PCB ( Ishicilelwe Circuit Board ), eyaziwa ngokuba kwibhodi yesekethe eshicilelweyo, alicandelo elibalulekileyo elektroniki, wandixhasa amacandelo elektroniki, kunye yenethiwekhi uqhagamshelwano lombane inamacandelo elektroniki. Kuba senziwa yoshicilelo elektroniki, ibizwa ngokuba "yoshicilelo" kwibhodi wesekethe.

umsebenzi

Emva kokuba izixhobo electronic yamkela ibhodi eziprintiweyo, ngenxa ukuyondelelana kwendlela ebhodini enye eprintiweyo, iintambo manual luyakhuselwa, kunye nezombane ngokuzenzekelayo ifakwe okanye ezinyusiweyo, soldered ngokuzenzekelayo, kwaye ngokuzenzekelayo ibhaqe ukuqinisekisa umgangatho izixhobo zobuchwepheshe . Ukwandisa imveliso yabasebenzi, ukunciphisa iindleko, kunye nokuququzelela yesondlo.

Development

iibhodi ashicelelweyo ekhulisa ngoomaleko olunye ukuya kabini-Amasa, multi-ezikroziswayo bhetyebhetye, Usabambelele iindlela zabo. Ngenxa uphuhliso oluqhubekayo okuchaneka ophezulu, ezixineneyo kunye nokuthembeka ophezulu, umthamo lifinyele, iindleko lifinyele, kunye nokusebenza kakuhle, ukwenzela ukuba ibhodi eshicilelweyo usabambelele a ukomelela ngamandla kuphuhliso lwezixhobo electronic kwixesha elizayo .

Classification

Ngokutsho nenani lamanqanaba, ibhodi wesekethe yahlulwe ngokweendidi ezintathu eziphambili: panel olunye, panel kabini, kwaye multi-umaleko ibhodi wesekethe.

Eyokuqala ndawo yolawulo olulodwa. Ngomhla PCB ezininzi ezingundoqo, iindawo bebekelwa kwicala elinye kwaye iingcingo bebekelwa kwelinye icala. Ngenxa yokuba wire ibonakala kuphela kwicala elinye, oko kuthiwa ibhodi yesiphaluka lwendaba olunye-.

panel Abangatshatanga basoloko elula ukwenza kunye ephantsi ngeendleko, kodwa sithintelo kukuba abakwazi ukuba isicelo kwiimveliso ukuba nzima kakhulu.

Igqiza double sisongezelelo kwiqela elinye. Xa iintambo umaleko ube mnye ayikwazi ukuhlangabezana neemfuno imveliso elektroniki, lisetyenziswa lenjongo kabini.

Omabini la macala babe imizila yobhedu-evathe, kwaye vias zingasetyenziswa vula imigca phakathi maleko ezimbini ukwenza udibaniso womsebenzisi womnatha oyifunayo.

A ibhodi multi-umaleko libhekisela ibhodi eshicilelweyo ukuba ngeengcamba ezintathu okanye ngaphezulu yomlinganiselo maleko conductive kunye zokwambathisa izinto wasuka therebetween, kwaye iipateni conductive therebetween izinto ezihambelanayo njengoko kuyimfuneko.

iibhodi yesiphaluka Multi-umaleko na imveliso kuphuhliso lolwazi electronic technology bejonge ngesantya esiphezulu, multi-umsebenzi, umthamo omkhulu, umthamo omncinane, ukuxozwa kunye nobunzima ukukhanya.

Ngokutsho kwiimpawu, ibhodi wesekethe wahlulwe ube ibhodi ethambileyo (FPC), ibhodi nzima (PCB), kunye ibhodi ethambileyo kwaye kunzima (FPCB).
