Mai ka honua PCB,

Nui nā poʻe e hoʻohana i ke kala o ka PCB e ʻike i ka maikaʻi o ka papa.ʻO ka ʻoiaʻiʻo, ʻaʻohe pili o ke kala o ka motherboard me ka hana o ka PCB.

ʻO ka papa PCB, ʻaʻole ʻo ka kiʻekiʻe o ka waiwai, ʻoi aku ka maʻalahi o ka hoʻohana.

ʻO ke kala o ka ʻili PCB ʻo ia ke kala o ka pale kūʻai.Hiki i ka solder resistance ke pale i ka hiki ʻana mai o ka soldering hewa o nā ʻāpana, a hoʻopaneʻe i ke ola lawelawe o ka hāmeʻa, a pale i ka oxidation a me ka corrosion o ke kaapuni mea.

Inā maopopo iā ʻoe nā papa PCB o nā hui nui e like me Huawei a me ZTE, e ʻike ʻoe he ʻōmaʻomaʻo ke kala.ʻO kēia no ka mea ʻo ka ʻenehana ʻōmaʻomaʻo ka mea ʻoi loa a maʻalahi.

Ma waho aʻe o ka 'ōmaʻomaʻo, hiki ke wehewehe ʻia ke kala o PCB e like me "nā bele a me nā kīwī": keʻokeʻo, melemele, ʻulaʻula, uliuli, matte kala, a hiki i ka chrysanthemum, poni, ʻeleʻele, ʻōmaʻomaʻo ʻōmaʻomaʻo, etc. pono e hana i nā huahana kukui ʻO nā kala i hoʻohana ʻia, a me ka hoʻohana ʻana i nā waihoʻoluʻu ʻē aʻe, ka hapa nui no ka hoʻopaʻa inoa ʻana i nā huahana.Ma ka pae holoʻokoʻa o ka hui mai R&D a hiki i ka pae ʻana o ka huahana, ma muli o nā hoʻohana like ʻole o ka PCB, hiki i ka papa hoʻokolohua ke poni, ʻulaʻula ka papa kī, a ʻeleʻele nā ​​papa o loko o ke kamepiula, kahi i kaha ʻia. ma ke kala.

ʻO ka papa PCB maʻamau ka papa'ōmaʻomaʻo'ōmaʻomaʻo, i kapaʻia hoʻi kaʻaila'ōmaʻomaʻo.ʻO kāna ink solder mask ka mea kahiko loa, ʻoi aku ka liʻiliʻi a kaulana loa.Ma waho aʻe o ka ʻenehana makua, he nui nā pono o ka aila ʻōmaʻomaʻo:

I ka hana PCB, ʻo ka hana ʻana o nā huahana uila e pili ana i ka hana papa a me ka patching.I ka wā o ke kaʻina hana, he nui nā kaʻina e hele ai i loko o ka lumi kukui melemele, a ʻo ka papa PCB ʻōmaʻomaʻo ka hopena ʻike maikaʻi loa i ka lumi kukui melemele;ʻO ka lua, i ka hana ʻana i ka SMT patch, hoʻohana ʻia ka tin.Pono nā ʻanuʻu o, patching a me AOI calibration i ka optical positioning calibration, a ʻoi aku ka maikaʻi o ka mea kani ʻōmaʻomaʻo lalo no ka ʻike.

ʻO ka ʻāpana o ka nānā ʻana e hilinaʻi i nā limahana e nānā (akā i kēia manawa ka hapa nui o lākou e hoʻohana i ka hoʻāʻo lele lele ma mua o ka manual), e nānā ana i ka papa ma lalo o ke kukui ikaika, ʻoluʻolu ka ʻōmaʻomaʻo i nā maka.ʻOi aku ka maikaʻi o nā PCB Green, a ʻaʻole e hoʻokuʻu i nā kinoea ʻawaʻawa ke hana hou ʻia lākou i nā wela kiʻekiʻe.

ʻO nā kala PCB ʻē aʻe, e like me ka uliuli a me ka ʻeleʻele, ua doped ʻia me ka cobalt a me ke kalapona, kēlā me kēia, no ka mea he nāwaliwali ko lākou conductivity uila, a aia kahi pilikia o ka pōkole pōkole.

