Inkqubo yokuqonda yobugcisa yeBhodi yePCB yeKhodi ye-PCB kukuskena kwiBhodi yeSekethe ukuze iconjweni, emva koko isungulwe kwifayile yebhodi ye-PCB, kwaye ifayile ye-PCB ithunyelwe kumzi-mveliso wokwenza iBhodi yokwenza iBhodi yokwenza ibhodi. Emva kokuba iBhodi yenziwa, izinto ezithengiweyo zithengiswa kwiBhodi yePCB eyenziweyo, kwaye emva koko iBhodi yeSekethe ivavanywa kwaye ihlolwe.

Amanyathelo athile kwiBhodi yePCB ikopi:

Inyathelo lokuqala kukufumana i-PCB. Okokuqala, shicilela imodeli, iiparamitha, kunye nezikhundla zawo onke amacandelo afanelekileyo ephepheni, ngakumbi indlela yeDiode, ityhubhu yemfundo ephezulu, kunye nolwalathiso lomsando. Kungcono ukusebenzisa ikhamera yedijithali ukuthatha iifoto ezimbini zendawo ebalulekileyo. Iibhodi zesekethe zangoku ze-PCB ziqala ngakumbi nangakumbi. Abanye bothutho lweDioode abaqwalaselwanga konke konke.

Inyathelo lesibini kukususa zonke iibhodi ezimbini zeBhodi kwaye Khuphela iibhodi, kwaye ususe i-tin kumngxunya wepad. Coca i-PCB ngotywala kwaye uyibeke kwiskena. Xa iskena isikesensi, kufuneka uphakamise iiphikseli eziskentiweyo ukuze ufumane umfanekiso ocacileyo. Emva koko intlabathi encinci kunye nezantsi kwephepha lemibala lemibala kude kufike ifilimu yobhedu, ibeke kwiskena, qala i-Photoshop, kwaye uskene ezibini ngokwahlukeneyo ngokwahlukeneyo ngombala. Qaphela ukuba i-PCB kufuneka ibekwe ngokuthe tye kwaye ngokuthe nkqo kwiskena, kungenjalo umfanekiso oskeyiweyo awunakusetyenziswa.

Inyathelo lesithathu kukuhlengahlengisa umahluko kunye nokuqaqamba kwe-canvas ukuze icandelo lefilimu yobhedu kunye nenxalenye yefilimu yobhedu inomfanekiso oqinileyo, kwaye emva koko ijike ibe mnyama kwaye ijonge ukuba imigca icacile na. Ukuba akunjalo, phinda eli nyathelo. Ukuba kucacile, gcina umfanekiso njengefomathi ye-BMP ye-BMP ye-BMP kunye ne-BMP ye-BMP ePhezulu.bmp kunye neBot.bmp. Ukuba ufumana naziphi na iingxaki ngemizobo, unokusebenzisa i-phyhop ukulungisa kwaye uzilungise.

Inyathelo lesine kukuguqula iifayile ezimbini zefomathi ye-BMP kwiifayile zefomati yeprotel, kwaye idluliselwe ezimbini kwii-protel. Umzekelo, izikhundla zepali kunye ne-vale zidlulile kwezi zibini ngokusisiseko, zibonisa ukuba amanyathelo angaphambili enziwe kakuhle. Ukuba kukho ukuphambuka, phinda inyathelo lesithathu. Ke ngoko, ukukopisha i-PCB ngumsebenzi ofuna umonde, kuba ingxaki encinci iya kuchaphazela umgangatho kunye nenqanaba lokuthelekisa emva kokukhuphela.

Inyathelo lesihlanu kukuguqula i-BMP yomaleko oPhezulu ukuya phezulu.pcb, inikele ingqalelo kuguqulo kwi-slick ye-silk, etyheli, kwaye emva koko ubeke isixhobo ngokomzobo wesibini. Cima uLawulela emva kokuzoba. Qhubeka ukuphindaphinda de kube zonke iindawo zitsaliwe.

Inyathelo lesithandathu kukungenisa ngaphezulu.pcb kunye ne-bot.pcb kwi-protel, kwaye kulungile ukuzidibanisa kumfanekiso omnye.

