He aha ka ʻokoʻa ma waena o ka hawewe koho ʻana a me ka hawewe maʻamau?

Mīkini hoʻoheheʻe naluʻO ka papa kaapuni holoʻokoʻa a me ka hoʻopili ʻana i ka ʻili e pili ana i ka ʻili o ka ʻili o ka solder piʻi kūlohelohe e hoʻopau i ka wili.No ka nui o ka wela a me ka papa kaapuni multilayer, paʻakikī ka mīkini hoʻoheheʻe nalu e hoʻokō i nā koi komo tin.Mīkini wili nalu kohoʻokoʻa, ʻo ka nozzle welding he nalu tin dynamic, ʻo kona ikaika ikaika e pili pono i ke komo ʻana o ka tin vertical ma loko o ka lua;ʻOi loa no ka hoʻoheheʻe ʻana i ke alakaʻi ʻole, no ka maikaʻi ʻole o ka wettability, pono ka nalu ikaika a ikaika.Eia kekahi, ʻaʻole maʻalahi ka puʻupuʻu hawewe kahe ikaika i ke koena o ka oxide, kahi e kōkua ai i ka hoʻomaikaʻi ʻana i ka maikaʻi wili.

ʻAʻole kiʻekiʻe ke kiʻekiʻe o ka hoʻoheheʻe ʻana o ka mīkini hoʻoheheʻe hawewe koho, no ka mea, ʻo ka wiliwili koho ka mea nui no ka papa PCB precision kiʻekiʻe, ʻaʻole hiki ke wili ʻia ka wili nalu maʻamau.He kuʻuna nalu kuʻuna inā ʻaʻole hiki ke hoʻopau ʻia ma o ka hui pū ʻana o ka lua (i wehewehe ʻia i kekahi mau huahana kūikawā, e like me ka uila uila, nā papa aerospace, a me nā mea ʻē aʻe), i kēia manawa hiki ke hoʻohana i ka papahana no kēlā me kēia mea kūʻai aku i ke koho o ka mana pololei, kūpaʻa ma mua o ka wili lima. , lopako soldering, wela, kaʻina hana, welding parameter, like controllable, repeatable control;He kūpono no kēia manawa ma o ka hole welding hou aku a ʻoi aku ka liʻiliʻi, welding intensive huahana.ʻOi aku ka haʻahaʻa o ka hana ʻana o ka welding nalu koho ma mua o ka welding nalu maʻamau (ʻoiai inā he 24 mau hola), ʻoi aku ka kiʻekiʻe o ka hana a me ka mālama ʻana, a ʻo ke kī i ka hopena electrode e nānā i ka nozzle.

ʻO ka mīkini hoʻoheheʻe nalu koho nui ka manaʻo nui:
1. Kūlana Sprinkler.Paʻa ke kahe o ke kī.ʻAʻole kiʻekiʻe a haʻahaʻa paha nā nalu.
2. ʻAʻole pono e lōʻihi ka pine kuʻi, ʻo ka lōʻihi loa ka pine e alakaʻi i ka nozzle deviation, pili i ke kahe kahe o ka tin.

Mīkini hoʻoheheʻe nalu
Kaʻina hana maʻalahi me ka welder nalu:
ʻO ka mua, hoʻoheheʻe ʻia kahi papa o ka flux ma ka ʻaoʻao lalo o ka pā i hoʻopaʻa ʻia.ʻO ke kumu o ka flux e hoʻomaʻemaʻe a hoʻomākaukau i nā ʻāpana a me ka PCBS no ka wili.
No ka pale ʻana i ka haʻalulu wela, e ʻoluʻolu e hoʻomaha mālie i ka pā ma mua o ka wili ʻana.
A laila wili ka PCB i ka pā ma nā nalu o ka solder hehee.

ʻOiai ʻaʻole kūpono ka mīkini hoʻoheheʻe nalu no ka mamao maikaʻi loa i koi ʻia no ka nui o nā papa kaapuni o kēia mau lā, kūpono mau ia no nā papahana he nui me nā ʻāpana ma waena o ka puka maʻamau a me kekahi mau mea i kau ʻia ma luna.I ka wā ma mua, ʻo ka hoʻoheheʻe ʻana i ka nalu ke ʻano hana nui i hoʻohana ʻia ma ka ʻoihana no ka mea ʻoi aku ka nui o ka PCBS i kēia manawa a ʻo ka hapa nui o nā ʻāpana i loko o ka lua i puʻunaue ʻia ma PCB.
