How to generate a Centroid File

Ezinkambini ze-PCB, Onjiniyela abaningi bezinto zikagesi abazi ngempela ukuthi hlobo luni lwamafayela oludingekayo kanye nendlela yokuwakha amafayela alungile okuhlanganiswa kokukhweza okungaphezulu.Sizokwethula ngakho konke.Ifayela ledatha le-Centroid.

Idatha ye-Centroid iyifayela lomshini ngefomethi yombhalo ye-ASCII ehlanganisa umklami wereferensi, u-X, Y, ukuzungezisa, ohlangothini olungaphezulu noma olungezansi lwebhodi.Le datha yenza onjiniyela bethu bakwazi ukuqhubeka nokuhlanganisa i-surface mount ngendlela enembile.

Ukubeka izingxenye ezibekwe phezulu kuma-PCB usebenzisa okokusebenza okuzenzakalelayo, kuyadingeka ukuthi udale ifayela le-Centroid ukuze uhlele okokusebenza.Ifayela le-Centroid liqukethe wonke amapharamitha wokuma ngendlela yokuthi umshini wazi ukuthi uyibeke kuphi ingxenye nokuthi ikuyiphi umumo ku-PCB.

Ifayela le-Centroid liqukethe ulwazi olulandelayo:

1. Ireferensi Umklami (RefDes).

2. Ungqimba.

3. X indawo.

4.Y indawo.

5. Isiqondiso Sokuzungeza.

I-RefDes

I-RefDes imele umklami wereferensi.Izohambisana nebhili lakho lezinto zokwakha kanye nemakhaphu ye-PCB.

Isendlalelo

Isendlalelo sibhekisela ohlangothini olungaphezulu noma ohlangothini olungemuva lwe-PCB noma uhlangothi lapho izingxenye zibekwe khona.Abaqambi be-PCB nabahlanganisi bavame ukubiza izinhlangothi ezingaphezulu nezihlehlayo ngohlangothi lwengxenye nohlangothi lwe-solder, ngokulandelana.

Indawo

Indawo: Izindawo zika-X kanye no-Y zibhekisela kumanani ahlonza indawo evundlile neqondile yengxenye ye-PCB ngokuphathelene nomsuka webhodi.

Indawo ilinganiswa kusukela kumsuka kuya enkabeni yengxenye.

Umsuka webhodi uchazwa njengevelu (0, 0) futhi itholakala ekhoneni elingezansi kwesokunxele lebhodi ukusuka endaweni yokubuka ephezulu.

Ngisho nohlangothi olungemuva lwebhodi lisebenzisa ikhona elingezansi kwesokunxele njengendawo eyinkomba yomsuka.

Amanani endawo ka-X kanye no-Y akalwa endaweni eyizinkulungwane eziyishumi zamayintshi (0.000).

Ukuzungezisa

Ukuzungezisa isiqondiso sokuzungezisa kokuma kwengxenye ye-PCB okubhekiselwe kuyo ukusuka endaweni ephezulu yokubuka.

Ukuzungezisa kuyivelu engu-0 kuye ku-360 ukusuka kumvelaphi.Kokubili izingxenye eziseceleni ezingaphezulu nezibekiwe zisebenzisa indawo yokubuka ephezulu njengendawo yazo eyinkomba.

Okulandelayo izindlela eziyinhloko zokuyikhiqiza nge-software ehlukene yokuklama

Ukhozi Software

1. Qalisa i-mountsmd.ukuze udale ifayela le-Centroid.

Ungabuka ifayela ngokuya kumenyu.Khetha Ifayela bese usebenzisa i-ULP ohlwini olwehliswayo.Isofthiwe izodala ngokushesha i-.mnt (mount top) kanye ne-.mnb (mount reverse).

Leli fayela ligcina indawo yezingxenye kanye nezixhumanisi zomsuka we-PCB.Ifayela likufomethi ye-txt.

Isoftware ye-Altium

Le software isetshenziselwa ukudala ukukhetha nokukhipha okuzosetshenziswa enqubweni yokuhlanganisa.

Kunezinketho ezimbili zokudala okukhiphayo:

1. Dala ifayela Lokuhlela Umsebenzi Wokukhipha (*.outjob).Lokhu kuzodala ijeneretha yokuphumayo emiswe kahle.

2. Kumenyu khetha Ifayela.Bese kusuka ohlwini olwehliswayo, uchofoze Okukhiphayo Komhlangano bese Ukhiqiza Amafayela Okukhetha Nawendawo.

Ngemva kokuchofoza, KULUNGILE, uzobona okukhiphayo ebhokisini lengxoxo Khetha bese Ubeka Indawo.

Qaphela: Okukhiphayo okudalwe ifayela Lokumisela Umsebenzi Wokukhiphayo kuhlukile kulokho okukhiphayo okudalwe ibhokisi lengxoxo elithi Khetha bese Ubeka Indawo.Izilungiselelo zigcinwa kufayela lokumisa lapho usebenzisa inketho yefayela Lokukhipha Umsebenzi Wokucushwa.Nokho, uma usebenzisa ibhokisi lengxoxo lokukhetha nendawo, izilungiselelo zigcinwa kufayela lephrojekthi.
