Qhov Twg Ntawm Ib-Qhov Chaw Tsim Tshuaj PCBA Ua Ib Zaug Yuav Tsum Raug Them Qhia Txiaj Ntsig Zoo?

Cov xwm txheej ntawm kev ua tiav ib qho PCBA ua ib zaug yuav tsum tau them sai sai los xyuas kom meej zoo?

1. SMT thaj

Muaj ob lub ntsiab lus tseem ceeb hauv kev tsim cov khoom lag luam PCBA, uas yog cov kev tiv thaiv kev tiv thaiv zoo kom paub meej cov ham muab cov ntawv luam tawm thiab reflow kub tswj hauv SMT nti ua. Thiab thaum luam tawm high-precision Circuit Board rau cov txheej txheem tshwj xeeb thiab cov txheej txheem, txhawm rau ua kom tau raws li cov kev xav tau, laser stencils yuav tsum tau siv raws li cov kev mob tshwj xeeb. Thiab raws li PCB tsim kev xav tau thiab cov neeg siv cov khoom lag luam, qee qhov yuav tsum tau nce U-puab lub qhov lossis txo qis hlau mesh qhov.

Thaum ua tiav qee qhov kev kho mob ntawm qhov stencil ntau lawm ntawm PCBA ua cov thev naus laus zis, kev tswj qhov kub thiab txias qhov tseeb ntawm lub qhov cub ci ntsa rau nws yog qhov tseem ceeb heev rau qhov ntub dej ntawm qhov muab tshuaj txhuam thiab khov kho ntawm stencil vuam, thiab tuaj yeem kho raws li kev ua haujlwm SOP li qub. phau ntawv qhia. Txhawm rau txo qis qhov tsis zoo ntawm PCBA thaj tus nqi hauv SMT qhov txuas. Ntxiv rau, kev siv nruj ntawm kev xeem AOI tuaj yeem txo ntau qhov tsis xws tshwm sim los ntawm tib neeg yam.

Ob, DIP ntsaws-tom qab vuam

Ib qho ntawm cov tseem ceeb tshaj plaws thiab cov txheej txheem kawg hauv Circuit Court board ua theem yog post-dip soldering. Nyob rau hauv cov txheej txheem ntawm DIP ntsaws-tom qab-vuam, qhov kev xav ntawm lub tshuab ua kom sov jig rau yoj soldering yog qhov tseem ceeb heev. Yuav ua li cas siv cov hluav taws xob ua kom sov tau zoo rau cov txiaj ntsig cov txiaj ntsig, txo cov teeb meem soldering xws li tin txuas ntxiv, pib me me thiab tsis txaus, thiab raws li qhov sib txawv ntawm cov neeg yuav khoom cov khoom lag luam, pcba ua cov nroj tsuag yuav tsum txuas ntxiv cov ntsiab lus hauv kev coj ua, thiab tsim hauv kev paub Tus txheej txheem ua tiav txheej txheem thev naus laus zis.

Thib peb, sim thiab qhov kev tua tawm haujlwm

Daim ntawv qhia cov khoom lag luam yog kev tshuaj xyuas kev ua haujlwm uas peb yuav tsum ua ua ntej tag nrho kev tsim khoom tom qab tau txais daim ntawv cog lus ntawm cov neeg siv khoom. Hauv daim ntawv tshaj tawm DFM dhau los, peb tuaj yeem muab qee cov lus qhia rau cov qhua tuaj noj mov ua ntej cov txheej txheem PCB, xws li Teeb tsa qee qhov ntsuas qhov tseem ceeb ntawm PCB (qhov chaw ntsuas) rau qhov ntsuas tseem ceeb ntawm kev txuas ntxiv thiab txuas txuas ntawm Circuit Court tom qab PCB soldering xeem thiab PCBA tom qab ua ntxiv. Thaum muaj kev tso cai, koj tuaj yeem sib txuas lus nrog cov qhua tuaj noj mov los muab cov kev pab cuam rov qab, thiab tom qab ntawd hlawv cov haujlwm PCBA rau hauv cov tub ntxhais tseem ceeb IC los ntawm lub tshuab hlawv. Ua li no, lub rooj tsav xwm hauv Circuit Court tuaj yeem raug sim ntau dua ntawm kev ua kov, yog li kev ncaj ncees ntawm tag nrho PCBA tuaj yeem kuaj thiab tshuaj xyuas, thiab cov khoom tsis raug tuaj yeem pom lub sijhawm.

Plaub, PCBA xeem

Ib qho ntxiv, ntau tus neeg muas zaub nrhiav qhov chaw nres tsheb hauv PCBA muab cov kev pab cuam kuj tseem muaj rau PCBA qhov kev xeem rov qab. Cov ntsiab lus ntawm hom kev ntsuas no feem ntau suav nrog ICT (kev ntsuam xyuas Circuit Court), FCT (kuaj ntsuas), ntsuas kub (kev ntsuas kev laus), ntsuas kub thiab av noo, ntsuas kev xeem, thiab lwm yam.

Plaub lub ntsiab lus kom ntseeg tau tias qhov zoo hauv qhov kev ua tiav PCBA ib qho kev ua tiav: SMT thaj, DIP ntsaws-tom qab vuam, kuaj kab thiab tua hluav taws, thiab kuaj PCBA tiav tiav hauv Tecoo. Tsuav cov qhua tuaj noj mov rau peb, tsis muaj qhov kev txhawj xeeb hauv kev ua raws cai.
