Ua cov kab rov ua haujlwm rov ua haujlwm tuaj yeem kim thiab nyuaj, tab sis ua tsaug muaj qhov yooj yim thiab zoo nkauj daws: Toaster Ovens. Txoj haujlwm no qhia kuv qhov teeb tsa uas kuv nyiam tshaj thiab cov txuj ci uas ua rau cov txheej txheem ua haujlwm tau zoo. Hauv qhov piv txwv no kuv yuav tsom mus rau ua qhov rov ua dua ntawm BGA (pob kab sib chaws).

Kauj Ruam 1: Nrhiav Lub Toaster Cub

Nrhiav lub Toaster Cub

Koj tab tom nrhiav ob yam tseem ceeb, qhov ntsuas kub hloov pauv tau, thiab lub sijhawm ua haujlwm uas yuav poob qis. Qhov tseeb ntau koj tuaj yeem tau txais hauv lub sijhawm zoo dua.

Tsis tas li, yog tias koj tuaj yeem tau txais nws, qee qhov kev txwv huab cua ntws yuav txhim kho qhov sib xws ntawm qhov kub thiab txias, tab sis koj yuav tsum ua kom ntseeg tau tias huab cua ntws tsis muaj zog txaus txav koj cov khoom ib puag ncig.

Kauj Ruam 2: Tau txais tus pas ntsuas kub thiab Timer

Txawm hais tias lub qhov cub toaster muaj qhov ntsuas kub thiab lub sijhawm ua ke, koj tseem xav tau qee qhov kev nyeem kom raug. Tau txais tus ntsuas kub hauv qhov cub pheej yig thiab pov nws sab hauv lub qhov cub thiab tau txais lub sijhawm nrog lub tswb ceeb toom kom ceeb toom koj kom tshuaj xyuas koj cov PCBs ci.

Kauj Ruam 3: Ua Koj Li PCBs

Ua Koj Cov PCBs
Ua Koj Cov PCBs

Hauv qhov kev ntsuam xyuas no kuv tab tom ua haujlwm nrog ADXRS300 uas yog 1 axis Gyrometer ua los ntawm cov cuab yeej siv sib piv. Nws los nyob rau hauv pob khoom kab sib dhos pob nrog pob uas twb tau txuas rau hauv qab ntawm cov khoom siv. PCB yuav tsum tau tsim nrog cov ntaub qhwv rau txhua lub npas, nrog rau daim kab xev tshuaj ntsuam xyuas kom yooj yim kom ua raws cov khoom tiv thaiv (uas yog qhov tseem ceeb thaum koj tsis tuaj yeem pom cov pawm). Tsis tas li, duh, nco ntsoov tias koj kos cim qhov chaw ntawm Tus Pin 1.

Kauj Ruam 4: Ntxiv Flux rau PCB

Ntxiv Flux rau PCB

Cov pob hauv BGA tsis muaj flux yog li koj * kiag li * yuav tsum tso cov dej ntws tawm ntawm lub rooj ua ntej ua qhov rov ua dua. Yog tias koj tsis ntxiv cov dej ntws tawm tom qab ntawd cov oxide nyob rau sab saum toj ntawm cov ntaub qhwv yuav ua rau cov pob tsis ntws thiab koj yuav xaus nrog cov pob me me uas tsis tau txuas nrog rau hauv qab PCB.

Kauj Ruam 5: Kho cov Cheebtsam ntawm PCB

Muab PCB tso rau ntawm lub tais ntawm lub qhov cub toaster, nyiam dua kom koj tuaj yeem khaws qhov muag ntawm nws los ntawm lub qhov rais ntawm qhov cub. Ua qhov tseeb ntawm cov khoom siv ntawm PCB siv cov kab lo lo lo ntxhuav tshuaj ntsuam xyuas kom ua qhov sib luag. Koj tsis tas yuav yog qhov tseeb vim tias cov kab rov ua dua tshiab yuav rub cov khoom sib koom ua ke, tab sis koj yuav tsum sim ua kom ze li sai tau. Cov xwm txheej phem tshaj yuav muaj qhov cuam tshuam los ntawm ntau dua ib nrab ntawm lub pob sib nrug suab uas yuav ua rau cov khoom sib hloov los ntawm ib txheej ntawm cov pawm. Tsis zoo

Kauj Ruam 6: Pib 'Ua Noj

Pib 'Ua noj
Pib 'Ua noj

Kaw lub qhov cub toaster qhov rooj, (xyuas kom tseeb tias koj tsis tsoo cov khoom tiv thaiv kom tsis txhob sib dhos.) Teem qhov ntsuas kub rau ib puag ncig 450 thiab pib lub sijhawm nyob ib puag ncig 20 feeb. Tom qab ib zaug koj tau txiav txim siab tus yam ntxwv ntawm koj lub qhov cub ci ci tshwj xeeb ces koj tuaj yeem pib siv qhov txiaj ntsig tseeb. Tab sis rau tam sim no peb yuav siv peb lub ntsuas cua sov thiab lub sijhawm ntsuas sab nraud kom taug qab seb muaj dab tsi tshwm sim.

Kauj Ruam 7: Saib Qhov Kub

Khaws qhov muag ntawm tus pas ntsuas kub. Koj yuav tsum tau txheeb xyuas qhov reflow profile rau koj cov khoom tshwj xeeb kom paub tias qhov kub koj tab tom sim mus txog. Hauv kuv qhov xwm txheej, cov npas solder yuav pib yaj ntawm 183C thiab kuv xav tsoo qhov kub saum 210C. Yog tias koj mus dhau 230-240C koj yuav pib hlawv koj cov PCBs, uas txawm hais tias lom zem, tej zaum tsis yog yam koj xav tau.

Kauj Ruam 8: Tua Lub Toaster Cub

Sai li lub qhov cub kub tshaj qhov kub koj tab tom npaj rau, tua nws!

Kauj Ruam 9: Cia Nws Txias, thiab Tsis Tsiv Ib Yam Dab Tsi

Cia nws txias, thiab tsis txhob txav ib yam dab tsi!
Cia nws txias, thiab tsis txhob txav ib yam dab tsi!

Koj tuaj yeem ua kom cov txheej txheem txias txias los ntawm qhib lub qhov rooj ntawm lub qhov cub ci … Txawm li cas los xij, nco ntsoov tias koj tsis thab cov khoom lossis txav lawv mus rau ib qho twg. Cov kab laug sab tseem ua kua ntawm qhov no thiab yog tias koj poke ntawm cov khoom koj yuav hloov nws ib puag ncig thiab rhuav tshem nws. Nov yog lub sijhawm tsuas yog mus kev deb xwb. Thaum qhov kub tau poob qis dua 100C (lossis 50C yog tias koj muaj kev tsis txaus ntseeg) koj tuaj yeem xav txav mus ib puag ncig.

Kauj Ruam 10: Tshawb xyuas thiab Txaus Siab

Tshawb xyuas thiab Txaus Siab
Tshawb xyuas thiab Txaus Siab

Koj yuav tsum ua kom ntseeg tau tias txhua lub pob tau txuas nrog thiab cov khoom siv tau txuas nrog rau PCB. Cov duab no qhia 3 ntawm BGAs rov ua ke ua ke hauv 3-axis Inertial Measurement Unit.
