Iindaba-Uyenza njani iFayile ye-Centroid

Kwimimandla ye-PCB, Iinjineli ezininzi ze-elektroniki azi ngenene ukuba loluphi uhlobo lweefayile ezifunekayo kunye nendlela yokudala iifayile ezifanelekileyo zokuhlanganisa umphezulu wokunyuka.Siza kukwazisa ngako konke malunga nayo.Ifayile yedatha yeCentroid.

Idatha ye-Centroid yifayile yomatshini kwifomathi yokubhaliweyo ye-ASCII equka umyili wereferensi, u-X, Y, ujikelezo, icala eliphezulu okanye elisezantsi lebhodi.Le datha yenza ukuba iinjineli zethu ziqhubele phambili nokuhlanganisa umphezulu wentaba ngendlela echanekileyo.

Ukubeka iindawo ezibekwe phezulu kwii-PCB ngokusebenzisa izixhobo ezizenzekelayo, kuyafuneka ukuba wenze ifayile ye-Centroid ukucwangcisa izixhobo.Ifayile ye-Centroid iqulathe zonke iiparamitha zokubeka ukuze umatshini azi apho abeke khona inxalenye kwaye koluphi ulungelelwaniso kwi-PCB.

Ifayile yeCentroid iqulathe olu lwazi lulandelayo:

1. Isalathiso soMyili (RefDes).

2. Umaleko.

3. X indawo.

4. Y indawo.

5. Isalathiso sokujikeleza.

RefDes

I-RefDes imele umyili wereferensi.Iya kuhambelana nebhili yakho yezixhobo kunye ne-PCB markup.

Umaleko

Umaleko ubhekisa kwicala eliphezulu okanye kwicala elingasemva lePCB okanye kwicala apho amacandelo abekwe khona.Abaqulunqi bePCB kunye nabahlanganisi bahlala bebiza amacala aphezulu kunye nasemva kwicala lecandelo kunye necala le-solder, ngokulandelelanayo.

Indawo

Indawo: i-X kunye neNdawo ze-Y zibhekiselele kumaxabiso achonga indawo ethe tye kunye nethe nkqo yecandelo le-PCB ngokubhekiselele kwimvelaphi yebhodi.

Indawo ilinganiswa ukusuka kwimvelaphi ukuya kumbindi wecandelo.

Imvelaphi yebhodi ichazwa njenge (0, 0) ixabiso kwaye ibekwe kwikona esezantsi ekhohlo yebhodi ukusuka kwindawo ephezulu yokujonga.

Kwanecala elingasemva lebhodi lisebenzisa ikona esezantsi ekhohlo njengendawo yesalathiso yemvelaphi.

Amaxabiso endawo ye-X kunye no-Y alinganiselwa kwishumi lamawaka le-intshi (0.000).

Ukujikeleza

Ujikelezo licala lojikelezo lwecandelo lePCB lokubeka ireferensi ebhekiselele kwindawo ephezulu yokujonga.

Ukujikeleza lixabiso le-0 ukuya kwi-360 degree ukusuka kwimvelaphi.Omabini amacandelo aphezulu kunye nokugcinwa kwecala asebenzisa indawo ephezulu yokujonga njengenqaku labo lokubhekisela.

Ezi zilandelayo ziindlela eziphambili zokuyivelisa ngesoftware yoyilo eyahlukeneyo

Ukhozi Software

1. Qhuba i-mountsmd.ulp ukwenza ifayile yeCentroid.

Ungayijonga ifayile ngokuya kwimenyu.Khetha iFayile kwaye emva koko usebenzise i-ULP kuluhlu oluhlayo.Isofthiwe iya kudala ngokukhawuleza i-.mnt (i-mount top) kunye ne-.mnb (i-mount reverse).

Le fayile igcina indawo yamacandelo kunye nolungelelwaniso lwemvelaphi yePCB.Ifayile ikwimo ye-txt.

Isoftware yeAltium

Le software isetyenziselwa ukwenza ukhetho kunye nendawo yemveliso eya kusetyenziswa kwinkqubo yokuhlanganisa.

Kukho iinketho ezimbini zokudala imveliso:

1. Yenza ifayile yoqwalaselo lomsebenzi wokuPhuma (*.outjob).Oku kuya kudala imveliso yejenereyitha eqwalaselwe ngokufanelekileyo.

2. Kwimenyu khetha Ifayile.Emva koko kuluhlu oluhlayo, cofa kwiZiphumo zeNdibano kwaye emva koko Uvelise uKhetho kunye nokubeka iiFayile.

Emva kokucofa, Lungile, uya kubona imveliso kwiKhetha kunye neNdawo yokuSeta ibhokisi yencoko yababini.

Qaphela: Imveliso eyenziwe yiFayile Yoqwalaselo Lwemveliso yoMsebenzi yahlukile kwimveliso eyenziwe nguKhetha kunye noYilo lwebhokisi yencoko yababini.Izicwangciso zigcinwa kwifayile yoqwalaselo xa usebenzisa ifayile yoqwalaselo lwefayile yesiphumo.Nangona kunjalo, xa usebenzisa iKhetha kunye nendawo yokuSeta incoko yababini, izicwangciso zigcinwa kwifayile yeprojekthi.
