Hoʻolauna ireflow umu
ʻO ka umu houhoʻohana i ka uhi ʻana o ka flux, a laila hoʻomaʻamaʻa mua i ka papa kaapuni / hoʻōla ʻia, a laila hoʻohana i ka nozzle wili no ke ʻano kuʻi.Pono ka wili hao kuʻuna kuʻuna e hoʻohana i ka wiliwili kikoʻī no kēlā me kēia wahi o ka papa kaapuni, no laila, ʻoi aku ka nui o nā mea hana wili.Mīkini wili nalu kohoʻO ia ke ʻano hana ʻoihana hui o ka laina hui, nā ʻano nui o ka welding nozzle hiki ke hoʻopaʻa ʻia i ka wiliwili, maʻamau hiki ke hoʻomaikaʻi ʻia ka maikaʻi o ka welding i nā manawa he nui ma mua o ka welding manual (e pili ana i ka hoʻolālā o ka papa kaapuni kikoʻī).Ma muli o ka hoʻohana ʻana i ka polokalamu kelepona paʻa liʻiliʻi liʻiliʻi liʻiliʻi a me nā ʻano like ʻole o ka nozzle wiliwili maʻalahi, (ʻoi aku ka nui o ka pahu pahu ma kahi o 11 kg), no laila hiki ke hoʻonohonoho ʻia i ka wiliwili ma o ka papahana e pale aku i ka papa kaapuni ma lalo o kekahi mau wili a me ka hoʻoikaika ʻana a me nā mea ʻē aʻe. ʻāpana, i ʻole e hoʻopili i ka solder wela kiʻekiʻe a hana ʻino.ʻO kēia mode welding, me ka ʻole o ka hoʻohana ʻana i ka pā kuʻi maʻamau a me nā ala ʻē aʻe, kūpono loa ia no nā ʻano like ʻole, ke ʻano hana liʻiliʻi liʻiliʻi.
Loaʻa i ka reflow welding nā pono penei:
ʻO ke kūlana kiʻekiʻe o ka hana ʻana i ka welding, hiki ke ʻike i kahi kiʻekiʻe o ka welding maʻalahi.
ʻO ka mana pololei o ke kūlana hoʻoheheʻe flux a me ka nui o ka injection, ke kiʻekiʻe kiʻekiʻe o ka microwave a me ke kūlana wili.
Ka pale ʻana i ka nitrogen ma ka ʻili o ka microwave peak;ʻO ka hoʻonui ʻana i nā ʻāpana kaʻina no kēlā me kēia hui solder.
Hoʻololi wikiwiki i nā nozzles o nā nui like ʻole.
Hoʻohui ʻia ka wiliwili wahi hoʻokahi a me ka ʻenehana hoʻoheheʻe ʻana ma o ka hoʻohui puka pin sequence.
E like me nā koi hiki ke hoʻonoho solder hui shape "momona" "thin" degere.
Hiki iā ʻoe ke koho i nā ʻano modula preheating (infrared, ea wela) a me ka module preheating i hoʻohui ʻia ma luna o ka papa.
ʻAʻole mālama ʻia ka pauma electromagnetic.
Ua kūpono loa ke koho ʻana i nā mea hana no ka hoʻohana ʻana i ka solder lead-free.
Hoʻemi ka hoʻolālā modular i ka manawa mālama.
Hoʻomaka i ka welding laser
ʻO ke kumu māmā no ka hoʻoheheʻe ʻana i ka laser ʻōmaʻomaʻo he laser light-emitting diode (LLED), hiki ke nānā pono ʻia i ka hui solder ma o kahi ʻōnaehana optical.ʻO ka maikaʻi o ka welding laser ʻo ia ka hiki ke hoʻokele pololei a hoʻopaʻa i ka ikehu e pono ai no ka welding.He kūpono ia no ke kaʻina hana welding reflow a i ʻole ka hoʻohana ʻana i ka mea hoʻohui uea tin.No nā ʻāpana SMD, pono e hoʻopili mua ʻia ka paʻi solder a laila welded.Hoʻokaʻawale ʻia ke kaʻina hana kuʻi ʻana i ʻelua mau ʻanuʻu: ʻo ka mua o ka solder paste ua hoʻomehana ʻia, a ʻo ka hui solder ua hoʻomehana ʻia.Ma hope o kēlā, hoʻoheheʻe ʻia ka paʻi solder i hoʻohana ʻia no ka welding, a hoʻoheheʻe ʻia ka solder ma ka pad e hana i ka weld.Use laser generator a me ka optical focusing component welding, ikehu ikehu, kiʻekiʻe wela hoʻololi kūpono, non-contact welding, solder hiki ke solder paste a i ʻole uea tin, ʻoi aku ka maikaʻi no ka wiliwili liʻiliʻi wahi solder wahi a liʻiliʻi solder wahi mana liʻiliʻi, mālama i ka ikehu.
Nā hiʻohiʻona wiliwili laser
Ka hoʻomalu ʻana i ke kāleka kaʻa kaʻa multi-axis servo, ka pololei kūlana kiʻekiʻe.
ʻO kahi wahi laser liʻiliʻi, i ka liʻiliʻi liʻiliʻi o nā pads, loaʻa i nā mea spacing nā mea maikaʻi wili.
ʻAʻohe pili pili, ʻaʻohe pilikia mechanical, pilikia static.
ʻO Wuxi slag, hoʻemi i ka ʻōpala flux, ke kumu kūʻai haʻahaʻa.
Loaʻa nā huahana weldable i ke ʻano.
ʻO ke koho ʻana o ka solder.
Nā pōmaikaʻi o ka welding laser
No ka mea hoʻoheheʻe uila ultra-fine, nā ʻāpana uila multi-layer, ʻaʻole hiki ke hoʻohana ʻia ka "ʻenehana kuʻuna", kahi i koi ai i ka holomua wikiwiki o ka ʻenehana.ʻO ka hana ʻana o nā ʻāpana ultra-liʻiliʻi i kūpono ʻole no ke ʻano hao hao kuʻuna i hoʻopau ʻia e ka welding laser.ʻO ka welding non-contact ka mea nui loa o ka welding laser.ʻAʻohe pono e hoʻopā i ka substrate a me nā ʻāpana uila, a ʻo ka hāʻawi ʻana i ka solder wale nō e ka laser irradiation ʻaʻole ia he kaumaha kino.ʻO ka hoʻomehana maikaʻi me kahi kukuna laser polū he mea maikaʻi nō hoʻi, hiki ke hoʻohana ʻia e hoʻomālamalama i nā wahi haiki kahi hiki ʻole i ke poʻo soldering ke komo a ma nā kihi like ʻole inā ʻaʻohe mamao ma waena o nā mea pili i kahi hui paʻa.Pono e hoʻololi pinepine ʻia ke poʻo hao hao, ʻoiai ʻo nā ʻāpana ʻokoʻa no ka welding laser e pono ke hoʻololi ʻia he liʻiliʻi loa a he haʻahaʻa ke kumukūʻai mālama.
