I-PCB ephelele esiyibonayo imvamisa iyisimo esijwayelekile esingunxande. Yize imiklamo eminingi iyinxande ngempela, imiklamo eminingi idinga amabhodi wesifunda abunjwe ngokungafanele, futhi amajamo anjalo ajwayele ukuklama. Le ndatshana ichaza ukuthi ungawakha kanjani ama-PCB amise okungajwayelekile.

Kulezi zinsuku, usayizi we-PCB uhlala udonsa, futhi imisebenzi ebhodini lesekethe iyanda. Kuhlanganiswe nokwanda kwejubane lewashi, ukwakheka kuba yinkimbinkimbi ngokwengeziwe. Ngakho-ke, ake sibheke ukuthi ungabhekana kanjani namabhodi wesifunda anobumba obuyinkimbinkimbi.

Njengoba kukhonjisiwe kuMdwebo 1, ukwakheka okulula kwe-PCI Board kungadalwa kalula kumathuluzi amaningi we-Layout.

Kodwa-ke, lapho ukwakheka kwebhodi lesekethe kudinga ukuguqulwa nokuvalelwa okuyinkimbinkimbi ngemikhawulo yokuphakama, akulula kakhulu kubaqambi be-PCB, ngoba imisebenzi kula mathuluzi ayifani naleyo ye-Mechan Cad Systems. Ibhodi yesifunda eliyinkimbinkimbi eliboniswe kuMfanekiso 2 lisetshenziswa ikakhulukazi ezingxenyeni zokufaka ubufakazi bokuqhuma ngakho-ke zincike ekulinganiseleni kwemishini eminingi. Ukwakha kabusha lolu lwazi kuthuluzi le-EDA lingathatha isikhathi eside futhi alisebenzi. Ngoba, onjiniyela bemishini kungenzeka badale indawo ebiyelwe, ukwakheka kwebhodi lesekethe, indawo yokubeka umgodi, kanye nemikhawulo yokuphakama edingwa ngumqambi we-PCB.

Ngenxa ye-arc kanye ne-radius ebhodini lesekethe, isikhathi sokwakhiwa kabusha kungenzeka kube isikhathi eside kunalokho obekulindelwe noma ngabe ukwakheka kwebhodi lesekethe akunzima (njengoba kukhonjisiwe kuMfanekiso 3).

Lezi yizibonelo ezimbalwa nje zezinhlaka zebhodi lesekethe lesekethe. Kodwa-ke, kusuka emikhiqizweni yanamuhla yabathengi, uzomangala ukuthola ukuthi amaphrojekthi amaningi azama ukwengeza yonke imisebenzi kwiphakeji elincane, futhi leli phakethe alihlali lithuthumela. Kufanele ucabange ngama-Smartphones kanye namathebulethi kuqala, kepha kunezibonelo eziningi ezifanayo.

Uma ubuyisela imoto eqashiwe, ungakwazi ukubona isikhonzi sifunde imininingwane yemoto ngesithwebuli esiphathwayo, bese sixhumana ngentambo nehhovisi. Idivayisi nayo ixhumeke kwiphrinta eshisayo yokuphrinta okuthola ngokushesha. Eqinisweni, wonke la madivaysi asebenzisa amabhodi okujikeleza aqinile / aguqukayo

Manje-ke, umbuzo uthi "Ungangenisa kanjani imininingwane echaziwe Yobunjiniyela Emishini kumathuluzi Wokuklama we-PCB?" Ukusebenzisa kabusha le mininingwane emidwebeni emishini kungasusa ukuphindaphindwa komsebenzi, futhi okubaluleke kakhulu, kuqede amaphutha abantu.

Singasebenzisa i-DXF, i-IDF noma ifomethi ye-prostep ukungenisa lonke ulwazi kwisoftware ye-PCB yokubeka ukuxazulula le nkinga. Ukwenza lokhu kungagcina isikhathi esiningi bese kuqeda iphutha lomuntu. Okulandelayo, sizofunda ngalezi zinhlaka ngamunye ngamunye.

I-DXF iyifomethi endala kakhulu futhi esetshenziswe kabanzi, eshintshana ngokuyinhloko idatha phakathi kwezizinda zomshini we-mechay and PCB ngogesi. I-AutoCAD yathuthukisa ekuqaleni kweminyaka yo-1980. Le fomethi isetshenziselwa ikakhulukazi ukushintshana kwedatha okunezinhlaka ezimbili. Iningi labathengisi be-PCB Ithuluzi lisekela le fomethi, futhi lenza lula ukushintshana kwedatha. Ukungenisa / ukuthekelisa kwe-DXF kudinga imisebenzi eyengeziwe yokulawula izingqimba, izinhlaka ezahlukene namayunithi azosetshenziswa kwinqubo yokushintshana. Umdwebo 5 uyisibonelo sokusebenzisa ithuluzi le-Mentor Graphics 'Pads' ithuluzi lokungenisa ukwakheka kwebhodi eliyinkimbinkimbi kakhulu ngefomethi ye-DXF:

Eminyakeni embalwa edlule, imisebenzi ye-3D yaqala ukuvela kumathuluzi we-PCB, ngakho-ke ifomethi elingadlulisa idatha ye-3D phakathi kwemishini namathuluzi we-PCB ayadingeka. Ngenxa yalokhu, ihluzo mentor zithuthukisa ifomethi ye-IDF, eyayisetshenziswa kabanzi ukudlulisa ibhodi yesekethe kanye nemininingwane yengxenye phakathi kwamathuluzi we-PCB namathuluzi wemishini.

