Ndi PCB yatha pamene masanjidwewo amalizidwa ndipo palibe mavuto omwe amapezeka ndi kulumikizanandi kusiyana?

Yankho, ndithudi, ayi. Oyamba ambiri, kuphatikiza mainjiniya odziwa zambiri, chifukwa cha nthawi yochepa kapena kusaleza mtima kapena kudzidalira kwambiri,

amakonda kufulumira, kunyalanyaza kuyang'ana mochedwa, pakhala pali nsikidzi zotsika kwambiri, monga kukula kwa mzere sikokwanira, kusindikiza kwa zigawo

Kupanikizika ndi mabowo otuluka anali oyandikira kwambiri, ma sign mu loop, etc., amatsogolera kumavuto amagetsi kapena njira, yayikulu kusewera bolodi, kuwononga. Chifukwa chake,

kuyendera pambuyo ndi sitepe yofunika pambuyo PCB wakhala anayala.

1. chigawo ma CD

(1) Kutalikirana kwa mapadi. Ngati ndi chipangizo chatsopano, kujambula awo zigawo phukusi, kuonetsetsa kuti katayanitsidwe ndi koyenera. Kutalikirana kwa mapadi kumakhudza mwachindunji kuwotcherera kwa zigawo.

(2) Kudzera kukula (ngati alipo). Pazida zamapulagi, kukula kwa dzenje kuyenera kusungidwa malire okwanira, nthawi zambiri osachepera 0.2mm ndiyoyenera kwambiri.

(3) Chidule cha nsalu yotchinga silika. Kusindikiza kwazithunzi za contour ziyenera kukhala
zazikulu kuposa kukula kwenikweni kuonetsetsa kuti chipangizo akhoza kuikidwa bwino.

2. Kapangidwe

(1) IC siyenera kukhala pafupi ndi m'mphepete mwa bolodi.

(2) Zigawo za dera mu module imodzi ziyenera kuikidwa pafupi ndi wina ndi mzake. Mwachitsanzo, decoupling capacitor ayenera kukhala

pafupi ndi pini yoperekera mphamvu ya IC, ndipo zigawo zomwe zimapanga gawo logwira ntchito lomwelo ziyenera kuyikidwa m'dera lomwelo ndi mawonekedwe omveka bwino.

kuonetsetsa kukwaniritsidwa kwa ntchito.
(3) Konzani malo azitsulo malinga ndi kukhazikitsa kwenikweni. Socket imalumikizidwa ndi ma module ena kudzera mu lead, malinga ndi kapangidwe kake,

kuti muyike bwino, gwiritsani ntchito ma socket oyandikana nawo, komanso pafupi ndi m'mphepete mwa board.

(4) Samalani ndi njira yotulukira. Socket imafunikira njira, ngati mbaliyo ili yosiyana, waya iyenera kuchitidwa. Kwa socket yathyathyathya, malo a soketi ayenera kukhala kunja kwa bolodi.

(5) Pasakhale zida m'malo osungiramo.

(6) Gwero losokoneza liyenera kukhala kutali ndi dera lovuta. Chizindikiro chothamanga kwambiri, wotchi yothamanga kwambiri kapena siginecha yosinthira pakali pano ndi zosokoneza, ziyenera kukhala kutali ndi dera lovutirapo (monga reset circuit, analogi circuit). Akhoza kulekanitsidwa ndi pansi.
