ʻO ke kaʻina hana PCBA, ma muli o ka nui o nā kumu e alakaʻi ai i ka hiki ʻana o ka hāʻule ʻana o ka mea, a laila e manaʻo koke nā poʻe he nui paha ma muli o ka ikaika kuʻihao PCBA ʻaʻole lawa ke kumu.ʻO ka hāʻule ʻana o ka ʻāpana a me ka ikaika welding he pilina ikaika loa, akā nui nā kumu ʻē aʻe e hāʻule ai nā ʻāpana.
Nā kūlana ikaika o ka hoʻoheheʻe ʻana i nā mea
| Nā Mea Elele | Nā kūlana (≥) | |
| CHIP | 0402 | 0.65kgf |
| 0603 | 1.2kgf | |
| 0805 | 1.5kgf | |
| 1206 | 2.0kgf | |
| Diode | 2.0kgf | |
| Audion | 2.5kgf | |
| IC | 4.0kgf | |
Ke ʻoi aku ka ʻoi o waho ma mua o kēia maʻamau, e hāʻule ka ʻāpana, hiki ke hoʻopau ʻia ma ke pani ʻana i ka paʻi solder, akā ʻaʻole nui ka nui o ka pahu hiki ke hoʻopuka i ka hāʻule ʻana o ka mea.
ʻO nā kumu ʻē aʻe e hāʻule ai nā ʻāpana.
1. ke kumu kumu o ka pad, poepoe pad ikaika ma mua o ka rectangular pad ikaika e ilihune.
2. ʻaʻole maikaʻi ka ʻāpana electrode coating.
3. PCB moisture absorption ua hana i ka delamination, aole bakena.
4. PCB pad pilikia, a me ka PCB pad manao, hana-pili.
Hōʻuluʻulu manaʻo
ʻAʻole ʻo ka ikaika wili PCBA ke kumu nui e hāʻule ai nā ʻāpana, ʻoi aku ke kumu.
