PCBA kugadzirwa muitiro, nokuda anoverengeka zvinhu kuchaita kuti kuitika chechikamu donhwe, ipapo vanhu vakawanda vachakurumidza kufunga kuti zvingava nokuda PCBA nomoto simba harina kukwana kukonzera.Kudonha kwechikamu uye kusimba kwewelding kune hukama hwakasimba kwazvo, asi zvimwe zvikonzero zvakawanda zvinozoita kuti zvikamu zviwire.
Component soldering simba mitemo
| Electronic Components | Zviyero (≥) | |
| CHIP | 0402 | 0.65kgf |
| 0603 | 1.2kgf | |
| 0805 | 1.5kgf | |
| 1206 | 2.0kgf | |
| Diode | 2.0kgf | |
| Sravana Sameeralu Serial 4th Audion | 2.5kgf | |
| IC | 4.0kgf | |
Kana iyo yekunze inosimudzira ichipfuura chiyero ichi, chikamu chinodonha, chinogona kugadziriswa nekutsiva solder paste, asi iyo yekusundidzira haina kukura zvakanyanya inogona zvakare kuburitsa kuitika kwekudonha kwechikamu.
Zvimwe zvikonzero zvinoita kuti zvikamu zvidonhe ndizvo.
1. Pedhi chimiro chinhu, denderedzwa padhi simba pane rectangular pedhi simba kuva murombo.
2. chikamu che electrode coating hachisi chakanaka.
3. PCB mwando absorption yakagadzira delamination, hapana kubika.
4. PCB pad matambudziko, uye PCB padhi dhizaini, kugadzirwa-ane chokuita.
Summary
PCBA welding simba haisi chikonzero chikuru chekuti zvikamu zvidonhe, zvikonzero zvakawanda.
