Cov PCBa cov txheej txheem ntau lawm tuaj yeem muab faib ua ntau cov txheej txheem tseem ceeb:

PCB tsim thiab kev txhim kho → Bood Patch Ua → DIPll-hauv kev → Peb cov khoom ua tiav → Cov Khoom Ua tiav.

Ua ntej, PCB tsim thiab kev loj hlob

1.Product kev thov

Ib qho phiaj xwm tuaj yeem tau txais qee yam txiaj ntsig zoo hauv kev ua lag luam tam sim no, lossis cov kev txhawb nqa tau xav ua kom tiav lawv tus kheej DIY tsim, tom qab ntawd cov khoom lag luam zoo yuav tsim tau;

2. Tsim thiab Kev Loj Hlob

Ua ke nrog cov neeg siv khoom lag luam xav tau, R & D DEC cov encuitys yuav xaiv cov tshuaj thiab sab nraud yuav tsum tau ua tiav cov khoom lag luam thiab cov ntsiab lus tseem ceeb, cov ntsiab lus koom nrog ntawm no yuav tau piav qhia sib cais;

3, Qauv Qauv Sib Tw

Tom qab txoj kev txhim kho thiab tsim qauv ntawm cov khoom siv ua ntej, tus neeg yuav khoom siv los ntawm cov ntaub ntawv pov thawj raws li cov khoom lag luam (50pcs), thiab tom qab ntawd yuav nkag mus rau ntau lawm Theem.

Thib ob, SMT Patch Ua

Cov txheej txheem ntawm SMT Patch Ua rau: Cov Khoom Siv Ci → Solding Paste nkag → Mounting → Refowing Soldering → Khoos → Kho

1. Cov ntaub ntawv ci

Rau tej daim, PCB cov laug cam, cov ntaub ntawv qauv thiab cov ntaub ntawv tshwj xeeb uas tau nyob hauv Tshuag rau ntau tshaj 3 lub hlis, lawv yuav tsum tau ci ntawm 120 ℃ 24h. Rau MOLICOHRE, LED teeb thiab lwm yam khoom uas tsis tiv taus qhov siab kub, lawv yuav tsum ci ntawm 60 ℃ 24h.

2, SOLDER muab tshuaj txhuam (rov qab kub → storring → siv)

Vim tias peb ham muab tshuaj muab tso rau hauv ib puag ncig ntawm 2 ~ 10 ℃ rau lub sijhawm ntev, nws yuav tsum tau rov qab mus rau qhov ntsuas kub, nws yuav tsum tau luam tawm nrog rab phom, thiab tom qab ntawd nws tuaj yeem luam tawm.

3. Spi3D nrhiav tau

Tom qab sold muab muab luam tawm yog luam tawm ntawm Circuit Courner, tus PCB yuav mus txog ntawm cov khoom siv hluav taws xob, thiab SPI, ntev ntev ntawm cov ham muab luam tawm thiab cov xwm txheej zoo ntawm cov npoo npoo.

4. Mount

Tom qab pcb ntws mus rau SMT TSHUAB, lub tshuab yuav xaiv cov khoom tsim nyog thiab muab tshuaj txhuam rau tus lej sib xws los ntawm cov teeb meem teeb tsa;

5. Reflow Vuam

Tus PCB muaj cov khoom ntws mus rau sab xub ntiag

6, online auoi kuaj

AOI yog qhov ntsuas hluav taws xob tsis siv neeg, uas tuaj yeem tshawb xyuas cov PCB pawg thawj coj tawm los ntawm cov khoom sib txuas ntawm PCB, seb puas muaj cov khoom sib txuas ntawm cov khoom siv PCB, txawm hais tias cov khoom siv sib txuas los ntawm cov khoom siv ntawm PCB, puas tuaj yeem tshawb xyuas cov khoom sib txuas ntawm tus kheej, puas tuaj yeem txuas nrog cov khoom siv ntawm tus lej PCB, seb puas muaj cov khoom sib koom ua ke ntawm cov khoom siv

7. Kho

Rau cov teeb meem uas pom nyob rau ntawm PCB pawg thawj coj hauv Aoi lossis tus kheej, nws yuav tsum tau kho los ntawm tus saib xyuas kev tu, thiab kho PCB Board pawg yuav raug xa mus ua ke nrog cov chaw pib offline.

