Dab tsi yog Fiducial Cim
Fiducial cim lossis ntaus cim yog cim qauv cim Circuit Court. Cia li nws yog ib puag ncig solder daim npog qhib nrog puag ncig liab qab tooj liab nyob rau hauv qhov chaw. Liab qab tooj liab muaj qhov ntev dua li cov npog ntsej muag ntsuab. Saib duab 1.
Daim duab 1. Fiducial Mark
Txheeb xyuas thiab muab cov tshuab siv Fiducial cim raws li cov ntsiab lus tsis txaus siab ntawm PCB los tso qhov Chaw Thaj Tsam Mount Mount Cheebtsam (Cov Pob) ntawm PCB thaum sib sau ua ke ntawm Printed Circuit Board.
Dab tsi yog qhov loj me ntawm fiducial qhab nia?
Nws ua raws lub tshuab sib dhos. Qhov loj me ntawm 3.2mm solder daim npog qhov taub thiab 1.6mm txoj kab uas hla tooj liab los yog 2 hli cam daim npog qhov taub thiab 1mm txoj kab uas hla ntawm liab qab tooj liab tau zoo heev rau yuav luag txhua lub rooj sib dhos tshuab. Daim duab 2. qhia qhov ntev ntawm cov cim fiducial.

Coob npaum li cas thiab rau qhov twg tso lawv?
Yog tias koj muaj cov khoom SMD rau ntawm ob sab ntawm PCB koj yuav tsum tso nws rau ob sab saum toj thiab hauv qab ntawm koj qhov teeb tsa.
Tsis muaj kev cai nruj heev rau cov xov tooj fiducial. Nws yog qhov zoo yog tias koj tso ob lub fiducial cim rau ntawm cov ces kaum ntawm PCB ze ntawm lub kaum pob kaum. Yog tias koj muaj BGA, QFN, QFP pob nrog pob me me ntawm qhov tso, nws tau pab zoo heev los tso ib qho fiducial cim ze rau txhua tus ntawm cov pob / taw. Daim duab 3. qhia txog haujlwm ntawm fiducial cim ntawm lub rooj tsavxwm nrog ib QFN thiab ib QFP pob nrog lub suab me.
Daim duab 3. Txoj Haujlwm ntawm fiducial cim rau ntawm PCB
Nws tseem muaj txiaj ntsig thiab qee zaum tsim nyog tso plaub fiducial cim ze rau ntawm cov vaj huam sib luag fab. Peb pom zoo kom koj tso nws rau ntawm koj lub vaj huam sib luag. Nws kuj yog nyob ntawm kev sib dhos tshuab. Daim duab 4. qhia txog haujlwm ntawm fiducial cim rau ntawm ntug vaj huam sib luag.
