Circuit Board Inspection Standards
1. Lub peev xwm tsim nyog rau kev tshuaj xyuas cov xov tooj ntawm tes HDI Circuit Court boards.
2. Cov qauv qauv yuav tsum raug tshuaj xyuas raws li GB2828.1-2003, kev tshuaj xyuas dav dav II.
3. Kev tshuaj xyuas yog ua raws li cov khoom siv raw khoom specifications thiab kuaj cov qauv.
4. Cov qib tsim nyog yog raws li tus nqi AQL: Chav A = 0.01, Chav B = 0.65, Chav C = 2.5.
5. Cov cuab yeej ntsuas thiab cov khoom siv: ntsaws ntsuas, vernier caliper, reflow qhov cub, dynamometer, magnifying iav, digital multimeter, qhov kub thiab txias lub thawv, qhov tseem ceeb lub neej tester, kub-plated txheej thickness tester, tiaj marble lossis iav, rwb thaiv tsev tiv thaiv tester, qhov kub thiab txias ferrochrome.
6. Kev faib tawm tsis xws luag: Tus lej xov tooj Kev tshuaj xyuas cov khoom tsis raug piav qhia Cov ntim ntim sab nraud yog ntub dej, cov ntaub ntawv muab tso rau hauv qhov tsis zoo ntawm pawg CB Cov Lus Cim 1 Tsis muaj daim ntawv lo rau sab hauv lossis sab nraum lub pob, daim ntawv lo tsis raug, dej poob rau hauv, tsis muaj cov hlaws noo noo, tsis muaj daim ntawv humidity. , cov khoom sib xyaw, tsis muaj lub tshuab nqus tsev.
1 Daim ntawv ceeb toom xa khoom tsis tau muab.Lub Hoobkas xa khoom xa tuaj
2. Cov khoom tshuaj ntsuam xyuas hauv cov chaw tsim khoom cov khoom xa tuaj tsis zoo ib yam thiab ua tiav raws li peb cov qauv tshuaj ntsuam xyuas, cov ntaub ntawv xeem tsis tau raws li tus qauv yuav tsum tau ua, daim ntawv tshaj tawm tsis muaj kev pom zoo los ntawm tus saib xyuas zoo lossis cov neeg ua haujlwm siab dua, thiab daim ntawv tshaj tawm cov ntsiab lus tsis muaj tseeb, thiab lwm yam. Yog tias tsis tau raws li cov kev cai saum toj no.B serial tooj tshuaj xyuas cov khoom General defect piav qhia Cov khoom tuaj txawv ntawm cov qauv tsim, cov phaj sib txawv, cov phaj sib txawv (xws li tsis muaj daim ntawv cim npe), tsis muaj lub voj voog ntau lawm, thiab tsis muaj lub Hoobkas qauv.Yuav tsum tsis muaj qhov ntse ntse nyob ib puag ncig PCB los cuam tshuam rau kev sib dhos thiab ua rau tus neeg teb xov tooj raug mob.Porous thiab ob peb pores Loj thiab me pores (raws li qhov yuav tsum tau ntawm cov qauv kos duab) Muaj cov tooj liab seem nyob hauv NPTH qhov, thiab muaj oxidation hauv lub qhov.) tiav aperture: yog tshaj qhov yuav tsum tau hauv qab no
3 Drilling round qhov: NPTH: +/- 2mil (+/- 0.05mm);NPTH: tsis-sinking B tooj liab qhov;PTH: sinking tooj liab qhov PTH: +/- 3mil (+/-0.075mm) 2,
