Warping ntawm lub roj teeb Circuit Court board yuav ua rau qhov chaw tsis raug ntawm cov khoom;Thaum lub rooj tsavxwm yog khoov rau hauv SMT, THT, cov khoom siv pins yuav tsis zoo, uas yuav ua rau muaj teeb meem ntau rau kev sib dhos thiab kev teeb tsa.IPC-6012, SMB-SMT Printed circuit boards muaj qhov siab tshaj plaws warpage los yog twist ntawm 0.75%, thiab lwm yam boards feem ntau tsis tshaj 1.5%;qhov tso cai warpage (ob npaug ...
- Daim phiaj tooj liab, khoom tooj liab.Qhov twg?
Copper txheej yog dab tsi?Lub npe hu ua tooj liab ncuav yog siv qhov chaw tsis siv ntawm PCB ua qhov chaw siv thiab tom qab ntawd sau nrog cov khoom tooj liab.Cov chaw tooj liab no tseem hu ua tooj liab filling.Qhov tseem ceeb ntawm cov txheej tooj liab yog txhawm rau txo qhov impedance ntawm cov xaim hauv av thiab txhim kho lub peev xwm tiv thaiv kev cuam tshuam;txo qhov hluav taws xob poob thiab txhim kho kev ua haujlwm ntawm lub zog hluav taws xob;yog tias ...
- PCB Pad loj
Thaum tsim PCB pads hauv PCB board tsim, nws yog ib qho tsim nyog yuav tsum tsim kom nruj raws li cov kev cai thiab cov qauv.Vim tias nyob rau hauv SMT thaj ua haujlwm, kev tsim ntawm PCB ncoo tseem ceeb heev.Tus tsim ntawm lub ncoo yuav cuam tshuam ncaj qha rau cov solderability, stability thiab kub hloov ntawm cov khoom.Nws muaj feem xyuam rau qhov ua tau zoo ntawm kev ua thaj chaw.Tom qab ntawd dab tsi yog PC ...
- Comparative Tracking Index ntawm PCB
Kev taug qab tsis kam ntawm tooj liab clad laminate feem ntau yog qhia los ntawm kev sib piv kev ntsuas ntsuas (CTI).Ntawm ntau yam khoom ntawm tooj liab clad laminates (tooj liab clad laminates luv luv), nrhiav kev tiv thaiv, raws li qhov tseem ceeb ntawm kev nyab xeeb thiab kev ntseeg siab, tau nce nqi los ntawm PCB Circuit board designers thiab circuit board manufacturers.Tus nqi CTI raug kuaj raws li ...