Peb, dip plug-in

Cov txheej txheem ntawm DIP plug-nyob rau hauv tau muab faib ua: share → strow schering → Tuav Tin → Kev Soj Ntsuam Zoo

1. Yas phais

Cov khoom siv cov khoom siv uas peb tau yuav yog txhua cov ntaub ntawv ntawm cov khoom siv, yog li peb yuav tsum tau kho cov taw sib txawv, yog li cov txhais taw yooj yim rau peb kom nqa tawm ntawm cov ntsaws ruaj khov lossis ncej vuam.

2. Plug-in

Cov txheej txheem ua tiav yuav raug muab tso rau raws li cov qauv sib xws;

3, yoj soldering

Cov phaj ntxig tau muab tso rau ntawm jig rau pem hauv ntej ntawm nthwv dej soldering. Ua ntej, Flux yuav muab tshuaj tsuag rau hauv qab los pab vuam vuam. Thaum lub phaj tuaj rau sab saum toj ntawm lub hwj cua sov, cov dej tin nyob rau hauv lub cub hluav taws yuav ntab thiab hu rau tus lej PIN.

4. Txiav tus taw

Vim tias cov ntaub ntawv ua ntej ua ntej yuav muaj qee yam cai tshwj xeeb los teeb tsa nws tus kheej ntev dua, tus lej PIN yuav txiav txim siab rau kev txiav txim siab los ntawm phau ntawv trimming;

5. Tuav Tin

Tej zaum yuav muaj qee qhov tshwm sim tsis zoo xws li qhov, pinholes, tsis muaj vuam, cuav vuam, cuav vuam thiab li ntawm pins ntawm peb lub pcb board tom qab taws. Peb Tin tus tuav yuav kho lawv los ntawm phau ntawv kho.

6. Ntxuav lub rooj tsavxwm

Tom qab yoj soldering, kho thiab lwm qhov txuas pem hauv ntej, yuav tsum muaj qee cov khoom lag luam pcb uas xav tau rau tus pcb board, uas xav kom peb cov neeg ua haujlwm los ntxuav nws cov npoo;

7. Kev Soj Ntsuam Zoo

PCB Board Cheebtsam yuam kev thiab cov kab mob tokage, tsis tsim nyog pcb board yuav tsum tau kho, kom txog thaum tsim nyog tau txais kauj ruam tom ntej;

4. PCBA xeem

PCBA kuaj tuaj yeem faib ua ICT xeem, xeem ntawv, kev sim siab, kev co, thiab lwm yam

PCBA xeem yog qhov kev ntsuas loj, raws li cov khoom sib txawv, cov neeg siv khoom sib txawv, cov kev xeem txhais tau tias siv sib txawv. ICT Kev kuaj mob yog txhawm rau txhawm rau txhawm rau qhov mob vuam thiab cov kab mob ntawm FCT yog txhawm rau txhawm rau tshawb xyuas cov thawj coj PCBA seb lawv yuav ua li cas.

Tsib: PCBA peb los tiv thaiv txheej

PCBA peb los tiv thaiv txheej txheem txheej txheem yog: txhuam sab ib → saum npoo qhuav → txhuam sab ntawm 5. Txau tuab:

0.1mm-0.3mm6. Txhua txheej txheej ua haujlwm yuav tsum tau nqa tawm ntawm qhov kub tsis qis dua 16 ℃ thiab txheeb ze cov av noo hauv qab 75%. PCBA peb los tiv thaiv ntau yog ntau yam, tshwj xeeb tshaj yog qee qhov kub thiab av noo, tuaj yeem tiv thaiv kev ua kom zoo dua, tuaj yeem tiv thaiv cov yaig sab nraud, kev ua qias tuaj thiab lwm yam. Txau txoj kev yog qhov feem ntau siv txheej txheej hauv kev lag luam.

Cov Khoom tiav Los Ua Ke

7.Qhov coated pcba board nrog kev sim OK yog sib sau ua ke rau lub plhaub, thiab tom qab ntawd tag nrho cov khoom lag luam tsis muaj teeb meem los ntawm kev xeem ua haujlwm tuaj yeem xa tawm.

PCBA ntau lawm yog qhov txuas rau qhov txuas. Txhua qhov teeb meem hauv PCBA cov txheej txheem ntau lawm yuav muaj kev cuam tshuam zoo rau cov khoom zoo tag nrho, thiab txhua tus txheej txheem yuav tsum tau tswj hwm nruj.
