7. Ka dib marka la xaqiijiyo saxnaanta template PCB, waxaa ugu wanaagsan in la xiro feylka qaabdhismeedka si looga fogaado in dhaqaaqo xumeyn

Marka labaad, ka dib marxaladda kormeerka qaabaynta

A. Hubi qaybaha

14. Waxaa fiican in la xiro aaladaha la xiriira qaab-dhismeedka ka dib marka la habeeyo si looga hortago in tabar-darrida ay u guurto booska

15. Within 5mm around the crimping socket, the front side is not allowed to have components whose height exceeds the height of the crimping socket, and the back side is not allowed to have components or solder joints

16. Xaqiiji in qaabka aaladda uu buuxiyey shuruudaha farsamada (diiradda saar BGA, PLCC iyo godka balastarka)

17, qaybaha qolofka birta ah, fiiro gaar ah u yeelo inaadan ku dhicin qaybaha kale, si aad uga tagto boos bannaan oo kugu filan

18. Qaybaha la xiriira wejiga waa in la dhigaa meel u dhow is-dhexgalka, iyo darawalka baska diyaaradda ee dambe waa in la dhigaa meel u dhow isku xiraha diyaaradda

19. Haddii aaladda CHIP ee dusha alxanka mawjadda loo beddelay xirmo alxanka mawjadda,

20. Whether there are more than 50 manual solder joints

21. Ku -fidinta tooska ah waa in loo tixgeliyaa kor -u -qaadista axial ee qaybaha sare ee PCB. Leave room for sleeping. Oo tixgeli habka go’an, sida suufka go’an ee kristal

22. Hubi inay jirto kala -fogaansho ku filan oo u dhexeysa aaladaha isticmaalaya weelka kuleylka iyo aaladaha kale, oo fiiro u yeelo dhererka aaladaha waaweyn ee ku jira baaxadda weelka kuleylka

B. Hubinta shaqada

23. Whether the layout of digital circuit and analog circuit components of the digital-analog hybrid board has been separated, and whether the signal flow is reasonable

24, A/D baddelayaashu waxay ku yaalliin qeybaha analogga ah.

25, clock device layout is reasonable

26. Whether the layout of high-speed signal devices is reasonable

27, haddii aaladda terminaalka si habboon loo meeleeyay (iska -caabbinta taxanaha is -waafajinta waa in la dhigaa dhammaadka darawalnimada; The intermediate matching string resistance is placed in the middle position; Diidmada taxanaha isbarbar -dhigga waa in lagu dhejiyaa dhammaadka helitaanka signalada)

28. Haddii tirada iyo meesha kala -guurinta capacitors -yada IC ay yihiin kuwo macquul ah

29. Khadadka calaamaduhu waxay u qaataan diyaarado heerar kala duwan leh sida diyaaradaha tixraaca. Markaad ka gudbeyso gobolka oo ay u qeybsan yihiin diyaarado, haddii awoodda isku xirka ee u dhexeysa diyaaradaha tixraaca ay u dhowdahay gobolka isgaarsiinta signalada.

30. Haddii qaabeynta wareegga ilaalintu ay tahay mid macquul ah oo ku habboon qaybinta

31. Haddii fiyuuska korontada ee boodhka la dhigo meel u dhow isku xiraha oo aysan jirin qayb wareeg ah horteeda
