I ke kaʻina hana PCB, ʻo ke kaʻina hana maʻamau he mea nui loa. ʻAʻole pili wale ia i ke ʻano o ka PCB, akā pili pū kekahi i ka hana, hilinaʻi a me ka lōʻihi o ka PCB. Hiki i ke kaʻina hana lapaʻau ili ke hāʻawi i kahi papa pale e pale i ka corrosion keleawe, hoʻonui i ka hana soldering, a hāʻawi i nā waiwai insulation uila maikaʻi. ʻO kēia ka nānā ʻana o nā kaʻina hana lapaʻau maʻamau i ka hana PCB.
一.HASL (Hot Air Smoothing)
ʻO ka hoʻolālā ea wela (HASL) he ʻenehana lapaʻau PCB maʻamau e hana ana ma ke kaomi ʻana i ka PCB i loko o kahi pahu i hoʻoheheʻe ʻia a hoʻohana i ka ea wela e "hoʻolālā" i ka ʻili e hana i kahi uhi metala like ʻole. ʻO ke kaʻina hana HASL he haʻahaʻa haʻahaʻa a kūpono hoʻi no nā ʻano hana PCB like ʻole, akā hiki ke loaʻa nā pilikia me nā pads ʻole a me ka mānoanoa o ka uhi metala.
二.ENIG (gula nickel kemikala)
ʻO ke gula nickel electroless (ENIG) kahi hana e waiho ai i kahi papa nickel a me ke gula ma ka ʻili o kahi PCB. ʻO ka mua, hoʻomaʻemaʻe ʻia ka ʻili keleawe a hoʻāla ʻia, a laila waiho ʻia kahi ʻāpana lahilahi o ka nickel ma o ka hopena hoʻololi kemika, a ma hope ua uhi ʻia kahi papa gula ma luna o ka papa nickel. Hāʻawi ke kaʻina hana ENIG i ke kūpaʻa hoʻopili maikaʻi a me ke kūpaʻa a kūpono no nā noi me nā koi hilinaʻi kiʻekiʻe, akā he kiʻekiʻe ke kumukūʻai.
三、gula kemika
Waiho ʻo Chemical Gold i kahi ʻāpana gula lahilahi ma ka ʻili PCB. Hoʻohana pinepine ʻia kēia kaʻina hana i nā noi ʻaʻole pono e kūʻai aku, e like me ke alapine o ka lekiō (RF) a me ka microwave circuits, no ka mea, hāʻawi ke gula i ka conductivity maikaʻi loa a me ke kūpaʻa corrosion. ʻOi aku ka liʻiliʻi o ke gula kemika ma mua o ENIG, akā ʻaʻole ia e like me ka ENIG.
四、OSP (kiʻiʻoniʻoni pale kino)
ʻO ke kiʻiʻoniʻoni palekana Organic (OSP) kahi hana e hana ai i kahi kiʻiʻoniʻoni organik lahilahi ma luna o ka ʻili keleawe e pale ai i ke keleawe mai ka oxidizing. He hana maʻalahi ka OSP a me ke kumu kūʻai haʻahaʻa, akā ʻo ka pale i hāʻawi ʻia he palupalu a kūpono no ka mālama pōkole a me ka hoʻohana ʻana i nā PCB.
五、Ke gula paʻakikī
ʻO ke gula paʻakikī kahi hana e waiho ai i kahi ʻāpana gula ʻoi aku ka mānoanoa ma ka PCB ma o ka electroplating. ʻOi aku ka pale ʻana o ke gula paʻa ma mua o ke gula kemika a kūpono i nā mea hoʻohui e koi pinepine ai i ka hoʻopili ʻana a me ka wehe ʻana a i ʻole nā PCB i hoʻohana ʻia i nā wahi paʻakikī. ʻOi aku ke kumu kūʻai o ke gula paʻa ma mua o ke gula kemika akā hāʻawi ʻoi aku ka maikaʻi o ka pale no ka wā lōʻihi.
六、Kālā Kaiapuni
ʻO ka Immersion Silver kahi hana no ka waiho ʻana i kahi ʻāpana kālā ma ka ʻili o PCB. Loaʻa i ke kālā ka conductivity a me ka reflectivity maikaʻi, kūpono ia no nā noi ʻike ʻia a infrared. ʻO ke kumu kūʻai o ke kaʻina kālā immersion he haʻahaʻa, akā ua maʻalahi ka vulcanized o ka papa kālā a koi aku i nā mea pale hou.
七、Pina Immersion
ʻO ka Immersion Tin kahi hana no ka waiho ʻana i kahi papa tin ma ka ʻili o ka PCB. Hāʻawi ka papa tin i nā waiwai kūʻai maikaʻi a me kekahi pale ʻana i ka corrosion. He ʻoi aku ka liʻiliʻi o ke kaʻina hana immersion, akā maʻalahi ka hoʻoheheʻe ʻia o ka papa tin a makemake pinepine i kahi papa pale hou.
八、Lead-Free HASL
ʻO ka HASL Lead-Free he kaʻina HASL e pili ana i ka RoHS e hoʻohana ana i ke kēpau / kala / keleawe ʻole ke alakaʻi e pani ai i ke kinikini kuʻuna. Hāʻawi ke kaʻina hana HASL alakaʻi ʻole i ka hana like me ka HASL kuʻuna akā hoʻokō i nā koi kaiapuni.
Aia nā ʻano kaʻina hana lapaʻau i ka hana PCB, a loaʻa i kēlā me kēia kaʻina kona pono kūʻokoʻa a me nā hiʻohiʻona noi. Ke koho ʻana i ke kaʻina hana lapaʻau kūpono e pono ai e noʻonoʻo i ke kaiapuni noi, nā koi o ka hana, nā kumukūʻai kumukūʻai a me nā kūlana palekana o ka PCB. Me ka hoʻomohala ʻana o ka ʻenehana uila, ke hoʻomau nei nā kaʻina hana lapaʻau hou, hāʻawi i nā mea hana PCB me nā koho hou aʻe e hoʻokō i nā koi o ka mākeke.
