Lub niam ntawv (tej zaum kuj yog hu ua pawg thawj coj, lub rooj tsav xwm saib xyuas, kev sib tw ua haujlwm board, los yog kev sib koom tes) yog pawg thawj coj saib kev sib tham (PCB) muaj nyob hauv cov computers thiab lwm lub tshuab. Nws tuas thiab tso cai rau kev sib txuas lus ntawm ntau ntawm cov khoom tseem ceeb hauv ib qho system, xws li chav ua haujlwm (CPU) thiab kev nco, thiab muab cov khoom sib txuas rau lwm tus neeg. Tsis zoo li ib lub phom rov qab, lub niam ntawv muaj ib qho tseem ceeb hauv lub tshuab xws li tus processor thiab lwm yam. Thaum koj txiav txim siab PCBs los ntawm Uniwell circuits, koj yuav tau txais kev them nqi rau nws tus kheej lub sijhawm dhau los. Qhov no yog guaranteed los ntawm ib cov khoom specification thiab kev tswj kom zoo uas yog deb dua nruj dua lwm tus neeg siv khoom, thiab xyuas kom meej tias cov khoom yuav muab tau nws cov lus cog tseg.

3.FAQ
Q: Hom kev pab cuam dab tsi?
Yuav kom paub tseeb tias qhov zoo tshaj plaws, peb muab cov lus sib tw hauv qab no los lav txhua yam khoom:
1) AOI (Automated Optical Inspection)
2) Tsis pub kuaj qhov kev ntsuas luv luv
3) RoHS ntsuas
4) Dielectric tester
5) Kev tswj hwm kev puas ntsoog
6) Metallographic microscope
7) Ya sojntsuam / ncaws pob pwm
8) Kev kuaj pom
Lus Nug: Lub pob ntawm cov khoom siv?
Peb siv lub tshuab nqus tsev vacuum.
Q: Qhov chaw me me yog qhov microvia?
Raws li lub ntsiab lus tshiab hauv IPC-T-50M tus microvia yog ib qhov muag tsis pom kev nrog qhov siab tshaj plaws ntawm 1: 1, xaus rau ntawm lub teb chaws uas muaj tag nrho qhov tob tsis tshaj li 0.25mm ntsuas los ntawm tus qauv ntes cov av ntim ntawv lub hom phiaj rau thaj av.
