Hauv kev tsim khoom ntawm PCBASMT tshuab, qhov tawg ntawm cov khoom siv nti yog muaj nyob rau hauv multilayer nti capacitor (MLCC), uas yog tshwm sim los ntawm thermal stress thiab mechanical stress.
1. STRUCTURE ntawm MLCC capacitors yog qhov tsis yooj yim heev.Feem ntau, MLCC yog ua los ntawm ntau txheej ceramic capacitors, yog li nws muaj lub zog qis thiab yooj yim rau kev cuam tshuam los ntawm cua sov thiab cov neeg kho tshuab quab yuam, tshwj xeeb tshaj yog nyob rau hauv yoj soldering.
2. Thaum lub sij hawm SMT txheej txheem, qhov siab ntawm z-axis ntawm lubxaiv thiab tso tshuabyog txiav txim los ntawm lub thickness ntawm cov nti Cheebtsam, tsis yog los ntawm lub siab sensor, tshwj xeeb tshaj yog rau ib co ntawm cov SMT tshuab uas tsis muaj lub z-axis soft landing muaj nuj nqi, yog li ntawd lub cracking yog tshwm sim los ntawm lub thickness kam rau ua ntawm lub Cheebtsam.
3. Buckling kev nyuaj siab ntawm PCB, tshwj xeeb tshaj yog tom qab vuam, yuav ua rau tawg ntawm cov khoom.
4. Qee cov khoom siv PCB yuav raug puas tsuaj thaum lawv muab faib.
Kev tiv thaiv:
Ua tib zoo kho cov txheej txheem vuam nkhaus, tshwj xeeb tshaj yog qhov kub ntawm qhov chaw preheating yuav tsum tsis txhob qis dhau;
Qhov siab ntawm z-axis yuav tsum tau ua tib zoo kho hauv lub tshuab SMT;
Lub cutter zoo li jigsaw;
Qhov curvature ntawm PCB, tshwj xeeb tshaj yog tom qab vuam, yuav tsum tau kho kom raug.Yog tias qhov zoo ntawm PCB yog qhov teeb meem, nws yuav tsum tau txiav txim siab.
