Ma hopeSMT reflow wiliwilie ʻike mākou i kekahi mau mea kīnā ʻole, e hoʻopili pololei kēia mau hemahema SMT hoʻoili i ka maikaʻi o ka huahana.ʻO kēia mau mea kīnā ʻole he mea hoʻohana SMT ma ka hoʻoponopono ʻana i nā hemahema o ka hoʻoponopono ʻana i ka patch, i mea e hāʻawi ai i ka pae ʻoihana no ka hoʻomaikaʻi ʻana i ka hana a me ka hana ʻana o ka inoa maikaʻi ʻole.I ka hana ʻana i ka patch maoli no kēia mau ʻano hemahema i ʻike ʻia, pono e hana hou ʻia a hoʻoponopono hou ʻia paha.No laila pehea mākou e hoʻomaopopo ai i ka hoʻoholo ʻana i ke ʻano ʻino?
Ma lalo no ʻoe e hoʻokaʻawale i kēia mau mea:
1. (even tin) SMT hana welding hiki i ke tin ua ikeia no hoi me ke alahaka tin, ma waena o nā mea welau, ma waena o pili solder ami o na mea, a me ka solder ami a pili uea, perforations, etc. ʻO ka solder i hoʻohui pū ʻia, ʻoihana hana SMT i kapa ʻia ʻo tin.
2. (Monument) pōhaku kupapaʻu, ʻike ʻia hoʻi ʻo Manhattan phenomenon, e pili ana i ka hope soldering ʻelua o nā ʻāpana chip, ma hope o ka hoʻokuʻu hou ʻana, ʻo kekahi o ka hope soldering mai ka ʻili papa o ka mea holoʻokoʻa he oblique a pololei.ʻO ka ʻoihana SMT i kapa ʻia ka monument.
3. (ʻaoʻao kū) chip ʻaoʻao ʻaoʻao a me ka PCB pad contact phenomenon.ka ʻoihana SMT i kapa ʻia ʻaoʻao kū.
4. (offset) nā ʻāpana i ke kūlana ākea e neʻe, e hopena i ka hopena solder a ʻaʻole i hoʻopili ʻia i ka pā PCB.
5. (anti-keʻokeʻo) ʻāpana o ka mea mua i ka PCB, ka ʻaoʻao lalo i luna hanana.
6. (Pina pahu) i ka reflow soldering, pili i ka apana o ka aoao aoao a i hoopuehuia i loko o ka solder ami hoohui liilii o ka solder.
7. (cold soldering) reflow incomplete phenomena, ka solder 'a'ole i hiki i kona melting point wela a welding wela 'aʻole lawa, no laila, ua solidified ma mua o ka pulu a me ka kahe ana,ʻaʻohe hoʻokumu o kekahi metala paʻa hao, i mea a pau. a i ʻole kekahi ʻāpana o ka mea kūʻai aku i loko o kahi kūlana kristal ʻole a kūkulu wale ʻia ma luna o ka ʻili o ka metala i kūʻai ʻia.
8. (core suction) solder mai ka pad ma ka pine e pi'i ai i ka pine a me ke kino chip, no ka lawa ole o ka solder a i ole ia ka mea hao wale ma na hui solder.
9. (Reverse) e pili ana i ka polarity o nā mea ma hope o ke kuʻi ʻana, ʻaʻole kūlike ka polarity o ke kuhikuhi o nā koi maoli o ke kuhikuhi.
10. (Bubble) solder i ka solidification o ke kinoea ma mua o ka 'ole e pakele i ka manawa, ke kukuluia'na o ka hollow hanana i loko o ka solder hui.
11. (pinhole) i loko o ka solder hui ili e hana i ka nila-like puka.
12. (Fissure) nā hono solder ma muli o ke koʻikoʻi mechanical a i ʻole ke koʻikoʻi o loko ma muli o ke ʻano o nā ami solder naha.
13. (Tina tip) wiliwili ma ka puka o waho e like me ka nila a i ʻole ke kī.
14. (ʻoi aku ka tin) solder ma ka solder ʻoi aku ka nui ma mua o ka nui o ka koi, no laila he paʻakikī ke ʻike i ka outline o nā ʻāpana soldered a i ʻole solder e hana i kahi puʻu spherical.
15. (Wehe Solder) 'āpana pine / solder hope o nā mea a pau i waho a i ʻole mai ko lākou mau pā e pili ana, ʻaʻole ma muli o ke kūʻai ʻana.
16. (keʻokeʻo kiko) i loko o ka laminated substrate i loko o kekahi hanana, i loko o ka aniani puluniu i loko o ka longitudinal a me ka transverse kea a me resin kaʻawale.Hōʻike ʻia kēia ʻano ma ke ʻano he mau kiko keʻokeʻo ʻokoʻa a i ʻole ka ʻili o ka substrate ma lalo o ka "cross-shaped", pili pinepine me ka hoʻokumu ʻana o ke kaumaha ma muli o ka wela.
17. (Gy welding) ma muli o ke kiʻekiʻe welding wela, excessive flux evaporation a me ka hana hou kuʻihao, etc., ka ili o ka weld ua hina, ka solder kristal wehe, porous a me ka slag-like.
ʻO Zhejiang NeoDen Technology Co., LTD., i hoʻokumu ʻia i ka makahiki 2010, he mea hana loea i ka mīkini koho SMT a me kahi mīkini, reflow umu, mīkini paʻi stencil, laina hana SMT a me nā huahana SMT ʻē aʻe.Loaʻa iā mākou kā mākou hui R&D ponoʻī a me ka hale hana ponoʻī, e hoʻohana ana i kā mākou R&D ʻike waiwai ponoʻī, hoʻomaʻamaʻa maikaʻi ʻia, lanakila maikaʻi ʻia mai nā mea kūʻai aku o ka honua.
Aia mākou i kahi kūlana maikaʻi ʻaʻole wale e hāʻawi iā ʻoe i ka mīkini pnp kiʻekiʻe kiʻekiʻe, akā ʻo ka lawelawe maikaʻi loa ma hope o ke kūʻai aku.
E hāʻawi nā ʻenekini hoʻomaʻamaʻa maikaʻi iā ʻoe i ke kākoʻo ʻenehana.
Hiki i nā ʻenekini 10 ikaika ma hope o ke kūʻai aku ke pane aku i nā nīnau a me nā nīnau i loko o 8 mau hola.
Hiki ke hāʻawi ʻia nā hoʻonā ʻoihana i loko o 24 mau hola i ka lā hana a me nā lā hoʻomaha.
