Yiniumshini wokukhetha nokubeka?
Umshini wokukhetha nendawo uyisihluthulelo nesiyinkimbinkimbi ekukhiqizeni i-SMT, esetshenziselwa ukunamathisela izingxenye ngesivinini esikhulu nokunemba okuphezulu.Manje umshini wokukhetha nendawo usuthuthukile ukusuka emshinini we-SMT womshini wejubane eliphansi ukuya ku-high speed optical centeringUmshini we-SMT, kanye nemisebenzi eminingi, ukuthuthukiswa kokuxhumeka okuguquguqukayo.Emigqeni yokukhiqiza ye-SMT, ifakwe umshini okhiphayo noma iphrinta yokunamathisela ye-solder ukuze ibeke ngokunembile izinto zokukhweza ngaphezulu kuphedi ye-PCB ngokuhambisa ikhanda lokukhweza.I-Colloquially, ingumshini wokunamathisela izingxenye ze-electronic pin chip ebhodini lesekethe.
Khetha bese ubeka umgomo wokusebenza komshini
Umshini wokukhetha nendawo ozenzakalelayo ulawulwa ikhompuyutha futhi uyisisetshenziswa esizenzakalelayo esinembayo esiphezulu esihlanganisa i-optics, ugesi negesi.Yakhiwa ikakhulukazi i-rack, i-PCB yokudlulisela kanye nenhlangano ethwala umthwalo, isistimu yokushayela, isistimu yokubeka indawo kanye ne-centering, ikhanda elikhuphukayo, i-feeder, isistimu yokuhlonza i-optical, inzwa kanye nohlelo lokulawula ikhompyutha.Ngokumunca, ukugudluza, ukubeka kanye nokubeka imisebenzi, izingxenye ze-SMD zingafakwa ngokushesha.
Ingabe i-pick futhi ibeke isolder yomshini?
Umshini wokukhetha nendawo awukwazi ukushisela.
I-NeDen inikeza umoya oshisayo wochwepheshereflow oven.Idlulisela amandla okushisa ngokusebenzisa ukunyakaza kwe-laminar komoya oshisayo.I-heater kanye nefeni kusetshenziselwa ukwenza umoya osesithandweni uhlale uphakama futhi ujikeleze.Ama-welds ashiswa ngegesi eshisayo esithandweni, ukuze abone ukushisela.Isithando somlilo se-oven reflow esishisayo sinezici zokushisa okufanayo nokushisa okuzinzile.Akulula ukulawula umehluko wezinga lokushisa phakathi kwe-PCB engaphezulu nephansi kanye nezinga lokushisa elihambisana nobude besithando somlilo, ngakho-ke ngokuvamile alisetshenziswa iyodwa.Kusukela ngeminyaka yawo-1990, ngokunwetshwa kwesicelo se-SMT kanye nokwenza kancane kancane kwezingxenye, abakhiqizi bokuthuthukiswa kwemishini ukuze bathuthukise ukusatshalaliswa kwe-heater, ukujikeleza kokugeleza komoya, kanye nebanga lokushisa elikhuphuka liye ku-8, 10, ukuze kuqhutshekwe nokulawula okunembayo. of esithandweni lokushisa ukusatshalaliswa kwengxenye ngayinye kulula ukulawulwa ekahle lokushisa ijika.Isithando somlilo esigcwele esishisayo esiphoqelelwe ukuba sigeleze kabusha somlilo sesiphenduke umshini wokushisela we-SMT ojwayelekile ngemva kokuthuthukiswa okuqhubekayo nokuphelela.
