Nws tshwm sim ntau zaus uas peb nyiam IC tsuas muaj nyob hauv pob SMD thiab tsis muaj txoj hauv kev los sim nws tawm ntawm lub khob cij. Yog li hauv cov lus qhia luv luv no kuv yuav qhia koj txoj kev uas kuv tau ua kuv tus kheej lub khoos phis tawj me me rau SMD IC xws li Nws tuaj yeem siv tau yooj yim los ntsuas koj lub Circuit Court ntawm lub khob cij thiab txawm tias nws muab lo rau ntawm lub qhov txhab.

Nco tseg: Cov laug cam tawg ntawd muaj nyob hauv kev ua lag luam nrog kev ua haujlwm PCB tab sis qhov no tsuas yog txoj hauv kev nrawm thiab yooj yim kom tau txais qhov txiaj ntsig zoo ib yam uas kuv tau sim thiab ua haujlwm zoo rau kuv lub Circuit Court thiab kuv xav qhia nws rau koj txhua tus. Nws muaj peev xwm ua tiav los tsim PCB rau kev tsim thiab siv nws.

Kauj Ruam 1: Sib Sau Cov Khoom

Txoj haujlwm no tsis xav tau ntau qhov chaw raws li peb npaj siab yuav ua tus pin txuas ntxiv rau SMD IC

Koj yuav xav tau cov hauv qab no:

• Me me ntawm tooj liab clad board txiav kom haum
• Txiv neej lub taub hau (Rau 8 tus pin IC koj yuav xav tau ib khub ntawm 4 tus pin txiv neej lub taub hau)
• Luam tawm ntawm txheej txheej ntawm IC thiab kab ntawv taub hau
• Cov cim ruaj khov
• Ferric chloride tov rau etching tooj liab
• Cov khoom siv Soldering
• Isopropyl cawv los ntxuav qhov chaw

Kauj Ruam 2: Luam tawm ntawm Circuit

Kuv xub tsim cov txheej txheem ntawm PCB tsim software (Kuv tau siv Esy EDA ntawm no tab sis koj tuaj yeem siv lwm yam software uas koj xaiv) khaws IC hauv nruab nrab thiab 4 tus pin txiv neej lub taub hau tau nyob ntawm txhua sab ib yam li pob DIP. Qhov nrug nruab nrab ntawm ob tus txiv neej header pins yog 13mm uas yog qhov loj dua li ib txwm 7.62 mm nrug nruab nrab ntawm ob tus lej sib txawv ntawm DIP IC, qhov laj thawj yog qhov tsis muaj chaw nyob.

Kuv kuj tseem tau txuas daim PDF ntawm kev teeb tsa uas yog qhov ntsuas rau siv.

Kauj Ruam 3: Ua Kos Npe rau ntawm Rooj Tswjhwm Saib Tooj

Kuv tau xuas nrig hauv qhov tsim nyog qhov kawg ntawm qhov luam tawm siv lub koob ntsuas ntawm qhov chaw uas tus pin header yuav haum thiab tseem pinched qhov rau tus pin ntawm IC. Tom qab ntawd kuv tau siv qee daim kab xev los lo rau daim ntawv luam tawm rau ntawm lub rooj tsav tooj liab thiab cim cov ntsiab lus los ntawm cov hneev taw mus rau lub rooj tsav tooj liab.

NCO TSEG: Koj tuaj yeem yooj yim yog li cov kauj ruam no siv lub tshuab luam ntawv hloov pauv yog tias koj muaj lub tshuab luam ntawv laser thiab ntawv ci hauv tsev. Kuv tsuas yog sim ua nws nrog txhua yam uas kuv muaj hauv kuv lub tsev, thiab kuv tsis muaj lub tshuab luam ntawv laser yog li kuv tau mus ua ntej txhawm rau ua cov cim nrog tus cim ruaj khov.

Kauj Ruam 4: Kev Tso Npe Ntawm Cheeb Tsam

Cov duab hauv qab no qhia yuav ua li cas IC thiab lub taub hau yuav raug muab tso rau hauv tus qauv

Kauj Ruam 5: Tshem Tawm Cov Tooj Liab Tshaj Tawm ntawm Pawg Thawj Coj

Tam sim no yog lub sijhawm los txhawm rau tshem cov tooj liab ntau dhau los ntawm lub rooj tsavxwm thiab tawm hauv qab tsuas yog cov cim hauv qab tus cim. Rau etching Kuv tau siv cov tshuaj ferric chloride tov rau hauv lub thawv me me thiab khaws cov tooj liab tooj liab hauv kev daws teeb meem li 10-15 feeb nrog qee zaum nplawm los xyuas kom zoo ib yam

NCO TSEG: ua tib zoo ceev faj thaum siv tshuaj lom tshuaj thiab siv hnab looj tes tiv thaiv kev nyab xeeb vim tias cov tshuaj ferric chloride tuaj yeem tawm cov cim tsis zoo ntawm daim tawv nqaij thiab ntaub thiab tuaj yeem ua rau tawv nqaij tawv.

Kauj Ruam 6: Ua tiav! … Zoo, Ib yam ntawm

Yog li qhov no li cas PCB tau dhau los ua thiab thaum cov ntaub qhwv rau lub taub hau cam tawm zoo nkauj, cov cim tsis tau dhau ntawm qhov cim. Tom qab ntawv ntxiv, Kuv tau ua nws nrog tus cim thiab tsis muaj ntau yam tuaj yeem xav tawm ntawm nws. Yog tias koj tab tom siv cov txheej txheem hloov pauv toner cov txiaj ntsig yuav muaj txiaj ntsig zoo.

Txawm li cas los xij, Kuv tau txiav txim siab tin rau tag nrho cov kab ke txhawm rau txhawm rau txhawm rau qhov ua tsis tiav.

Kauj Ruam 7: Tinning Traces thiab Ntxiv Headers

Tom qab tinning cov kab thiab soldering tus txiv neej header pins, tam sim no kev sib txuas tau zoo ib yam yam tsis muaj kev txiav tawm. Siv cov lus qhia ntxaws zoo txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau thiab siv cov dej ntws kom cov txheej txheem tinning zoo ib yam.

Kauj Ruam 8: Soldering IC hauv Qhov Chaw

Nov yog qhov kawg module zoo li tom qab soldering IC hauv qhov chaw. Ib qho kev saib xyuas yuav tsum tau ua kom tsis txhob muaj qhov luv ntawm cov kab vim yog cov laug ntau dhau, ua kom ntseeg tau tias cov kab ke muaj kev tshem tawm zoo.

Tom qab ntxuav lub rooj tsavxwm nrog qee cov cawv isopropyl, Kuv ua cov kab hauv kaum ntawm IC nrog tus cim ruaj khov kom thiaj li tau txais lub tswv yim ntawm kev taw qhia.of IC

Kauj Ruam 9: Qhov Kawg

Tus qauv haum zoo rau ntawm daim ntawv tais thiab tam sim no tuaj yeem siv los ntsuas tawm cov kab hluav taws xob Kuv xav ua nrog IC no

Kuv vam tias qhov kev qhia me me no tau muab tswv yim rau koj siv SMD IC rau kev sim lub hom phiaj

Tsis txhob hnov qab saib cov vis dis aus hauv cov kauj ruam tom ntej rau cov ncauj lus kom ntxaws txheej txheem thiab thaum koj nyob ntawd, sau npe yuav ua rau kuv cov channel rau ntau cov ntsiab lus zoo li no thiab DIY tswv yim. Ua tsaug:)
