Silkscreen Tsim Kev Txiav Txim Siab
General Xav Tau
Qhov dav ntawm cov kab silkscreen yuav tsum muaj ntau dua 5mil. Cov neeg tsim qauv yuav tsum xyuas kom meej tias lub silkscreen
Tus cwj pwm qhov siab yog loj txaus los nyeem los ntawm qhov muag liab qab (pom zoo h 50mil).Pom zoo yov nruab nrab ntawm cov khoom silkscreen yog h 8mil.
Tus silkscreen yuav tsum tsis txhob sib tshooj nrog cov quav lossis cov Fiducials. Qhov nrug tsawg kawg ntawm ob qho yog
6mil.Dawb yuav tsum yog lub neej ntawd silkscreen number case xim. Cov kev cai tshwj xeeb yuav tsum tau teev nyob rau hauv
PCB lub laum qhov txheejRau siab-tsim PCB tsim, cov ntsiab lus ntawm silkscreen tuaj yeem xaiv raws li kev qhia tshwj xeeb
cov tseev kom muaj. Txhua cov ntawv nyeem silkscreen yuav tsum ua raws li cov lus cog tseg ntawm sab laug rau sab xis, saum toj mus rau hauv qab.
Silkscreen Txheem
Cov ntsiab lus ntawm lub silkscreen tuaj yeem suav nrog PCB lub npe, version, feem tivthaiv tooj, polarity thiab
cov kev taw qhia cov ntawv cim, barcode lub thawv, lub qhov rooj pob qhov chaw nyob qhov chaw, tiv thaiv hneev taw, pawg thawj coj ntawm kev taug kev
qhov taw qhia, daim ntawv lo los tiv thaiv zoo li qub, daim ntawv lo rau cua sov, thiab lwm yam
PCB npe thiab version:
Lub npe ntawm cov thawj coj thiab cov ntawv yuav tsum muab tso rau sab saum toj ntawm PCB. Tus font yuav tsum tau xaiv xws tias nws tuaj yeem nyeem tau yooj yim. Sab sab saum toj thiab hauv qab ntawm PCB tseem yuav tsum tau cim nrog 'T' thiab 'B' (lossis zoo sib xws).
Barcode (tsis teb los tau):
Tus lej barcode yuav tsum tau muab kev cob qhia tav toj los yog tshaj rau ntawm PCB, tsis kam rau kev qhia lub
barcode ntawm lwm lub kaum sab xis.
Qhov pom zoo ntawm txoj cai bar rau ntawm lub rooj tsav xwm raug yog qhia hauv daim duab hauv qab no; tus
txoj hauj lwm ntawm cov laug cam uas tsis yog txheem siv tau qhov no rau kev siv.
Tshuaj ntsuam tiv thaiv txhob lo lo ntxhuav:
Cov ntawv sib dhos, qhov chaw ua haujlwm thiab qhov chaw muab khoom siv yuav tsum tau qhia rau ntawm silkscreen kom meej meej
thiab yuav tsum nyob ntawm cov yam ntxwv cuam tshuam.Cov ntawv cim Silkscreen, daim duab ntxoo thiab cov kev taw qhia yuav tsum tsis txhob npog los ntawm cov khoom sib xyaw.
Rau cov khoom siv ntsia tau tav toj (xws li dag electrolytic capacitors), silkscreen yuav tsum
suav sau lub ntsiab lus tivthaiv rau ntawm txoj haujlwm ua haujlwm.
Mounting qhov, qhov taw qhia:
Nws raug nquahu tias cov chaw ntawm lub qhov mounting thiab qhov pilot ua ntawm PCB tau sau tias "M **" thiab "P **," feem.
Kev Ncig Tebchaws:
Rau cov PCBs uas yuav tsum tau txau rau hauv cov cuab yeej siv, xws li cov khoom siv yoj khoom siv, hauv ib qho tshwj xeeb
kev cob qhia, qhov kev taw qhia ntawm kev mus ncig yuav tsum tau qhia ntawm daim txiag. Qhov no kuj tsim nyog rau PCBs nrog cov tub sab uas muag thiab teardrop solder ncoo.
Heatsink:
Rau lub hwj chim PCBs uas yuav tsum muaj lub heatsink, yog tias thaj chaw npaj ntawm lub heatsink yog loj dua li cov khoom siv, qhov tseeb loj yuav tsum tau hais tawm ntawm qhov silkscreen.
Anti-Static Label:
Cov tshuaj tiv thaiv kab mob lo lo ntxhuav los tiv thaiv zoo li qub yuav tsum tau muab tso rau sab saum toj ntawm PCB sab nraud.
