How to generate a Centroid File

Muminda yePCB, Mazhinji mainjiniya emagetsi haanyatsoziva kuti rudzii rwemafaira anodiwa uye maitiro ekugadzira mafaera akakodzera ekusangana kwepamusoro pegomo.Tichakuzivisai zvese nezvazvo.Centroid data file.

Centroid data ndiyo faira yemuchina mune ASCII mavara mafomati ayo anosanganisira referenzi dhizaini, X, Y, kutenderera, kumusoro kana kuzasi kwebhodhi.Iyi data inogonesa mainjiniya edu kuti aenderere mberi nekusangana kwepamusoro pegomo nenzira kwayo.

Kuisa nzvimbo dzakaiswa pamusoro pePCBs kuburikidza neatomatiki michina, zvinodikanwa kugadzira iyo Centroid faira kuronga michina.Iyo Centroid faira ine ese anomira ma paramita zvekuti muchina unoziva pekuisa chikamu uye mune yakatarisa paPCB.

A Centroid faira ine ruzivo runotevera:

1. Reference Designator (RefDes).

2. Layer.

3. X nzvimbo.

4. Y nzvimbo.

5. Kutungamira Kwekutenderera.

RefDes

RefDes inomirira referensi dhizaini.Ichaenderana nebhiri rako rezvinhu uye PCB markup.

Layer

Layer (Layer) zvinoreva divi repamusoro kana reseri rePCB kana divi rinoiswa zvinhu.PCB vanogadzira uye vanounganidza vanowanzodaidza kumusoro uye kumashure mativi chikamu chechikamu uye solder side, zvichiteerana.

Nzvimbo

Nzvimbo: Iyo X uye Y Nzvimbo dzinoreva kukosha kunozivisa yakachinjika uye yakatwasuka nzvimbo yePCB chikamu maererano nekwakabva bhodhi.

Nzvimbo inopimwa kubva pamavambo kusvika pakati pechikamu.

Mabviro ebhodhi anotsanangurwa se (0, 0) kukosha uye iri pakona yezasi kuruboshwe rwebhodhi kubva kumusoro kwekutarisa.

Kunyangwe divi rekumashure rebhodhi rinoshandisa kona yezasi yekuruboshwe senzvimbo yereferenzi yekwakabva.

Hwaro hwenzvimbo yeX uye Y hunoyerwa kusvika pazviuru gumi zve inch (0.000).

Kutenderera

Kutenderera igwara rekutenderera kwechikamu chePCB chekumisikidza chinonongedzwa kubva kumusoro kwemaonero.

Iko kutenderera ndeye 0 kusvika 360 degree kukosha kubva pamavambo.Zvese zviri zviviri kumusoro uye zvakachengeterwa mativi zvikamu zvinoshandisa nzvimbo yepamusoro yekuona senge yavo yekunongedza.

Kutevera inzira huru dzekuigadzira neyakasiyana dhizaini software

Eagle Software

1. Mhanya mountsmd.up kugadzira iyo Centroid faira.

Iwe unogona kuona iyo faira nekuenda kumenyu.Sarudza Faira uye wobva wamhanya ULP kubva pakudonha runyoro.Iyo software ichakurumidza kugadzira iyo .mnt (mount top) uye .mnb (mount reverse).

Iri faira rinochengetedza nzvimbo yezvikamu pamwe chete nemakongiresi ekwakabva PCB.Iyo faira iri mu txt fomati.

Altium Software

Iyi software inoshandiswa kugadzira iyo yekunhonga uye nzvimbo inobuda iyo ichashandiswa mukuita gungano.

Pane nzira mbiri dzekugadzira zvinobuda:

1. Gadzira Output Job Configuration file (*.outjob).Izvi zvinogadzira jenareta yakanyatsogadziriswa.

2. Kubva pane menyu sarudza Faira.Wobva wabva pakudonhedza runyoro, tinya paGungano Zvinobuda uye wozogadzira Sarudza uye Isa Mafaira.

Mushure mekudzvanya, OK, uchaona zvinobuda mubhokisi rebhokisi rePick and Place Setup.

Cherechedza: Izvo zvakabuda zvakagadzirwa neOutput Job Configuration faira zvakasiyana kubva kune zvakabuda zvakagadzirwa nePick and Place Setup dialog box.Izvo zvigadziriso zvinochengetwa mufaira rekugadzirisa paunenge uchishandisa Output Job Configuration faira sarudzo.Nekudaro, kana uchishandisa iyo Pick uye Nzvimbo Setup dialog, marongero anochengetwa mufaira reprojekiti.
