23. Tsis muaj vuam
Tsis muaj tin nruab nrab ntawm tus pin tivthaiv thiab cov ntaub qhwv los yog tsis muaj kev sib txuas rau lwm yam laj thawj.
24.Reflow Qhov cubKev vuam cuav
Tus nqi ntawm cov tin nruab nrab ntawm tus pin tivthaiv thiab cov ntaub so ntswg yog me me, uas yog qis dua tus qauv vuam.
25. txias vuam
Tom qab lub solder muab tshuaj yog kho, muaj ib tug vague particle txuas rau ntawm lub solder ncoo, uas tsis yog raws li tus qauv vuam.
26. Qhov tsis ncaj ncees lawm
Qhov chaw tsis raug ntawm cov khoom siv vim yog BOM, ECN yuam kev, lossis lwm yam laj thawj.
27. Yam tsis muaj
Yog tias tsis muaj cov khoom siv soldered qhov twg cov khoom yuav tsum tau soldered, nws yog hu ua ploj lawm.
28. Tin slag tin pob
Tom qab vuam ntawm PCB pawg thawj coj saib, muaj cov tin slag tin pob ntxiv rau ntawm qhov chaw.
29. ICT xeem
Tshawb xyuas qhib Circuit Court, luv Circuit Court thiab vuam ntawm tag nrho cov Cheebtsam ntawm PCBA los ntawm kev sojntsuam sojntsuam tiv tauj point.Nws muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim, ceev thiab raug qhov chaw txhaum
30. FCT test
FCT xeem feem ntau hu ua kev xeem ua haujlwm.Los ntawm kev simulating ib puag ncig kev ua haujlwm, PCBA yog nyob rau hauv ntau lub xeev tsim ntawm kev ua haujlwm, txhawm rau kom tau txais cov kev txwv ntawm txhua lub xeev los txheeb xyuas cov haujlwm ntawm PCBA.
31. Kev kuaj kev laus
Hlawv-hauv kev sim yog simulate cov teebmeem ntawm ntau yam ntawm PCBA uas yuav tshwm sim hauv kev siv tiag tiag ntawm cov khoom.
32. Vibration test
Kev vibration test yog los ntsuas qhov kev tiv thaiv kev vibration muaj peev xwm ntawm simulated Cheebtsam, cov khoom seem thiab ua tiav cov khoom siv tshuab hauv ib puag ncig siv, kev thauj mus los thiab kev teeb tsa.Lub peev xwm los txiav txim seb cov khoom puas tuaj yeem tiv taus ntau yam ntawm ib puag ncig kev co.
33. Kev sib dhos tiav
Tom qab ua tiav ntawm kev xeem PCBA thiab lub plhaub thiab lwm yam khoom siv tau sib sau ua ke los tsim cov khoom tiav.
34. IB
IQC yog lub ntsiab lus ntawm "Incoming Quality Control", hais txog Kev Tshawb Fawb Txog Kev Ua Haujlwm Zoo, yog lub tsev khaws khoom los yuav cov khoom Tswjhwm Zoo.
35. X – Ray detection
X-ray nkag mus yog siv los kuaj xyuas cov qauv sab hauv ntawm cov khoom siv hluav taws xob, BGA thiab lwm yam khoom.Nws kuj tseem tuaj yeem siv los txheeb xyuas qhov vuam zoo ntawm cov pob qij txha.
36. steel mesh
Cov hlau mesh yog pwm tshwj xeeb rau SMT.Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau muab tshuaj txhuam.Lub hom phiaj yog txhawm rau hloov tus nqi pes tsawg ntawm cov tshuaj pleev xim rau qhov chaw nyob ntawm PCB pawg thawj coj saib.
37. kev sib tw
Jigs yog cov khoom uas yuav tsum tau siv nyob rau hauv cov txheej txheem ntawm batch ntau lawm.Nrog kev pab los ntawm kev tsim cov jigs, cov teeb meem ntau lawm tuaj yeem txo qis heev.Jigs feem ntau muab faib ua peb pawg: txheej txheem sib dhos jigs, qhov project test jigs thiab circuit board test jigs.
38. PIB
Kev tswj hwm zoo hauv PCBA kev tsim khoom.
39. OQA
Kev tshuaj xyuas zoo ntawm cov khoom tiav thaum lawv tawm hauv lub hoobkas.
40. DFM manufacturability check
Optimize cov khoom tsim thiab tsim cov qauv, txheej txheem thiab raug ntawm cov khoom.Tsis txhob raug tsim txom.
