Lub ntsiab lus: Cov Txheej Txheem Silkscreen - Lub Hom Phiaj, Khoom Siv, thiab Cov Teeb Meem Ntau
Dab tsi yog silkscreen (lus dab neeg) luam ntawv?
Cov luam ntawv Silkscreen (tseem hu ualus dab neeg luam ntawv) Yog ib kauj ruam tseem ceeb hauv PCB kev tsim khoom sivSau cov npe, cim, thiabCov qauv yooj yim Circuit Courtnyob rau hauv pawg thawj coj saibInk thiab Mesh Screen Technology.
Nws yog feem ntau siv rau:
Luam ntawvCov khoom lag luam khoom lag luam, Cov Hnub, tus logos, Cov cim, thiablus sau
Tsimblackout txheejlossisYooj Yimntawm ib lossis ob sab
Pab nrogrooj sib cai sib dhosthiabdebuggingLos ntawm kev kos cim Cheebtsam
Cov cuab yeej tseem ceeb siv:
Vijtsam Tshuab Luam Ntawv (Kos Duab Tshuab Luam Ntawv)
Qhov cub (rau thermal capte number cask)
UV Tshuab Ziab (rau UV -} Txhab NEK)
Kev Tshawb Xyuas Cov Khoom Siv
Siv los tsim cov duab thiab tsis {-} duab thaj chaw uas siv cov photoresist
Ua haujlwm ua haujlwm:
A Pre -} ci screenMuajQhib chaw rau cov ntawv thiab cov duab, thaum tus so yog thaiv nrogPaCension Emulsion.
Tus PCB yog mus raws li qhov screen sivTso PD.
A zuajPresses number cas los ntawm qhov chaw qhib ntawm lub mesh mus rau pcb nto.

Cov haujlwm tshwj xeeb no tau pom tseeb ntawm silkscreen luam ntawv sivCwj pwm lossis thaiv cov inks.
Cov teeb meem tshwm sim ntau:
| Teeb meem | Kev piav txog |
|---|---|
| Ploj lawm Sau | Ink tsis ua haujlwm hloov hauv qee thaj chaw |
| Tsis huv | Hmoov av los yog hais cuam tshuam cov ntawv luam tawm |
| Number case | Tsis tiav lossis tawg cov kab ntawv lossis cov cim |
| Ink pob | Tsa thaj chaw vim muaj cov pa tawm lossis cov khib nyiab hauv qab screen |
| Peeling / Poob Tawm | Tsis zoo adhesion nruab nrab ntawm number case thiab pawg thawj coj |
Ntsiab lus:
Cov tshuab luam ntawv Silkscreen tsis yog rau Labing - nws tseem txhawb nqa kev ua haujlwm hauv Circuit hauv cov qauv tshwj xeeb.Kev npaj tshuaj kom raug, aux xaiv, sib ncag, thiab khoyog qhov tseem ceeb heev los xyuas kom meejhigh - Cov zis zoothiab tsis txhob poob qis tsis pom kev.
