Me he mea lā e ulu mālie ana ka mākeke hoʻoponopono laser i nā makahiki ʻelua i hala. Eia nō naʻe, aia kahi mākeke laser e ulu mau nei i ka wikiwiki wikiwiki - ka mākeke laser pili i ka PCB. No laila pehea ka mākeke PCB o kēia manawa? No ke aha e hiki ai ke lawe mai i ka hoʻomohala nui no ka ʻoihana laser?
ʻO ka ʻoihana PCB a me FPC me ka hoʻomohala wikiwiki a me ka noi mākeke nui
He pōkole ʻo PCB no ka papa kaapuni paʻi a ʻo ia kekahi o nā ʻāpana koʻikoʻi o ka ʻoihana uila. Aia ma kahi kokoke i nā huahana uila a hoʻohana ʻia no ka hoʻopili uila no kēlā me kēia ʻāpana. Aia ka PCB i ka baseboard insulating, ka uwea hoʻohui a me ka pad kahi e ʻākoakoa ai nā mea uila a welt. Hoʻoholo kona maikaʻi i ka hilinaʻi o ka uila, no laila ʻo ia ka ʻoihana kumu a me ka ʻoihana ʻāpana nui loa no ka ʻoihana uila.
He mākeke noi ākea ka PCB, me nā mea uila uila, nā uila uila, kamaʻilio, ka lāʻau lapaʻau, ka pūʻali koa a pēlā aku. No ka manawa, ke ulu wikiwiki nei nā mea hoʻohana uila a me nā uila uila a lilo lākou i mau noi nui no PCB.
Ma waena o ka noi PCB i nā mea kūʻai uila, ʻo FPC ka wikiwiki o ka ulu ʻana a lawe i ka mākeke nui a ʻoi aku ka nui o ka mākeke PCB. Ua ʻike ʻia ʻo FPC he kaapuni paʻi maʻalahi. He papa kaapuni paʻi hilinaʻi loa ia e hoʻohana ana i ka PI a i ʻole polyester film ma ke ʻano he kumu kumu. Hōʻike ia i ke kaumaha māmā, ke kiʻekiʻe kiʻekiʻe o ka puʻunaue uea a me ka maʻalahi maikaʻi, hiki ke hoʻokō pono i ke ʻano naʻauao, lahilahi a māmā i ka uila uila.
Ke alakaʻi nei ka mākeke PCB wikiwiki i kahi mākeke derivative nui. Me ka hoʻomohala ʻana i ka ʻenehana laser, hoʻololi mālie ka hoʻoili ʻana i ka ʻenehana make kuʻuna a lilo i ʻāpana koʻikoʻi i ke kaulahao ʻoihana PCB. No laila, i loko o kēia wahi nui kahi o ka mākeke laser holoʻokoʻa i hoʻomohala lohi, ke ulu wikiwiki nei ka mākeke laser pili PCB.
ʻO ka pōmaikaʻi o ka hana laser ma PCB a me FPC
ʻO ka hana laser ma PCB e pili ana i ka ʻoki ʻana i ka laser, ka hoʻoheheʻe ʻana i ka laser a me ka hōʻailona laser. Ke hoʻohālikelike ʻia me ka ʻenehana ʻoki make maʻamau, ʻo ka ʻoki ʻoki laser ʻaʻole pili a ʻaʻole’t makemake i ka poni pipiʻi a hiki ke hoʻokō i ka pololei kiʻekiʻe me ka ʻole burr ma ka ʻoki ʻoki. Hana kēia i ka ʻenehana laser i ka hopena kūpono no ka ʻoki ʻana i ka PCB a me FPC.
Ma mua, hoʻohana ka ʻoki ʻoki laser i ka PCB i ka mīkini ʻoki laser CO2. Akā ʻo ka mīkini ʻoki laser CO2 he wahi wela nui i hoʻopili ʻia a me ka hana ʻoki haʻahaʻa, ʻaʻole ia he noi ākea. Akā ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana laser, ʻoi aku ka nui o nā kumu laser a hiki ke hoʻohana ʻia i ka ʻoihana PCB.
No ka manawa, ʻo ke kumu laser maʻamau i hoʻohana ʻia ma PCB a me ka ʻoki FPC he nanosecond solid state UV laser nona ka nalu he 355nm. He ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i nā mea a me ka liʻiliʻi o ka wela wela, kahi e hiki ai ke hoʻokō i ka pololei o ka hoʻoili ʻana.
No ka hōʻemi ʻana i ka charring a hoʻokō i ka pono kiʻekiʻe, hoʻomau nā ʻoihana laser i ka hoʻomohala ʻana i ka laser UV o ka mana kiʻekiʻe, ke alapine kiʻekiʻe a me ka laulā pulse haiki. No laila, ua hana ʻia nā lasers UV nanosecond 20W, 25W a me 30W nanosecond no ka hoʻokō maikaʻi ʻana i ka piʻi nui ʻana o ka noi ma ka ʻoihana PCB a me FPC.
Ke piʻi aʻe ka mana o ka laser UV nanosecond, ʻoi aku ka nui o ka wela. No ka mālama ʻana i ka hana kaʻina hana maikaʻi loa, pono ia i kahi chiller laser pololei. S&A Hiki iā Teyu wai hoʻoluʻu chiller CWUP-30 ke hoʻoluʻu nanosecond UV laser a hiki i 30W a me nā hiʻohiʻona.±0.1℃ kūpaʻa. ʻO kēia pololei ka mea e hiki ai i kēia chiller wai lawe lima ke hoʻomalu maikaʻi i ka mahana o ka wai i hiki ai i ka laser UV ke noho mau i kahi pae wela kūpono. No ka ʻike hou aku. e pili ana i kēia chiller, kaomi https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
