![Ka nui o ke kūʻai aku ʻana o nā mīkini hoʻoluʻu wai ʻoihana ʻo Teyu]()
Kokoke i kēlā me kēia ʻāpana o ka Papa Kaapuni Paʻi (PCB) e pili ana i nā ʻano hana hōʻailona. ʻO ia no ka mea hiki i ka ʻike i paʻi ʻia ma ka PCB ke hoʻokō i ka hana o ka nānā ʻana i ka maikaʻi, ka ʻike ʻakomi a me ka hoʻolaha ʻana i ka brand. Ua paʻi ʻia kēia mau ʻike e nā mīkini paʻi kuʻuna. Akā, hoʻohana nā mīkini paʻi kuʻuna i ka nui o nā mea hoʻopau e hiki ke hoʻohaumia maʻalahi. A mae wale ka ʻike a lākou e paʻi ai i ka hala ʻana o ka manawa, ʻaʻole ia he mea kōkua nui.
Akā no ka mīkini māka laser, ʻaʻole ia he pilikia hou. Loaʻa i ka mīkini māka laser ka hana ʻole-pili, wikiwiki kiʻekiʻe, ʻaʻohe mea hoʻopau a ʻaʻohe haumia. Hiki iā ia ke hoʻomaopopo i nā māka maopopo loa, pololei a lōʻihi hoʻi ma ke ʻano liʻiliʻi loa a hiki i ka 3x3mm. Eia kekahi, ʻoiai ʻaʻohe ona pili pololei, ʻaʻole ia e hōʻino i ka PCB.
Hoʻohana ʻia nā mīkini māka laser PCB maʻamau e ka laser CO2 a me ka laser UV. Ma lalo o nā hoʻonohonoho like, ʻoi aku ka pololei o ka mīkini māka laser UV ma mua o ka mīkini māka laser CO2. ʻO ka nalu o ka laser UV ma kahi o 355nm a hiki i ka hapa nui o nā mea ke omo maikaʻi i ka mālamalama laser UV ma mua o ke kukui infrared. Eia kekahi, ʻo ka laser CO2 he ʻano hana wela e hoʻomaopopo ai i ka hopena māka. No laila, maʻalahi ka carbonization e hana, kahi mea ʻino i nā mea kumu o ka PCB. Ma ke ʻano ʻē, ʻo ka laser UV kahi "hana anu", no ka mea, ʻike ia i ka hopena māka ma ka uhaki ʻana i ka pilina kemika ma o ke kukui laser UV. No laila, ʻaʻole e hōʻino ka laser UV i ka PCB.
E like me kā mākou e ʻike nei, he liʻiliʻi loa ka nui o ka PCB a ʻaʻole maʻalahi ka ʻike māka ma luna. Akā, ua hiki i ka laser UV ke hana ia mea ma ke ʻano kikoʻī. ʻO kēia ka hopena ʻaʻole wale nō ka hiʻohiʻona kū hoʻokahi o ka mīkini māka laser UV akā ʻo ka ʻōnaehana hoʻoluʻu hoʻi e hele mai me ia. He mea nui loa ka ʻōnaehana hoʻoluʻu kikoʻī i ka mālama ʻana i ka mahana o ka laser UV i hiki ai i ka laser UV ke hana pono i kahi manawa lōʻihi. Hoʻohana pinepine ʻia ka ʻāpana chiller compact S&A Teyu CWUL-05 no ka hoʻoluʻu ʻana i ka mīkini māka laser UV ma ka māka PCB. Loaʻa i kēia chiller ka paʻa o ka mahana 0.2℃, ʻo ia hoʻi he liʻiliʻi loa ka loli o ka mahana. A ʻo ka loli liʻiliʻi ʻo ia hoʻi e paʻa ka hopena laser o ka laser UV. No laila, hiki ke hōʻoia ʻia ka hopena māka. Eia kekahi, he liʻiliʻi loa ka nui o ka ʻāpana chiller wai compact CWUL-05, no laila ʻaʻole ia e hoʻopau i ka nui o ka hakahaka a hiki ke komo maʻalahi i loko o ka hoʻolālā mīkini o ka mīkini māka laser PCB.
