Ubuchwepheshe beNtaba Engaphezulu (i-SMT): Ubuchwepheshe bokucubungula amabhodi e-PCB ayi-bare PCB futhi ubeke izingxenye ze-elekthronikhi ebhodini le-PCB. Lokhu kungubuchwepheshe obudumile kakhulu bokusebenza ngogesi kulezi zinto ezenziwa nge-elekthronikhi baya ngokuya bencane futhi bathambekele kancane kancane esikhundleni sobuchwepheshe be-dip plug-in. Womabili ubuchwepheshe bungasetshenziswa ebhodini elifanayo, nobuchwepheshe be-thru-hole obusetshenziselwe izakhi ezingalungele ukubekwa phezulu okufana nabaguquli abakhulu kanye nama-semiconductors amakhulu okushisa.
Ingxenye ye-SMT imvamisa incane kunokulinganiselwa kwayo oku-thru-hole ngoba inezinkulumo ezincane noma ziholele nhlobo. Kungahle kube nezikhonkwane ezimfushane noma ukuhola kwezitayela ezahlukahlukene, oxhumana nabo abasefulethini, i-matrix yamabhola we-soler (BGAS), noma ukunqamuka emzimbeni wengxenye.
Izici ezikhethekile:
> Umshini wejubane ophezulu we-Pick Pick & Indawo usethelwe konke okuncane, ama-Median kuya emhlanganweni omkhulu we-SMT (SMTA).
> Ukuhlolwa kwe-x-ray komhlangano osezingeni eliphakeme we-SMT (i-SMTA)
> Umugqa womhlangano ubeka ukunemba +/- 0.03 mm
> Phatha amaphaneli amakhulu kuze kube ngu-774 (l) x 710 (w) mm ngosayizi
> Phatha usayizi wezakhi ku-74 x 74, ukuphakama kuze kufike ku-38.1 mm ngosayizi
> Umshini we-PQF Pick & Place usinike ukuguquguquka okwengeziwe kwebhodi elincane lokugijima kanye ne-prototype board ukwakha.
> Wonke umhlangano we-PCB (PCBA) olandelwa yi-IPC 610 Class II ejwayelekile.
> I-Surface Mount Technology (SMT) Umshini Wokukhetha kanye Nezindawo Sinika amandla okusebenza nge-Surface Mount Conport Technology (SMT) iphakheji yengxenye encane kune-01 005 okuyi-1/4 usayizi wengxenye engu-1/4.
