Hauv qab no yog nws cov ntaub ntawv tseem ceeb:
- Khoom siv
Internal Core: PCB (Printed Circuit Board), nws cov khoom siv yog fiberglass + epoxy resin. Nws yog nruab nrog cov khoom siv hluav taws xob xws li chips (silicon-based semiconductors) thiab capacitors / resistors (ua los ntawm cov khoom siv ceramic / hlau).
Plhaub: Aluminium alloy (qhov saum npoo yuav raug tshuaj tsuag / anodization kev kho kom ua tiav cov cua sov dissipation thiab electromagnetic shielding teebmeem).
Cov Khoom Pab Txhawb: Lub npoo ntawm PCB yog coated nrog cov xim tiv thaiv (rau ya raws / corrosion kuj), thiab sab hauv ntawm lub plhaub yuav tsum tau ntim nrog potting compound (rau kev txhim kho thiab rwb thaiv tsev).
- Txheej txheem ntau lawm
PCB Manufacturing: Cov khoom txiav → Drilling → Copper deposition → Etching → Surface treatment (immersion gold/OSP).
Component Assembly:
Solder paste printing → SMT (Nto Mount Technology) tso (rau mounting me me Cheebtsam xws li chips thiab resistors) → Reflow soldering (rau soldering thiab kho).
Qee cov khoom siv hauv lub qhov tau txais THT (Through-Hole Technology) ntxig + Wave soldering.
Kev soj ntsuam cov txheej txheem: Solder paste tshuaj xyuas (SPI), kev tshuaj ntsuam xyuas qhov chaw (AOI), nyob rau hauv-circuit test (ICT), thiab high-potential test (Hi-Pot).
Tom qab ua tiav: Txau cov xim tiv thaiv → Plhaub sib dhos (kev sib khi thiab ntsia hlau kho).
- Muaj nuj nqi
Raws li "lub hlwb hluav taws xob" ntawm lub tsheb, nws yog lub luag haujlwm tseem ceeb rau:
Regulating tsis xws li lub cav roj txhaj tshuaj, ignition lub sij hawm, thiab cua kom tsawg npaum li cas los optimize lub hwj chim kev ua tau zoo thiab roj efficiency.
Kev saib xyuas lub sijhawm tiag tiag ntawm lub tsheb kev ua haujlwm, sau cov ntaub ntawv sensor (xws li, kev sib hloov ceev, qhov kub thiab txias), thiab ua qhov kev kuaj xyuas tsis raug thiab ceeb toom ntxov.
Qee cov qauv kuj koom nrog hauv kev ua haujlwm xws li kev tswj kev sib kis thiab kev tswj emission.