Yize ifomethi ye-DXF ifaka usayizi webhodi nobukhulu, ifomethi ye-IDF isebenzisa isikhundla se-X kanye ne-y yengxenye, inombolo yengxenye, nokuphakama kwe-axis yengxenye yezakhi. Le fomethi ithuthukisa kakhulu ikhono ukubona ngeso lengqondo i-PCB ekubukeni okunezinhlangothi ezintathu. Ifayela le-IDF lingafaka neminye imininingwane ngendawo ekhawulelwe, njengokuphakanyiswa kokuphakama ngaphezulu nangaphansi kwebhodi yesekethe.

Uhlelo ludinga ukukwazi ukulawula okuqukethwe okuqukethwe kufayela le-IDF ngendlela efanayo esimweni sepharamitha ye-DXF, njengoba kukhonjisiwe kuMdwebo 6

Enye inzuzo yesibonisi se-IDF ukuthi yiliphi iqembu lingahambisa izakhi endaweni entsha noma lishintshe ukwakheka kwebhodi, bese lidala ifayela le-IDF elihlukile. Ukungathandeki kwale ndlela ukuthi lonke ifayela elimele iBhodi kanye nezinguquko zezakhi zidinga ukungethenjwa kabusha, futhi kwezinye izikhathi, kungathatha isikhathi eside ngenxa yosayizi wefayela. Ngaphezu kwalokho, kunzima ukuthola ukuthi yiziphi izinguquko ezenziwe ngefayela elisha le-IDF, ikakhulukazi emabhodini amaningi wesifunda. Abasebenzisi be-IDF ekugcineni bangadala imibhalo yangokwezifiso ukuthola lezi zinguquko.

Ukuze udlulise kangcono idatha ye-3D, abaklami bafuna indlela ethuthukisiwe, futhi ifomethi yesinyathelo saba khona. Ifomethi yesinyathelo ingadlulisela usayizi webhodi kanye nokwakheka kwengxenye, kepha okubaluleke kakhulu, ingxenye ayiseyona isimo esilula ngenani eliphakeme kuphela. Imodeli ye-Step Contnent ihlinzeka ngokumelwa okunemininingwane nokuyinkimbinkimbi yezakhi zefomu elinezici ezintathu. Yomibili lelo bhodi yesekethe kanye nemininingwane yengxenye ingadluliselwa phakathi kwe-PCB kanye nemishini. Kodwa-ke, alisekho indlela yokulandela izinguquko.

Ukuze sithuthukise ukushintshana kwamafayela wesinyathelo, sethula ifomethi ye-PROSTEP. Le fomethi ingahambisa idatha efanayo ne-IDF nesinyathelo, futhi inentuthuko enkulu - ingakwazi ukulandelela izinguquko, futhi inganikeza amandla okusebenza ohlelweni lwangempela lwesihloko futhi lubukeze noma yiziphi izinguquko ngemuva kokusungula isisekelo. Ngaphezu kokubuka izinguquko, i-PCB kanye nonjiniyela bemishini bangavumela futhi noshintsho lwezakhi ngakunye ekuguqukeni kwesimo se-Layout kanye neBhodi. Bangaphakamisa futhi amasayizi ebhodi noma izindawo zezakhi. Lokhu kukhulumisana okuthuthukile kusungula i-eco (i-Engineering Change Order) engakaze ibe khona ngaphambi kwe-ECAD ne-Mechanical Group (Umdwebo 7).

Namuhla, iningi lezinhlelo ze-ECAD ne-Mechanical CAD zisekela ukusetshenziswa kwefomethi ye-prostep ukuthuthukisa ukuxhumana, ngaleyo ndlela zilondoloze isikhathi esiningi futhi zinciphise amaphutha abizayo angadalwa yimiklamo eyinkimbinkimbi ye-elektromolical. Okubaluleke kakhulu, onjiniyela bangakha ukwakheka kwebhodi lesekethe eliyinkimbinkimbi ngemikhawulo eyengeziwe, bese bedlulisa lolu lwazi nge-elektroniki ukugwema umuntu ovame ukuphinda usayizi webhodi, lapho esonga isikhathi.

Uma ungazange usebenzise lezi dxf, idf, isinyathelo noma amafomethi wedatha we-prostep ukushintshanisa imininingwane, kufanele uhlole ukusetshenziswa kwawo. Cabanga ukusebenzisa le datha yedatha ye-elekthronikhi ukuyeka ukuchitha isikhathi ukuze uphinde uphinde uphinde uphinde ubumbe amabhodi ebhodi yokujikeleza.
