ʻAʻohe gula, ʻaʻohe mea kūpono", pēlā pū ka papa PCB.I ka PCB welding, ma muli o nā kumu like ʻole, ʻike pinepine ʻia nā hemahema, e like me ka welding virtual, overheating, bridging a pēlā aku.ʻO kēia ʻatikala, wehewehe mākou i nā kikoʻī i nā hiʻohiʻona hiʻohiʻona, nā pōʻino a me ke kumu o ka nānā ʻana o 16 mau hemahema PCB maʻamau.
01
wiliwili
Nā hiʻohiʻona hiʻohiʻona: Aia kahi palena ʻeleʻele maopopo ma waena o ka mea kūʻai aku a me ke alakaʻi o ka mea a i ʻole me ka pahu keleawe, a ua hoʻihoʻi ʻia ka solder i ka palena.
Poino: ʻAʻole hana pono.
Ka Ike Kumu:
ʻAʻole hoʻomaʻemaʻe ʻia nā alakaʻi o nā ʻāpana, tinned a oxidized.
ʻAʻole maʻemaʻe ka papa i paʻi ʻia, a maikaʻi ʻole ka maikaʻi o ka flux i hoʻoheheʻe ʻia.
02
ʻO ka hōʻiliʻili solder
Nā hiʻohiʻona hiʻohiʻona: ʻO ke ʻano o ka hui solder he wehe, keʻokeʻo a palupalu.
ʻO ka pilikia: ʻAʻole lawa ka ikaika mechanical, hiki ke hoʻopunipuni hewa.
Ka Ike Kumu:
ʻAʻole maikaʻi ka maikaʻi solder.
ʻAʻole lawa ka mahana kūʻai.
Ke hoʻopaʻa ʻole ʻia ka solder, lilo ke alakaʻi o ka ʻāpana.
03
Nui loa ka solder
Nā hiʻohiʻona hiʻohiʻona: He convex ka ʻili solder.
ʻO ka pōʻino: Hoʻopalapala ʻōpala, a loaʻa paha nā hemahema.
ʻIke kumu: ua lohi loa ka wehe ʻana o ka solder.
04
Liʻiliʻi solder
Nā hiʻohiʻona hiʻohiʻona: ʻO ka wahi kūʻai ma lalo o 80% o ka pad, a ʻaʻole i hana ka solder i kahi hoʻololi maʻalahi.
Pilikia: lawa ʻole ka ikaika mechanical.
Ka Ike Kumu:
ʻAʻole maikaʻi ka wai solder a i ʻole ua hoʻihoʻi koke ʻia ka solder.
ʻAʻole lawa ka lele.
He pōkole loa ka manawa wili.
05
ʻO ke kuʻi ʻana o Rosin
Nā hiʻohiʻona hiʻohiʻona: Loaʻa ka rosin slag i ka weld.
Hazard: ʻAʻole lawa ka ikaika, hoʻomau maikaʻi ʻole, a hiki ke hoʻololi ʻia a hoʻopau ʻia.
Ka Ike Kumu:
Nui loa nā welders a i ʻole i hāʻule.
ʻAʻole lawa ka manawa wili a lawa ʻole ka wela.
ʻAʻole wehe ʻia ke kiʻi ʻoniʻoni o ka ʻili.
06
wela loa
ʻO nā hiʻohiʻona hiʻohiʻona: nā hui solder keʻokeʻo, ʻaʻohe luster metala, ʻili ʻeleʻele.
Hazard: He maʻalahi ka ʻili a hoʻemi ʻia ka ikaika.
No ke kumu: nui loa ka mana o ka hao hao, a lōʻihi ka manawa hoʻomehana.
07
Kuʻi anu
Nā hiʻohiʻona hiʻohiʻona: lilo ka ʻili i nā ʻāpana like me ka tofu, a i kekahi manawa he māwae paha.
Poino: Haʻahaʻa ikaika a maikaʻi ʻole ka conductivity.
ʻIke kumu: ʻo ka solder jitters ma mua o ka paʻa ʻana.
