Vim li cas BOM Sourcing Matters Ua Ntej PCBA Ntau Lawm
BOM yog ib qho yooj yim rau underestimate. Nyob rau saum npoo, nws tsuas yog ib daim ntawv teev npe. Hauv qhov project PCBA tiag tiag, nws yog qhov tsim qauv tsim, kev pheej hmoo ntawm kev tsim khoom, tus nqi, lub sijhawm ua haujlwm, thiab kev npaj sib dhos tag nrho.
Ntau qhov kev ncua tsis pib ntawm SMT kab. Lawv pib ua ntej, thaum tus naj npawb ib feem tsis tiav, ib pob ntawv tsis sib haum nrog cov hneev taw, lub connector muaj lub sij hawm ntev, los yog qhov hloov pauv tsis tau pom zoo. Thaum lub sij hawm cov teeb meem no tshwm sim thaum lub sij hawm yuav khoom los yog npaj cov khoom, lub sij hawm twb nyob rau hauv lub siab.
Ntawm STHL, BOM qhov chaw yog ib feem ntawm pebCheebtsam Sourcingkev ua haujlwm. Peb tshuaj xyuas PCB sib dhos BOM raws li cov ntaub ntawv tsim khoom, tsis yog daim ntawv yuav khoom xwb. Lub hom phiaj yog yooj yim: nrhiav cov khoom txaus ntshai ua ntej lawv tig mus rau hauv kev sib dhos qeeb.
BOM kev muab khoom txhais li cas hauv PCBA lossis EMS qhov project?
BOM cov khoom siv txhais tau tias kuaj xyuas, muab khoom, thiab npaj cov khoom uas tau teev tseg hauv cov neeg siv khoom cov ntaub ntawv ua ntej PCBA pib.
Qhov ntawd suab ncaj nraim, tab sis hauv kev xyaum BOM kov ob peb pab pawg:
- Engineering xyuas seb cov khoom xaiv puas haum rau kev tsim qauv.
- Kev txheeb xyuas cov khoom muaj, MOQ, MPQ, kev xaiv tus neeg muag khoom, thiab lub sijhawm ua haujlwm.
- Kev npaj ntau lawm xyuas seb cov khoom puas tuaj yeem npaj ua ntej sib dhos.
- Kev kuaj xyuas zoo seb puas muaj cov ntaub ntawv txaus rau kev tshuaj xyuas thiab kev taug qab.
- Tus neeg yuav khoom xav tau kev pom tseeb ntawm tus nqi, lub sijhawm, thiab kev pheej hmoo ntawm qhov khoom.
BOM tuaj yeem saib huv thiab tseem ua rau muaj teeb meem. Ib qho chaw tsim khoom uas ploj lawm, ib pob tsis meej, IC dhau los, lossis lwm qhov tsis pom zoo tuaj yeem ua rau tag nrho cov tsim. Qhov no yog vim li cas BOM nrhiav yuav tsum tshwm sim ua ntej kev yuav khoom pib, tsis yog tom qab lub sijhawm tsim khoom tau raug kho.
Ib qho kev txiav txim siab ntawm no: yog BOM tsuas yog hais tias "10k resistor" yam tsis muaj pob, kam rau ua, qhov ntsuas hluav taws xob, thiab cov ntsiab lus siv tus qauv tsim, nws tsis npaj rau PCBA nrhiav. Tej zaum nws yuav txaus rau kev sib tham tsim thaum ntxov, tab sis tsis txaus rau kev yuav khoom lag luam.
Dab tsi yuav tsum tau kuaj ua ntej BOM kev yuav khoom?
Cov txheej txheem kev txhim khu kev qha pib nrog BOM tshuaj xyuas thiab BOM pov thawj.
Ua ntej BOM kev yuav khoom pib, STHL tshawb xyuas BOM tiv thaiv cov ntaub ntawv muaj nyob hauv qhov project, xws li Gerber cov ntaub ntawv, kos duab sib dhos, xaiv - thiab - qhov chaw cov ntaub ntawv / CPL, PCB specifications, thiab cov khoom yuav tsum tau ua.
Cov khoom kuaj BOM ib txwm muaj xws li:
- Chaw tsim tshuaj paus tus lej raug
- Lub npe chaw tsim khoom thiab cov neeg muag khoom pom zoo yuav tsum tau ua
- Pob thiab hneev taw sib xws

- Reference tus tsim clarity
- Cov khoom muaj nqis, kam rau ua, voltage, tam sim no, thiab ntsuas
- Cov xwm txheej ntawm lub neej, suav nrog kev siv tsis tau lossis xaus - ntawm - lub neej
- RoHS, REACH, lossis qhov project -cov kev xav tau tshwj xeeb ua raws
- Moisture rhiab heev los yog tshwj xeeb tuav yuav tsum
- Hloov cov kev txwv thiab kev pom zoo rau cov neeg siv khoom
Cov ntsiab lus me me tseem ceeb. Lub pob resistor tsis sib haum yuav tsis zoo thaum hais lus, tab sis nws tuaj yeem tso tseg tom qab. Ib qho txuas nrog qhov tsis ncaj ncees lawm kev taw qhia tuaj yeem dhau los ntawm kev yuav khoom thiab tsuas yog ua kom pom tseeb thaum kuaj xyuas cov khoom sib dhos. Cov no yog cov teeb meem uas tsim nyog BOM tshuaj xyuas yuav tsum tau txais ntxov.
