1. PCB ma o ka hole plating
Nui nā ala e kūkulu ai i kahi papa o ka plating e hoʻokō i nā koi ma ka paia o ka lua o ka substrate. Kapa ʻia kēia ʻo ka hole wall activation i nā noi ʻoihana. Hoʻohana nā mea hana papa PCB i ka nui o nā pahu mālama waena i ke kaʻina hana. ʻO kēlā me kēia pahu mālama ʻO ka pahu i kona mana ponoʻī a mālama pono. ʻO ka electroplating through-hole ka mea e pono ai ka hana ʻana o ke kaʻina hana wili. Ke hoʻoheheʻe ʻia ka drill bit ma loko o ka pahu keleawe a me ka substrate ma lalo, hoʻoheheʻe ka wela i hana ʻia i ka resin synthetic insulating i hoʻokumu i ke kumu o ka hapa nui o nā substrates, ka resin hoʻoheheʻe ʻia a me nā ʻāpana wili ʻē aʻe Ua waiho ʻia a puni ka puka paia i loko o ka pepa keleawe, he mea ino maoli no ia i ka ili o ka papa.
E waiho pū ka resin hoʻoheheʻe i kahi papa o ke koʻi wela ma ka paia o ka lua o ka substrate, e hōʻike ana i ka hoʻopili maikaʻi ʻole i ka hapa nui o nā mea hoʻoulu, e koi ana i ka hoʻomohala ʻana i kahi papa o nā ʻenehana e like me ka wehe ʻana i nā stain a me ka etchback chemistry. ʻO kahi ʻano i kūpono i ka prototype o nā papa kaapuni i paʻi ʻia, ʻo ia ka hoʻohana ʻana i kahi ʻīnika haʻahaʻa haʻahaʻa i hoʻolālā kūikawā ʻia e hana i kahi uhi paʻa loa a me ka conductive nui ma ka paia o loko o kēlā me kēia puka. Ma kēia ala, ʻaʻohe pono e hoʻohana i nā kaʻina hana kemika he nui, hoʻokahi wale nō kaʻina noi, a ukali ʻia e ka thermal curing, hiki ke hana i kahi uhi hoʻomau i loko o nā paia puka āpau, hiki ke hoʻopili pololei ʻia me ka ʻole o ka mālama ʻana. ʻO kēia ʻīnika kahi mea resin i hoʻopaʻa ʻia a hiki ke hoʻopaʻa maʻalahi i ka nui o nā paia puka i hoʻomaʻamaʻa ʻia, pēlā e hoʻopau ai i ke ala o ka etch back.
2. Reel linkage type selective plating
ʻO nā pine a me nā pine o nā mea uila, e like me nā mea hoʻohui, nā kaʻa i hoʻohui ʻia, nā transistors, a me nā papa FPCB maʻalahi, ua hoʻopaʻa ʻia no ka loaʻa ʻana o ke kūpaʻa hoʻopili maikaʻi a me ka pale ʻana i ka corrosion. Hiki i kēia ʻano hana electroplating ke manual a i ʻole, a he mea kūʻai nui ke koho ʻana i kēlā me kēia pine i kēlā me kēia no ka plating, no laila pono e hoʻohana ʻia ka wiliwili nui. ʻO ka maʻamau, ʻo nā ʻaoʻao ʻelua o ka pahu metala i ʻōwili ʻia i ka mānoanoa i koi ʻia, hoʻomaʻemaʻe ʻia e nā ʻano kemika a i ʻole nā ​​hana mechanical, a laila koho ʻia e like me nickel, gula, kālā, rhodium, pihi a tin-nickel alloy, copper-nickel alloy , Nickel -lead alloy, etc. no ka plating mau. Ma ke ʻano electroplating o ka koho koho, ʻo ka mea mua, ua uhi ʻia kahi ʻāpana o ke kiʻi kūʻē ma ka ʻaoʻao o ka pā keleawe keleawe ʻaʻole pono e hoʻopili ʻia, a ʻo ka ʻāpana keleawe wale nō i koho ʻia.
3. Hoʻopili lima lima
Pono e uhi ʻia ka metala kakaʻikahi ma ka ʻaoʻao o ka papa hoʻohui, ka ʻaoʻao o ka papa e hoʻopili ʻia a i ʻole ka manamana gula e hāʻawi i ke kūpaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa ʻoi aʻe. Kapa ʻia kēia ʻano hana ʻana i ka lālani manamana lima a i ʻole ka hoʻopalapala ʻāpana ʻāpana. Hoʻopili pinepine ʻia ke gula ma nā mea hoʻopili kūwaho o ka mea hoʻohui lihi me ka nickel plating ma ka papa o loko. Hoʻohana ka manamana gula a i ʻole ka ʻaoʻao o ka ʻaoʻao o ka papa i ka ʻenehana hoʻopaʻa lima a i ʻole. I kēia manawa, ua uhi ʻia ka pā gula ma ka plug contact a i ʻole ka manamana gula me ke kupuna wahine a me ke alakaʻi, Plated pihi ma kahi.
Penei ke kaʻina hana:

1. Wehe i ka uhi no ka wehe ʻana i ka pahu a i ʻole ka uhi kēpau ma luna o nā mea hoʻopili e kū ana.
2. Holoi me ka wai holoi.
3. Holoi me ka abrasives.
4. Hoʻokomo ʻia ka hoʻoulu ʻana i loko o 10% sulfuric acid.
5. ʻO 4-5μm ka mānoanoa o ka nickel plating ma nā mea hoʻopili protruding.
6. E holoi a wehe i ka wai mineral.
7. Hoʻomaʻamaʻa i ka hoʻonā komo gula.
8. Ka uhi gula.
9. Hoomaemae.
10. Ka maloo ana.
4. Palaki palaki
He ʻenehana electrodeposition, ʻaʻole hoʻokomo ʻia nā ʻāpana āpau i ka electrolyte i ka wā o ka hana electroplating. I loko o kēia ʻenehana electroplating, kahi palena wale nō i hoʻopili ʻia, ʻaʻohe hopena i ke koena. ʻO ka maʻamau, hoʻopaʻa ʻia nā metala maʻamau ma nā ʻāpana i koho ʻia o ka papa kaapuni i paʻi ʻia, e like me nā wahi e like me nā mea hoʻohui lihi papa. Hoʻohana pinepine ʻia ka palaki palaki i ka hoʻoponopono ʻana i nā papa kaapuni ʻōpala i nā hale kūʻai hui uila. E wīwī i kahi anode kūikawā (anode i hoʻohana ʻole ʻia, e like me ka graphite) i loko o kahi mea hoʻoheheʻe ʻia (puʻu pulupulu) a hoʻohana iā ia e lawe mai i ka hopena paʻi i kahi e pono ai ka plating.
