6. Ukushisa ngokweqile
Izici zokubukeka: i-solder emhlophe ehlangene, ayikho i-metallic luster, indawo eqinile.
Ukulimala: i-pad kulula ukuyikhipha futhi amandla ayancipha.
Isizathu: amandla ensimbi ye-solder makhulu kakhulu, futhi isikhathi sokushisa side kakhulu.
7. Ukushisela okubandayo
Izici zokubukeka: Ingaphezulu liyi-granular, futhi ngezinye izikhathi kungase kube nemifantu.
Ukulimala: Amandla aphansi kanye nokungahambi kahle kahle.
Isizathu: i-solder iyanyakaziswa ngaphambi kokuba iqine.
8. Ukungenwa kahle
Izici zokubukeka: i-interface phakathi kwe-solder ne-weldment inkulu kakhulu futhi ayibushelelezi.
Ukulimala: amandla aphansi, akukho ukufinyelela noma isikhathi sokuvula nokuvala.
Isizathu: i-weldment ayihlanzwa.I-Flux ayanele noma ayikhwalithi ephansi.I-weldment ayishisi ngokugcwele.
9. Asymmetric
Izici zokubukeka: i-solder ayigelezi phezu kwephedi.
Ukulimala: Amandla anganele.
Isizathu: i-solder ayinamanzi amancane.Ukuguquguquka okunganele noma ikhwalithi ephansi.Ukushisa okunganele.
10. Okuxekethile
Izici zokubukeka: Intambo noma ingxenye yomthofu ingasuswa.
Ukulimala: kubi noma okungaqhubeki.
Isizathu: ngaphambi kokuthi i-solder iqine, intambo eholayo iyahamba ukuze ibangele izikhala.Umthofu awucutshungulwanga kahle.
11. I-Cusp
Izici zokubukeka: bukhali.
Ukulimala: ukubukeka kabi, kulula ukubangela ukuvala ibhuloho
Isizathu: ukugeleza okuncane kakhulu nesikhathi sokushisa eside kakhulu.I-angle yokushiya ye-soldering iron ayilungile.
12. Ukuhlanganisa
Izici zokubukeka: izintambo eziseduze zixhunyiwe.
Ukulimala: Isifunda esifushane sikagesi.
Isizathu: solder kakhulu.I-engeli engalungile yokuhoxiswa kwe-solder iron.
13. Iphinifa
Izici zokubukeka: ukuhlola okubonakalayo noma izikhulisamandla ezinamandla aphansi zingabona izimbobo.
Ukulimala: amandla anganele, i-solder joint kulula ukugqwala.
Isizathu: igebe phakathi komthofu nembobo yephedi likhulu kakhulu.
14. Igwebu
Izici zokubukeka: kukhona iqhubu le-solder eliphefumula umlilo empandeni yomthofu, futhi umgodi ufihliwe ngaphakathi.
Ukulimala: ukuqhutshwa kwesikhashana, kodwa kulula ukubangela ukungahambi kahle isikhathi eside.
Isizathu: igebe phakathi kokuhola kanye nomgodi we-welding disc likhulu.Ukungena kahle komthofu.Isikhathi sokushisela sokuxhunywa kwezinhlangothi ezimbili emigodini side, futhi umoya osezimbobeni uyakhula.
15. Ucwecwe lwethusi olusontekile
Izici zokubukeka: i-foil yethusi ihlutshiwe ebhodini eliphrintiwe.
Ingozi: I-PCB yonakele.
Isizathu: isikhathi sokushisela side kakhulu futhi izinga lokushisa liphezulu kakhulu.
16. Khubula
Izici zokubukeka: amalunga e-solder aphuma ku-foil yethusi (hhayi i-copper foil ne-PCB).
Ukulimala: Isekhethi evulekile.
Isizathu: ukufakwa kwensimbi embi kuphedi.
I-PCBFuture ihlinzeka ngazo zonke izinsiza zokuhlanganisa ze-PCB ezibandakanya konke, okuhlanganisa ukukhiqizwa kwe-PCB, ukuthola ingxenye kanye nokuhlanganiswa kwe-PCB.EyethuIsevisi ye-Turnkey PCBiqeda isidingo sakho sokuphatha abahlinzeki abaningi ngezikhathi eziningi, okuholela ekwengezeni ukusebenza kahle kanye nokusebenza kahle kwezindleko.Njengenkampani eqhutshwa ikhwalithi, sisabela ngokugcwele ezidingweni zamakhasimende, futhi singahlinzeka ngezinsizakalo ezifika ngesikhathi kanye nezomuntu siqu izinkampani ezinkulu ezingeke zilingise.Singakusiza ukuthi ugweme ukonakala kwe-PCB ekuthengisweni kwemikhiqizo yakho.
