BGA rework stationinyanzvi yemidziyo inoshandiswa kugadzirisa BGA zvikamu, izvo zvinowanzo shandiswa muindasitiri yeSMT.Tevere, isu tichasuma musimboti wekutanga weBGA rework station uye tiongorore zvakakosha zvekuvandudza mwero wekugadzirisa weBGA.
BGA rework station inogona kukamurwa kuita optical counterpoint kugadzirisa tafura uye isiri-optical counterpoint kugadzirisa tafura.Optical counterpoint inoreva kurongeka kwe optics panguva yewelding, iyo inogona kuve nechokwadi chekurongeka kwewelding alignment uye kuvandudza mwero wekubudirira kwewelding.Non-optical counterpoint, iyo inoitwa nemaziso, haina kunyatsojeka kana welding.
Parizvino, nzira huru dzekudziya dzeBGA rework station dzinosanganisira yakazara infrared, yakazara inopisa mweya uye maviri emhepo inopisa uye imwe infrared.Nzira dzakasiyana dzekudziya dzine zvakanakira uye nekuipa kwakasiyana.Iyo yakajairwa yekudziya nzira yeBGA rework station muChina inowanzo kupisa mhepo kumusoro nepasi uye infrared preheating pazasi, inonzi matatu-tembiricha zone.Iyo yepamusoro uye yakaderera misoro yekudziya inopisa nekupisa waya uye mhepo inopisa inotengeswa kunze nekuyerera kwemhepo.Pazasi preheating inogona kukamurwa kuita yakasviba yekunze yekudziya chubhu, infrared heat plate uye infrared light wave heat plate.
1. Kupisa nekudzika nekupenya
Kuburikidza nekudziya waya yekudziya, mhepo inopisa ichaendeswa kune zvikamu zveBGA kuburikidza nemhepo yemhepo, kuti iwane chinangwa chekupisa BGA zvikamu, uye kuburikidza nepamusoro nepamusoro pemhepo inopisa inopisa, inogona kudzivirira bhodhi redunhu risina kuenzana kupisa deformation.
2. Pazasi infrared kudziyisa
Infrared heat inonyanya kuita preheating basa, kubvisa hunyoro mubhodhi redunhu uye BGA, uye inogona zvakare kunyatso kudzikisa mutsauko wetembiricha pakati penzvimbo yekudziya uye yakatenderedza, ichideredza mukana wekutenderera bhodhi deformation.
3. Kutsigira uye kugadzirisa kweBGA rework station
Ichi chikamu chinonyanya kutsigira uye kugadzirisa bhodhi redunhu uye inoita basa rinokosha mukudzivirira deformation yebhodhi.
4. Kudzora tembiricha
Pakuputsa uye welding BGA, pane chakakosha chinodiwa chekushisa.Kana tembiricha yakawandisa, zviri nyore kupisa zvikamu zveBGA.Naizvozvo, tafura yekugadzirisa inowanzodzorwa pasina chiridzwa, asi inotora PLC kutonga uye yakazara komputa kutonga, iyo inogona kudzora tembiricha munguva chaiyo.
Paunenge uchigadzirisa BGA nerework station, inonyanya kudzora kupisa kwekupisa uye kudzivirira deformation yedare redunhu.Chete nekuita zvikamu zviviri izvi zvakanaka zvinogona kubudirira chiyero chekugadzirisa BGA kunyatsovandudzwa.
Zhejiang NeoDen Technology Co., Ltd yave kugadzira uye kutumira kunze kwakasiyana siyanatora nekuisa michinakubvira 2010. Tichitora mukana wedu pachedu akapfuma ane ruzivo R&D, akadzidziswa kugadzirwa zvakanaka, NeoDen inohwina mukurumbira mukuru kubva pasi rese vatengi.
