Ma ke kaʻina hana oNā papa kaapuni hui PCB, ʻaʻole hiki ke ʻike ʻia nā hemahema wili a me nā hemahema ke ʻano.ʻO kēia mau mea e hoʻopilikia iki i ka papa kaapuni.I kēia lā, hoʻopuka kēia ʻatikala i nā kikoʻī i nā hemahema wili maʻamau, nā hiʻohiʻona hiʻohiʻona, nā pōʻino a me nā kumu o ka PCBA.E nānā kākou E nānā iā ia!
Pseudo Soldering
Nā hiʻohiʻona hiʻohiʻona:aia ka palena ʻeleʻele maopopo ma waena o ka mea kūʻai aku a me ke keʻokeʻo o nā ʻāpana a i ʻole ke keleawe keleawe, a ua pohō ka mea kūʻai aku i ka palena.
Pilikia:hiki ʻole ke hana maʻamau.
ʻIkepili kumu:
1. ʻAʻole hoʻomaʻemaʻe ʻia nā alakaʻi ʻāpana, uhi ʻia a i ʻole oxidized.
2. ʻAʻole i hoʻomaʻemaʻe maikaʻi ʻia ka papa i paʻi ʻia, a ʻaʻole maikaʻi ka maikaʻi o ka flux sprayed.
ʻO ka hōʻiliʻili solder
Nā hiʻohiʻona hiʻohiʻona:ʻO ke ʻano o ka hui solder he ʻoluʻolu, keʻokeʻo a ʻeleʻele.
Ka Ike Kumu:
1. ʻAʻole maikaʻi ka maikaʻi solder.
2.ʻAʻole lawa ka mahana soldering.
3. I ka wā i hoʻopaʻa ʻole ʻia ai ka solder, wehe nā alakaʻi ʻāpana.
Nui loa ka solder
Nā hiʻohiʻona hiʻohiʻona:He convex ka ʻili solder.
Nā pōʻino:Hoʻopili ʻia nā ʻōpala a loaʻa paha nā hemahema.
ʻIkepili kumu:Ua lohi loa ka hoʻokuʻu ʻana i ka solder.
Liʻiliʻi solder
Nā hiʻohiʻona hiʻohiʻona:ʻOi aku ka liʻiliʻi o ka wīwī ma lalo o 80% o ka pad, a ʻaʻole i hana ka solder i kahi hoʻololi maʻalahi.
Pilikia:ʻAʻole lawa ka ikaika mechanical.
Ka Ike Kumu:
1.Poor solder kahe a i'ole ka ha'alele mua 'ana o ka solder.
2. Insufficient flux.
3.Welding manawa pōkole loa.
Kuʻi ʻo Rosin
Nā hiʻohiʻona hiʻohiʻona:Loaʻa ka ʻōpala rosin i ka weld.
Nā pōʻino:ʻAʻole lawa ka ikaika, maikaʻi ʻole ka hoʻokele ʻana, a hiki ke hele a i waho.
Ka Ike Kumu:
1. He nui nā mīkini wiliwili a i ʻole i hāʻule.
2.ʻAʻole lawa ka manawa wili a lawaʻole ka hoʻomehana.
3.ʻAʻole weheʻia ke kiʻi oxide ma kaʻili.
Ka wela nui
Nā hiʻohiʻona hiʻohiʻona:nā hui kuʻi keʻokeʻo, ʻaʻohe ʻulaʻula metala, ʻili ʻeleʻele.
Pilikia:He maʻalahi ka ʻili a hoʻemi ʻia ka ikaika.
ʻIkepili kumu:
Nui loa ka mana o ka hao hao a lōʻihi ka manawa hoʻomehana.
Kuʻi anu
Nā hiʻohiʻona hiʻohiʻona:ʻO ka ʻili he mau ʻāpana e like me ka bean curd, a i kekahi manawa he māwae paha.
Pilikia:ikaika haʻahaʻa, haʻahaʻa uila conductivity.
ʻIkepili kumu:Aia ka jitter ma mua o ka paʻa ʻana o ka solder.
Hoʻokomo maikaʻi ʻole
Nā hiʻohiʻona hiʻohiʻona:ʻO ka pilina ma waena o ka solder a me ka weldment he nui loa a ʻaʻole maʻalahi.
Pilikia:ka haʻahaʻa haʻahaʻa, ʻaʻohe pili a i ʻole pili ʻana.
Ka Ike Kumu:
1. ʻAʻole maʻemaʻe ka weldment.
2. ʻAʻole lawa a maikaʻi ʻole ka maikaʻi.
