PCB ubume:

I-PCB esisiseko ineqhekeza lezinto ezikhuselayo kunye nolwaleko lwefoyile yobhedu, ilaminishwe kwi-substrate. Imizobo yekhemikhali yokwahlula ubhedu ukwahlula umkhondo obizwa ngokuba yimikhondo okanye umkhondo wesekethe, iipads zonxibelelwano, ukugqobhoza imingxunya yokudlulisa unxibelelwano phakathi kweendlela zobhedu, kunye neempawu zendawo eziqhuba kakuhle zokukhusela i-EM okanye ngeenjongo ezahlukeneyo. Iileyili zisebenza njengeengcingo ezigcinwe endaweni kwaye zigqunyiwe omnye komnye ngumoya kunye nezinto zokwenza izinto zePCB. Umphezulu we-PCB unokuba nesigqubuthelo esikhusela ubhedu ekudleni kwaye kunciphise amathuba okusilela kwe-solder phakathi komkhondo okanye uqhagamshelo lombane olungafunekiyo ngeentambo ezingavulelwanga. Ngenxa yokukwazi ukuqikelela ukuwelda iisekethi ezimfutshane, ukutyabeka kubizwa ngokuba kukunganyangeki kwe-solder.

Ukongeza, uyilo oluphambili kunye namanyathelo ayimfuneko afunekayo kuyilo lwe-PCB kufuneka kuxoxwe.

Uyilo olulula lwePCB:

Zininzi i-PCB zokuyila i-tutorials kwi-Intanethi, amanyathelo asisiseko oyilo lwe-PCB kunye nesoftware ephambili yoyilo lwe-PCB esetyenziswayo ngoku. Kodwa ukuba ufuna isikhokelo esipheleleyo kuyilo lolwakhiwo lwePCB kunye neendidi ezahlukeneyo kunye neemodeli, kukho isango elinolwazi kwi-Intanethi malunga nePCBS ebizwa ngokuba yiRAYMING PCB & Iinxalenye. Zonke iiprototypes zePCB kunye nezicelo ezahlukeneyo zePCB, yonke into inokufumaneka kule ndawo yokungena.

Ukuyila i-PCB, kufuneka siqale sizobe umzobo we-PCB. Isikimu siza kukunika iplani ye-PCB, eya kuthi ibeke ubume bayo okanye ilandelele indawo yamacandelo ahlukeneyo kwi-PCB.

Amanyathelo uyilo PCB:

Oku kulandelayo ngamanyathelo ayimfuneko okuyila i-PCB;

Faka isoftware ukuyila iPBB.

Uyilo usebenzisa isoftware yoyilo lwePCB.

Cwangcisa ububanzi bekhebula.

Umbono we-3 d

Isoftware yoyilo lwePCB:

Zininzi izinto ezahlukeneyo kunye nesoftware eluncedo kwintengiso yoyilo lwenxalenye yesicwangciso sePCB. Yile nto icandelo lesicwangciso sePCB libukeka ngayo;

Qonda i-PCB kwaye ufunde uyilo lwe-PCB olulula kunye nokufunda kwakhona kwe-PCB

Umzobo 2: UMzobo weSHEMATIC wesekethe ye-PCB

Ukulungiselela ukuyila icandelo le-PCB, iisoftware ezininzi zisetyenziswa, ikakhulu kusetyenziswa;

I-KiCad

Iproteus

ukhozi

Orcad

Uyilo lwePCB kwiProteus:

Iproteus ngoku isetyenziselwa ukuyila iPCBS. Kulula kakhulu ukuyisebenzisa kwaye nabani na ongayaziyo uya kukhawuleza aqhelane nayo kwaye abe nazo zonke iimpawu. Kungenxa yokuba inonxibelelwano olukhethekileyo kunye nolusebenzisekayo. Unokuzifumana ngokulula zonke izinto ofuna ukuzongeza kwi-PCB yakho. Iintambo ezahlukeneyo kunye nokunxibelelana kwazo kunokwenziwa ngokulula.

