Zeziphi Iindidi ezahlukeneyo zeePCBs?
Iiyunithi zePCB zikhona kwiifom ezininzi zezicelo ezahlukeneyo. Ukukhetha isakhiwo esifanelekileyo semveliso kuya kufuna ukuba injineli ithathele ingqalelo ukusetyenziswa okucetywayo kwesixhobo, imilinganiselo yaso kunye neenkcukacha zaso zamandla. Phonononga oku kulandelayo ukuze uqonde iintlobo zeebhodi zeesekethe eziprintiweyo kwaye zeziphi iintlobo ezifanelekileyo kwiinzame zakho:
Ii-PCB ezicalanye: Ukwenziwa kwe-PCB kubandakanya ukwenza ibhodi yesekethe kuluhlu olunye lwe-substrate kunye nomaleko obhityileyo wentsimbi. Onke amacandelo athengiswa kwicala elinye.
Ii-PCB ezinamacala amabini: Uhlobo lwe-PCB apho amacwecwe esinyithi asebenzayo asetyenziswa kumacala omabini e-substrate.
Imingxuma inokugrunjwa embindini webhodi yesekethe ukuvumela unxibelelwano lubaleke macala omabini.
Ii-PCB ze-Multilayer: Ubuncinane be-PCBs ezinomaleko-mbini ezipakishwe phezulu kwenye zinemigangatho emininzi yokugquma ukunqanda ukuhanjiswa kobushushu. Iiglu ezikhethekileyo ezincamathelayo zigcina uthotho lweePCBs kunye.
Ii-PCB eziguquguqukayo: Iibhodi zesekethe eziprintiweyo ezibonisa ii-substrates eziguquguqukayo ukunceda iinjineli ukuba ziqhelane neemilo zemveliso ezihlangeneyo. Itekhnoloji inokubakho ngendlela yolwakhiwo olumacala omabini, olunamacala amabini okanye olwakhiweyo.
IiPCB eziqinileyo: Ziluncedo kwiimveliso zabathengi ezigcina imilo efanayo kubo bonke ubomi babo. Ii-PCB eziqinileyo zenziwe kusetyenziswa ii-substrates ezirhabaxa ezimelana nokujijeka.
I-Rigid-flex PCBs: Iibhodi zesekethe eziprintiweyo zisebenzisa zombini izinto eziqinileyo neziguquguqukayo. Olu lungelelwaniso luvumela abaphuhlisi bemveliso ukuba bagcine indawo, njengoko iindlela zokudibanisa eziqinileyo kunye neziguquguqukayo zingabandakanywa kwibhodi yesekethe efanayo.
I-Aluminiyam-backed PCBs: Uhlobo lwe-PCB oluthatha indawo ye-aluminiyam substrate apho i-fiberglass iya kuba khona. Idizayinelwe ukusetyenziswa ngePCB enamandla amakhulu ombane njengezibane ze-LED.
High-frequency PCBs: Ibhodi yesekethe yenzelwe ukuthumela imiqondiso eyomeleleyo njenge-2 GHz.
Zenziwa Ngantoni IiPCB?
Inkqubo yokwenziwa kwe-PCB ijongeka ngokwahlukileyo ngokusekelwe kwinjongo ekujoliswe kuyo yeyunithi kunye nokuba angakanani amandla ayimfuneko ukwenza isixhobo sombane sisebenze. Phambi kokukhetha imathiriyeli yendibano yebhodi yesekethe, luluvo oluhle ukuba uziqhelanise neenxalenye ezine eziphambili zeyunithi yePCB:
I-Substrate: Isakhelo sesakhiwo sebhodi yesiphaluka - onke amacandelo agxininise kulo mhlaba.
ILaminates: Izinto ezibamba zonke iileyile zePCB kunye.
Imaski yeSolder: Ihlala phezu kweefoyile zobhedu ngeenjongo zokwahlula kwaye ikhusela uqhagamshelo olusuka kwizinto zokusingqongileyo.
I-Silkscreen: Ibotshelelwa kwimaski ye-solder ukuze izinto zibhalwe.
Yintoni isicwangciso?
I-schematic, okanye i-schematic diagram, yimbonakaliso yezakhi zenkqubo usebenzisa i-abstract, i-graphical symbols endaweni yemifanekiso yenyani.
