Inqubo yokukhiqiza PCBA, ngenxa yezici eziningana kuzoholela isenzeko ingxenye drop, ke abantu abaningi ngokushesha bacabange ukuthi kungase kube ngenxa PCBA Welding amandla akwanele ukubangela.Ukwehla kwengxenye namandla okushisela kunobudlelwano obuqine kakhulu, kodwa ezinye izizathu eziningi zizobangela ukuthi izingxenye ziwe.
Amazinga wamandla e-solder eyingxenye
| Izingxenye Ze-elekthronikhi | Amazinga (≥) | |
| I-CHIP | 0402 | 0.65kgf |
| 0603 | 1.2kgf | |
| 0805 | 1.5kgf | |
| 1206 | 2.0kgf | |
| I-Diode | 2.0kgf | |
| Umsindo | 2.5kgf | |
| IC | 4.0kgf | |
Uma i-thrust yangaphandle idlula leli zinga, ingxenye izowa, engaxazululwa ngokushintsha i-solder paste, kodwa i-thrust ayinkulu kangako futhi ingaveza ukuvela kokuwa kwengxenye.
Ezinye izici ezidala ukuthi izakhi ziwe.
1. isici somumo wephedi, amandla ephedi ayindilinga kunamandla ephedi angunxande ukuba abe mpofu.
2. ingxenye ye-electrode coating ayilungile.
3. Ukumuncwa komswakama we-PCB kukhiqize i-delamination, akukho kubhaka.
4. Izinkinga zephedi le-PCB, nomklamo wephedi we-PCB, ohlobene nokukhiqiza.
Isifinyezo
Amandla wokushisela we-PCBA akusona isizathu esiyinhloko sokuthi izingxenye ziwe, izizathu ziningi.