Cov kauj ruam no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau turnkey PCBA thiab ib feem ntawm turnkey tej yaam num, qhov chaw muab khoom thiab sib dhos yog ib feem ntawm tib lub workflow.
Puas yog BOM kev muab khoom ib yam li BOM kev yuav khoom?
Tsis raws nraim.
BOM cov khoom siv los ua ntej. Nws tsom mus rau kev kuaj xyuas muaj, tshuaj xyuas kev pheej hmoo, kev xaiv tus neeg muag khoom, thiab lwm txoj hauv kev ua ntej yuav khoom. BOM kev yuav khoom pib tom qab paub tseeb tias qhov kev npaj yuav khoom. Nws yog hais txog kev yuav khoom ua tiav, lub sijhawm ua raws li- nce, kev taug qab cov khoom, thiab kev npaj tuaj.
Rau PCBA thiab EMS cov haujlwm, STHL txuas ob theem nrog cov kev xav tau tiag tiag:
- BOM nrhiav qhov muaj thiab kev pheej hmoo kuaj xyuas
- BOM kev yuav khoom rau cov ntaub ntawv pom zoo
- Kev sib koom ua lag luam raws li qhov xav tau ntawm qhov project
- Lub sijhawm tshuaj xyuas rau qhov tseem ceeb
- Kev npaj cov khoom ua ntej IQC
- Kev sib koom tes nrog PCB los ua ke, kuaj, thiab lub thawv tsim lub sijhawm
Qhov sib txawv tseem ceeb vim tias kev yuav khoom yam tsis tau kuaj xyuas seb lawv yuav sib sau ua ke yog ib qho ntawm cov khoom pov tseg. Ib qho kev txiav txim siab uas zoo nkaus li zoo ntawm tus nqi kuj tseem yog qhov tsis ncaj ncees rau kev tsim yog tias lub ntim, lub sijhawm ua haujlwm, lossis kev pom zoo tsis haum rau qhov project.
Lub sij hawm ua cov sij hawm ntev npaum li cas cuam tshuam rau PCBA cov sij hawm?
Hauv ntau qhov haujlwm PCBA, lub sijhawm tsim khoom tsis txwv los ntawm SMT peev xwm. Nws yog txwv los ntawm cov khoom siv nrog lub sijhawm ua haujlwm ntev tshaj plaws.
Lub sijhawm ua haujlwm ntev ntev yuav suav nrog MCUs, ICs tswj fais fab, cov khoom sib txuas, sensors, kev sib txuas lus modules, industrial-qib chips, lossis lwm qhov chaw uas muaj tsawg. Yog tias cov khoom no pom tau lig dhau lawm, lawv tuaj yeem ncua kev tsim qauv, kev tsav tsheb khiav, lossis kev txiav txim ntau lawm.
Thaum lub sij hawm BOM nrhiav, STHL tshuaj xyuas cov sij hawm ntev ua ntej. Thaum muaj kev pheej hmoo tshwm sim, peb tuaj yeem sib tham txog cov kev xaiv tswv yim xws li:
- Tshawb xyuas cov chaw muag khoom muaj
- Kev tshuaj xyuas cov neeg siv khoom- pom zoo lwm txoj hauv kev
- Sib cais qhov tseem ceeb ntev - cov khoom coj los ntawm cov khoom sib xws
- Txhawb nqa cov txheej txheem rau kev tsim qauv thiab tsim khoom xav tau
- Txhim kho cov khoom npaj nrog PCBA lub sijhawm sib dhos
Muaj ib qho xwm txheej uas tsim nyog hais meej meej: STHL tsis hloov cov khoom tsis muaj kev pom zoo rau cov neeg siv khoom. Lwm qhov chaw yuav zoo li zoo sib xws hauv kev tshawb nrhiav tus neeg muag khoom, tab sis qhov ntawd tsis ua rau lawv tau txais. Kev ua tau zoo ntawm hluav taws xob, pob khoom, lub neej voj voog, kev ua raws cai, kev coj tus cwj pwm firmware, thiab kawg - siv cov kev cai yuav tsum muaj teeb meem.
Rau kev lag luam thiab ntev -cov khoom siv hauv lub neej, kev hloov "ze txaus" tuaj yeem yog qhov yuam kev kim heev.
BOM optimization puas tuaj yeem txo tus nqi yam tsis muaj kev pheej hmoo ntxiv?
Qee zaum, yog. Tab sis BOM optimization yuav tsum tsis txhob txhais hais tias yuav cov khoom pheej yig tshaj plaws.
Hauv kev tsim PCBA, tus nqi qis dua tuaj yeem dhau los ua tus nqi yog tias nws tsim cov teeb meem kev sib dhos, kev tsis txaus ntseeg, kev hloov pauv engineering, lossis teeb meem kev ntseeg siab. Kev txo nqi BOM zoo yog feem ntau tho txawv thiab siv tau. Nws saib ntawm qhov muaj, pom zoo lwm txoj hauv kev, MOQ, ntim, qauv, thiab kev ruaj ntseg ntawm lub neej.
Cov txheej txheem ua kom zoo BOM ua tau zoo yuav suav nrog:
- Txheeb xyuas cov khoom siv nrog cov khoom tsis ruaj khov
