Muaj ob hom tseem ceeb ntawm cov khoom sib koom ua ke uas peb yuav mus hla hauv phau ntawv qhia "Yuav Siv Li Cas", axial-leaded dhau los ntawm lub qhov thiab ob kab hauv kab (DIP's). Yog tias koj tau ua me ntsis ntawm kev ua zaub mov noj, tej zaum koj twb tau paub nrog cov neeg tawm tsam ua tawm tsam thiab DIP IC's. Phau ntawv qhia no yuav muaj txiaj ntsig zoo hauv kev coj koj cov phiaj xwm tsim los ntawm daim phiaj rau lub rooj tsav xwm hauv Circuit Court. Raws li txoj cai dav dav, cov khoom siv ua kom yooj yim dua rau cov laug tab sis xav tau kev npaj ntau dua ntawm pawg thawj coj ua ntej koj pib tiag tiag, thaum DIP xav tau kev txawj ntau dua tab sis teeb tsa tsawg.

Ua ntej peb pib, ntawm no yog txhua yam ntaub ntawv koj xav tau:

• Soldering Hlau nrog txis ntsis
• Hlau Solder
• Solder Flux
• Isopropyl Cawv thiab ntaub so ntswg los ntxuav
• Acid Txhuam
• Pliers (rau kev ua txhuas)
• Solder Wick
• Luam Circuit Board (PCB)

Cov khoom hla dhau qhov Yog tias koj tab tom nrhiav rau cov khoom siv qhia kom paub siv qee qhov ntawm cov ntsiab lus no, sim BEST Electronics kawm paub yuav ua li cas thiaj li siv tau cov khoom siv cob qhia ntawm

Txawm hais tias koj tab tom siv DIP lossis cov khoom siv coj ua axial, cov txheej txheem siv tau zoo ib yam, qhov sib txawv tseem ceeb yog tias DIP's muaj qhov sib txawv thiab ntau tus coj.

Kauj Ruam 1: Soldering Axial Leaded Components

Ua ntej koj pib txheej txheem txheej txheem nws yog ib qho tseem ceeb los npaj qhov chaw. Cov haujlwm no tsuas yog siv ob peb feeb tab sis ua kom yooj yim dua kom tau txais kev sib txuas zoo.

Pib los ntawm kev ntxuav cov khoom sib txuas thiab PCB nrog isopropyl cawv thiab so lawv kom qhuav nrog cov khoom uas tsis yog tsim ua kom kimwipe kom ntseeg tau tias PCB tsis muaj av lossis plua plav. Ntxuav cov hlau txuas los ntawm kev ua kom nws sov thiab so nws ntawm cov ntaub ntub dej uas tsis muaj dej.

Tin lub taub hlau soldering los ntawm kev yaj me me ntawm cov laug rau ntawm qhov ntxeev thiab so nws tawm mus rau daim txhuam cev. Qhov no yuav ua rau nws yooj yim dua rau koj tsav lub cua sov mus rau qhov sib koom ua ke.

Tin cov ntaub qhwv los ntawm kev siv cov laug txuas rau cov pawm thiab siv cov laug txhuam los tshem nws. Qhov no yuav ua kom yooj yim dua rau cov laug los lo rau cov pawm. Ceev faj tsis txhob siv lub zog ntau dhau thaum siv cov laug txhuam, vim qhov no tuaj yeem ua rau puas tsuaj.

Kauj Ruam 2: Khoov Cov Thawj Coj

Thaum tuav ib qho ntawm kev coj ua ntawm cov khoom sib dhos lossis siv "Christmas tsob ntoo" raws li qhia, maj mam thawb lub cev tivthaiv kom txog thaum cov hlau lead tau khoov ntawm 90 degree kaum. Rov hais dua qhov no rau lwm tus thawj coj. (Saib cov vis dis aus cuam tshuam rau cov txheej txheem no ntawm BEST Youtube Channel).

Kauj Ruam 3: Muab Tshooj thiab Txiav Cov Leads

Muab cov khoom tiv thaiv, ua kom ntseeg tau tias cov hlau lead nyob hauv nruab nrab ntawm cov plated hla qhov. Thaum ib feem nyob hauv qhov chaw, khoov cov khoom coj rov qab los tuav cov khoom sib dhos hauv qhov chaw. Txheeb xyuas kom paub tseeb tias cov khoom tiv thaiv ncaj qha rau ntawm PCB.