3.ʻAʻole i wela pono nā Weldments.
Asymmetrical
Nā hiʻohiʻona hiʻohiʻona:ʻAʻole kahe ka solder i ka pad.
Pilikia:ʻAʻole lawa ka ikaika.
Ka Ike Kumu:
ʻAʻole maikaʻi ʻo 1.Solder fluidity.
2. ʻAʻole lawa a maikaʻi ʻole ka maikaʻi.
3.ʻAʻole lawa ka wela.
wehe
Nā hiʻohiʻona hiʻohiʻona:Hiki ke hoʻoneʻe ʻia nā uea a i ʻole nā mea alakaʻi.
Pilikia:ʻilihune a ʻaʻohe alakaʻi.
Ka Ike Kumu:
1. Ke neʻe nei ke alakaʻi ma mua o ka paʻa ʻana o ka solder, e hoʻoheheʻe ʻia.
2. ʻAʻole mākaukau maikaʻi nā alakaʻi (ʻilihune a ʻaʻole i pulu).
ʻOi ʻana
Nā hiʻohiʻona hiʻohiʻona:ʻO ke ʻano o kahi piko.
Pilikia:maikaʻi ʻole ke ʻano, maʻalahi ke kumu o ka hoʻopili ʻana.
Ka Ike Kumu:
1. ʻAʻole liʻiliʻi ka flux a lōʻihi loa ka manawa hoʻomehana.
2. ʻAʻole kūpono ke kihi o ka hao hao e hoʻihoʻi.
Hoʻopili ʻana
Nā hiʻohiʻona hiʻohiʻona:Hoʻopili ʻia nā uea pili.
Pilikia:Kaapuni pōkole uila.
Ka Ike Kumu:
1. Nui loa solder.
2. ʻAʻole kūpono ke kihi o ka hao hao e hoʻihoʻi.
ʻāʻī
Nā hiʻohiʻona hiʻohiʻona:Aia nā puka i ʻike ʻia e ka nānā ʻana a i ʻole ka hoʻonui haʻahaʻa.
Pilikia:ʻAʻole lawa ka ikaika, maʻalahi nā ami solder e ʻino.
ʻIkepili kumu:Nui loa ka ʻokoʻa ma waena o ke poʻo a me ka lua pad.
ʻōhū
Nā hiʻohiʻona hiʻohiʻona:ʻO ke kumu o ke kēpau he puʻupuʻu puhi ahi, a he lua i loko.
Pilikia:ʻO ka conduction manawa, akā he maʻalahi ke kumu o ka hana maikaʻi ʻole no ka manawa lōʻihi.
Ka Ike Kumu:
1. ʻO ke āpau ma waena o ke alakaʻi a me ka lua pad he nui.
2.Poor pulu kepau.
3. Ua lōʻihi ka manawa kuʻi o ka papa ʻaoʻao ʻelua ma o nā lua, a hoʻonui ka ea i loko o nā lua.
ʻO ka makaihoʻokiʻekiʻe ʻia i kēlā me kēia pahu
Nā hiʻohiʻona hiʻohiʻona:Hoʻopili ʻia ka pahu keleawe mai ka papa i paʻi ʻia.
Pilikia:Ua poino ka papa i paiia.
ʻIkepili kumu:He lōʻihi loa ka manawa wiliwili a kiʻekiʻe loa ka mahana.
Peel
Nā hiʻohiʻona hiʻohiʻona:Hoʻopili ʻia nā hui solder mai ka pahu keleawe (ʻaʻole ka pahu keleawe a me ka papa i paʻi ʻia).
Pilikia:Kaapuni hamama.
ʻIkepili kumu:ʻAʻole i hoʻopaʻa ʻia ka metala ma ka pā.
Ma hope o ka nānā 'ana i nā kumu oHoʻohui ʻia ʻo PCBnā hemahema, hilinaʻi mākou i ka hāʻawi ʻana iā ʻoe i ka hui maikaʻi loahuli-ki PCB lawelawe hui, ka maikaʻi, ke kumu kūʻai a me ka manawa hāʻawi i kāu ʻāpana liʻiliʻi liʻiliʻi PCB hui kauoha a me ka Mid batch Volume PCB kauoha hui.
Inā ʻoe e ʻimi nei i kahi mea hana hui PCB kūpono, e ʻoluʻolu e hoʻouna i kāu faila BOM a me nā faila PCB i sales@pcbfuture.com.He hūnā loa kāu mau faila a pau.E hoʻouna mākou iā ʻoe i kahi ʻōlelo pololei me ka manawa alakaʻi i nā hola 48.
