Xa uyila imveliso ye-elektroniki okanye isekethe, esinye sezigqibo ezisisiseko oya kujongana naso kukukhetha uhlobo lwebhodi yesekethe eprintiweyo (PCB) oza kuyisebenzisa.Iinketho ezimbini eziqhelekileyo zi-PCB enamacala amabini kunye ne-PCB enecala elinye.Ngelixa bobabini benezinto zabo ezilungileyo kunye neengxaki zabo, ukwenza ukhetho olufanelekileyo kunokuqinisekisa ukuphunyezwa kweprojekthi ngempumelelo.Kule bhlog, siza kujonga nzulu kwiimpawu zeePCB ezinamacala amabini kunye neePCB ezicalanye ukukunceda wenze isigqibo esinolwazi.
PCB enamacala amabini.
I-PCB enamacala amabini ibonisa imikhondo yobhedu kunye namalungu kumacala omabini ebhodi, adityaniswe nge-vias okanye afakwe kwimingxuma.Ezi vias zisebenza njengamatonela e-conductive, evumela imiqondiso ukuba idlule kwiimaleko ezahlukeneyo ze-PCB, iyenza icwebezele kwaye isebenziseke.Ezi bhodi ziqhele ukusetyenziswa kwizixhobo zombane ezintsonkothileyo ezinjengee-smartphones, izixhobo zekhompyuter, kunye nezicelo ezinoxinano oluphezulu.
Izinto ezilungileyo zePCB enamacala amabini.
1. Ukuxinana kwecandelo elongeziweyo: IiPCB ezinamacala amabini zinokuthatha amacandelo amaninzi, zibonelela ngenqanaba eliphezulu lokusebenza kubungakanani obubambeneyo.Oku kubalulekile xa kuyilwa iinkqubo ezintsonkothileyo zombane.
2. Izakhono eziphuculweyo ze-wiring: Ngeendlela zobhedu kumacala omabini ebhodi, abaqulunqi banokhetho oluninzi lwe-wiring, ukunciphisa ithuba lokuphazamiseka kwesignali kunye ne-crosstalk.Oku kuphucula imfezeko yomqondiso kunye nokusebenza ngokubanzi.
3. Iindleko-zokusebenza: Naphezu kokuntsonkotha kwayo, ii-PCB ezinamacala amabini azibizi kakhulu ngenxa yokusetyenziswa kwazo ngokubanzi kunye nokufumaneka kwazo.Zinokuveliswa ngokufanelekileyo kwinqanaba, zizenze zibe yinto esebenzayo kwiiprojekthi ezinkulu.
Ukungalungi kwePCB enamacala amabini
1. Uyilo oluntsonkothileyo: Ukuntsokotha kwePCB enamacala amabini kwenza inkqubo yoyilo ibe nzima ngakumbi, ifuna isoftware entsonkothileyo kunye nabayili abanamava.Oku kuqhuba iindleko zophuhliso zizonke zeprojekthi.
2. Imingeni ye-soldering: Ekubeni iikhomponenti zikhona kumacala omabini, i-soldering ingaba ngumngeni ngakumbi, ngakumbi kumacandelo e-surface Mount technology (SMT).Unonophelo olongezelelweyo luyafuneka ngexesha lokuhlanganisana ukuphepha iisekethe ezimfutshane kunye neziphene.
PCB enecala elinye
Kwelinye icala, iPCB enecala elinye lolona hlobo lulula lwePCB, enamalungu kunye nemikhondo yobhedu ekhoyo kwicala elinye kuphela lebhodi.Ezi ntlobo zePCBs ziqhele ukusetyenziswa kwizicelo ezingantsonkothanga kangako njengezinto zokudlala, izixhobo zokubala, kunye nexabiso eliphantsi lombane.
Izinto ezilungileyo zePCB enecala elinye
1. Ukuyilwa ngokulula: Xa kuthelekiswa nePCB enamacala amabini, iPCB enecala elinye kulula ukuyilwa.Ubulula boyilo bukhawuleza iprototyping kunye nokunciphisa ixesha loyilo.
2. Ukunciphisa iindleko zophuhliso: Ii-PCB ezisecaleni zineendleko eziphantsi kunye neengqimba zobhedu ezimbalwa kunye noyilo olulula, okwenza ukuba zilungele iiprojekthi eziphantsi kwebhajethi okanye iiprojekthi ezineemfuno ezilinganiselweyo zokusebenza.
3. Inkqubo ye-welding elula: Onke amacandelo akwicala elinye, ukuwelda kuya kuba lula, kulunge kakhulu kubathandi be-DIY kunye nabasakhulayo.Ukongeza, ukuncitshiswa kobunzima kwenza kube lula ukulungisa iingxaki.
Ukungalungi kwePCB enecala elinye
1. Izithintelo zeNdawo: Unyino olubalulekileyo lweePCB ezicalanye sisithuba esincinci esikhoyo samacandelo kunye neendlela.Oku kunciphisa ukusetyenziswa kwabo kwiinkqubo eziyinkimbinkimbi ezifuna ukusebenza okuphezulu okanye i-wiring ebanzi.
2. Ukuphazamiseka kweSignali: I-PCB enecala elinye ayinalo umbane wamandla ozimeleyo kunye nomgangatho womhlaba, oya kubangela ukuphazamiseka komqondiso kunye nengxolo, echaphazela ukusebenza kunye nokuthembeka kwesekethe.
Ukhetho phakathi kwe-PCB enamacala amabini kunye ne-PCB ecala-nye ixhomekeke kubunzima kunye neemfuno zeprojekthi yombane.Ii-PCB ezicalanye zilungele usetyenziso olulula kunye nokusebenza okulinganiselweyo, ngelixa ii-PCB ezinamacala amabini zibonelela ngokuguquguquka okukhulu, ukuxinana kwecandelo eliphezulu kunye nokuphuculwa kobuchule bomzila kwiinkqubo ezinzima ngakumbi.Cinga izinto ezifana neendleko, iimfuno zendawo, kunye neenjongo zeprojekthi ngokubanzi ukumisela uhlobo lwe-PCB olufanelekileyo.Khumbula, uphando olululo, ucwangciso, kunye nokubonisana nomyili we-PCB onamava zibalulekile ekuphunyezweni ngempumelelo kweprojekthi yakho.
