PCB los ua ke tus nqi, txhua tus kws tsim hluav taws xob lossis tus tsim qauv xav paub yuav ua li cas thiaj li tau txais cov lus hais zoo tshaj plaws rau PCB sib dhos thiab tus nqi cuam tshuam li cas rau PCB kev sib dhos tus nqi. Nov yog qee cov lus qhia yuav ua li cas tswj hwm tus nqi sib dhos PCB.

Ua ntej, nkag siab meej txog tus yam ntxwv ntawm PCB sib dhos (PCBA) cov nqi. Qee tus tsav tsheb them nqi loj tshaj suav nrog:

(1) Hom sib dhos Nto Mount (SMT) (SMD tivthaiv) Los ntawm qhov (DIP) sib tov (ob qho tib si)

(2) Kev sib koom ua ke tsuas yog thov ua ntu ntu sab saum toj kom thov Doulbe ob tog sib dhos

(3) Tag nrho cov khoom siv (SMD + DIP)

(4) Cheebtsam pob khoom loj 1206 0804 0603 0402 020101005

(5) Ntim ntim khoom (reel qhov tseem ceeb) Reel yeeb nkab tais txoj siv lossis txiav kab xev ntim lub hnab ntim tsis muaj txoj siv lead ua

(6) SMT SMT los ntawm qhov tsis siv neeg nkag mus los ntawm lub qhov zawv zawg kab yoj siv lub tshuab ntsuas qhov muag pom tsis siv neeg (AOI); br> ua X -ray xaiv cov laug siv phau ntawv qhia ua ke

(7) Qhov ntau thiab tsawg me me

“Khaws Panelize hloov pauv kom tau raws li koj lub khw xav tau.”

Koj yuav tsum ua kom ntseeg tau tias kev ua kom zoo tau zoo rau qhov xav tau ntawm PCBA cov tuam txhab tsim khoom.

(8) Kev npaj tshwj xeeb rau qhov tshwj xeeb (piv txwv li, txhuas lub sijhawm, qhov tsawg kawg/qhov siab tshaj plaws, sib nrug)

(9) Tag nrho tus nqi ntawm ua kom tiav Cov Nqi Khoom Siv (BOM)

(10) Tus naj npawb ntawm cov laug cam (PCB) txheej thiab cov khoom siv

Cov khoom siv PCB yooj ywm raug nqi ntau dua li cov laug cam PCB

(11) Cov txheej txheem txheej txheej (kev kho mob lossis tub rog feem ntau xav tau txheej txheej lossis xaiv txheej) Txau lossis txhuam txheej Tus naj npawb ntawm txheej – Txheej siab kam rau ua tshwj xeeb txheej txheej

(12) Kev xav tau rau kev cog qoob loo (yog tias muaj)

(13) Kev ua raws li kev cai ua raws RoHS (tsis muaj lead) Tsis-ROHS (coj) IPC-A-610D Hoob I, Hoob II lossis Chav III ITAR

(14) Kev xeem yuav tsum tau (RayMing xav sim txhua PCBA cov laug cam ua ntej xa zaub mov, peb xav kom koj qhia peb yuav ntsuas li cas) Lub zog-ua haujlwm ntsuas Circuit (ICT) Kev caij tsheb kauj vab tsis muaj kev sim (kuaj pom nkaus xwb)

(15) Thauj khoom xav tau tus qauv ESD (tso tawm electrostatic) hnab tsis yog tus qauv/ntim tshwj xeeb

(16) Kev xa khoom (RayMing muab kev pabcuam PCB sib dhos nrawm)

Kev tswj tus qauv, tsis muaj kev thov maj nrawm hloov pauv sai (kev ua haujlwm thiab cov khoom raug cuam tshuam)

Qhov 16 cov lus qhia no yuav cuam tshuam tus nqi ntawm PCB sib dhos, yog li koj tuaj yeem xaiv qhov zoo tshaj plaws kom txuag tau tus nqi, thaum koj yuav khoom, koj tuaj yeem muab cov khoom siv ntau yam rau txhua feem, nws yooj yim los tswj qee tus nqi, tsis yog los ntawm digikey, qee tus neeg sawv cev tseem muaj tus nqi muaj zog txhawb nqa ib feem, nrawm dua kom txo tus nqi

Teeb tsa tus txheej txheem kom tau txais cov peev txheej qis hauv nruab nrab ntawm koj li kev tsim qauv engineering thiab cov tuam txhab yuav khoom. Qhov no yooj yim dua hais dua li ua tiav. Kev tsis sib haum xeeb ua ntej ntawm kev tsim qauv engineering thiab kev yuav khoom tuaj yeem cuam tshuam cov txheej txheem no.

Ib qho kev daws teeb meem yog teeb tsa pawg neeg txo nqi. Kev tswj hwm ua haujlwm nrog kev yuav khoom thiab kev tsim vaj tsev txhawm rau txheeb xyuas txoj hauv kev txo tus nqi muaj txiaj ntsig. Lawv kuj tseem ua haujlwm txhawm rau txheeb xyuas cov txheej txheem txheej txheem uas xav tau ntau qhov chaw los ua kom muaj kev tsim khoom txuas ntxiv mus.
