Cov lus qhia ntxaws txog tag nrho cov txheej txheem ntawm PCBA ua

1. Kev sib tham ua lag luam. Kev sib txuas lus kev lag luam yeej zoo ib yam li yav dhau los ib nrab pob hom ntawm SMT thaj thiab PCB pov thawj cais, thiab kev sib tham lag luam theem yuav tsum tau ua nyob rau theem pib. Koj paub tseeb tias kuv xav tau, kuv paub tseeb tias koj tuaj yeem ua tau. Ok, cov kauj ruam tom ntej.

2. Ntsuas cov lus hais. Ua cov khoom siv hluav taws xob tsis xav tau yuav tsum muaj qee qib kev sib txuas lus ntawm tus nqi ntawm cov khoom, tom qab tag nrho, ob tog muaj tus nqi uas yuav tsum tau ntsuas. Lub PCBA ua lub Hoobkas yuav ua qhov kev tshuaj xyuas thiab hais txuas raws li cov neeg siv khoom BOM daim ntawv thiab Gerber cov ntaub ntawv. Tom qab lees paub, txhua tus tuaj yeem mus rau kauj ruam tom ntej yam tsis muaj teeb meem.

3. Tus neeg siv khoom xaj khoom. Cov txheej txheem no yog ntau npaum li cas cov neeg siv khoom yuav tsum ua raws li lawv tus kheej cov khoom lag luam muag khoom thiab lub tuam txhab cov phiaj xwm xav tau. Yuav ua li cas muaj ntau yam khoom yuav tsum tau npaj, pes tsawg xaj yuav muab tso nrog lub pcba chaw tsim tshuaj paus. Ntawm qhov tsis sib xws, SMT qhov chaw tso khoom lag luam yuav tshuaj xyuas thiab ntsuas tus neeg siv khoom xa khoom raws li nws tus kheej lub sijhawm thiab lub peev xwm tsim khoom los txiav txim siab seb nws puas tuaj yeem ua tiav qhov kev xaj xaj xa khoom hauv lub sijhawm tau teev tseg los ntawm cov neeg siv khoom. Ob tog tuaj yeem lees txais hnub xa khoom, lossis nws tuaj yeem lees paub hauv daim ntawv cog lus tom qab kev sib koom tes. Yog ua tau, cov kauj ruam tom ntej.

4. Kev yuav khoom ntawm cov khoom siv. Vim tias nws yog qhov kev pabcuam ib-nres rau PCBA, lub Hoobkas yuav tsum xav kom yuav cov khoom siv hluav taws xob. Tom qab daim ntawv cog lus tau kos npe, PCBA cov chaw cog khoom yuav yuav cov khoom raws li tus neeg siv khoom npe BOM.

5. Tuaj tshuaj xyuas. Raws li lub chaw tsim khoom tsim nyog PCBA, nws yog kev ua haujlwm niaj hnub los tshuaj xyuas thiab ntim cov khoom yuav. Vim tias tsuas yog cov khoom lag luam uas dhau qhov kev tshuaj xyuas zoo tuaj yeem siv hauv kev tsim khoom. Lwm qhov kev siv tshwj xeeb ntawm cov qauv kaw yog pab txhawb cov neeg siv khoom kom rov tshuaj xyuas cov ntaub ntawv uas cov neeg muag khoom yuav. (Tau kawg, qhov xwm txheej no zoo tshaj plaws kom tsis txhob tshwm sim. Yog tias ua tau, nws txhais tau tias muaj teeb meem ntau ntawm cov khoom lag luam cov khoom. Kev rov ua haujlwm yog qhov teeb meem tsis tseem ceeb, thiab nws yog qhov teeb meem loj kom tsis ntseeg cov neeg siv khoom).

6. PCBA theem tsim khoom. Tag nrho theem yog qhov txuas nrog cov txheej txheem feem ntau thiab kev tswj hwm cov txheej txheem hauv kev ua haujlwm. Cov kua nplaum sib xyaw ua ke, luam ntawv muab tshuaj txhuam, tshuaj xyuas cov tshuaj txhuam SPI, SMT thaj ua haujlwm, rov ua kom sov qhov cub qhov kub nkhaus teeb tsa, AOI kev tshuaj xyuas tag nrho, DIP plug-in wave soldering, thiab lwm yam.

7. PCBA xeem. Kev xeem yog qhov txuas uas yuav tsum tau ua tom qab PCBA kev tsim khoom tiav, suav nrog kev ua haujlwm, hlawv-hauv, ntsuas kev ua haujlwm thiab lwm yam. Tsuas yog tom qab dhau qhov kev xeem txuas los ntawm tus neeg siv khoom lag luam, cov khoom lag luam nrog PASS foob tuaj yeem nkag mus rau lub ntim txuas.

8. Ntim thiab thauj mus los. Tom qab Pcba kev xeem tsim khoom tiav, ntim khoom tuaj yeem nqa tawm tom qab mus txog tus neeg siv khoom tus qauv thiab kev pom zoo. Muaj cov ntim dav dav thiab ntim cov khoom tiv thaiv zoo li qub. Qhov no yuav tsum tau tshuaj xyuas raws li tus neeg siv khoom cov yam ntxwv khoom, thiab tom qab ntawd cov logistics txuas tuaj yeem siv tau.

Yeej, tom qab txheeb xyuas qhov sib txuas 8 saum toj no, peb tuaj yeem pom cov txuas uas peb xav tau los koom tes nrog lub tuam txhab thiab cov chaw muag khoom, thiab tom qab ntawd peb tuaj yeem npaj nrog xaiv cov PCBA tus neeg xa khoom tom qab peb nkag siab lawv.
