Yintoni umbala webhodi ye-PCB, njengoko igama libonisa, xa ufumana ibhodi ye-PCB, eyona nto uyibonayo umbala weoyile kwiBhodi, yiyo le nto siyibiza ngokuba ngumbala webhodi yePCB. Imibala eqhelekileyo ibandakanya eluhlaza, iblowu, ibomvu kwaye imnyama, njl. Lindela.

I-1. I-inki eluhlaza isetyenziswa kakhulu, yeyona imbise kakhulu, kwaye iphantsi kwimarike yangoku, iluhlaza isetyenziswa linani elikhulu labavelisi njengombala ophambili weemveliso zabo.

2. Phantsi kweemeko eziqhelekileyo, iMveliso yeBhodi yePCB iyonke kufuneka ihambe ngenkqubo yebhodi kunye neenkqubo ze-SMT ngexesha lenkqubo yemveliso. Xa usenza iBhodi, kukho iinkqubo ezininzi ekufuneka zingene kwigumbi eliphuzi, kuba olu luhlaza lutyhongelo lwegumbi lokukhanya lungcono kuneminye imibala, kodwa esi asisosizathu siphambili.

Xa izinto ezithengiswayo kwi-SMT, i-PCB kufuneka ihambe ngeendlela ezinje ngomthengisi paste kunye ne-patch kunye nokuqinisekiswa kokugqibela kwe-AOI. Ezi nkqubo zifuna indawo yokujonga kunye nokulinganisa. Umbala ongemva oGreen ungcono ukuchongwa kwesixhobo.

I-3. Imibala eqhelekileyo ye-PCB ibomvu, ityheli, iluhlaza, iblowu kwaye imnyama. Nangona kunjalo, ngenxa yeengxaki ezinje ngenkqubo yokuvelisa, inkqubo yokuhlola imigangatho yemigca emininzi kusafuneka ixhomekeke ekubonakalenisweni kwamehlo ngaphandle kweliso kunye nokwamkelwa kwabasebenzi (kunjalo, uninzi lwetekhnoloji yokuvavanya i-probeng probe isetyenziswa ngoku). Amehlo ahlala ejonge ebhodini phantsi kokukhanya okuqinileyo. Le yinkqubo yomsebenzi odinayo kakhulu. Ukuthetha, luhlaza okona kunokuba yingozi emehlweni, ke uninzi lwabavelisi kwimarike ngoku basebenzisa i-PCB eluhlaza.

4. Umgaqo obomvu kwaye umnyama kukuba banxibe ngendlela efanayo nemibandela ye-cobalt kunye nekhabhoni, enayo yokuqhutywa kombane, kunye neengxaki zesekethe ezinokubakho xa amandla enzeka. Ngapha koko, i-PCB eluhlaza inobuhlobo ngokwendalo, kwaye kwindawo yobushushu obuphezulu xa isetyenziswa phakathi, ngokubanzi akukho gesi inetyhefu iya kukhutshwa.

Kukwakhona inani elincinci labavelisi kwimarike esebenzisa iibhodi ezimnyama zePCB. Esona sizathu siphambili kwezi zizathu zibini:

Ujongeka uphezulu;
Ibhodi emnyama akukho lula ukubona i-wiring, ezisa inqanaba elithile lobunzima kwiBhodi yeKhephe;

Okwangoku, uninzi lweebhodi ezingena kwi-Android zii-PCB ezimnyama.

5. Ukusukela kumanqanaba aphakathi kunye nokufika kade, ishishini sele liqalile ukunikela ingqalelo kumbala webhodi yeBhodi yeBhodi yeBhodi yeBhodi yeBhodi yeBhodi yeBhodi yeBhodi yeBhodi ePhezulu, kufuneka iluhlaza ukuba umbala uluhlaza, kufuneka isuke ngaphezulu.
