Raws li ib tug novice nyob rau hauv PCB board tsim, dab tsi introductory paub koj yuav tsum paub?

Raws li ib tug novice nyob rau hauv PCB board tsim, dab tsi introductory paub koj yuav tsum paub?Teb:

1. Kev taw qhia kev xaim: Cov kev taw qhia layout ntawm cov khoom yuav tsum zoo ib yam li qhov ua tau nrog daim duab schematic.Cov kev taw qhia ntawm kev xaim zoo dua coincides nrog cov duab kos duab.Nws yog feem ntau tsim nyog los ua ntau yam tsis sib xws ntawm qhov chaw vuam thaum lub sijhawm tsim khoom.

2. Kev npaj ntawm cov khoom yuav tsum tsim nyog thiab zoo ib yam, thiab siv zog ua kom zoo nkauj thiab zoo nkauj.

3. Qhov chaw ntawm cov resistors thiab diodes: dav hlau thiab ntsug: (1) pav ca tso tawm: Thaum tus naj npawb ntawm cov khoom siv hauv Circuit Court me me thiab qhov loj ntawm lub rooj tsav xwm Circuit Court loj, nws feem ntau yog tiaj tus.(2) Ntsug: Thaum tus naj npawb ntawm cov khoom siv hluav taws xob loj thiab qhov loj ntawm lub rooj tsav xwm Circuit Court me me, nws feem ntau yog ntsug, thiab qhov sib nrug ntawm ob lub ncoo feem ntau yog 1 txog 210 ntiv tes.

4. Tso lub potentiometer,
Lub hauv paus ntsiab lus ntawm lub rooj zaum IC: (1) Potentiometer: Thaum tsim lub potentiometer, qhov tam sim no yuav tsum tau nce ntxiv thaum lub potentiometer tau hloov kho clockwise.Lub potentiometer yuav tsum tau muab tso rau hauv cov qauv ntawm lub tshuab tag nrho thiab cov kev xav tau ntawm lub vaj huam sib luag, kom deb li deb tau ntawm ntug ntawm lub rooj tsavxwm, thiab tus kov yuav tsum tig tawm sab nraud.(2) IC lub rooj: Thaum siv IC lub rooj zaum, nws yuav tsum tau ua tib zoo saib xyuas seb qhov kev taw qhia ntawm qhov chaw ntawm lub rooj zaum IC puas yog, thiab seb IC pins puas yog.

5. Kev npaj ntawm cov khoom nkag thiab tawm: (1) Qhov cuam tshuam ntawm ob lub ntsiab lus txhuas yuav tsum tsis txhob loj dhau, feem ntau txog 2 txog 310 ntiv tes.(2) Kev nkag thiab tawm yuav tsum tau tsom rau ntawm 1 mus rau 2 sab kom ntau li ntau tau, thiab yuav tsum tsis txhob sib cais.

6. Thaum tsim cov kab kos duab, xyuam xim rau qhov kev txiav txim ntawm cov pins thiab qhov sib nrug ntawm cov khoom yuav tsum tsim nyog.

7. Nyob rau hauv lub ntsiab lus ntawm kev ua kom ntseeg tau qhov kev ua tau zoo ntawm lub voj voog, kev tsim qauv yuav tsum tsim nyog, cov kab hluav taws xob sab nraud yuav tsum tau siv tsawg dua, thiab cov xov hlau yuav tsum tau ua raws li qhov yuav tsum tau ua.

8. Thaum tsim cov kab kos duab, txo cov xaim thiab sim ua kom cov kab sib dhos thiab meej.

9. Qhov dav ntawm lub davhlau ya nyob twg sawb thiab qhov sib nrug ntawm cov kab yuav tsum yog nruab nrab.Qhov sib nrug nruab nrab ntawm ob lub ncoo ntawm lub capacitor yuav tsum nyob ze li sai tau rau qhov sib nrug ntawm lub capacitor leads.

10. Cov qauv tsim yuav tsum tau ua nyob rau hauv ib qho kev txiav txim, piv txwv li, los ntawm sab laug mus rau sab xis, los ntawm sab saum toj mus rau hauv qab.
