Cov txheej txheem tseem ceeb ntawm PCB los ua ke

PCBA yog cov txheej txheem ntawm kev txuas cov khoom siv hluav taws xob rau hauv PCB.

Peb tuav tag nrho cov theem hauv ib qho chaw rau koj.

1. Solder Paste Printing

Thawj kauj ruam hauv PCB los ua ke yog kev luam ntawv ntawm cov tshuaj txhuam hniav rau hauv qhov chaw ntawm lub rooj tsavxwm PCB. Cov tshuaj txhuam hniav muaj cov hmoov tin thiab flux thiab yog siv los txuas cov khoom rau cov ntaub qhwv hauv cov kauj ruam tom ntej.

2. Nto Mounted Technology (SMT)

Surface Mounted Technology (SMT Cheebtsam) tau muab tso rau ntawm cov tshuaj nplaum uas siv cov khoom sib txuas. Ib tus neeg sib koom ua ke tuaj yeem muab cov khoom sib xyaw ua ke sai thiab raug muab tso rau hauv qhov chaw tshwj xeeb.

3. Reflow Soldering

Lub PCB nrog cov khoom txuas txuas yog dhau los ntawm qhov cub reflow, qhov twg cov khoom siv tshuaj yaj ywm yaj ntawm qhov kub thiab txias thiab cov khoom siv tau ruaj khov rau PCB. Reflow soldering yog ib kauj ruam tseem ceeb hauv SMT sib dhos.

4. Kev Tshawb Fawb Txog Kev Pom Zoo thiab Kev Tshawb Fawb Kev Siv Hluav Taws Xob (AOI)

Tom qab reflow soldering, PCBs raug kuaj pom los yog tau txais kev tshuaj ntsuam xyuas siv AOI cov cuab yeej los xyuas kom meej tias tag nrho cov khoom raug soldered kom raug thiab tsis muaj qhov tsis xws luag.

5. Thru-Hole Technology (THT)

Rau cov khoom siv uas xav tau los ntawm lub qhov tshuab (THT), cov khoom siv tau muab tso rau hauv PCB qhov los ntawm qhov yog manually lossis txiav.

6. Wave Soldering

Lub PCB ntawm cov khoom siv ntxig yog dhau los ntawm lub tshuab yoj soldering, thiab lub tshuab nthwv dej yoj welds cov khoom ntxig rau PCB los ntawm nthwv dej ntawm molten solder.

7. Kev Xeem Ua Haujlwm

Kev sim ua haujlwm tau ua tiav ntawm PCB sib dhos kom ntseeg tau tias nws ua haujlwm zoo hauv daim ntawv thov tiag tiag. Kev sim ua haujlwm tuaj yeem suav nrog kev ntsuas hluav taws xob, ntsuas teeb liab, thiab lwm yam.

8. Kev soj ntsuam zaum kawg thiab kev tswj xyuas zoo

Tom qab tag nrho cov kev ntsuam xyuas thiab kev sib dhos ua tiav, kev tshuaj xyuas zaum kawg ntawm PCB yog ua los xyuas kom meej tias tag nrho cov khoom raug teeb tsa raug, tsis muaj qhov tsis xws luag, thiab ua raws li cov qauv tsim thiab cov qauv zoo.

9. Ntim thiab Shipping

Thaum kawg, PCB uas tau dhau qhov kev kuaj xyuas zoo tau ntim los xyuas kom meej tias lawv tsis raug puas tsuaj thaum thauj mus los thiab xa mus rau cov neeg siv khoom.
