Cov Cheebtsam ntawm PCB yog dab tsi?

1. Pauv.

Lub ncoo yog lub qhov hlau siv los ua cov pins ntawm cov khoom.

2. Txheej.

Circuit board raws li kev tsim ntawm qhov sib txawv, yuav muaj ob sab, 4-txheej board, 6-txheej board, 8-txheej board, thiab lwm yam., tus naj npawb ntawm cov khaubncaws sab nraud povtseg feem ntau yog ob npaug, ntxiv rau cov teeb liab txheej, muaj lwm yam rau lub ntsiab txhais ntawm kev ua nrog txheej.

3. Hla lub qhov.

Lub ntsiab lus ntawm perforation yog hais tias lub Circuit Court tsis tuaj yeem ua tiav ntawm ib theem ntawm tag nrho cov teeb liab kev sib raug zoo, nws yog ib qho tsim nyog los txuas cov teeb liab kab hla cov khaubncaws sab nraud povtseg los ntawm perforation, perforation feem ntau muab faib ua ob hom, ib qho rau cov hlau. perforation, ib qho rau cov non-metallic perforation, qhov twg cov hlau perforation yog siv los txuas cov khoom pins ntawm cov khaubncaws sab nraud povtseg.Daim ntawv ntawm perforation thiab txoj kab uas hla yog nyob ntawm tus yam ntxwv ntawm lub teeb liab thiab cov txheej txheem kev cog qoob loo.

4. Cheebtsam.

Soldered ntawm PCB Cheebtsam, cov khoom sib txawv ntawm kev sib xyaw ua ke tuaj yeem ua tiav cov haujlwm sib txawv, uas yog lub luag haujlwm ntawm PCB.

5. Kev sib tw.

Alignment yog hais txog cov kab teeb liab ntawm cov pins ntawm cov khoom sib txuas, qhov ntev thiab qhov dav ntawm kev sib dhos yog nyob ntawm qhov xwm txheej ntawm cov teeb liab, xws li qhov loj me, ceev, thiab lwm yam, qhov ntev thiab qhov dav ntawm qhov kev sib dhos kuj txawv.

6. Silkscreen.

Kev tshuaj ntsuam luam ntawv tseem tuaj yeem hu ua txheej txheej luam ntawv, siv rau ntau yam khoom siv ntsig txog cov ntaub ntawv sau npe, kev tshuaj ntsuam luam ntawv feem ntau yog dawb, koj tuaj yeem xaiv xim raws li lawv xav tau.

7. Solder tiv thaiv txheej.

Lub luag haujlwm tseem ceeb ntawm txheej txheej txheej yog los tiv thaiv qhov chaw ntawm PCB, tsim cov txheej txheem tiv thaiv nrog qee qhov tuab, thiab thaiv kev sib cuag ntawm tooj liab thiab huab cua.Solder resist txheej feem ntau yog ntsuab, tab sis kuj muaj xim liab, daj, xiav, dawb, dub solder resist txheej xaiv.

8. Qhov chaw qhov chaw.

Qhov chaw muab tso rau qhov yooj yim ntawm installation lossis debugging qhov.

9. Ntim.

Filling yog siv rau hauv av network ntawm tooj liab tso, tuaj yeem txo qhov impedance.

10. Hluav taws xob ciam teb.

Hluav taws xob ciam teb yog siv los txiav txim qhov loj ntawm lub rooj tsavxwm, tag nrho cov khoom ntawm lub rooj tsavxwm tsis tuaj yeem tshaj qhov ciam teb.

Cov saum toj no kaum feem yog lub hauv paus rau cov muaj pes tsawg leeg ntawm lub rooj tsavxwm, ntau nta los yog yuav tsum tau hlawv nyob rau hauv lub nti kom ua tiav qhov kev pab cuam.
