ʻO ka wehewehe ʻana i ka hana plasma

1, Hoʻohana ʻia ka mālama ʻana i nā mea Teflon

Akā ʻo nā ʻenekinia āpau i hana i ka metallization o nā lua material polytetrafluoroethylene i kēia ʻike: ka hoʻohana ʻana i nā mea maʻamau. FR-4 papa kaapuni paʻi nui ʻAʻole kūleʻa ʻo PTFE hole metalization.I waena o lākou, ʻo ka mālama ʻana i ka PTFE ma mua o ka hoʻopaʻa ʻana i ke keleawe keleawe he paʻakikī nui a he hana nui.I ka hana ʻana i ka mālama ʻana i nā mea PTFE ma mua o ka waiho ʻana o ke keleawe keleawe, hiki ke hoʻohana ʻia nā ʻano he nui, akā ma ke ʻano holoʻokoʻa, hiki iā ia ke hōʻoia i ka maikaʻi o nā huahana, kūpono no nā kumu hana nui ʻelua:

a) ʻO ke kaʻina hana kemika: ka sodium metala a me ka radon, ka hopena i nā mea hoʻonā wai ʻole e like me ka tetrahydrofuran a i ʻole glycol dimethyl ether solution, ka hoʻokumu ʻana o kahi paʻakikī nio-sodium, ka hopena mālama sodium, hiki ke hana i nā ʻāpana o Teflon i ka hole are impregnated, to achieve the purpose of wetting the hole wall.He ala maʻamau kēia, hopena maikaʻi, maikaʻi paʻa, hoʻohana nui ʻia.

b) ʻO ke ʻano hana lapaʻau Plasma: maʻalahi kēia kaʻina hana, kūpaʻa a hilinaʻi ka maikaʻi o ka hoʻoponopono ʻana, kūpono no ka hana nui, ka hoʻohana ʻana i ka hana hoʻomaloʻo plasma.ʻO ka hoʻonā lāʻau sodium-crucible i hoʻomākaukau ʻia e ke ʻano lāʻau kemika he paʻakikī ke synthesize, kiʻekiʻe toxicity, pōkole ola ola, pono e hoʻolālā ʻia e like me ke kūlana hana, nā koi palekana kiʻekiʻe.No laila, i kēia manawa, ʻo ka hoʻōla ʻana o ka ʻili o ka PTFE, ʻoi aku ke ʻano o ka mālama ʻana i ka plasma, maʻalahi e hana, a hoʻemi nui i ka mālama ʻana i ka wai ʻino.

2, Hole paia cavitation/puka pā resin wili wehe

No ka FR-4 multi-layer paʻi kaapuni papa hana, kāna CNC drilling after the hole wall resin drilling a me nā mea ʻē aʻe, me ka hoʻohana pinepine ʻana i ka sulfuric acid treatment concentrated, chromic acid treatment, alkaline potassium permanganate treatment, and plasma treatment.Eia nō naʻe, ma ka papa kaapuni paʻi paʻi paʻi a me ka papa kaapuni paʻi paʻi paʻi e wehe i ka hoʻomaʻamaʻa lepo wili, ma muli o nā ʻokoʻa o nā ʻano waiwai, inā hoʻohana ʻia nā ʻano lapaʻau ma luna, ʻaʻole kūpono ka hopena, a me ka hoʻohana ʻana i ka plasma. e wili i ka lepo a me ka wehe concave, hiki iā ʻoe ke kiʻi i kahi ʻoi aku ka maikaʻi o ka paia o ka lua, conducive i ka metallic plating o ka lua, akā loaʻa pū kekahi "ʻekolu-dimensional" concave pili ʻano.

3, Ka wehe ʻana o kahi carbide

ʻO ke ʻano o ka mālama ʻana i ka plasma, ʻaʻole wale no nā ʻano like ʻole o ka hoʻomaʻamaʻa ʻana i ka hoʻomaʻemaʻe ʻana i nā lau, akā no nā mea resin composite a me nā micropores drilling pollution lapaʻau, akā hōʻike pū i kona kiʻekiʻe.Eia kekahi, ma muli o ka hoʻonui nui ʻana o ka noi no nā papa kaapuni paʻi multi-layer me ka nui interconnect density, hana ʻia nā lua makapō me ka hoʻohana ʻana i ka ʻenehana laser. e wehe ʻia ma mua o ke kaʻina hana hole metallization.I kēia manawa, ʻenehana lapaʻau plasma, me ke kānalua ʻole e lawe i ke kuleana o ka wehe ʻana i ke kalapona.

4, Ka hana mua o loko

Ma muli o ka piʻi nui ʻana o ka noi ʻana o nā papa kaapuni paʻi like ʻole, ʻoi aku ka kiʻekiʻe o nā koi ʻenehana hoʻoponopono kūpono.ʻO ka hoʻomaʻamaʻa mua ʻana o ka papa kaapuni paʻi maʻalahi a me ka papa kaapuni paʻi paʻi hiki ke hoʻonui i ka roughness o ka ʻili a me ke degere hoʻāla, hoʻonui i ka ikaika paʻa ma waena o ka papa o loko, a he mea nui hoʻi e hoʻomaikaʻi i ka hua o ka hana.

