Txhawm rau kom tsis txhob muaj qhov yuam kev thaum lub sijhawm sib dhos PCB, cov ntsiab lus hauv qab no yog qhov tseem ceeb.

Ib. Muab tag nrho PCB fabrication cov ntaub ntawv ntau lawm rau cov chaw tsim khoom

BOM lis

Gerber

Pnp file

PCBA xeem cov ntaub ntawv

Ob. PCB tsim thiab sib dhos kos duab

Specification ntawm PCB liab qab board:

Drilling ib qhov

Daim duab qhia qhov

Cov txheej yog stacked

Cov ntawv sau (PCB cov khoom thiab thickness, tooj liab hnyav, kam rau ua, Nto tiav, thiab tshwj xeeb yuav tsum tau)

Cov lus qhia ntawm Circuit Board Assembly:

Circuit Board Txheej txheem cej luam

Cov duab puab

Daim Ntawv Pov Thawj

Mechanical Parts

Cov lus qhia ua ke

Sau ntawv ntxiv

Expanded Hla-Section Saib

Daim Ntawv Qhia Tag Qhov Chaw

Peb. Kho PCB los ua ke

Plaub. Xyuas kom tseeb tias lub silkscreen yog pom meej

Tsib. Xyuas kom tseeb tias lub silkscreen yog pom meej

Rau, Txheeb xyuas qhov polarity ntawm cov khoom siv hluav taws xob

Cov cathode thiab anode raug txheeb xyuas ntawm cov khoom xws li electrolytic capacitors, leds, diodes thiab ics

 

Xya. Tshem tawm cov khoom siv hluav taws xob tsis muaj hlau lead thiab tsis muaj hlau lead

Xya. Qhov sib txawv ntawm qhov sib txawv

Tsis txhob muaj teeb meem ntawm qhov sib nrug ntawm cov khoom thaum sib dhos

 

Yim.Cov khoom loj yog muab tso rau sib npaug

Cov khoom loj yog muab tso rau sib npaug kom cov cua sov tuaj yeem sib npaug thaum lub sij hawm reflow soldering, thiab cov chaw tsim khoom PCBA yuav teeb tsa lub tshav kub nkhaus ntawm reflow soldering.

Cuaj.DFMTshawb xyuas

Design for Manufacturability (DFM) checks tuaj yeem txheeb xyuas cov qauv tsim tsis raug thaum ntxov thiab tiv thaiv cov teeb meem xws li kev kho dua tshiab tom qab.