Qonda i-PCB kwaye ufunde uyilo lwe-PCB olulula kunye nokufunda kwakhona kwe-PCB

Ukuziqhelanisa nesoftware kubalulekile ekwenzeni umsebenzi. Iproteus ibonelela ngoncedo olukhulu lokufumana zonke izinto eziyimfuneko ofuna ukuba nazo kwi-PCB yakho. Unokufikelela ngokulula kunxibelelwano kunye nazo zonke izixhobo ezivela kwifestile ephambili, njengoko kubonisiwe kumfanekiso ongentla. Abasebenzisi banokubona iimodeli zezinto ezahlukeneyo, ke banokukhetha isixhobo esineemodeli ezithile ukuze bayile i-PCB.

Uyilo olupheleleyo lwePCB olwenziwe kwiProteus lunikezwe apha ngezantsi;

Qonda i-PCB kwaye ufunde uyilo lwe-PCB olulula kunye nokufunda kwakhona kwe-PCB

Umzobo 4: Uyilo loyilo lwePCB

Uyilo olupheleleyo lwe-PCB eyilwe kusetyenziswa isoftware yeProteus iboniswe apha ngasentla. Umntu unokuwabona ngokulula amacandelo ahlukeneyo alungelelaniswe kwaye ahlelwe ngokudibeneyo ukuhlangabezana neemfuno ze-PCB esebenzayo, i-capacitor, i-LED kunye nazo zonke iingcingo ezidityaniswe ngokulandelelana.

Ukuhamba:

Xa inxalenye yesikimu yoyilo lwePCB igqityiwe ngoncedo lwesoftware, iintambo zePCB ziyenzeka. Kodwa ngaphambi kokufaka iintambo, abasebenzisi bePCB banokujonga ubunyani besekethe yoyilo ngoncedo lokulinganisa. Emva kokujonga ubunyani, indlela igqityiwe. Ukuhamba, uninzi lwesoftware lubonelela ngeendlela ezimbini onokukhetha kuzo.

Ukuhamba ngesandla

Ukuhamba ngokuzenzekelayo

Kwindlela yokuhambisa ngesandla, umsebenzisi ubeka icandelo ngalinye ngokwahlukeneyo kwaye alidibanise ngokomzobo wesekethe, ke kwindlela yokuhamba ngesandla, akukho mfuneko yokuzoba umzobo weskim ngaphambi kokufaka iintambo.

Kwimeko yeentambo ezizenzekelayo, umsebenzisi ufuna kuphela ukukhetha ububanzi beentambo. Emva koko i-PCB yenzelwe ukubeka ngokuzenzekelayo izixhobo ngokusebenzisa isoftware ezenzekelayo, emva koko idityaniswe ngokomzobo weskimu owenziwe ngumsebenzisi. Zama indibaniselwano ezahlukeneyo zonxibelelwano kwisoftware yokuhamba ngokuzenzekelayo ukuze iimpazamo zingenzeki. Abasebenzisi banokuyila ii-PCBS ezizodwa okanye ezimbaxa ngokuxhomekeke kwisicelo.

Cwangcisa ububanzi bekhebula:

Ukulandelwa kobubanzi kuxhomekeke kukuhamba ngoku kuyo. Ifomula esetyenzisiweyo ukubala indawo yokulandela umkhondo ngolu hlobo lulandelayo:

Nanku u “Ndi” okwangoku, “δ T” ubushushu buphakama, kwaye “A” ngummandla wokulandela umkhondo. Ngoku ubale ububanzi bomkhondo,

Ububanzi = Indawo / (ubukhulu * 1.378)

K = 0.024 yomaleko wangaphakathi kunye no-0.048 kulwaleko lwangaphandle

Ifayile yokuhambisa i-PCB enamacala amabini ijongeka ngoluhlobo:

Umzobo 1: Ukuhambisa ifayile

Imigca etyheli isetyenziselwa imida ye-PCB, ukunciphisa umda wecandelo kunye nokubekwa kweentambo kwiintambo ezizenzekelayo. Imigca ebomvu neluhlaza okwesibhakabhaka ibonisa umkhondo wobhedu ophantsi kunye nangaphezulu, ngokwahlukeneyo.

Umbono ongu-3:

Isoftware ethile enje ngeProteus kunye neKiCad ibonelela ngembonakalo ye3D, ebonelela ngombono we3D wePCB enamacandelo abekwe kuyo ukuze ibonwe ngcono. Umntu unokugweba ngokulula ukuba isekethe iya kujongeka njani emva kokuba yenziwe. Emva kweentambo, iFayile yePDF okanye yeGerber yocingo lobhedu inokuthunyelwa ngaphandle kwaye iprintwe kwi-negative.