Inyathelo lesixhenxe, sebenzisa iprinta ye-laser ukuze uprinte ungqimba kunye nomaleko ongezantsi kwifilimu ebonakalayo (1: 1), faka ifilimu kwi-PCB, kwaye uthelekise ukuba kukho impazamo. Ukuba ichanekile, ugqibile. .

Ibhodi yekopi efana neBhodi yantlandlolo yazalwa, kodwa le yenziwa kuphela. Kuyimfuneko ukuvavanya ukuba ukusebenza kwe-elektroniki kubuchwephesha beCoppi kuyafana nebhodi yokuqala. Ukuba kuyafana, yenziwe nyani.

Note: If it is a multi-layer board, you need to carefully polish the inner layer, and repeat the copying steps from the third to the fifth step. Ewe, ukungcungcuthekiswa kwemizobo kwahlukile. Kuxhomekeka kwinani leendawo. Ngokubanzi, ikopi ekhuphelwa kabini ifuna ukuba ilula kuneBhodi ye-Winder emininzi, kwaye iBhodi yeBhodi ye-Winder yeBhodi yeBhodi kufuneka ifundwe, iBhodi yeBhodi yeBhodi yeBhodi yeBhodi kufuneka inyange ngakumbi kwaye i-vias yangaphakathi kunye ne-Vias ithathe iingxaki kwiingxaki).

Indlela yeBhodi ePhezulu
I-1. Skena iindawo ezingaphezulu nezezantsi zebhodi yesekethe kwaye ugcine imifanekiso emibini ye-BMP.

2. Vula i-Loftware yeBhodi yeSoftware i-Itepcb2005, cofa "Ifayile" "Vula imephu evulekileyo" ukuvula umfanekiso oskentiweyo. Sebenzisa iphepha ukuze usondeza kwiscreen, jonga i-pad, cinezela i-PP ukubeka i-pad, jonga umgca kwaye ulandele umgca we-PT, faka "ukugcina" ifayile ye-B2P.

3. Cofa "Ifayile" kunye "nokuvula umfanekiso" ukuvula enye ingqokelela yomfanekiso wombala;

I-4. Cofa iqhosha "kwaye" vula "kwakhona ukuvula ifayile ye-B2P egcinwe ngaphambili. Sibona iBhodi entsha eKopishwe, yabekwa ngaphezulu komfanekiso-ibhodi efanayo, imingxunya ikwindawo enye, kodwa uqhagamshelo lwe-wiring lwahlukile. Ke sicinezela "Khetha" - "Useto lobeko", cima umgca wenqanaba eliphezulu kunye nesikrini seSilk apha, ushiya i-vias yamandla e-Vias.

5. I-Vias kwi-vieter ephezulu ikwindawo enye njenge-vias kumfanekiso ongezantsi. Ngoku singakwazi ukulandela imigca kwi-feeder ezantsi njengoko senze ebuntwaneni. Cofa "Gcina" kwakhona-ifayile ye-B2P ngoku inezixhobo ezimbini zolwazi ngaphezulu nasezantsi.

I-6. Cofa "Ifayile" kunye "nokuthumela ngaphandle njengefayile ye-PCB", kwaye unokufumana ifayile ye-PCB enezixhobo ezimbini zedatha. Ungayitshintsha iBhodi okanye ikhuphe i-Schematic Diagram okanye uyithumele ngqo kumzi-mveliso wePCB yemveliso

Indlela yeBhodi yeBhodi yeMultilayer:

Ngapha koko, iBhodi yeBhodi ye-With-With yeBhodi kukukhuphela iibhodi ezimbini ezinamacala amabini, kwaye umlinganiso wesithandathu uza kuphinda ukope ezimbini ezinamacala amathathu ... isizathu sokuba iBhodi yeBhodi yeMibala emininzi iyayibona i-wiring yangaphakathi. Sibona njani ukuba iBhodi yangaphakathi yeBhodi yeMultilayer? Ukungahluthwa.

Zininzi iindlela zokuxhuzula, ezinje nge-porosion yosulelo, isixhobo sokutsala isixhobo, njl njl, kodwa kulula ukwahlula iingqengqelo kwaye uphulukane nedatha. Amava asixelela ukuba isitya sichanekile kakhulu.

