ʻO ke kuleana o ka mīkini welding nalu

ʻO ka mīkini wili nalu he mīkini maʻamau a me nā mea hana i ka ʻoihana hana uila.ʻO ka ʻōlelo maʻamau, ʻo ia ka mea nui no nā mea uila plug-in i hoʻokomo ʻia i ka papa kaapuni pcb uila ma hope o ke kūʻai ʻana.ʻO ka mīkini hoʻoheheʻe nalu me ka metala hoʻopiha wai e pono ai i ke kaʻina o ka hoʻoheheʻe ʻana i ka nalu ʻelua o ka papa paʻi a me ka hoʻoheheʻe ʻana i ka nalu hoʻokahi o ka papa kaapuni SMC.ʻO ka hoʻoheheʻe ʻana o Crest e pili ana i ka mea hoʻoheheʻe palupalu palupalu (lead tin alloy), ka pauma uila a i ʻole electromagnetic pump jet i ka hoʻolālā ʻana o ka solder crest. me nā mea uila ma o ka solder crest, E mālama i ka wiliwili hikiwawe o nā mea hana mechanical a me nā pilina uila ma waena o nā wēlau o nā mea uila a i ʻole nā ​​pine a me nā pad papa i paʻi ʻia.

Hoʻohana pono ʻia ʻo Wave crest welder (wave crest welder) e like me ka hoʻokomo kuʻuna ma waena o ka puka o ka ʻenehana hoʻoponopono uila i paʻi ʻia, a me ka hui ʻana o ka ʻili a me ka hoʻokomo ʻana o nā mea uila i hui pū ʻia.Hiki ke hoʻohana ʻia nā mea uila i hoʻohui ʻia i ka ʻili i ke kaʻina hoʻoheheʻe nalu, ʻo ia ka ʻāpana ʻāpana ʻāpana a me nā ʻāpana cylindrical chip, SOT a me nā Sops liʻiliʻi.I kēia manawa, ʻo ke kī maʻamau ma Kina, ʻo ia nā ʻano: mīkini wili nalu ʻauʻau, mīkini wili nalu lua, mīkini wili nalu liʻiliʻi a me ka mīkini wili nalu kepau.ʻO kāna kaʻina hana: e hoʻokomo i nā ʻāpana i loko o nā lua ʻē aʻe → pre-coating flux → pre-drying (ka wela 90-1000C, lōʻihi 1-1.2m) → ka nalu nalu (220-2400C) → ka wehe ʻana i nā wāwae plug-in keu → nānā. .

Ke hoʻohana ʻia ka papa i paʻi ʻia no ka hāʻawi ʻana (a i ʻole ka paʻi paʻi ʻana) i ka mea hoʻopili, kau ʻana, hoʻomaloʻo a hoʻokomo i nā mea uila ma loko o ka lua e hana ʻia i mua mai ka hopena o ke kahawai o ka mīkini wili nalu me ke kāʻei conveyor, e like me ka flux polyurethane foaming (a i ʻole. sprayer) slot, ka pad ma ka ʻili o lalo o ka papa i paʻi ʻia, nā ʻāpana honua a pau o nā mea uila a me ka ʻili o ka pine ua uhi ʻia me kahi ʻāpana lahilahi o ka flux.Me ka hana kāʻei conveyor, ka papa i paʻi ʻia i loko o ka wahi hoʻomehana, hoʻoheheʻe ʻia ka mea hoʻoheheʻe organik i loko o ka flux, hoʻomaka ka resin a me ka mea hana i loko o ka flux e hoʻoheheʻe a ikaika, ka papa kuʻi ʻana o ka papa i paʻi ʻia, ka mea uila uila a me ka wāwae. hoʻoneʻe ʻia ka ʻili o ke kiʻi ʻoniʻoni ʻona ea a me nā mea haumia ʻē aʻe;I ka manawa like, loaʻa i nā papa i paʻi ʻia a me nā mea uila e lawa ka preheating.Ke hoʻomau nei ka neʻe ʻana o ka papa paʻi i mua, me ka ʻaoʻao lalo o ka papa i paʻi ʻia e hele mua i ka nalu mua o ka mea hoʻoheheʻe ʻia.ʻO ka nalu solder mua, he nalu kūpikipikiʻo (vibrating or turbulent) e pā ana i nā pad a pau, nā welau uila a me nā pine ma ka ʻaoʻao lalo o ka papa i paʻi ʻia.ʻO ka hoʻoheheʻe solder pulu a diffuses i ka passivation o ke kila kuhiliʻole i hoʻomaʻemaʻe ʻia e ka flux.Ma hope mai, hoʻohana ka ʻaoʻao lalo o ka papa i paʻi ʻia i ka nalu hoʻoheheʻe ʻia aʻe, ʻo ka nalu solder ʻelua ka nalu maʻemaʻe, ʻo ka nalu maʻemaʻe e hoʻokaʻawale i ke alahaka ma waena o ka pine a me ka hopena wili, a wehe i ka piko huki (icicle) nā hemahema.Ke hoʻomau ka holo ʻana o ka papa i paʻi ʻia i mua mai ka nalu solder lua, hoʻohua mai ka hoʻoluʻu kūlohelohe i nā hui solder, ʻo ia hoʻi, ka hoʻopili piha ʻana.

ʻO ka mīkini wili nalu nalu no nā ʻoihana hana uila he mea pono ʻole nā ​​mīkini a me nā mea hana, ʻo ka mākeke kūʻai kūʻai ʻana i nā mīkini wiliwili i kēia manawa he nui loa, akā he liʻiliʻi nā mea hana maʻamau, kūʻai i ka lawelawe ma hope o ke kūʻai aku e hōʻoia i ka mīkini welding nalu a i ʻole e ʻimi i kahi. mea hana mīkini wili nalu nui.ʻO Chengyuan Automation kāu koho maikaʻi loa.
