North American PCB Kev Lag Luam Muag Khoom nce 1 feem pua ​​thaum lub Kaum Ib Hlis

IPC tshaj tawm Lub Kaum Ib Hlis 2020 kev tshawb pom los ntawm nws North American Luam Ntawv Circuit Board (PCB) Cov Kev Ntsuas. Tus lej ntawm phau ntawv-rau-tus nqi nyob ntawm 1.05.

Tag nrho North American PCB cov khoom xaib thaum Lub Kaum Ib Hlis 2020 tau nce 1.0 feem pua ​​piv rau lub hlis dhau los. Muab piv rau lub hli dhau los, kev xa khoom thaum lub Kaum Ib Hlis poob 2.5 feem pua.

Cov ntawv PCB nyob rau lub Kaum Ib Hlis tau nce 17.1 feem pua ​​nyob rau xyoo thiab nce 13.6 feem pua ​​ntawm lub hli dhau los.

"PCB xa khoom thiab kev txiav txim txuas mus ntxiv qee qhov tsis yooj yim tab sis tseem nyob rau hauv txoj kab nrog cov kev hloov tshiab," Shawn DuBravac, IPC tus thawj coj ua lag luam. "Thaum xa khoom poob qis me ntsis qis dua qhov nruab nrab tsis ntev los no, cov xaj tau nce siab dhau ntawm lawv qhov nruab nrab thiab yog 17 feem pua ​​siab dua xyoo dhau los."

Cov ntaub ntawv muaj txhij txhua
Cov tuam txhab uas koom nrog IPC ntawm North American PCB Qhov Kev Pabcuam muaj peev xwm nkag tau rau cov ncauj lus kom ntxaws txog kev txhav PCB thiab cov muag khoom thiab cov xaim hluav taws xob yooj yim, suav nrog rau cov khoom lag luam sib txawv thiab flex phau ntawv-rau-daim nqi sib tw, cov kev loj hlob los ntawm cov khoom lag luam thiab cov tuam txhab loj, kev thov ua ntej , muag kev loj hlob mus rau kev lag luam tub rog thiab kev kho mob, thiab lwm yam ntaub ntawv kom raws sijhawm.

Txhais cov ntaub ntawv
Daim ntawv teev cov nqi mus rau kev txiav txim siab tau suav los ntawm kev faib cov nqi ntawm cov ntawv xaj cia hauv peb lub hlis dhau los los ntawm tus nqi ntawm kev muag khoom hauv tib lub sijhawm los ntawm cov tuam txhab hauv IPC qhov kev tshawb fawb piv txwv. Ib qho kev piv ntawm ntau dua 1.00 pom tias cov kev xav tau tam sim no yog qhov ua ntej ntawm qhov khoom xa tuaj, uas yog qhov taw qhia zoo rau kev muag khoom loj dua peb lossis kaum ob hlis tom ntej no. Qhov piv ntawm tsawg dua 1.00 qhia tau tias qhov hloov rov qab.

Kev lag luam thawm xyoo thiab xyoo-rau-hnub nthuav dav pom cov ntsiab lus tseem ceeb tshaj plaws ntawm kev lag luam kev loj hlob. Kev sib piv lub hli dhau ib hlis yuav tsum ua nrog ceev faj thaum lawv xav txog kev cuam tshuam txog lub caij nyoog thiab qhov tsis hloov sai. Vim tias bookings zoo li tsis muaj qhov pauv ntau dua li kev xa khoom, kev hloov pauv ntawm phau ntawv-rau-daim ntawv teev nyiaj los ntawm ib hlis mus rau ib hlis yuav tsis tseem ceeb tshwj tsis yog tias muaj kev tshaj li peb lub hlis sib law liag. Nws tseem yog ib qho tseem ceeb uas yuav tsum xav txog kev hloov pauv hauv ob qho kev hloov pauv thiab kev xa mus los kom nkag siab txog dab tsi yog kev hloov pauv ntawm kev hloov phau ntawv-rau-tus nqi.
