Mu mapangidwe a PCB, masanjidwe a zigawo ndi amodzi mwa maulalo ofunikira. Kwa akatswiri ambiri a PCB, momwe angayale zigawo moyenera komanso moyenera ali ndi miyezo yakeyake. Tafotokozera mwachidule luso la masanjidwe, pafupifupi zotsatirazi 10 Mapangidwe a zida zamagetsi ayenera kutsatiridwa!

1. Tsatirani ndondomeko ya masanjidwe a "chachikulu choyamba, kenako chaching'ono, chovuta choyamba, chosavuta poyamba", ndiko kuti, mabwalo ofunikira a ma unit ndi zigawo zikuluzikulu ziyenera kuikidwa poyamba.

2. Chojambula cha block block chiyenera kutchulidwa mu kamangidwe, ndipo zigawo zikuluzikulu ziyenera kukonzedwa molingana ndi kayendedwe kake kazitsulo ka bolodi.

3. Kukonzekera kwa zigawozo kuyenera kukhala koyenera kukonzanso ndi kukonza, ndiko kuti, zigawo zazikulu sizingayikidwe mozungulira zigawo zing'onozing'ono, ndipo payenera kukhala malo okwanira kuzungulira zigawo zomwe ziyenera kusinthidwa.

4. Pazigawo zozungulira za dongosolo lomwelo, gwiritsani ntchito dongosolo la "symmetrical" momwe mungathere.

5. Konzani masanjidwewo molingana ndi miyezo ya kugawa kofananira, pakati pa mphamvu yokoka, ndi masanjidwe okongola.

6. Mtundu womwewo wa zigawo za plug-in ziyenera kuikidwa kumbali imodzi mu X kapena Y malangizo. Mtundu womwewo wa zigawo za polarized discrete ziyenera kuyesetsanso kusasinthika mu X kapena Y kuti zithandizire kupanga ndi kuyendera.

7. Zinthu zotentha ziyenera kugawidwa mofanana kuti zithetse kutentha kwa veneer ndi makina onse. Zipangizo zozindikira kutentha kupatula zomwe zimazindikira kutentha ziyenera kusungidwa kutali ndi zida zomwe zimatulutsa kutentha kwakukulu.

8. Kukonzekera kuyenera kukwaniritsa zofunikira zotsatirazi momwe zingathere: kugwirizanitsa kwathunthu ndi kochepa momwe zingathere, ndipo mzere wofunikira kwambiri ndi wamfupi kwambiri; mkulu voteji, lalikulu panopa chizindikiro ndi otsika panopa, otsika voteji ofooka chizindikiro ali olekanitsidwa kwathunthu; chizindikiro cha analogi ndi chizindikiro cha digito zimasiyanitsidwa; chizindikiro chafupipafupi Kusiyanitsidwa ndi zizindikiro zotsika; masitayilo a zigawo zamtundu wapamwamba ayenera kukhala wokwanira.

9. Mapangidwe a decoupling capacitor ayenera kukhala pafupi kwambiri ndi pini yamagetsi ya IC, ndipo kuzungulira pakati pake ndi magetsi ndi nthaka ziyenera kukhala zazifupi kwambiri.

10. Pakapangidwe kagawo, kulingalira koyenera kuyenera kuganiziridwa pakuyika zida zogwiritsira ntchito mphamvu yomweyo monga momwe kungathekere kuti zithandizire kulekanitsa magetsi amtsogolo.
