. ʻO nā lasers maʻamau i hoʻohana ʻia i ka ʻoihana he UV lasers a me CO2 lasers. ʻOi aku ka liʻiliʻi o ka hoʻohana ʻana i nā laser fiber a me nā laser ʻōmaʻomaʻo.

 

laser fiber-optic

ʻO ka fiber pulse laser e pili ana i kahi ʻano laser i hana ʻia e ka hoʻohana ʻana i ka fiber glass doped me nā mea ʻano honua laha loa (e like me ytterbium) ma ke ʻano he mea waiwai. Loaʻa iā ia kahi pae ikehu luminous waiwai loa. ʻO 1064nm ka lōʻihi o ka nalu o ka pulupulu fiber laser (e like me ka YAG, akā ʻo ka ʻokoʻa ka mea hana a YAG he neodymium) (QCW, ʻo ka hoʻomau ʻana o ka fiber laser i ka nalu maʻamau o 1060-1080nm, ʻoiai ʻo QCW he laser pulsed, akā ʻo kona pulse. He ʻokoʻa loa ka mīkini hana, a ʻokoʻa hoʻi ka lōʻihi nalu), he laser kokoke-infrared. Hiki ke hoʻohana ʻia e hōʻailona i nā mea metala a me nā mea metala ʻole ma muli o ke kiʻekiʻe o ka absorption rate.

Hoʻokō ʻia ke kaʻina hana ma ka hoʻohana ʻana i ka hopena wela o ka laser ma ka mea, a i ʻole ma ka hoʻomehana ʻana a me ka hoʻoheheʻe ʻana i ka mea ʻili e hōʻike i nā ʻāpana hohonu o nā kala like ʻole, a i ʻole ma ka hoʻomehana ʻana i nā loli kino microscopic ma luna o ka ʻili o ka mea (e like me kekahi nanometers, ʻumi nanometer) E hoʻopuka nā puka micro-nui i kahi hopena kino ʻeleʻele, a hiki ke ʻike liʻiliʻi ke kukui, e ʻike ʻia ka mea ʻeleʻele ʻeleʻele) a e loli nui kāna hana noʻonoʻo, a i ʻole ma o kekahi mau hopena kemika e hana ʻia ke hoʻomehana ʻia e ka ikehu māmā. , e hōʻike i ka ʻike e pono ai e like me nā kiʻi, nā huapalapala, a me nā code QR.

 

UV laser

ʻO ka laser Ultraviolet kahi laser lōʻihi pōkole. ʻO ka maʻamau, hoʻohana ʻia ka ʻenehana pālua pinepine e hoʻohuli i ke kukui infrared (1064nm) i hoʻokuʻu ʻia e ka laser solid-state i 355nm (triple frequency) a me 266nm (quadruple frequency) ultraviolet light. He nui loa kona ikehu photon, hiki ke hoohalike i ka ikehu o kekahi mau paa kemika (ionic bonds, covalent bonds, metal bonds) o na mea a pau o ke ano maoli, a uhai pono i na paa kemika, no ka mea, e komo ka mea i ka photochemical reactions me ka maopopo ole. nā hopena wela (nucleus, Hiki i kekahi mau pae ikehu o nā electrons i loko ke komo i nā kiʻi ultraviolet, a laila e hoʻololi i ka ikehu ma o ka haʻalulu lattice, ka hopena i ka hopena wela, akā ʻaʻole maopopo), nona ka "hana anu". No ka mea ʻaʻohe hopena wela, ʻaʻole hiki ke hoʻohana ʻia ka laser UV no ka wili, hoʻohana maʻamau no ka hōʻailona ʻana a me ka ʻoki pololei.

Hoʻomaopopo ʻia ke kaʻina hana hōʻailona UV ma ka hoʻohana ʻana i ka hopena photochemical ma waena o ke kukui UV a me ka mea e hoʻololi ai ke kala. ʻO ka hoʻohana ʻana i nā ʻāpana kūpono hiki ke pale i ka hopena wehe ʻike ʻia ma ka ʻili o ka mea, a no laila hiki ke kaha i nā kiʻi a me nā kiʻi me ka ʻole o ka hoʻopā ʻana.

