Ishicilelwe yiBhodi yeSekethe Intshayelelo

A Ibhodi yesekethe mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

Iibhodi zesekethe ezinamacala amabini zintsonkothe ​​kancinci kunePCB esecaleni elinye. Ezi bhodi ziqulethe nje umaleko omnye we-substrate yesiseko. Nangona kunjalo, ziqulathe iileya ze-conductive kwicala ngalinye. Basebenzisa ubhedu njengento eqhubayo. Masingene nzulu ngaphakathi kwiPCB enamacala amabini ukuze sifunde ngakumbi!

Ulwakhiwo kunye nezixhobo zePCB enaMacala aMbini

Isixhobo sePCB esinamacala amabini anokwahluka ngokohlobo lweprojekthi. Nangona kunjalo, izinto eziphambili ziphantse zifana nazo zonke iibhodi zeesekethe. Nangona kunjalo, ubume bePCB buyohluka ukusuka kuhlobo ukuya kolunye.

I-Substrate: Yeyona nto ibalulekileyo eyenziwe nge-fiberglass. Ungayijonga njengohlaka lwePCB.

Uluhlu lweCopper: Isenokuba yifoyile okanye icopper egcweleyo. Yiyo loo nto ixhomekeke kuhlobo lwebhodi. Isiphumo sokugqibela siyafana nokuba usebenzisa i-foil okanye i-copper coating. Iibhodi zeesekethe ezinamacala amabini ziqulethe umaleko wobhedu oqhubekileyo kumacala omabini.

Imaski yeSolder: Luluhlu olukhuselayo lwepolymer. Ngoko ke, ikhusela ubhedu kwi-short-circuititing. Unokuyiqwalasela njengesikhumba sebhodi yesekethe. Ukuthengiswa kwePCB emacala amabini linyathelo elibaluleke kakhulu lokuqina.

I-Silkscreen: yinxalenye yokugqibela yesikrini sesilika. Nangona ingenayo nayiphi na indima ekusebenzeni kwebhodi yesekethe. Abavelisi bayisebenzisa ukubonisa amanani ayinxalenye. Amanani amacandelo abaluleke kakhulu kwiinjongo zokuvavanya. Ukongeza, unokuprinta iilogo zenkampani yakho okanye olunye ulwazi ngendlela yokubhaliweyo.

Izinto eziluncedo kunye nezingeloncedo kwiiBhodi zeSekethe ezinamacala aMbini

Nazi ezinye iibhodi zesekethe eziprintiweyo ezinamacala amabini:

Izinto eziluncedo kwiiBhodi zeSekethe ezinamacala amabini

Umgangatho ophezulu: Ukucwangcisa kunye nokuyila le PCB kufuna isixa esihle somsebenzi. Isiphumo kwiibhodi zeesekethe ezikumgangatho ophezulu.

Isithuba esaneleyo saMacandelwana: Igcina indawo eninzi yamacandelo. Kuba amacala omabini omaleko ayaqhuba.

Iinketho ezingakumbi zoYilo: Ineeleya zokuqhuba macala omabini. Unokuqhoboshela amacandelo ahlukeneyo e-elektroniki kumacala omabini. Ngoko unokhetho oluninzi loyilo.

Ukukhangela kunye nokuTyakala okwangoku: Ngelixa uyisebenzisa njengomaleko ongezantsi, ungawusebenzisela ukutshona kunye nokukhangela okwangoku.

Ukusetyenziswa: Ngenxa yokusebenza kwayo kakuhle, ungayisebenzisa kwizicelo ezininzi.

Ukungalungi kweebhodi zeSekethe ezinamacala amabini

Iindleko eziphezulu: Ukwenza amacala omabini aqhube, kuza ngexabiso eliphezulu kancinane.

Umyili onesakhono uyafuneka: Kubandakanya inkqubo yokwenziwa kwePCB enamacala amabini enzima ukuyilwa kwayo. Ke ngoko, udinga iinjineli ezinobuchule ngakumbi kwimveliso yazo.

Ixesha leMveliso: Ixesha lokuvelisa lingaphezulu kwePCB esecaleni elinye ngenxa yobunzima bayo.

Ukusetyenziswa kweeBhodi zeSekethe ezinamacala aMbini

Olu hlobo lwebhodi yesekethe lwandisa ubuninzi beesekethe. Babhetyebhetye ngakumbi ngokunjalo. Phantse bonke abavelisi bePCB abamacala amabini bayisebenzisa kwizinto ezininzi zombane. Apha ngezantsi kukho imeko ephawulekayo yokusetyenziswa kweebhodi zesekethe ezinamacala amabini:

I-HVAC kunye nezibane ze-LED

Inkqubo yokulawula izithuthi

Iideshibhodi zeemoto

Lawula iilayidi kunye nokuguqulwa kwamandla

Abalawuli kunye nezibonelelo zombane

Ukuvavanya nokubeka iliso kwizixhobo ezahlukeneyo

Iiprinta kunye neenkqubo zeselula

Oomatshini bokuthengisa.
