I ka wā o ka ʻeli ʻana i ka PCB mechanical, pono e komo mau kahi micro-drill hoʻokahi i nā mea he nui, me ka pepa keleawe, ka resin, ke aniani fiber a me nā mea hoʻopihapiha hana. ʻOiai ke ʻano o ke kaʻina hana e pili ana i ka ʻeli pinepine ʻana, ua hoʻomau ʻia nā ʻaoʻao ʻoki o ka micro-drill i ka ʻaʻahu abrasive mai nā ʻāpana paʻakikī, ka wela frictional a me nā ukana mechanical cyclic.
I ka hoʻomau ʻana o ka hana ʻana o PCB i ka ulu ʻana i ka nui o ke kaapuni, ka nui o nā papa a me nā geometries maikaʻi aʻe, ke emi nei ke anawaena o nā lua i wili ʻia. I kēia manawa, ke hoʻohana nui ʻia nei nā laminates paʻakikī e mīkini, me nā mea Tg kiʻekiʻe a me nā mea hoʻopiha kiʻekiʻe. ʻOi aku ka nui o nā koi i ka wā e hāʻule ai ke anawaena o kahi micro-drill ma lalo o 0.1 mm, ua kau ʻia nā koi koʻikoʻi ma ka ikaika o ka drill-point, ke kūpaʻa ʻana i ka ʻoki ʻana, ka hoʻoneʻe ʻana o nā chip a me ke kūpaʻa holoʻokoʻa o ka wili ʻana.
Ke hoʻohana nui ʻia, ʻoi aku ka hopena ma mua o ka emi ʻana o ke ola o ka mea hana. Hiki nō hoʻi iā ia ke alakaʻi i ka hoʻonui ʻia o ka ʻoʻoleʻa o ka paia o ka lua, nā ʻūpā komo a me ka puka ʻana, ka emi ʻana o ke kūlike o ke anawaena o ka lua a me ka haki ʻana o ka wili.
No laila, ʻo ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻana o nā micro-drills a me ka hōʻemi ʻana i ka friction ma o nā uhi ʻili e lilo nei i mea hana loea koʻikoʻi no ka hoʻomaikaʻi ʻana i ka maikaʻi o ka wili PCB.
1. Hoʻopilikia ka Micro-Drill Wear i nā mea ʻoi aku ma mua o ke ola o ka mea hana
ʻO ka maʻamau, ua hana ʻia nā laminates PCB me ka foil keleawe, ka resin, ke aniani fiber a me nā mea hoʻopihapiha hana like ʻole. I ka wā o ka wili wikiwiki, pono e ʻoki pinepine ka micro-drill i nā mea me nā ʻano mechanical a me nā thermal like ʻole. ʻO nā olonā aniani a me kekahi mau mea hoʻopihapiha paʻakikī e hoʻoulu mau i ka ʻaʻahu abrasive ma ke kiko wili a me nā ʻaoʻao ʻoki, ʻoiai hiki i ka resin ke hoʻopili i ke kiko wili a i ʻole nā ʻohe helical ma lalo o nā hopena hui pū ʻia o ka friction a me ka wela ʻoki, e hoʻopilikia maikaʻi ʻole ana i ka hoʻoneʻe ʻana o nā chip ma hope.
I ka piʻi ʻana o ka nui o nā lua i wili ʻia, e lilo mālie nā ʻaoʻao ʻoki o ka micro-drill i mea ʻōniʻoniʻo. Hoʻonui ʻia ka ikaika axial e pono ai e komo i loko o ka laminate, ʻoiai e hoʻonui hou ʻia ka friction a me ka hana wela. Ma lalo o kēia mau kūlana, e hōʻino mālie ana ka hana ʻoki ma ka foil keleawe, ka resin a me ke aniani fiber, e hopena ana i ka compression, scraping a haehae paha ma mua o ka wehe ʻana i nā mea maʻemaʻe. Hiki i kēia ke hoʻonui i ka roughness o ka paia o ka lua, hana i nā burrs komo a puka i ʻoi aku ka ʻike a hōʻemi i ke kūlike o ke anawaena o ka lua. No nā PCB laina maikaʻi a me nā papa interconnect high-density, a i ʻole HDI, hiki i kēia mau hemahema ke hoʻonui i ka paʻakikī o ka metallization o ka lua a me ka kaohi maikaʻi.
Eia kekahi, ʻo ka liʻiliʻi o ke anawaena micro-drill, ʻoi aku ka palena o ka hiki ke hoʻokipa i nā ʻāpana o kāna mau ʻohe helical. Ke hōʻiliʻili nā ʻāpana a pili paha ka resin i kahi wili, nā ʻaoʻao ʻoki a i ʻole nā ʻohe ʻāpana, hiki ke loli nui ke kūʻē ʻana o ka wili. Ke hui pū ʻia me ka ʻaʻahu micro-drill, ka holo ʻana o ka spindle a i ʻole nā palena wili kūpono ʻole, hiki ke hoʻonui ʻia nā ukana kūlou a me nā torsional e hana ana ma ka micro-drill, no laila e hoʻonui ai i nā pilikia o ka deflection drill a me ka haki ʻana.
