PCB ngokungqinelana nesicelo sebhodi yokuhlela iphaneli enye, iphaneli ephindwe kabini, multilayer PCB; Ngokombandela, kukho ibhodi ye-PCB eguqukayo (ibhodi eguqukayo), ibhodi ye-PCB eqinile, ibhodi ye-PCB eqinileyo Ishicilelwe yiBhodi yeSekethe (i-PCB), ekwabizwa ngokuba yiBhodi yeeSekethi eziPrintiweyo, licandelo elibalulekileyo le-elektroniki, ngumzimba wenkxaso wezinto ze-elektroniki, ngumthengisi wezinto zombane ezihambelana nonxibelelwano ngombane, kuba yenziwa yitekhnoloji yokushicilela ngombane, kunjalo ke ibizwa ngokuba yiBhodi yeeSekethe eziPrintiweyo. A PCB nje ipleyiti obhityileyo equlathe iisekethi ezihlangeneyo kunye nezinye izinto zombane.

Ulwahlulo ngokwenani leengqimba zesekethe

Yahlulahlulwe yiphaneli enye, iphaneli kabini kunye nebhodi enemigangatho emininzi. Ibhodi multilayer eliqhelekileyo idla maleko 3-6, kwaye ibhodi multilayer entsonkothileyo ukufikelela maleko ngaphezulu kwe-10.

(1) Iphaneli enye

Kwibhodi yesekethe eprintiweyo esisiseko, iinxalenye zigxile kwelinye icala kwaye iingcingo zijolise kwelinye. Kuba ucingo lubonakala kwicala elinye kuphela, ibhodi yesekethe eprintiweyo ibizwa ngokuba yiphaneli enye. Iisekethe zakuqala zazisebenzisa olu hlobo lwebhodi yesekethe kuba zazikho izithintelo ezingqongqo kwisekethe yoyilo lwephaneli enye (kuba lalilinye icala, i-wiring ayinakuwela kwaye kufuneka ihanjiswe ngendlela eyahlukileyo).

(2) Iiphaneli eziphindwe kabini

Ibhodi yesekethe ineentambo kumacala omabini. Ukuze iingcingo kumacala omabini zinxibelelane, kufuneka kubekho unxibelelwano olufanelekileyo lwesekethe phakathi kwala macala mabini, abizwa ngokuba ngumngxunya wesikhokelo. Imingxunya yesikhokelo yimingxunya emincinci kwibhodi yesekethe eprintiweyo, igcwalisiwe okanye ifakwe isinyithi, ezinokudityaniswa kwiingcingo kumacala omabini. Iiphaneli eziphindwe kabini zinokusetyenziswa kwiisekethe ezintsonkothileyo kuneepaneli ezizodwa kuba le ndawo iphindwe kabini inkulu kwaye ii-wiring zinokudibana (zinokubethelwa kwelinye icala).

(3) ibhodi Multilayer

Ukulungiselela ukwandisa indawo enokuthi ifakwe ngeengcingo, iibhodi ezinamacala aliqela zisebenzisa iibhodi ezingaphezulu ezizodwa okanye macala amabini. Iibhodi ze-multilayer zisebenzisa iipaneli ezimbini, kwaye zibeke umaleko wokugquma phakathi komaleko ngamnye webhodi emva kokubopha. Inani lemiqolo ebhodini limele inani leengcingo ezizimeleyo, zihlala zililinani, kwaye iqulethe iingqimba ezimbini ezingaphandle.

Isibini, ngohlobo lwendawo engaphantsi

Iibhodi zesekethe eziguqukayo, iibhodi zesekethe eziqinileyo kunye neebhodi eziqinileyo eziguqukayo.

(1) Flexible ibhodi PCB (ibhodi bhetyebhetye)

Iibhodi eziguquguqukayo ziibhodi zesekethe eziprintiweyo ezenziwe kwimiqolo eguqukayo, enesibonelelo sokugoba ukuququzelela ukuhlangana kwezinto zombane. I-FPC isetyenziswe ngokubanzi kwi-aerospace, emkhosini, kunxibelelwano ngeselula, iikhompyuter eziphathwayo, iipheripherali zekhompyuter, i-PDA, iikhamera zedijithali kunye nezinye iinkalo okanye iimveliso.

(2) ziqinile ibhodi PCB

Yenziwe ngesiseko sephepha (esihlala sisetyenziselwa icala elinye) okanye isiseko selaphu leglasi (esihlala sisetyenziselwa amacala aphindwe kabini kunye nolwahlu oluninzi), i-phenolic okanye i-epoxy resin engaphambi kokumitha emva koko laminated ukuphilisa. Olu hlobo lwebhodi yefoyile enxibe i-PCB, siyibiza ngokuba yibhodi eqinileyo. Emva koko yenziwe i-PCB, siyibiza ngokuba yibhodi eqinileyo ye-PCB akukho lula ukugoba, inamandla athile kunye nobungqingqwa bezinto eziqinileyo ezenziwe ngesiseko sebhodi yesekethe eprintiweyo, uncedo lwayo kukuba lunokuqhotyoshelwa kwizinto zombane ukubonelela inkxaso ethile.

(3) iBhodi PCB ziqinile-bhetyebhetye (ibhodi PCB ngqongqo-bhetyebhetye)

Iibhodi eziqinileyo eziguqukayo zibhekisa kwibhodi yesekethe eprintiweyo equlathe indawo enye okanye ezingaphezulu ezibukhali neziguquguqukayo, ezenziwe ngeebhodi eziqinileyo kunye neebhodi eziguqukayo ezilaminethiweyo kunye. Uncedo ipleyiti ngqongqo-bhetyebhetye edityanisiweyo kukuba ayikwazi kuphela ukunika inkxaso ipleyiti yoshicilelo ngqongqo, kodwa unalo neempawu ukugoba ipleyiti bhetyebhetye, nto leyo ukuhlangabezana neemfuno ibandla-ntathu.