Txiav cov thawj coj, ua kom ntseeg tau tias tso tawm qhov ntev txaus xws li cov khoom siv tseem nyob hauv qhov chaw, tab sis tsis ntau npaum li cov neeg coj tuaj yeem cuam tshuam nrog lwm yam ntawm lub rooj tsavxwm.

Kauj Ruam 4: Tshaj Tshooj

Siv cov dej ntws mus rau ob sab ntawm PCB los pab ua kom muaj cua sov. Flux yuav pab koj ua kom thaj chaw ua kom huv thiab ua kom ntseeg tau tias qhov ntub tau txaus, yog ib feem tseem ceeb ntawm kev tsim kom muaj kev sib txuas zoo.

Tam sim no pib soldering. Nco ntsoov tsuas yog siv cov laug rau sab hauv qab ntawm lub rooj tsavxwm. Txoj cai rau hla qhov-qhov sib dhos yog tias koj tuaj yeem tso dej ntws tawm ntawm ob sab tab sis muab tshuaj txhuam rau ntawm ib qho nkaus xwb. Thaum tuav PCB nyob rau hauv qhov chaw nrog lub ncoo uas tiv taus cua sov, muab tshuaj txhuam txuas rau ntawm ib sab ntawm cov hlau lead thiab tso cov hlau txhuam taub qhov twg lub ncoo ua tau raws cov hlau lead. Thov ib qho me me ntawm cov laug ntawm qhov no. Tom qab ntawd, txav cov hlau txuas mus rau lwm sab ntawm cov hlau lead txhawm rau txhawm rau ua tus choj txuas.

Rov ua cov txheej txheem qub rau lwm tus coj.

Kauj Ruam 5: Ntxuav thiab Tshawb Xyuas

Ntxuav thiab tshuaj xyuas cov khoom kawg kom paub tseeb tias koj txaus siab nrog cov txiaj ntsig. Qhov sib koom ua ke yuav tsum ci hauv cov xim, nrog cov kab sib txuas ua ke thiab ntub dej zoo rau cov hlau lead. Yog tias koj siv cov hlau tsis muaj hmoov txhuas, qhov sib koom ua ke yuav muaj xim daj dua li yog tias koj siv cov hlau lead-lead solder hlau.

Kauj Ruam 6: Soldering DIP's

Ib yam li ua ntej, ntxuav PCB nrog cawv isopropyl thiab so nws nrog cov ntaub so ntswg.

Ua ib daim ntawv ceeb toom ntawm tus thais lossis tus pin 1 kos rau ntawm tus tivthaiv. Qhov no thais lossis cim yuav tsum nyiam nrog lub thais lossis cim rau ntawm PCB. Ua kom ntseeg tau tias qhov ua kom raug yog ua ntej siv cov laug. DIP's muaj qhov sib txawv rau lawv thiab tsis ua raws lawv kom raug tuaj yeem ua rau puas ntsoog tas mus li.

Kauj Ruam 7: Thov Flux thiab Solder

Thaum ib feem nyob hauv qhov chaw, siv cov dej ntws mus rau kab pheeb ces kaum ntawm sab hauv qab ntawm PCB.

Tack me ntsis ntawm cov laug rau cov coj kom tuav ib feem hauv qhov chaw. Xyuas kom lub cev tivthaiv yaug nrog lub rooj tsavxwm kom ntseeg tau tias muaj kev sib txuas zoo.

Cov kab txuas txuas rau txhua lwm yam hlau lead. Muab qhov taub ntawm koj cov xaim tooj liab tso rau ib sab ntawm cov hlau lead, tom qab ntawd siv lub cua sov me ntsis kom rov ua dua lub lauj kaub. Tsim tus choj txuas uas siv cov txheej txheem ib yam li thaum siv cov khoom siv coj los ua axial. Thaum koj tau ua tiav ib kab ntawm kev sib txuas, rov qab rov qab thiab sau cov lus coj los nruab nrab. Nco ntsoov muab cov hlua khi coj los ua qhov kawg, vim lawv tuav lub nti nyob hauv qhov chaw.

Kauj Ruam 8: Ntxuav thiab Tshawb Xyuas

Ib zaug ntxiv, ntxuav tawm ib qho seem uas yog siv isopropyl cawv thiab tshuaj xyuas qhov sib koom ua ke kom du, ci ntsa iab nrog ntub zoo.
