ʻO ke kūlana maʻamau o ka bead tin ma ka papa PCBA

ʻO ka maʻamau e ʻae ʻia no ka nui o ka bead tin ma ka ʻili papa PCBA.

1. ʻAʻole ʻoi aku ka nui o ke anawaena o ke kinipōpō i ka 0.13mm.

2. ʻAʻole ʻoi aku ma mua o 5 (ʻaoʻao hoʻokahi) ka helu o nā pahu tin me ke anawaena o 0.05mm-0.13mm i loko o ka laulā o 600mm.

3. ʻAʻole koi ʻia ka helu o nā pahu tin me ke anawaena o lalo o 0.05mm.

4. Pono e wahī ʻia nā pahu pahu a pau e ka flux a ʻaʻole hiki ke hoʻoneʻe ʻia (ʻo ke kahe i hoʻopaʻa ʻia i ʻoi aku ma mua o 1/2 o ke kiʻekiʻe o nā pahu tin ka ʻōwili ʻia).

5. ʻAʻole i hoʻemi nā ʻeke pīni i ka ʻae uila o nā mea hoʻokele pūnaewele ʻokoʻa ma lalo o 0.13mm.

'Ōlelo Aʻo: Koe wale no nā wahi mana kūikawā.

ʻO nā pae hoʻopaʻapaʻa hōʻole no nā pahu tin:

ʻO ka hoʻokō ʻole ʻana i nā koina e ʻae ʻia e ʻae ʻia.

ʻŌlelo:

1. Wahi hoʻomalu kūikawā: ʻaʻole ʻae ʻia nā pahu i ʻike ʻia ma lalo o kahi microscope 20x i loko o 1mm a puni ka pad capacitor ma ka hope manamana gula o ka laina hōʻailona ʻokoʻa.
2. He ʻōlelo aʻo ʻia nā pahu tin no ke kaʻina hana.No laila, pono e hoʻomaikaʻi mau nā mea hana chip SMT i ke kaʻina hana e hōʻemi i ka hiki ʻana o ka pahu tin.
3. ʻO ka maʻamau no ka nānā ʻana i ka PCBA kekahi o nā kūlana maʻamau no ka ʻae ʻana i nā huahana uila.E like me nā huahana like ʻole a me nā koi o ka mea kūʻai aku, ʻokoʻa nā koi ʻae ʻia no nā pahu tin.ʻO ka maʻamau, ua hoʻoholo ʻia ka maʻamau ma muli o ke kūlana aupuni a hui pū me nā koi o nā mea kūʻai aku.

ʻO PCBFuture kahi mea hana PCB a me ka mea hana PCB hui e hoʻolako me ka ʻoihana PCB ʻoihana, ke kūʻai ʻana i nā mea, a me ka hui PCB wikiwiki i nā lawelawe hoʻokahi.
