Mukuita kwePCB kugadzira, isu tagumburwa kukurudzirwa kuti tulize PCB setabhu -routing yekubata nemabhodhi edu edge.pano tichakupa yakadzama sumo yetab -routing process.
Chii chinonzi tab routing?
Tab routing inzira yakakurumbira yePCB panelisation inoshandisa ma tabo ane kana asina perforations.Kana iwe uri kupatsanura maPCB epaneru nemaoko, iwe unofanirwa kushandisa iyo perforated mhando.Kana iwe uchifunga kuti kutyora PCB kubva papaneru kunokonzeresa kushushikana kwakanyanya paPCB, zvine hungwaru kushandisa chinhu chakakosha chinodzivirira kukuvara kwebhodhi.
Kana bhodhi riine chimiro chisina kujairika, kana bhodhi richida mupendero wakajeka saka pani inoda kuve tabhu -kufambiswa.Fig 8 inoratidza kudhirowa kweiyo tab -routing pani, Fig 9 ndiyo foto yetabhu -routing panhi.Mune tab-routing panel kuitira kupaza bhodhi kubva papaneru mushure megungano, V mamaki kana "maburi ekuruma mbeva" anogona kushandiswa.Mouse bite holes mutsetse wemaburi unoshanda zvakafanana nemaburi ari pahurongwa hwezvitambi.Asi ramba uchifunga V zvibodzwa zvichapa mupendero wakajeka mushure mekunge mapuranga aputsika kubva pamapuranga, "mbeva inoruma maburi" haizopi kupenya kwakajeka.
Nei tichida kuisa mabhodhi se tad-routing?
Imwe yemabhenefiti e-tab-routing ndeyekuti iwe unogona kugadzira asiri-rectangular mabhodhi.Sezvineiwo, kukanganisa kwe-tab-routing ndeyekuti inoda yakawedzera bhodhi zvinhu, izvo zvinogona kuwedzera mutengo wako.Iyo zvakare inogona kuisa zvakanyanya kushushikana pabhodhi padhuze netabhu.Kudzivirira kushushikana kwebhodhi, dzivirira kuisa zvikamu zvePCB padhuze nematabo.Nepo pasina chiyero chakananga chekuisa zvikamu padhuze nematabo, kazhinji kutaura, 100 mils chinhambwe chakajairika.Pamusoro pezvo, ungangoda kuisa zvikamu zvinopfuura zana mils kune hombe kana kukora maPCB.
Unogona kubvisa maPCB mumapanera vasati vaungana kana mushure.Sezvo mapaneru ePCB achiita kuti zvive nyore kuunganidza, nzira yakajairika ndeyekubvisa maPCB mushure mekunge pani yaunganidzwa.Nekudaro, iwe unofanirwa kushandisa kumwe kungwarira paunenge uchibvisa maPCB kubva pamapanera mushure mekunge aunganidzwa.
Kana iwe usina yakakosha PCB yekubvisa chishandiso, unofanirwa kungwarira paunenge uchibvisa PCBS kubva pane pane.Usazvipeta!
Kana iwe waizobvisa PCB kubva papanera pasina hanya, kana kunyangwe zvikamu zviri padyo nematabo, unogona kusangana nekukuvara kwezvikamu.Mukuwedzera, solder joint dzimwe nguva kuputika, izvo zvinogona kukonzera matambudziko gare gare.Inosarudzwa kushandisa chishandiso chekucheka kubvisa maPCB kudzivirira kupeta bhodhi.
PHILIFAST yakazvipira mukugadzira PCB kwemakore mazhinji, uye kubata nePCB edges zvakanaka kwazvo.Kana paine dambudziko mumapurojekiti ako ePCB, ingoenda kune nyanzvi muPHILIFAST, vanokupa mazano ehunyanzvi.
