Mukuwona zigawo zisanu ndi zitatu zazikuluzikulu mu PCB

Ndikofunikira kumvetsetsa ndikusiyanitsa zigawo za PCB. Kuti mumvetsetse makulidwe enieni a PCB, kusiyana kwakukulu kumafunikira kuti PCB igwire bwino ntchito kwambiri. Magawo otsatirawa amapezeka mu PCBS zodzikongoletsera. Izi zimatha kusiyanasiyana, kutengera kuchuluka kwa zigawo, kapangidwe kake, komanso kapangidwe kake.

L makina osanjikiza

Ili ndiye gawo lalikulu la PCB. Imagwiritsidwa ntchito ngati chidule cha bolodi. Umu ndi momwe chimayendera cha PCB. Izi zimathandizanso kuti wopanga adziwe komwe kuli zitsimezo ndi kudula kwake.

L sungani wosanjikiza

Chosanjikiza ichi chimafanana ndi chosanjikiza chamakina kuti chitha kugwiritsidwanso ntchito ngati mkombero. Komabe, ntchito yosanjikiza ndikutanthauzira komwe kumayikidwa poyika zida zamagetsi, zingwe zamagetsi, ndi zina zambiri. Palibe gawo kapena dera lomwe lingaikidwe kunja kwa malire awa. Mzerewu umachepetsa kulumikizana kwa zida za CAD m’malo ena.

L yolozera wosanjikiza

Njira yosanjikiza imagwiritsidwa ntchito kulumikiza zida. Magawo awa amatha kupezeka mbali zonse za bolodi. Kukhazikitsidwa kwa zigawo kuli kwa wopanga, yemwe amapanga zisankho kutengera momwe agwiritsidwira ntchito ndi zomwe amagwiritsa ntchito.

L Ndege yokhazikika ndi ndege yamagetsi

Magawo awa ndiofunikira pakugwira bwino ntchito kwa PCB. Ground grounding and distribution of grounding throughout the board board and its zigawo zikuluzikulu. Chingwe champhamvu, komano, chimalumikizidwa ndi chimodzi mwazigawo zomwe zili pa PCB yomwe. Magawo onse amatha kuwonekera pamwamba, pansi, ndikuphwanya mbale za PCB.

L Kugawa ndege

Ndege yogawanika kwenikweni ndiyomwe imagawanika. Mwachitsanzo, ndege yamagetsi yomwe ili pa bolodi itha kugawanika pakati. Theka la ndege yamagetsi imatha kulumikizidwa ku + 4V ndipo theka lina mpaka -4V. Chifukwa chake, zinthu zomwe zili pa bolodi zimatha kugwira ntchito mosiyanasiyana mosiyanasiyana malingana ndi kulumikizana kwawo.

L Chophimba / chophimba chophimba

Chosanjikiza cha silkscreen chimagwiritsidwa ntchito kukhazikitsa zolembera pazinthu zoyikidwa pamwamba pa bolodi. Chophimbacho chimagwira ntchito yomweyo kupatula pansi pa mbaleyo. Magawo awa amathandizira pakupanga ndi kukonza njira.

L wosanjikiza kuwotcherera wosanjikiza

Kulumikizana kwamkuwa ndi kubowola pama board oyenda nthawi zina kumatchedwa zotchinga zotchinjiriza. Mzerewu umasunga fumbi, fumbi, chinyezi ndi zinthu zina zachilengedwe kutali ndi bolodi.

L wosanjikiza wa solder

Gwiritsani solder phala pambuyo msonkhano pamwamba ogwiritsa. Zimathandizira kutulutsa zida ku board board. Imathandizanso kutuluka kwaulere kwa solder mu PCB yopangidwa ndi zinthu zokhala pamwamba.

Zonsezi mwina sizingakhale mu PCB imodzi yokha. Magawo awa amachokera pamapangidwe osindikizidwa a board board. Magulu apangidwe awa amathandizira kuyerekezera makulidwe onse a PCB pomwe makulidwe amtundu uliwonse wa micron amawerengedwa. Izi zikuthandizani kuti mukhale ndi kulolerana kokhwima komwe kumapezeka mumapangidwe ambiri a PCB.
