1. No ke aha i loaʻa ai ka BGA i loko o ka lua mask solder?He aha ke kūlana hoʻokipa?
Re: ʻO ka mea mua, ʻo ka solder mask plug plug e mālama i ke ola lawelawe o ka via, no ka mea, ʻoi aku ka liʻiliʻi o ka puka i koi ʻia no ke kūlana BGA, ma waena o 0.2 a me 0.35mm.ʻAʻole maʻalahi ka hoʻomaloʻo a hoʻoheheʻe ʻia kekahi syrup, a maʻalahi ke waiho i nā koena.Inā ʻaʻole hoʻokomo ka mask solder i ka puka a ʻaʻole i piha ka plug, aia ke koena o nā mea ʻē a i ʻole nā pahu tin i ka hana ma hope e like me ke kāpī ʻana i ka tin a me ke gula immersion.I ka wā e wela ai ka mea kūʻai i ka ʻāpana i ka wā e kūʻai aku ai i ka wela, e kahe ana nā mea ʻē a i ʻole nā pahu tin i loko o ka lua a pili i ka ʻāpana, e hoʻopilikia ai i ka hana ʻana, e like me ka wehe a me ka pōkole pōkole.Aia ka BGA i loko o ka lua huna huna A, pono e piha ʻo B, ʻaʻole ʻae ʻia ka ʻulaʻula a i ʻole ke keleawe hoʻopunipuni, C, ʻaʻole piha loa, a ʻoi aku ka kiʻekiʻe o ka protrusion ma mua o ka pad e kūʻai ʻia ma hope o ia (e pili ana i ka ʻāpana kau ʻana Effect). 
2. He aha ka ʻokoʻa ma waena o ke aniani papa ʻaina o ka mīkini hoʻolaha a me ke aniani maʻamau?No ke aha i like ʻole ai ka reflector o ke kukui hoʻolaha? Re: ʻAʻole e hana ke aniani papa ʻaina o ka mīkini hoʻolaha i ka hoʻohuli ʻana i ka māmā ke hele ka mālamalama.Inā palahalaha a maʻalahi ka reflector o ke kukui hoʻolaha, a laila i ka wā e ʻā ai ke kukui ma luna o ia, e like me ke kumu o ka mālamalama, hoʻokahi wale nō kukui i hoʻomālamalama ʻia ma ka papa e ʻike ʻia.Inā he convex a ʻaʻole like ka lua e like me ke kukui ʻO ke kumu ʻo ia ka mālamalama e ʻā ana i nā recesses a me ka mālamalama e ʻā ana i nā protrusions e hana i nā kukuna he nui i hoʻopuʻi ʻia o ka mālamalama, e hana ana i nā kukui irregular akā like ʻole ma ka papa e ʻike ʻia, e hoʻomaikaʻi i ka hopena o ka ʻike. 
3. He aha ka hoʻomohala ʻaoʻao?He aha nā hopena maikaʻi ma muli o ka hoʻomohala ʻaoʻao? Re: ʻO ka ʻāpana ākea ma lalo o ka ʻāpana kahi i kūkulu ʻia ai ka ʻaila ʻōmaʻomaʻo ma kekahi ʻaoʻao o ka puka aniani solder mask i kapa ʻia ʻo ka hoʻomohala ʻaoʻao.Ke ulu nui ka ʻaoʻao, ʻo ia ka mea ʻoi aku ka nui o ka ʻaila ʻōmaʻomaʻo o ka ʻāpana i hoʻomohala ʻia a pili pū me ka substrate a i ʻole ka ʻili keleawe, a ʻoi aku ka nui o ke degere o ka dangling i hana ʻia e ia.ʻO ke kaʻina hana e like me ka hoʻoulu ʻana i ka tin, ke kuʻi ʻana i ka tin, ke gula Immersion a me nā ʻāpana ʻē aʻe e ulu ana e hoʻouka ʻia e ka wela kiʻekiʻe, ke kaomi a me kekahi mau meaʻai i ʻoi aku ka ikaika i ka ʻaila ʻōmaʻomaʻo.E hāʻule ka ʻaila.Inā loaʻa kahi alahaka ʻaila ʻōmaʻomaʻo ma ke kūlana IC, e hana ʻia ia i ka wā e hoʻokomo ai ka mea kūʻai aku i nā ʻāpana wili.E hana i ka alahaka pōkole kaapuni.
