Yuav Ua Li Cas Kom Neatly Solder (tsis muaj Loads ntawm Cov Xov!) Decoupling Caps ntawm SMT Microcontrollers

Cov lus qhia no tau sau los qhia koj yuav siv li cas thiab ua kom zoo ntawm kev tsim qauv nrog SMT microcontrollers (lossis lwm yam khoom siv) ntawm lub rooj hloov khoom siv.

Tom qab tawm tsam txhawm rau ua txoj haujlwm kom zoo ntawm kev txiav tawm lub zog ntawm kuv lub PIC18F Kuv txiav txim siab qee yam uas yuav tsum tau ua! Cov ntawv qhia no qhia kuv ua dab tsi….. Qhov no yog kuv thawj qhov kev qhia (Kuv xav tias nws yog lub sijhawm los muab qee yam rov qab!) (sib nrug los ntawm cov hlawv hlawv!) tsis nws…. nyeem rau!

Kauj ruam 1: Pib Pib…

Cia peb pib…
Cia peb pib…

Thawj kauj ruam yog txhawm rau txuas koj lub cuab yeej mus rau lub rooj hloov pauv raws li tuaj yeem pom hauv daim duab hauv qab no.

Kuv pom tias txoj hauv kev zoo tshaj plaws los txhuam cov khoom zoo (ish) cov cuab yeej siv yog siv cov dej ntws zoo thiab qee qhov ua cov laug (tsis txhob qhia ib puag ncig txawm tias;-)!).

Kauj Ruam 2: Daim Kab Xev tooj liab thiab Capacitor Lead Forming

Ua ntej koj yuav tsum txiav ib daim ~ 20mm x ~ 20mm daim kab xev tooj liab thiab lo nws mus rau hauv nruab nrab ntawm sab hauv qab ntawm lub adapter board.

Tom ntej no koj xav tau txhawm rau txhawm rau txhais ceg ntawm lub rooj hloov pauv nrog ib lub tshuab hluav taws xob tso rau hauv los ntawm cov khoom lag luam zoo (kom txiav tawm) qhov thiab lwm ceg tso los ntawm kev txuas hauv av. Qhov no yooj yim haum nrog PIC18F txij li lub zog thiab kev sib txuas hauv av feem ntau nyob ze ua ke. Tom ntej no koj yuav tsum tau muab cov kab me me ntawm cov tub ntxhais hlau xaim rau hauv av hauv ob txhais ceg raws li qhia hauv cov duab hauv qab no. Cov xaim no yuav tsum tau tsim xws li lawv sib tshooj daim kab xev tooj liab nyob hauv nruab nrab. Daim kab xev tooj liab no yuav dhau los ua peb lub dav hlau hauv av.

Kauj Ruam 3: Soldering Decoupling Capacitors

Thaum koj tau tsim cov hlau tseem ceeb hlau hla daim kab xev tooj liab koj yuav tsum tau ua tib zoo xaim cov xaim rau daim kab xev. Qhov no yog qhov ua tau zoo tshaj plaws sai thiab nrog cov tshuaj txhuam tsawg.

Cov duab hauv qab no qhia txog kev sib txuas.

Kauj Ruam 4: Rho Tawm Lub Dav Hlau Tsis Zoo

Cov kauj ruam tom ntej yog los daws qhov kev sib txuas zoo.

Ua ntej koj yuav tsum tau insulate daim kab xev tooj liab uas twb muaj lawm 'hauv av dav hlau' nrog qee daim kab xev. Kuv siv Sellotape tab sis kuv paub tseeb tias muaj qee yam zoo dua! Tej zaum Kapton daim kab xev? Nco ntsoov tias hauv av tau zoo insulated thiab tom qab ntawd txav mus. Tom ntej no koj yuav tsum lo lwm daim me me zoo ib yam ntawm daim kab xev tooj liab hla lub dav hlau hauv av. Cov duab hauv qab no qhia txog lub dav hlau av insulated nrog Sellotape.