ʻO nā pōmaikaʻi a me nā pōʻino o ka hana plasma

ʻO ka hana plasma kahi ala kūpono, kūpono a kiʻekiʻe no ka decontamination a me ka etching hope o nā papa kaapuni paʻi.He kūpono loa ka mālama ʻana i ka plasma no nā mea Teflon (PTFE) no ka mea ʻoi aku ka liʻiliʻi o ka hana kemika a hoʻōla ka lāʻau plasma i ka hana.Ma o ka mea hana kiʻekiʻe-frequency (maʻamau 40KHZ), ua hoʻokumuʻia kaʻenehana plasma ma o ka hoʻohanaʻana i ka ikehu o ke kahua uila e hoʻokaʻawale i ke kinoea hana ma lalo o nā kūlana vacuum.Hoʻoulu kēia i nā kinoea hoʻokaʻawale paʻa ʻole e hoʻololi a pahū i ka ʻili.ʻO nā kaʻina hana e like me ka hoʻomaʻemaʻe UV maikaʻi, ka hoʻoulu ʻana, ka ʻai ʻana a me ka crosslinking, a me ka polymerization plasma ka hana o ka mālama ʻana i ka plasma surface.ʻO ke kaʻina hana plasma ma mua o ka hoʻoheheʻe ʻana i ke keleawe, ka nui o ka mālama ʻana i nā lua, ʻo ke kaʻina hana plasma maʻamau: drilling - plasma treatment - copper.Hiki i ka lāʻau lapaʻau ke hoʻoponopono i nā pilikia o ka lua puka, ke koena koena, ka hoʻopaʻa uila maikaʻi ʻole o ka papa keleawe o loko a me ka ʻino ʻole.ʻO ke kikoʻī, hiki i ka lāʻau plasma ke hoʻopau pono i nā koena resin mai ke kaʻina hana drilling, ʻike ʻia hoʻi ʻo drilling contamination.Hoʻopilikia ia i ka hoʻopili ʻana o ka lua keleawe i ka papa keleawe i loko i ka wā metala.I mea e hoʻomaikaʻi ai i ka ikaika paʻa ma waena o ka plating a me ka resin, fiberglass a me ke keleawe, pono e wehe ʻia kēia mau slags maʻemaʻe.No laila, ʻo ka plasma degluing a me ka mālama corrosion e hōʻoia i kahi pilina uila ma hope o ka waiho ʻana o ke keleawe.

ʻO nā mīkini Plasma ka mea maʻamau i nā keʻena kaʻina hana i paʻa i loko o kahi hakahaka a aia ma waena o ʻelua mau papa electrode, i hoʻopili ʻia i kahi mea hana RF e hana i ka nui o nā plasma i loko o ke keʻena hana.I loko o ke keʻena kaʻina hana ma waena o nā papa electrode ʻelua, ʻo ka hoʻonohonoho equidistant he mau pālua o nā pahu kāleka ʻē aʻe e hana i kahi malu no ka multi-gram hiki ke hoʻokipa i nā papa kaapuni hoʻoili plasma.I ke kaʻina hana plasma o ka papa PCB, i ka wā i hoʻokomo ʻia ai ka substrate PCB i loko o ka mīkini plasma no ka hoʻoili ʻana i ka plasma, ua kau ʻia kahi substrate PCB ma waena o kahi slot kāleka pili o ke keʻena hana plasma (ʻo ia hoʻi, kahi ʻāpana i loko o ka hoʻoili plasma. ka papa kaapuni), ua hoʻohana ʻia ka plasma i ka plasma i ka mālama ʻana i ka plasma o ka lua ma ka PCB substrate e hoʻomaikaʻi i ka ʻili o ka lua.

He ʻuʻuku liʻiliʻi ka nui o ka mīkini hana plasma, no laila, ma waena o nā keʻena hoʻoponopono pā electrode ʻelua i hoʻonohonoho ʻia me ʻehā mau lua o nā ʻāpana pā kāleka kūʻē, ʻo ia hoʻi, hiki i ke kūkulu ʻia ʻana o nā poloka ʻehā ke hoʻokipa i ka lumi hoʻokele plasma kaʻapuni kaapuni.Ma keʻano laulā, ʻo 900mm (lōʻihi) x 600mm (kiʻekiʻe) x 10mm (ākea, ʻo ia ka mānoanoa o ka papa) ka nui o kēlā me kēia mānoanoa o ka wahi malu, e like me ke kaʻina hana plasma papa PCB i kēia manawa, i kēlā me kēia manawa ʻO ka papa hana plasma. Loaʻa iā ia ka mana ma kahi o 2 palahalaha (900mm x 600mm x 4), ʻoiai ʻo kēlā me kēia manawa kaʻina hana plasma he 1.5 mau hola, no laila e hāʻawi ana i ka mana hoʻokahi lā ma kahi o 35 mau mika square.Hiki ke ʻike ʻia ʻaʻole kiʻekiʻe ka mana hana plasma o ka papa PCB ma o ka hoʻohana ʻana i ke kaʻina hana plasma o ka papa PCB e kū nei.
