7. Ukuwelda okubandayo
Iimpawu zembonakalo: Umphezulu we-granular, kwaye ngamanye amaxesha kunokubakho iintanda.
Ubungozi: Amandla aphantsi kunye nokungahambi kakuhle.
Isizathu: i-solder iyashukunyiswa ngaphambi kokuba iqine.
8. Ukungena kakubi
Iimpawu zembonakalo: ujongano phakathi kwe-solder kunye ne-weldment inkulu kakhulu kwaye ayigudi.
Ubungozi: Amandla aphantsi, akukho ukufikelela okanye ixesha lokuvula kunye nokucima.
Isizathu: i-weldment ayicocwanga.I-Flux ayonelanga okanye ikumgangatho ophantsi.I-weldment ayishushu ngokupheleleyo.
9. Asymmetric
Iimpawu zokubonakala: i-solder ayidluli phezu kwe-pad.
Ukwenzakala: Amandla angonelanga.
Isizathu: i-solder ayinamanzi amdaka.Ukuguquguquka okunganelanga okanye umgangatho ophantsi.Ukufudumeza okungonelanga.
10. Ekhululekile
Iimpawu zenkangeleko: Ucingo okanye icandelo lelothe lingashukunyiswa.
Ubungozi: Imbi okanye ayiqhutywanga.
Isizathu: phambi kokuba i-solder iqine, ucingo olukhokelayo luyahamba lubangele i-voids.Ilothe ayilungiswanga kakuhle.
11. Cusp
Iimpawu zembonakalo: zibukhali.
Ubungozi: inkangeleko embi, kulula ukwenza ibhulorho
Isizathu: i-flux encinci kunye nexesha elide lokufudumeza.I-angle yokushiya intsimbi ye-soldering ayifanelekanga.