4. He aha ka hōʻike ʻana i ka mask solder maikaʻi ʻole?He aha nā hopena maikaʻi e hana ai? Re: Ma hope o ka hana ʻia ʻana e ke kaʻina hana solder mask, ʻike ʻia i nā pads o nā ʻāpana a i ʻole nā wahi e pono ai ke soldered i ka hana hope.I ka wā o ka solder mask alignment/exposure kaʻina, kumu ia e ka pale māmā a i ʻole ka pilikia o ka ikehu a me ka hana.ʻO ka waho a i ʻole ka ʻaila ʻōmaʻomaʻo a pau i uhi ʻia e kēia ʻāpana e ʻike ʻia i ka mālamalama e hoʻoulu ai i kahi hopena hoʻohui.I ka wā o ka hoʻomohala ʻana, ʻaʻole e hoʻoheheʻe ʻia ka ʻaila ʻōmaʻomaʻo ma kēia ʻāpana e ka hopena, a ʻaʻole hiki ke hōʻike ʻia ka waho a i ʻole nā papa āpau e kūʻai ʻia.Kapa ʻia kēia ʻano solering.Hōʻike maikaʻi ʻole.ʻO ka hōʻike maikaʻi ʻole ka hopena i ka hiki ʻole ke kau ʻana i nā ʻāpana i ke kaʻina hana aʻe, ʻino ke kūʻai aku, a, i nā hihia koʻikoʻi, kahi kaapuni hāmama. 5. No ke aha mākou e pono ai e hoʻomaʻamaʻa mua i ka pā wili no ka wili a me ka mask solder? Re: 1. Aia ma ka ili o ka papa kaapuni ka papapa a me ka pahu me ke keleawe i uhi mua ia ma hope o ka metallization puka.No ka hoʻopaʻa paʻa ʻana ma waena o ka kiʻiʻoniʻoni maloʻo a me ka ʻili o ka substrate, pono ʻole ka ʻili o ka substrate me ka ʻole o nā papa oxide, nā ʻaila ʻaila, nā manamana lima a me nā lepo ʻē aʻe, ʻaʻohe burrs wili, a ʻaʻohe mea paʻa.I mea e hoʻonui ai i ka wahi pili ma waena o ke kiʻi maloʻo a me ka ʻili o ka substrate, pono nō hoʻi ka substrate e loaʻa i kahi micro-rough surface.I mea e hoʻokō ai i nā koi ʻelua i luna, pono e hoʻomaʻamaʻa pono ka substrate ma mua o ke kiʻi ʻana.Hiki ke hōʻuluʻulu ʻia nā ʻano lapaʻau e like me ka hoʻomaʻemaʻe mechanical a me ka hoʻomaʻemaʻe kemika.
2. He ʻoiaʻiʻo ka loina like no ka mask solder like.ʻO ka wili ʻana i ka papa ma mua o ka solder mask ʻo ia ka wehe ʻana i kekahi mau papa oxide, nā ʻaila ʻaila, nā manamana lima a me nā lepo ʻē aʻe ma ka ʻili o ka papa, i mea e hoʻonui ai i ka wahi pili ma waena o ka ink solder mask a me ka ʻili papa a paʻa.Pono ka ʻili o ka papa e loaʻa kahi ʻili liʻiliʻi (e like me ke kaʻa no ka hoʻoponopono ʻana i ke kaʻa, pono e hoʻoheheʻe ʻia ka huila i kahi ʻili ʻōpala i mea e hoʻopaʻa maikaʻi ai me ke kāpili).Inā ʻaʻole ʻoe e hoʻohana i ka wili ma mua o ke kaapuni a i ʻole solder mask, ʻo ka ʻili o ka papa e paʻi ʻia a paʻi ʻia he mau ʻāpana oxide, nā ʻaila hinu, a me nā mea ʻē aʻe, e hoʻokaʻawale pololei ia i ka mask solder a me ke kiʻi ʻoniʻoni mai ka ʻili papa. kaʻawale, a hāʻule ke kiʻiʻoniʻoni ma kēia wahi a ʻili i ka hana hope. 6. He aha ka viscosity?He aha ka hopena o ka viscosity o ka solder mask ink i ka hana PCB? Re: ʻO ka viscosity kahi ana o ka pale ʻana a i ʻole ka pale ʻana i ke kahe.ʻO ka viscosity o ka solder mask ink he mana nui i ka hana ʻana o PCB .Ke kiʻekiʻe loa ka viscosity, maʻalahi ka hana ʻole ʻana i ka ʻaila a i ʻole ka paʻa i ka ʻupena.Ke haʻahaʻa loa ka viscosity, e piʻi ka wai o ka inika ma ka papa, a maʻalahi ke hoʻokomo i ka ʻaila i loko o ka lua.A puke sub-aila kūloko.