Inkqubo yokuvelisa PCBA, ngenxa yezinto ezininzi kuya kukhokelela kwisehlo ukuhla icandelo, ngoko abantu abaninzi baya kucinga ngoko nangoko ukuba ngenxa PCBA ukuwelda amandla akwanelanga ukuba kubangele.Ukwehla kwecandelo kunye namandla e-welding kunobudlelwane olomeleleyo, kodwa ezinye izizathu ezininzi ziya kubangela ukuba amacandelo awe.
Imigangatho yamandla e-soldering yecandelo
| Amacandelo ombane | Imigangatho (≥) | |
| I-CHIP | 0402 | 0.65kgf |
| 0603 | 1.2kgf | |
| 0805 | 1.5kgf | |
| 1206 | 2.0kgf | |
| Diode | 2.0kgf | |
| IAudiyon | 2.5kgf | |
| IC | 4.0kgf | |
Xa i-thrust yangaphandle idlula lo mgangatho, icandelo liya kuwa, elinokuthi lisonjululwe ngokutshintshela i-solder paste, kodwa i-thrust ayinkulu kangako inokuvelisa isenzeko sokuwa kwecandelo.
Ezinye izinto ezibangela ukuba amacandelo awe.
1. Umba wepad, amandla ephedi angqukuva ngaphezu kwamandla ephedi exande ukuba ahlupheke.
2. icandelo electrode ukutyabeka akulunganga.
3. I-PCB yokufunxa ukufuma ivelise i-delamination, akukho kubhaka.
4. iingxaki pad PCB, kunye noyilo PCB iphedi, ezinxulumene-mveliso.
Isishwankathelo
PCBA welding amandla ayisosizathu siphambili ukuba amacandelo awe, izizathu ngakumbi.