Xa sigqiba ukukopa iingqimba eziphezulu nezamazantsi ze-PCB, sihlala sisebenzisa i-sandpaper ukuya kwi-faker yendawo yokubonisa ungqimba lwangaphakathi; I-sandpaper yindawo yesiphatho esiqhelekileyo ethengiswa kwivenkile ye-hardware, ihlala i-PCB, kwaye ke ibambe i-sandble kwaye ihlabe i-SANDB (ukuba iBhodi incinci, ucofe i-PCB ngomnwe omnye, kwaye uqhekeze i-sandble iphepha elinye). Eyona ngongoma iphambili kukuyihlamba iflethi ukuze ibe sempilweni.

Isikrini sesilika kunye neoyile eluhlaza icinyiwe, kwaye isikhumba sobhedu kunye nolusu lobhedu kufuneka lichithe izihlandlo ezimbalwa. Ngokubanzi, iBhodi yeBluetooth inokuchithwa kwimizuzu embalwa, kwaye inkumbulo yenkumbulo iya kuthatha imizuzu elishumi; Ewe, ukuba unawo amandla ngakumbi, kuya kuthatha ixesha elincinci; Ukuba unamandla amancinci, kuya kuthatha ixesha elininzi.

IBhodi yokuGcina okwangoku esona sisombululo siqhelekileyo esisetyenziselwa ukubamba, kwaye lelona qoqosho. Singayifumana iPCB elahliweyo kwaye sizame. Ngapha koko, ukugaya iBhodi ayinzima ibhunga. Yinto entle kakhulu. Kuthatha umgudu omncinci kwaye akukho sidingo sokukhathazeka malunga nokutsala iBhodi kwiminwe.

Ukuphononongwa kwesiphumo sokuFunda kwe-PCB

Ngexesha lenkqubo ye-PCB, emva kokuba umenzi wenkqubo lugqityiwe, umzobo wePCB kufuneka uhlolwe ukuze ubonakale ukuba isengqiqweni senkqubo isengqiqweni kwaye ingaba ifuthe elifanelekileyo linokufezekiswa. Ingahlala iphandwe kwezi zinto zilandelayo:
1. Ingaba indlela yoyilo lwenkqubo iqinisekisa i-wirints efanelekileyo okanye i-wiring echanekileyo, nokuba ngaba i-wiring inokwenziwa ngokuthembekileyo, nokuba ukuthembeka komsebenzi wesekethe kunokuqinisekiswa. Kwisakhiwo, kubalulekile ukuba siqonde kwaye sicwangcise ulwalathiso lomqondiso kunye namandla kunye nenethiwekhi ye-wire yomhlaba.

2. Ingaba ubungakanani bebhodi eprintiweyo buhambelana nobungakanani bomzobo wokwenza, ukuba ngaba inokuhlangabezana neemfuno zenkqubo yokwenza imveliso yePCB, nokuba kukho uphawu lokuziphatha. Le ngongoma ifuna ingqalelo ekhethekileyo. Ukubekwa kwesekethe kunye ne-wiring yeebhodi ezininzi ze-PCB zenzelwe kakuhle kwaye ngengqondo, kodwa indawo echanekileyo yesixokelelwano sendawo ihonjisiwe, isiphumo sokuyilwa kwesekethe akunakubekwa kwezinye iisekethe.

3. Nokuba amacandelo angqubana nendawo enemilinganiselo emithathu kunye neyentathu. Nika ingqalelo kubungakanani besixhobo, ngakumbi ukuphakama kwesixhobo. Xa izinto ze-welding ngaphandle kwesakhiwo, ukuphakama akufuneki ukuba ngaphezulu kwe-3mm.

4. Nokuba ulwakhiwo lwezixhobo lude kwaye lucwangciswe, lulungiswe ngokucocekileyo, nokuba zonke zibekiwe. Kwindlela yezinto, hayi kuphela umqondiso wophawu, uhlobo lomqondiso, kunye neendawo ezifuna ingqalelo okanye ukhuseleko kufuneka ziqwalaselwe, kodwa ukuxinana ngokubanzi kwesakhiwo sesixhobo kufuneka kuthathelwe ingqalelo ukufezekisa uxinzelelo lwefowuni.

5. Ingaba izinto ezifuna ukutshintshwa rhoqo, kwaye nokuba ibhodi yeplagi inokufakwa ngokulula kwizixhobo. Ukulula kunye nokuthembeka kokutshintshwa kunye nokunxibelelana kwiindawo ezitshintshiweyo rhoqo kufuneka kuqinisekiswe.