ʻO ka ʻōlelo pili, ke ʻoi aku ka mānoanoa o ka papa keleawe o waho (≥1.5Z0), pono e hoʻomalu ʻia ka viscosity o ka inika e haʻahaʻa.Inā kiʻekiʻe ka viscosity, e emi ana ka wai o ka inika.I kēia manawa, ʻo ka lalo a me nā kihi o ke kaapuni ʻaʻole ia e ʻaila a ʻike ʻia. 7. He aha nā mea like a me nā ʻokoʻa ma waena o ka hoʻomohala maikaʻi ʻole a me ka ʻike maikaʻi ʻole? Re: Nā helu like: a.Aia ka ʻaila solder mask ma ka ʻili kahi e pono ai ke soldered ke keleawe/gula ma hope o ka solder mask.ʻO ke kumu o ka b ua like nō ia.ʻO ka manawa, ka mahana, ka manawa hoʻolaha a me ka ikaika o ka pepa bakena he mea like. ʻOkoʻa: ʻO ka wahi i hana ʻia e ka ʻike maikaʻi ʻole ʻoi aku ka nui, a ʻo ke koena solder mask mai waho a i loko, a ʻano like ka laulā a me ka Baidu.ʻIke ʻia ka hapa nui o lākou ma nā pad porous.ʻO ke kumu nui, ʻo ka ʻīnika ma kēia ʻāpana i ʻike ʻia i ke kukui ultraviolet.ʻAlohi ke kukui.ʻO ke koena o ka ʻaila solder mask mai ka hoʻomohala maikaʻi ʻana he ʻoi aku ka lahilahi ma lalo o ka papa.ʻAʻole nui kona ʻāpana, akā hana ʻia kahi ʻano kiʻiʻoniʻoni lahilahi.ʻO kēia ʻāpana o ka inika ma muli o nā kumu hoʻōla ʻokoʻa a ua hana ʻia mai ka ʻīnika papa honua.He ʻano hierarchical, e ʻike pinepine ʻia ma kahi pā puka.
8. No ke aha e hoʻopuka ai ka mask solder i nā ʻōhū?Pehea e pale aku ai? Re: (1) Hoʻohui pinepine ʻia ka ʻaila solder mask a hana ʻia e ka mea nui o ka inika + curing agent + diluent.I ka hui ʻana a me ka hoʻoulu ʻana o ka ʻīnika, e noho kekahi ea i loko o ka wai.Ke hele ka ʻīnika ma ka ʻōpala, ʻo ka uea Ma hope o ka hoʻopili ʻia ʻana o nā ʻupena i kekahi i kekahi a kahe i luna o ka papa, i ka wā e hālāwai ai lākou i ka mālamalama ikaika a i ʻole ka wela like i ka manawa pōkole, e kahe wikiwiki ke kinoea i loko o ka inika me ka wikiwiki like o ka. ka inika, a e hoʻoheheʻe loa ia.
(2), he haiki loa ka laina laina, he kiʻekiʻe loa nā laina, ʻaʻole hiki ke paʻi ʻia ka ʻīnika solder mask ma ka substrate i ka wā o ka paʻi ʻana i ka pale, ka hopena i ke alo o ka ea a i ʻole ka wai ma waena o ka ink solder mask a me ka substrate, a me ka Hoʻomaʻamaʻa ʻia ke kinoea e hoʻonui a hoʻoulu i nā ʻōhū i ka wā o ka mālama ʻana a me ka hoʻolaha ʻana.
(3) ʻO ka laina hoʻokahi ke kumu nui o ka laina kiʻekiʻe.Ke hoʻopili ka squeegee me ka laina, piʻi ka huina o ka squeegee a me ka laina, no laila ʻaʻole hiki ke paʻi ʻia ka ʻīnika solder mask i lalo o ka laina, a aia ke kinoea ma waena o ka ʻaoʻao o ka laina a me ka mask solder. inika , E hana ʻia kahi ʻano ʻōhū liʻiliʻi i ka wā e wela ai.
Kāohi:
a.ʻO ka inika i hoʻonohonoho ʻia he paʻa no kekahi manawa ma mua o ka paʻi ʻana,
b.Paʻa nō hoʻi ka papa i paʻi ʻia no kekahi manawa no laila e hoʻololi mālie ke kinoea i loko o ka ʻīnika ma ka ʻili o ka papa me ke kahe ʻana o ka inika, a laila lawe ʻia no kekahi manawa.E kālua i ka mahana.