ʻOiai hiki i nā laser UV ke hōʻailona i nā metala a me nā metala ʻole, ma muli o nā kumu kumu kūʻai, hoʻohana mau ʻia nā laser fiber e hōʻailona i nā mea metala, ʻoiai hoʻohana ʻia nā lasers UV e hōʻailona i nā huahana e koi ana i ka maikaʻi o ka ʻili kiʻekiʻe a paʻakikī ke hoʻokō me CO2, e hana ana i kahi kiʻekiʻe-haʻahaʻa hoʻokūkū me CO2.

 

Laser ʻōmaʻomaʻo

ʻO ka laser ʻōmaʻomaʻo he laser lōʻihi pōkole. ʻO ka maʻamau, hoʻohana ʻia ka ʻenehana pālua pinepine e hoʻohuli i ke kukui infrared (1064nm) i hoʻokuʻu ʻia e ka laser paʻa i ke kukui ʻōmaʻomaʻo ma 532nm (ʻelua pinepine). ʻO ka laser ʻōmaʻomaʻo he kukui ʻike ʻia a ʻo ka laser ultraviolet he kukui ʻike ʻole ʻia. . ʻO ka laser Green he ikehu photon nui, a ʻo kona mau hiʻohiʻona kaʻina anu e like loa me ka kukui ultraviolet, a hiki ke hana i nā ʻano koho like ʻole me ka laser ultraviolet.

ʻO ke kaʻina hana hōʻailona kukui ʻōmaʻomaʻo e like me ka laser ultraviolet, e hoʻohana ana i ka hopena photochemical ma waena o ke kukui ʻōmaʻomaʻo a me ka mea e hoʻololi ai ke kala. Hiki i ka hoʻohana ʻana i nā ʻāpana kūpono ke pale i ka hopena wehe ʻike ʻia ma ka ʻili waiwai, no laila hiki iā ia ke hōʻailona i ke kumu me ka ʻole o ka paʻi ʻana. E like me nā huaʻōlelo, aia ma ka ʻaoʻao o ka PCB, he nui nā kala. He maikaʻi ka pane ʻana o ka laser ʻōmaʻomaʻo iā ia, a ʻo nā kiʻi i kaha ʻia he akaka a maʻalahi.

 

CO2 laser

ʻO CO2 kahi laser kinoea hoʻohana maʻamau me ka nui o ka ikehu kukui. ʻO ka lōʻihi hawewe laser maʻamau he 9.3 a me 10.6um. ʻO ia kahi laser infrared mamao me ka mana hoʻopuka hoʻomau a hiki i nā ʻumi kilowatts. Hoʻohana pinepine ʻia kahi laser CO2 haʻahaʻa haʻahaʻa e hoʻopau i ke kaʻina hana Marking kiʻekiʻe no nā molekala a me nā mea ʻole metala. ʻO ka maʻamau, ʻaʻole i hoʻohana pinepine ʻia nā laser CO2 e hōʻailona i nā metala, no ka mea he haʻahaʻa loa ka helu absorption o nā metala (hiki ke hoʻohana ʻia ka mana kiʻekiʻe CO2 e ʻoki a weld i nā metala. a me nā mea ʻē aʻe, ua hoʻohana mālie ʻia e nā fiber lasers replace).

Hoʻomaopopo ʻia ke kaʻina hana hōʻailona CO2 ma o ka hoʻohana ʻana i ka hopena wela o ka laser ma luna o ka mea, a i ʻole ma ka hoʻomehana ʻana a me ka hoʻoheheʻe ʻana i ka mea ʻili e hōʻike i nā papa hohonu o nā mea kala like ʻole, a i ʻole ma ka hoʻomehana ʻana o ka ikehu i nā loli kino microscopic ma luna o ka ʻili o ka mea. E hoʻomanaʻo i nā loli koʻikoʻi, a i ʻole kekahi mau hopena kemika i hana ʻia ke hoʻomehana ʻia e ka ikehu māmā, a hōʻike ʻia nā kiʻi, nā huapalapala, nā code ʻelua-dimensional a me nā ʻike ʻē aʻe.

Hoʻohana pinepine ʻia nā laser CO2 i nā mea uila, nā mea kani, nā lole, ka ʻili, nā ʻeke, nā kāmaʻa, nā pihi, nā aniani, nā lāʻau lapaʻau, nā meaʻai, nā mea inu, nā mea hoʻonaninani, nā mea hoʻopili, nā mea uila a me nā ʻano ʻē aʻe e hoʻohana ana i nā mea polymer.
