Qhov tseem ceeb ntawm PCB Nqe Ntsiab
May 29, 2018

Yog li cas tiag tshua tus nqi ntawm cov nqi Circuit Court laug cam?

Cov lus teb rau ntau tshaj li tsis yog, "nws nyob ntawm," cia khawb me ntsis thiab sib tham txog cov ntsiab lus tseem ceeb ...
Tsav tsheb.
1. Lub hauv paus thiab tus naj npawb ntawm cov khaub ncaws
2. Qhov loj ntawm PCB
3. Kev Siv Vaj Huam Sib Luag & Tus Naj Npawb ntawm PCB Tus Qauv Ua Haujlwm (Tus Qauv 18 x 24)
4. Qhov Chaw, Qhov Nyhav, Qhov Drilling Technology
5. Lw Kab Ntsig & Txwv
6. Xaus
7. Pib Cov Khoom Siv Laminate
8. Tooj Liab & Thickness ntawm Board
9. Routing lossis Die Punching ntawm PCB Profile
10. Cov Nqi Qis
1. Lub hauv paus thiab tus naj npawb ntawm cov khaub ncaws
Nquag muaj FR4 FR5 CAM1 CAM3 Txhuas los luj, tooj liab, thiab zawj khaub zawg thiab zoo li ntawd, nws yog qhov yooj yim to taub
tias tus nqi isdifferent. Cov naj npawb ntawm cov khaubncaws sab nraud yog nyob ntawm cov theem ntawm PCB xwb. Tsuas yog, ntau dua
cov txheej txheej, ntau cov nqi yuav tsim.
2. Qhov loj ntawm PCB - Qhov teeb meem loj ... qhov loj ntawm qhov loj ntawm lub rooj tsavxwm, cov khoom siv ntau yuav tsum tau tsim lawv.
3. Kev Siv Vaj Huam Sib Luag - Qhov no yog hais txog cov "arrays" ... pes tsawg PCBs ib qho tuaj yeem raug tsim tawm ntawm lub rooj haujlwm ua haujlwm.
Qhov no xam los ntawm cov feem pua ntawm kev siv uas yog xam los ntawm tag nrho thaj chaw rau PCB muab faib los ntawm tag nrho cov vaj huam sib luag
cheeb tsam (raws li qhov 18 x 24 cov haujlwm ua haujlwm). Qhov siab tshaj qhov kev siv vaj huam sib luag feem pua qis dua tag nrho cov nqi. A
qhov kev zov me nyuam nrog kev siv tshaj 75% yog qhov zoo. Cov nta uas yuav tsum tau muab suav rau hauv xam muaj xws li,
siv qhov, qhov kev xaib, daim coupon, thiab kev sib tw ntawm txoj hlua raws li qhov yuav tsum tau ua. Cias muab, tau 4 +
luam tawm Circuit Court boards ib array yog npaum li cas.
4. Tawm Tsawg, Qhov Cug, & Drilling - Ntau qhov, thiab ntau qhov ntawm qhov qhov ntev yog qhov tseem ceeb tshaj plaws
ntawm cov nqi PCB. Nyob ntawm seb muaj pes tsawg leej thiab qhov sib npaug ntawm txhua txoj kab uas sib npaug sib npaug rau lub tshuab ntev dua
sijhawm, thiab kev siv ntau cov khoom siv, kev nce nqi. Yog tias qhov me me raws li cov me me, laser drilling yuav yog
tsim nyog thiab ntxiv qhov tseem ceeb.
5. Kev Laj Kab Ntsis & Hloov Kab Qhov dav ntawm tus neeg "qhov chaw" (xav tias tam sim no txuas) thiab nyob sib ze npaum li cas rau txhua
lwm yam ntawm ib txoj kab ntawm ntug lem mus cuam tshuam ntug yuav cuam tshuam tus nqi raws li cov duab thiab plating khoom los yog txheej txheem
muaj peev xwm. Qhov dav hlau qhov dav, qhov nce hauv koj tus nqi PCB.
