Mīkini wili nalu kohohāʻawi i kahi ala kuʻihao hou, i loaʻa nā mea maikaʻi ʻole ma mua o ka welding manual, kuʻunamīkini hoʻoheheʻe nalua puka pukareflow umu.Eia nō naʻe, ʻaʻole hiki ke kūpono ke ʻano kuʻi ʻana, a loaʻa pū kekahi mau "palena" i hoʻoholo ʻia e nā ʻano mea hana.
1. Hiki ke neʻe wale i luna a i lalo ka nozzle hoʻoheheʻe hawewe koho, ʻaoʻao hema a ʻākau, ʻaʻohe ʻike o 3 d rotation, selective wave soldering wave crest is vertical, not horizontal wave (lateral wave). ma ka microwave lua paia, insulator a vertically hoʻokomo 'ia ma luna o ka motherboard 'āpana ma ka pai 'ia kaapuni papa mea paakiki e hoʻokō kuʻihao, No ka rf konohiki hui a me ka lehulehu-core hui uwea hiki ole ke hoʻokō kuʻihao, 'oiaʻiʻo, ka kuʻuna nalu soldering a reflow kuʻihao. hiki ole ke hookoia;ʻOiai me ka welding robot, aia kekahi mau "palena".
2. ʻO ka lua o ka palena o ka nalu koho ʻana ʻo ia ka hua.Kuʻuna nalu soldering ka holoʻokoʻa papa kaapuni hoʻokahi-manawa kuʻihao, koho o ka kuʻihao he wahi kuʻihao a liilii nozzle kuʻihao, akā, me ka hoʻomohala wikiwiki o ka uila 'oihana, ma o ka lua mea emi a emi, productivity ma o ka modularization manao o selective hawewe soldering. Ua hoʻomaikaʻi ʻia ka multi-cylinder parallel, ʻoi aku ka nui o ka ʻenehana Kelemania, ʻo ka hiki ke hana he hapa.
3. Hoʻopili ʻana i ka nalu koho ADAPTS i ka spacing pine ʻāpana (ka mamao waena).I loko o ka hui kiʻekiʻe kiʻekiʻe o ka PCBA, e liʻiliʻi a liʻiliʻi ana ke kaawale o nā mea hoʻopili uila a me nā ʻāpana ʻāpana pālua (DIP), ka mamao o nā mea hoʻopili uila a me nā pine pālua-in-line integrated circuits (DIP) (ka mamao waena). ua ho'ēmiʻia mai ka 1.27mm maʻamau i ka 0.5mm a iʻole ka liʻiliʻi;Lawe mai kēia i nā luʻi i ke kuʻekuʻe nalu kuʻuna a me ke kuʻekuʻe nalu koho.Ke emi ka mamao o ka pine o ka mea hoʻohui uila ma mua o 1.0mm a i ʻole 0.5mm, e kaupalena ʻia ke kuʻi ʻana ma kahi kikoʻī e ka nui o ka nozzle crest, a ʻo ka wili kauo e hoʻonui i ka hemahema o ka hoʻopili ʻana i kahi wahi.No laila, ua hōʻike ʻia nā hemahema o ka soldering nalu koho i ka hui kiʻekiʻe.
4. Ke hoʻohālikelike ʻia me ke kuʻi ʻana o ka nalu maʻamau, ʻoi aku ka liʻiliʻi o ka mamao kuʻi ʻana o nā mea hoʻoheheʻe koho koho ma mua o ka nalu maʻamau ma muli o kāna hana kūikawā o nā ʻāpana solder "thin".Hiki ke hoʻokō ʻia ka wili hilinaʻi no nā ʻāpana ma waena o ka puka me ka mamao o ka pine i ʻoi aku ma mua o a i ʻole like me 2mm;No nā ʻāpana o loko o ka puka me ka mamao pin o 1 ~ 2mm, pono e hoʻopili ʻia ka hana kuʻi ʻana o nā mea hana no ka hoʻokō pono ʻana i ka wiliwili;No nā ʻāpana o loko o ka puka me ka mamao pin ma lalo o 1mm, pono ia e hoʻolālā i kahi nozzle kūikawā a hoʻohana i kahi kaʻina hana kūikawā e hoʻokō ai i ka wili kīnā ʻole.
5. Inā ʻoi aku ka liʻiliʻi o ka mamao waena o ka mea hoʻopili uila ma mua o ka 0.5mm, e hoʻohana i ka ʻenehana hoʻopili kelepona ʻole.
Loaʻa nā koi koʻikoʻi ma ka hoʻolālā PCB a me ka ʻenehana no ka hoʻoheheʻe ʻana i ka nalu koho, akā aia nō kekahi mau hemahema wili, e like me nā pahu tin, ʻo ia ka mea paʻakikī loa e hoʻoponopono.
6. He pipiʻi ka lako, he $200,000 ke kumu kūʻai o nā mea kūʻai haʻahaʻa haʻahaʻa haʻahaʻa, a he haʻahaʻa ka maikaʻi o ke kuʻi nalu koho.I kēia manawa, ʻo ka mea kūʻai nalu koho ʻoi loa e koi i kahi pōʻai 5s, a no ka PCB me nā ʻāpana he nui ma loko o ka lua, ʻaʻole hiki iā ia ke hoʻomau i ka beat hana i ka hana nui, a nui ke kumukūʻai.
