Kuwotcherera kwa PCB board

Thekuwotcherera kwa PCBndi ulalo wofunika kwambiri pakupanga PCB, kuwotcherera sikungangokhudza mawonekedwe a bolodi ladera komanso kukhudza magwiridwe antchito a bolodi. The kuwotcherera mfundo PCB dera bolodi ndi motere:

1. Pamene kuwotcherera bolodi PCB, choyamba fufuzani chitsanzo ntchito ndi ngati pini malo akukwaniritsa zofunika. Pamene kuwotcherera, choyamba kuwotcherera zikhomo ziwiri m'mbali mwa phazi losiyana kuti muwayike, ndiyeno yesani imodzi ndi imodzi kuchokera kumanzere kupita kumanja.

2. Zigawo zimayikidwa ndi kuwotcherera mu dongosolo: resistor, capacitor, diode, transistor, Integrated circuit, chubu champhamvu kwambiri, zigawo zina ndizochepa poyamba kenako zazikulu.

3. Powotcherera, pakhale malata mozungulira cholumikizira, ndipo akhale wowotcherera mwamphamvu kuti asawotchere.

4. Pamene soldering tini, malata sayenera kukhala kwambiri, pamene solder olowa ndi conical, ndi bwino.

5. Mukatenga kukana, pezani kukana kofunikira, tengani lumo kuti mudule chiwerengero chofunikira cha resistors, ndi kulemba kukana, kuti mupeze.

6. Chip ndi m'munsi ndi zochokera, ndipo pamene kuwotcherera, m'pofunika mosamalitsa kutsatira malangizo kwa kusiyana pa bolodi PCB, kotero kuti kusiyana kwa Chip, m'munsi ndi PCB zimagwirizana.

7. Mutatha kukhazikitsa ndondomeko yomweyi, yikani ndondomeko ina, ndipo yesetsani kuti kutalika kwa resistor kukhale kofanana. Pambuyo kuwotcherera, mapini owonjezera omwe amawonekera pamwamba pa bolodi losindikizidwa amadulidwa.

8. Pazigawo zamagetsi zomwe zimakhala ndi zikhomo zazitali kwambiri (monga ma capacitors, resistors, etc.), ziduleni mwachidule mutatha kuwotcherera.

9. Pamene dera likugwirizanitsidwa, ndi bwino kuyeretsa pamwamba pa dera ndi wothandizira kuyeretsa kuti muteteze zitsulo zachitsulo zomwe zimayikidwa pamwamba pa bolodi la dera kuchokera kufupi-circuit dera.

10. Mutatha kuwotcherera, gwiritsani ntchito galasi lokulitsa kuti muwone ngati pali kuwotcherera ndi kufupikitsa.