2. Pehea e hoʻomaikaʻi ai nā uhi Micro-Drill i ka ʻeli ʻana o ka PCB?
Hiki ke waiho ʻia nā uhi paʻakikī e like me ta-C, AlTiN, AlCrN a me CrN ma luna o nā micro-drills PCB. Ma waena o kēia mau mea, hoʻohui ka carbon amorphous tetrahedral, a i ʻole ta-C, i ka paʻakikī kiʻekiʻe me kahi coefficient haʻahaʻa o ka friction, e kōkua ana i ka hōʻemi ʻana i ka ʻoki ʻana a me ke kū'ē ʻana i ka wili ʻana me ka pale ʻana i ke kiko wili a me nā ʻaoʻao ʻoki. I nā noi hana, hoʻomaikaʻi nā uhi micro-drill i ka hana wili ma ka hoʻopaneʻe ʻana i ka ʻoki ʻana, ka hōʻemi ʻana i ka friction a me ke kū'ē ʻana i ka chip-evacuation, a me ka hoʻopaʻa ʻana i ka maikaʻi o ka lua.
Hoʻemi nā uhi paʻakikī kiʻekiʻe i ka pilina pololei ma waena o nā olonā aniani, nā mea hoʻopihapiha paʻakikī a me ka substrate cemented-carbide. Kōkua kēia i ka lohi o ka ʻaʻahu ʻana ma ke kiko wili, nā kihi ʻoki mua a me nā kaʻe, e ʻae ana i ka micro-drill e mālama i kahi kūlana ʻoki paʻa ma luna o kahi helu nui o nā pōʻaiapuni wili.
Kōkua nā uhi haʻahaʻa haʻalulu i ka hōʻemi ʻana i ka haʻalulu ma waena o ka micro-drill, PCB laminate a me nā ʻāpana i hana ʻia. Hiki iā lākou ke hōʻemi i ke ʻano o nā ʻāpana a me ka resin e hoʻopili i ka wahi wili a me nā ʻohe helical, e hana ana i nā kūlana ʻili maikaʻi no ka hoʻoneʻe ʻana o nā ʻāpana.
Ke kāohi pono ʻia ka nui o ke komo ʻana o nā ʻaoʻao ʻoki, hiki ke hoʻemi ʻia nā ʻano like ʻole o ke kūlana ʻoki i nā pae like ʻole o ka mīkini. Kōkua kēia i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka paia lua a me ke kūlike o ke anawaena lua me ka kaupalena ʻana i ka hoʻokumu ʻia ʻana o nā burrs komo a me waho.
Eia nō naʻe, ʻaʻole hiki i nā uhi ke hoʻopau loa i ka haki ʻana o ka wili. Pili pū ka hemahema o ka wili i ke anawaena micro-drill, ke ʻano laminate, ke kiʻekiʻe o ka stack, ke kūlana spindle a me nā palena wili. Ma ka hoʻolohi ʻana i ka ʻaʻahu, ka hōʻemi ʻana i ka friction a me ka hoʻomaikaʻi ʻana i ka hoʻoneʻe ʻana o nā chip, hiki i kahi uhi i hana pono ʻia ke hōʻemi i nā ukana ʻoki maʻamau ʻole a no laila e hoʻemi i ka pilikia o ka haki ʻana o ka wili.
3. Pono nā Micro-Drills liʻiliʻi i nā kaʻina hana uhi pololei aʻe
Ke hoʻohālikelike ʻia me nā mea hana ʻoki maʻamau, ʻoi aku ka liʻiliʻi o nā ana o nā micro-drills PCB a ʻoi aku ka maʻalahi o ka drill-point a me nā geometries ʻoi aku ka maikaʻi. No laila, ʻaʻole hiki i nā uhi micro-drill ke kālele wale i ka hoʻokō ʻana i ka paʻakikī kiʻekiʻe. Pono e hoʻomalu pono ʻia ka mānoanoa o ke kiʻiʻoniʻoni, ka maikaʻi o ka ʻili a me ka hoʻopili ʻana o ka coating-substrate.
Inā lahilahi loa ka uhi, ʻaʻole paha lawa kona pale ʻana mai ka ʻaʻahu abrasive. Inā mānoanoa loa, hiki ke hoʻololi i ke ʻano microscopic o ka ʻoi ʻoki a hana i ka ʻōpuni ʻana o ka ʻaoʻao a i ʻole ka blunting. ʻO ka liʻiliʻi o ke anawaena micro-drill, ʻoi aku ka maʻalahi o kāna hana ʻoki i ka mānoanoa o ka uhi.
Hiki i ka waiho ʻana o ke arc cathodic maʻamau ke hoʻoulu i nā macroparticles. Inā waiho ʻia kēia mau macroparticles ma kahi kokoke i ke kiko wili, ka ʻoki ʻana a i ʻole ka palena, hiki iā lākou ke hoʻonui i ka ʻoʻoleʻa o ka ʻili uhi a hoʻopilikia i ka ʻoi o ka ʻoki ʻana. No nā micro-drills ultra-fine me nā diameters ma lalo o 0.1 mm, hiki i nā ʻāpana o ka nui like ke loaʻa ka hopena pili nui aʻe ma ke ʻano ʻoki.
Loaʻa i nā micro-drills nā hiʻohiʻona paʻakikī ʻekolu-dimensional, me ke kiko wili, nā kihi ʻokiʻoki, nā kaʻe a me nā ʻohe chip helical. No laila, i ka wā o ka uhi ʻana o ka batch, ka hoʻolālā fixture, ka nui o ka ukana a me ka neʻe ʻana o ka substrate e hoʻokō i ka uhi uhi kūpono ma luna o nā wahi hana like ʻole me ka mālama ʻana i ke kūlike ma waena o nā micro-drills pākahi.