6. Cov Kev Xaus - Cov hom ntawm nplai tiav teev yuav cuam tshuam koj cov nqi raws li cov khoom siv, thiab zoo li
txoj kev tsim tau los tsim cov laug cam. Taug Txhuas Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tawm Dawb -
tus nqi qis tshaj, lwm yam, tom qab immersion tin, immersion silver, organic solder preservative OSP, kub kub,
immersion kub, tuab kub. Muaj ntau qhov kev siv ntau qhov kev sib tw, txhua tus uas muaj nws tus kheej
qhov zoo thiab qhov tsis zoo uas yuav tsum tau ua los ntawm kev txiav txim siab ua ntej yuav txiav txim siab ntawm ib qho kev ua tiav ntawm qhov chaw.
Cov neeg muab kev pabcuam nrog kev txhawb thiab kev txhawb kev tsim qauv yuav pab tau txiav txim siab tus nqi them tus nqi tseem ceeb no.
7. Txuj Laminate - Cov ntaub ntawv laminate uas tau teev muaj yuav cuam tshuam koj cov nqi. Kuv pom zoo kom koj tus PCB
tus neeg muag khoom siv lub laminate uas lawv tab tom siv thiab paub, piv txwv tias nws tau raws li koj cov lus qhia.
8. Tooj Liab & Thickness
Cov tooj liab hauv PCB yog ntsuas hauv ounces, thiab nruab nrab yog cov tuab ntawm 1 ounce ntawm tooj tooj dov tawm rau thaj tsam ntawm
1 square taw. Piv txwv - ib qho PCB uas siv 1 oz. tooj liab muaj ib tug tuab ntawm 1.4 mils. Lub hauv paus tooj liab thickness siv,
lossis ntau npaum li cas cov khoom yuav tsum tau platted mus kom raws li cov thickness yuav tsum yuav koj tus nqi. Feem ntau qhov
Qhov kev xaiv qis tshaj yog 1/2 oz ntawm tooj, thiab feem ntau yuav nce ntxiv ntawm 1 oz. increment txog li 9 oz. Feem ntau
cov laug cam poob rau hauv 1 - 2 ooj. ntau li ntau txoj cai. · 1/2 oz. = 0.7 mils · 1 oz. = 1.4 mils · 2 oz. = 2.8 mais
9. Routing or Die Punching PCB Profile Muaj ntau txoj kev siv los tshem tawm cov khoom siv laminate los tsim
qhov profile ntawm PCB. Lub ntsiab lus tseem ceeb yog "routing," uas sib txuas nrog lub siab ceev routing me ntsis cutter kom tshem tawm cov
cov ntaub ntawv laminate. Lwm txoj kev yog los ntawm ua punch uas yuav tshem tawm cov laminate thaum lub punch
txheej txheem. Feem ntau cov txheej txheem punch yog qhov kev xaiv qis dua, tab sis nws yuav muaj qee qhov cuab yeej siv ntxiv los tsim
punch cuab yeej.
10 Cov Nqi Siv Zog - Tshaj haujlwm ua haujlwm tsawg kawg yog qhov tseem ceeb hauv kev tsim cov ntawv cog lus sab nraud. Feem coob ntawm pawg txwj laus
cov chaw koom ua ib qho kev tsim cov khoom tsim tawm, uas yuav tsum tau muaj kev tuav tswv yim rau txhua tus
tus neeg ua haujlwm, nrog rau kev hloov cov khoom ntawm txheej txheem. Siv cov nqi qis dua
kev tsim cov chaw, cov lag luam, yuav muaj peev xwm pom tau tias qis dua ib tus nqi. Lwm yam khoom uas yuav cuam tshuam koj
cov nqi xws li qib IPC tus qauv ntawm pawg thawj coj saib yuav raug tsim ua, piv txwv, IPC
Chav kawm 2 uas yog ib qho qauv siv thiab feem ntau siv hauv tus qauv siv hluav taws xob, ICP Hoob 3, yog nruj dua,
thiab thaum kawg cov tub rog cov qauv uas yuav muaj kev cuam tshuam rau koj cov nqi kev tswj hwm.
Yog tias koj xav paub txog kev txo koj daim ntawv tswj hwm daim ntawv txiav txim siab txog li ntawm 10%, thov email
