eia ke gula a me ke keleawe ma nā papa kaapuni o nā kelepona paʻalima a me nā kamepiula. No laila, hiki i ke kumukūʻai hana hou o nā papa kaapuni i hoʻohana ʻia ma mua o 30 yuan no ka kilo. ʻOi aku ke kumukūʻai ma mua o ke kūʻai ʻana aku i nā pepa ʻōpala, nā ʻōmole aniani, a me nā hao ʻōpala.
Mai waho mai, ʻekolu kala o ka papa o waho o ka papa kaapuni: ke gula, ke kālā, a me ka ʻulaʻula māmā. ʻO ke gula ke kumu kūʻai nui loa, ʻo ke kālā ka liʻiliʻi loa, a ʻo ka ʻulaʻula māmā ka mea liʻiliʻi loa.
Hiki ke ʻike ʻia mai ka waihoʻoluʻu inā ua ʻoki ʻia nā kihi o ka mea hana lako. Eia kekahi, ʻo ke kaapuni kūloko o ka papa kaapuni he keleawe maʻemaʻe, hiki ke maʻalahi ke ʻike ʻia i ka lewa. Pono e loaʻa i ka ʻaoʻao waho ka pale pale i ʻōlelo ʻia ma luna. Wahi a kekahi poʻe he keleawe ka melemele gula, he hewa ia.
gula:
ʻO ke gula makamae loa he gula maoli. ʻOiai he ʻāpana lahilahi wale nō, ʻo ia hoʻi ma kahi o 10% o ke kumukūʻai o ka papa kaapuni. ʻO kekahi mau wahi ma kahakai o Guangdong a me Fujian ka mea kūikawā i ke kūʻai ʻana i nā papa kaapuni ʻōpala a me ka ʻili ʻana i ke gula. Nui ka waiwai.
ʻElua kumu e hoʻohana ʻia ai ke gula, ʻo kekahi no ka hoʻomaʻamaʻa ʻana i ka wiliwili, a ʻo kekahi no ka pale ʻana i ka corrosion.
ʻO ka manamana gula o ka module hoʻomanaʻo he 8 mau makahiki i hala aku nei e ʻālohilohi mau ana, inā ʻoe e hoʻololi iā ia i keleawe, aluminika, a hao paha, ʻeleʻele a make ʻole.
Hoʻohana nui ʻia ka papa gula-plated i nā pads component, nā manamana gula, a me nā shrapnel connector o ka papa kaapuni.
Inā ʻike ʻoe he kālā a pau nā papa kaapuni, pono ʻoe e ʻoki kihi. Kapa ʻia ka huaʻōlelo ʻoihana "costdown".
ʻO nā papa makuahine kelepona paʻa ka hapa nui o nā papa i uhi ʻia i ke gula, ʻoiai ʻo nā motherboards lolouila, nā leo a me nā papa kaapuni kikohoʻe liʻiliʻi ʻaʻole nā papa gula.
Kālā kala
He gula anei ka aureate a he kala ke kala?
ʻAʻole naʻe, he tini.
Ua kapa ʻia ka papa kālā ʻo ka papa pāpaʻi. ʻO ka pīpī ʻana i kahi papa tin ma ka ʻaoʻao o waho o ke kaapuni keleawe hiki ke kōkua pū i ke kūʻai ʻana. Akā ʻaʻole hiki ke hāʻawi i ka hilinaʻi pili lōʻihi e like me ke gula.
ʻAʻohe hopena o ka pā paila i nā mea i kūʻai ʻia, akā ʻaʻole lawa ka hilinaʻi no nā pads i hōʻike ʻia i ka lewa no ka manawa lōʻihi, e like me nā pad grounding a me nā kumu pine puna. Hiki ke hoʻohana lōʻihi i ka oxidation a me ka corrosion, ka hopena o ka pilina maikaʻi ʻole.
ʻO nā papa kaapuni o nā huahana kikohoʻe liʻiliʻi, me ka ʻole o nā mea ʻē aʻe, he mau papa pīni. Hoʻokahi wale nō kumu: cheap.
ʻO nā huahana kikohoʻe liʻiliʻi e like me ka hoʻohana ʻana i ka pā pā.
ʻulaʻula māmā:
OSP, kiʻiʻoniʻoni hoʻoheheʻe kūlohelohe. No ka mea, ʻo ia ka mea kūlohelohe, ʻaʻole metala, ʻoi aku ka maikaʻi ma mua o ka pulupulu ʻana.
ʻO ka hana wale nō o kēia kiʻiʻoniʻoni kūlohelohe ʻo ia ka hōʻoia ʻana ʻaʻole e hoʻoheheʻe ʻia ka foil keleawe o loko ma mua o ke kuʻi ʻana. Hoʻopau koke kēia papa kiʻiʻoniʻoni i ka wā e wela ai i ka wā wili. Hiki i ka solder ke wili i ka uwea keleawe a me nā ʻāpana.
Akā ʻaʻole ia e kū i ka corrosion. Inā ʻike ʻia kahi papa kaapuni OSP i ka lewa no nā lā he ʻumi, ʻaʻole hiki iā ia ke wili i nā ʻāpana.
Nui nā motherboards kamepiula e hoʻohana i ka ʻenehana OSP. No ka nui loa o ka ʻāpana o ka papa kaapuni, ʻaʻole hiki ke hoʻohana ʻia no ka uhi gula.