E lawe i ka papa ʻeleʻele i laʻana.I ka hana ʻana, hiki i ka papa ʻeleʻele ke kumu i ka ʻokoʻa o ka waihoʻoluʻu ma muli o ke kaʻina hana a me nā pilikia maka, ka hopena i kahi helu kīnā PCB kiʻekiʻe.ʻAʻole maʻalahi ka ʻike ʻana i nā ʻāpana o ka papa kaapuni ʻeleʻele, kahi e hoʻonui ai i ka paʻakikī no ka mālama ʻana a me ka debugging ma hope.ʻAʻole hoʻohana nā hale hana PCB i nā PCB ʻeleʻele.ʻOiai ma ke kahua o ka ʻoihana koa a me ka mana ʻoihana, nā huahana me nā koi kiʻekiʻe kiʻekiʻe e hoʻohana i nā substrate PCB ʻōmaʻomaʻo.

A laila, e kamaʻilio e pili ana i ka hopena o ka kala ink solder mask ma ka papa?

No ka huahana i hoʻopau ʻia, ʻike nui ʻia ka hopena o nā ʻīnika like ʻole ma ka papa i ka hiʻohiʻona, ʻo ia hoʻi, he maikaʻi a ʻaʻole paha.Eia kekahi laʻana,ʻo ka'ōmaʻomaʻo ka lā'ōmaʻomaʻo, ka'ōmaʻomaʻo'ōmaʻomaʻo, ka'ōmaʻomaʻo'ōmaʻomaʻo, ka'ōmaʻomaʻo matt, a me nā mea'ē aʻe, ua māmā loa ke kala, ua maʻalahi kaʻikeʻana i ka plug ʻO keʻano o ka papa ma hope o ke kaʻina hana pukaʻaʻole maikaʻi, aʻo kekahi mau mea hana' ʻAʻole maikaʻi ka ʻīnika, pilikia ka lākiō resin a me ka wai, aia nā pilikia e like me nā ʻōhū, a hiki ke ʻike ʻia nā loli liʻiliʻi o ke kala;ʻike nui ʻia ka hopena i nā huahana semi-finished Ma ke ʻano o ka paʻakikī o ka hana ʻana, he paʻakikī kēia pilikia e wehewehe.Loaʻa i nā ʻīnika kala like ʻole nā ​​kaʻina kala like ʻole, e like me ka hoʻoheheʻe ʻana i ka electrostatic, ka hoʻoulu ʻana, a me ka paʻi pale.ʻOkoʻa nō hoʻi ka ratio inika.ʻO ka hewa liʻiliʻi e ʻike ʻia ke kala.pilikia.

ʻOiai ʻaʻohe hopena o ke kala o ka inika ma ka papa PCB, ʻo ka mānoanoa o ka inika ka hopena nui i ka impedance, ʻoi aku hoʻi no ka papa wai-gula, nona ka mana koʻikoʻi i ka mānoanoa o ka inika;ʻO ka mānoanoa a me nā'ōhū o ka'īnikaʻulaʻula he mea maʻalahi ka hoʻomaluʻana, a me ka uhiʻulaʻula i uhiʻia Ma ka laina, hiki ke uhiʻia kekahi mau hemahema, aʻoi aku ka nani o ka helehelena, akāʻo ka meaʻino,ʻoi aku ka pipiʻi o ke kumukūʻai.I ke kiʻi ʻana, ʻoi aku ka paʻa o ka ʻulaʻula a me ka melemele, a ʻo ke keʻokeʻo ka mea paʻakikī loa e kāohi.

No ka hōʻuluʻulu ʻana, ʻaʻohe hopena o ke kala i ka hana o ka papa i hoʻopau ʻia, a he liʻiliʻi liʻiliʻi ka hopena ma ka hui PCB a me nā loulou ʻē aʻe;i ka PCB hoʻolālā, kēlā me kēia kiko'ī i loko o kēlā me kēia loulou ua strictly hoomaluia, a me ka PCB papa lilo Ke kī i ka maikai papa.ʻO nā motherboards PCB o nā kala like ʻole no ke kūʻai aku ʻana i nā huahana.ʻAʻole ʻōlelo ʻia ʻoe e hoʻohana i ke kala ma ke ʻano he mea nui i ka hana PCB.