08
Hoʻokomo maikaʻi ʻole
Nā hiʻohiʻona hiʻohiʻona: ʻO ka pilina ma waena o ka solder a me ka weldment he nui loa a ʻaʻole maʻalahi.
Hazard: Haʻahaʻa ka ikaika, ʻaʻole loaʻa a i ʻole a i ʻole i ka manawa a i ʻole.
Ka Ike Kumu:
ʻAʻole hoʻomaʻemaʻe ʻia ka weldment.
ʻAʻole lawa ka flux a maikaʻi ʻole paha.
ʻAʻole lawa ka wela o ka weldment.
09
Asymmetry
Nā hiʻohiʻona hiʻohiʻona: ʻaʻole kahe ka solder ma luna o ka pad.
Poino: lawa ole ka ikaika.
Ka Ike Kumu:
ʻAʻole maikaʻi ka wai o ka solder.
ʻAʻole lawa ka flux a maikaʻi ʻole paha.
ʻAʻole lawa ka wela.
10
ʻoluʻolu
Nā hiʻohiʻona hiʻohiʻona: Hiki ke hoʻoneʻe ʻia ke uea a i ʻole ke alakaʻi.
Puka: ʻAʻohe a i ʻole ka lawe ʻana.
Ka Ike Kumu:
Ke neʻe nei ke kēpau ma mua o ka hoʻopaʻa ʻia ʻana o ka solder a lilo i mea ʻole.
ʻAʻole hana maikaʻi ʻia ke kēpau (ʻilihune a pulu ʻole paha).
11
Hoʻokala
Nā hiʻohiʻona hiʻohiʻona: ʻoi.
ʻO ka pōʻino: He ʻano maikaʻi ʻole, maʻalahi ke hoʻopili ʻana.
Ka Ike Kumu:
ʻAʻole liʻiliʻi ka flux a lōʻihi loa ka manawa hoʻomehana.
He kihi hoʻokuʻu kūpono ʻole o ka hao hao.
12
huikau
Nā hiʻohiʻona hiʻohiʻona: pili nā uea pili.
Puka: Kaapuni pōkole uila.
Ka Ike Kumu:
Nui loa ka solder.
He kihi hoʻokuʻu kūpono ʻole o ka hao hao.
13
Pinhole
Nā hiʻohiʻona hiʻohiʻona: ʻike ʻia ka nānā ʻana a i ʻole nā mana haʻahaʻa haʻahaʻa e ʻike i nā lua.
Hazard: ʻAʻole lawa ka ikaika a me ka maʻalahi o ka ʻino ʻana o nā hui solder.
ʻIke kumu: ʻoi aku ka nui o ka ʻokoʻa ma waena o ke poʻo a me ka lua pad.
14
ʻōhū
Nā hiʻohiʻona hiʻohiʻona: aia kahi puʻupuʻu solder hanu ahi ma ke kumu o ke alakaʻi, a hūnā ʻia kahi lua i loko.
Hazard: ʻO ka lawe ʻana i ka manawa, akā maʻalahi ka hana ʻino ʻana no ka manawa lōʻihi.
Ka Ike Kumu:
Aia kahi ʻāpana nui ma waena o ke poʻo a me ka lua pad.
ʻAʻohe hoʻokomo kepau.
He lōʻihi ka manawa wili o ka pā ʻaoʻao ʻelua e hoʻopili ana i ka puka ma, a hoʻonui ka ea i loko o ka lua.
15
Hoʻopili ʻia ʻo Copper foil
Nā hiʻohiʻona hiʻohiʻona: Ua ʻili ʻia ka pahu keleawe mai ka papa i paʻi ʻia.
Poino: Ua poino ka papa i paiia.
ʻIke kumu: lōʻihi loa ka manawa wiliwili a kiʻekiʻe loa ka mahana.
16
Peel off
Nā hiʻohiʻona hiʻohiʻona: ʻili nā hui solder mai ka pahu keleawe (ʻaʻole ka ʻili keleawe a me ka ʻili o ka papa i paʻi ʻia).
Popilikia: Kaapuni hamama.
ʻO ke kumu noʻonoʻo: ʻino ka hoʻoheheʻe ʻana i ka metala ma ka pā.
