ʻO wai ka mea kūpono no ka hana ʻana o ka hui PCB ma waena o ka welding koho a me ka soldering nalu?

Hoʻohana maʻamau ʻia ka welding koho a me ka soldering naluʻO ka hōʻoia ʻana o ka hui PCB.Eia nō naʻe, loaʻa i kēlā me kēia o kēia mau ʻano nā pono a me nā hemahema.E nānā kākou i ka wiliwili koho a me ka hoʻoheheʻe nalu – ʻo wai ka mea i kūpono no ka hoʻoili ʻana i ka chip SMT, hōʻoia a me ka hui?

Kuʻo nalu

ʻO ka nalu ʻana, ʻike pinepine ʻia ʻo reflow soldering, e hana ʻia i loko o kahi ea kinoea pale, no ka mea, ua ʻike ʻia ʻo ka hoʻohana ʻana i ka nitrogen hiki ke hōʻemi nui i ka hiki ke hoʻoheheʻe ʻia.

ʻO ke kaʻina hana hoʻoheheʻe hawewe:

1. E hoʻopili i kahi kapa o ka flux e hoʻomaʻemaʻe a hoʻomākaukau i ka hui.Pono kēia no ka mea e pili ana nā haumia i ke kaʻina hana kuʻi.

2. Kaapuni papa preheating.E ho'ā 'o ia i ka flux a me ka hō'oia 'a'ole pili ka papa i ka ha'alulu wela.

3. Hele ka PCB i ka mea hooheheeia.I ka neʻe ʻana o ka papa kaapuni ma ke kaʻa alakaʻi crest, ua hoʻokumu ʻia kahi pilina uila ma waena o nā alakaʻi ʻāpana uila, nā pine PCB a me ka solder.

ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka nalu i ka hana nui, akā loaʻa iā ia kāna ʻano ponoʻī o nā hemahema, ʻo ia hoʻi:

1. kiʻekiʻe loa ka ʻai ʻana o ka solder

2. ʻai nui ia i ka flux

3. Hoʻohana nui ʻia ka mana o ka soldering wave

4. He kiʻekiʻe kona hoʻohana nitrogen

5. Pono e hana hou ʻia ke kuʻi ʻana o ka nalu ma hope o ke kuʻi ʻana o ka nalu

6. Pono nō hoʻi e hoʻomaʻemaʻe i ka pā nalu a me nā ʻāpana wili

7. Ma kahi huaʻōlelo, he kiʻekiʻe loa ke kumukūʻai o ka soldering nalu, a ua manaʻo ʻia ke kumukūʻai hana e aneane ʻelima mau manawa o ka welding koho.

Kuʻi koho

ʻO ke kuʻi koho koho he ʻano o ka nalu nalu, i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i nā lako hana SMT i hui pū ʻia me nā ʻāpana o loko.Hiki ke hoʻohua ʻia nā huahana liʻiliʻi a māmā hoʻi i ka wili nalu koho.

Loaʻa i ke kaʻina hana wiliwili koho:

Hoʻohana i ka flux ma luna o nā ʻāpana e welded / kaapuni papa preheating / solder nozzle no ka wiliwili ʻana i nā ʻāpana kikoʻī.

Nā pōmaikaʻi o ka welding koho:

1. Hoʻohana ʻia ka Flux ma ka ʻāina, no laila ʻaʻohe pono e pale i kekahi mau mea

2. ʻAʻole koi ʻia ka flux

3. Hiki iā ʻoe ke hoʻonohonoho i nā ʻāpana like ʻole no kēlā me kēia ʻāpana

4. ʻAʻole pono e hoʻohana i nā pā kūʻai hawewe aperture pipiʻi

5. Hiki ke hoʻohana ʻia no nā papa kaapuni ʻaʻole hiki ke hoʻoheheʻe ʻia

6. ʻO ka holoʻokoʻa, ʻo kona pono kūpono i nā mea kūʻai aku he haʻahaʻa haʻahaʻa

No laila, pehea e koho ai i kahi ʻano hana kaʻina hana PCB kūpono e pono e loiloi ʻia e nā mea kūʻai aku e like me nā ʻano o nā huahana.