Kauj Ruam 5: Ntxiv Lub Dav Hlau Zoo

Thaum koj zoo siab tias lub dav hlau hauv av tau tiv thaiv zoo koj yuav tsum lo daim kab xev tooj liab thib ob rau nws raws li qhia hauv cov duab hauv qab no.

Nco ntsoov tias koj tau txais daim kab xev tooj liab zoo kaw!

Kauj Ruam 6: Ntau Tus Capacitor Lead Forming

Ntau Lub Capacitor Lead Forming!
Ntau Lub Capacitor Lead Forming!
Ntau Lub Capacitor Lead Forming!
Ntau Lub Capacitor Lead Forming!

Tom ntej no koj yuav tsum tau siv qee qhov ntxiv ib qho cored hlau thiab txuas ib qho kawg rau sab zoo ntawm qhov txiav tawm lub tshuab hluav taws xob thiab lwm qhov yuav tsum tau tsim xws li nws hla daim kab xev tooj liab. Daim kab xev tooj liab no yog los ua peb lub dav hlau muaj hwj chim zoo.

Saib cov duab hauv qab no rau lub tswv yim ntawm yuav ua li cas nws yuav tsum saib!

Kauj Ruam 7: Me ntsis Soldering

Me ntsis Ntxiv Soldering
Me ntsis Ntxiv Soldering

Tam sim no koj yuav tsum tau txuas cov kev sib txuas zoo no.

Ib zaug ntxiv, xyuas kom tseeb tias koj ua haujlwm zoo ntawm cov laug thiab tsis txhob siv cov laug ntau dhau. Yog koj saib ze koj tuaj yeem pom Sellotape tsuas yog poking tawm ntawm ntug ntawm daim kab xev tooj liab. Saib cov duab hauv qab no:-)

Kauj Ruam 8: Txuas Cov Khoom Siv Hluav Taws Xob

Txuas Cov Khoom Siv Hluav Taws Xob
Txuas Cov Khoom Siv Hluav Taws Xob

Tom ntej no koj yuav tsum tau siv qee lub xov tooj liab thiab dub thiab muab cov dub txuas rau hauv av txuas rau sab saum toj ntawm lub rooj sib txuas thiab lub liab rau ib qho kev sib txuas zoo nyob ib sab.

Saib daim duab hauv qab no kom paub meej.

Kauj Ruam 9: Ua Kom Paub tseeb tias Koj Tsis Tau Tshaj Tawm Txhua Yam Tawm:-)

Ua kom ntseeg tau tias koj tseem tsis tau luv tag nrho qhov tawm:-)
Ua kom ntseeg tau tias koj tseem tsis tau luv tag nrho qhov tawm:-)

Tom ntej no koj yuav tsum siv DMM (Digital Multi Meter) kom paub tseeb tias koj tsis tau luv luv hauv av txuas mus rau kev sib txuas zoo. Yog tias lawv luv koj nyob hauv teeb meem loj vim tias txoj kev txuas no (nrog daim kab xev thiab lwm yam) tsis yooj yim rov ua haujlwm tau! DMM (teeb tsa rau Ohms ntsuas) yuav tsum qhib qhib ntawm cov xov tooj liab thiab dub yog tias txhua qhov txuas nrog raug. duab hauv qab no qhia seb pawg thawj coj ua haujlwm yuav tsum qhia dab tsi ntawm DMM. Thaum nws ua haujlwm koj muaj lub rooj zoo, rov siv tau tau tsim nyog rau kev tsim qauv thiab qhia tawm rau tib neeg yam tsis muaj cov xov hlau txuas thiab lwm yam. thiab yuav qhia qee qhov txiaj ntsig ntawm kev siv av thiab lub zog dav hlau txawm hais tias lub peev xwm ntawm ob lub tooj liab 'phaj' zoo li tsuas yog ob peb nF (nano-Farads) zoo tshaj yog tias koj nyiam qhov kev qhia no thiab muaj kev txaus siab rau khoom siv hluav taws xob thov hla mus rau PCBPolice thiab hais nyob zoo:-) Ua tsaug ntau, S.
