Yuav ua li cas los tsim cov ntaub ntawv Centroid los ntawm Eagle, Altium thiab ORCAD/ALLEGRO?

Txhawm rau tso qhov chaw mounted rau ntawm PCBs ntawm cov cuab yeej siv tshuab, nws yog ib qho tsim nyog los tsim cov ntaub ntawv Centroid los tsim cov khoom siv. Ib cov ntaub ntawv Centroid muaj tag nrho cov kev tsis sib haum xeeb xws li lub tshuab paub qhov chaw tso cov khoom thiab nyob rau hauv qhov kev taw qhia ntawm PCB. Cov ntaub ntawv Centroid muaj cov ntaub ntawv hauv qab no:

1. Reference Designator (RefDes)

2. Txheej

3. X qhov chaw

4. Y qhov chaw

5. Kev taw qhia ntawm kev sib hloov

RefDes
RefDes sawv cev rau tus tsim siv siv. Nws yuav ua raws li koj daim nqi ntawm cov ntaub ntawv thiab PCB markup.

Txheej
Txheej yog hais txog sab saum toj lossis sab nraub qaum ntawm PCB lossis sab uas muab cov khoom tso rau. PCB fabricators thiab assemblers feem ntau hu rau sab saum toj thiab rov qab sab ntawm cov tivthaiv sab thiab solder sab, feem.

Qhov chaw
Qhov chaw: X thiab Y Qhov chaw xa mus rau qhov tseem ceeb uas txheeb xyuas qhov chaw kab rov tav thiab ntsug ntawm PCB tivthaiv nrog rau lub hauv paus chiv keeb. Qhov chaw yog ntsuas los ntawm lub hauv paus chiv keeb mus rau qhov chaw ntawm qhov chaw. Lub hauv paus chiv keeb yog txhais raws li tus nqi ({{0}}, 0) thiab nyob rau ntawm lub kaum sab laug sab laug ntawm lub rooj tsavxwm los ntawm qhov pom sab saum toj. Txawm tias sab nraub qaum ntawm lub rooj tsavxwm siv lub kaum sab laug qis dua li lub hauv paus ntsiab lus siv. X thiab Y qhov chaw qhov tseem ceeb yog ntsuas rau kaum txhiab ntawm ib nti (0.000).

Kev sib hloov
Kev sib hloov yog cov kev taw qhia ntawm kev sib hloov ntawm PCB tivthaiv qhov kev tso kawm orientation hais los ntawm qhov pom ntawm sab saum toj. Kev sib hloov yog 0 mus rau 360 degree tus nqi los ntawm keeb kwm. Ob qho tib si sab saum toj thiab khaws cia sab hauv siv lub ntsiab lus saum toj kawg nkaus ntawm kev saib raws li lawv cov ntsiab lus siv.

Ib Daim Ntawv Centroid


Cov hauv qab no yog cov lus qhia rau kev tsim cov ntaub ntawv Centroid nrog ntau hom software:

1. Eagle Software

1. Khiav mountsmd.ulp los tsim cov ntaub ntawv Centroid.

Koj tuaj yeem saib cov ntaub ntawv los ntawm kev mus rau cov ntawv qhia zaub mov. Xaiv cov ntaub ntawv thiab mam li khiav ULP los ntawm cov npe dropdown. Lub software yuav sai sai tsim lub .mnt (mount top) thiab .mnb (mount rov qab).

Cov ntaub ntawv no tuav qhov chaw ntawm cov khoom sib txuas nrog rau kev sib koom ua ke ntawm PCB lub hauv paus chiv keeb. Cov ntaub ntawv yog nyob rau hauv hom txt.

2. Altium Software
Cov software no yog siv los tsim cov khoom siv thiab tso tawm uas yuav siv rau hauv cov txheej txheem sib dhos. Muaj ob txoj hauv kev los tsim cov zis

1. Tsim ib daim ntawv tso tawm txoj hauj lwm Configuration (*.outjob). Qhov no yuav tsim ib tug zoo configured tso zis generator.

2. Los ntawm cov ntawv qhia zaub mov xaiv File. Tom qab ntawd los ntawm daim ntawv teev npe poob, nyem rau ntawm Cov Khoom Siv Sib Tham thiab tom qab ntawd Tsim Cov Xaiv thiab Muab Cov Ntaub Ntawv.

Tom qab txhaj, OK, koj yuav pom cov zis hauv Pick and Place Setup dialog box.

Nco tseg: Cov zis tsim los ntawm Cov Ntawv Pov Thawj Txoj Haujlwm Kev teeb tsa yog qhov sib txawv ntawm cov zis tsim los ntawm Pick and Place Setup dialog box. Cov kev teeb tsa tau muab khaws cia rau hauv cov ntaub ntawv config thaum siv Cov Ntawv Pov Thawj Txoj Haujlwm Kev teeb tsa cov ntaub ntawv xaiv. Txawm li cas los xij, thaum siv Pick and Place Setup dialog, cov chaw khaws cia hauv qhov project file.

3. ORCAD/ALLEGRO Software
Cov txheej txheem tsim cov ntaub ntawv Centroil rau Orcad lossis Allegra software zoo ib yam. Los ntawm cov ntawv qhia zaub mov, xaiv Cov Ntaub Ntawv. Tom qab ntawd, hauv daim ntawv teev npe, nyem rau ntawm Export thiab Tso Npe.
 

Nco tseg: Cov txheej txheem no cuam tshuam rau cov versions tshiab ntawm Orcad thiab Allego software. Yav dhau los versions yuav txawv. Nrog rau cov ntaub ntawv tus neeg siv kom paub ntau ntxiv.

Vim li cas thiaj siv SMT?

Electronics nrhiav perforated miniaturization, yav tas los siv plug-in tivthaiv tsis tuaj yeem ua me me.

Cov khoom siv hluav taws xob ua haujlwm tau ua tiav ntau dua, tsis muaj qhov tho qhov ntawm kev sib xyaw ua ke (IC), tshwj xeeb tshaj yog cov nplai loj, cov ICs sib xyaw ua ke, cov khoom siv saum npoo yog tsim nyog.

Batch ntau lawm thiab automation, Hoobkas xav tau tus nqi qis, siab ntim, tsim cov khoom zoo kom tau raws li cov neeg siv khoom xav tau thiab txhim kho lawv cov kev sib tw.

Kev loj hlob ntawm cov khoom siv hluav taws xob, kev sib koom ua ke (IC) kev txhim kho, kev siv ntau yam ntawm cov khoom siv semiconductor.

Lub kiv puag ncig hauv hluav taws xob hauv kev tshawb fawb thiab thev naus laus zis yog qhov tseem ceeb los caum tus qauv thoob ntiaj teb.

SMT yog lub thev naus laus zis tshiab los tsim lub voj voog. Ntau xyoo dhau los, Tib neeg tsim cov khoom siv hluav taws xob siv hluav taws xob, yog li cov khoom siv hluav taws xob yog qhov loj thiab nyuaj rau siv thiab nqa nrog. Yog li ntawd, lub Circuit Court tsim kev taw qhia yog me me, ces tib neeg inveted lub PCB, nws muaj peev xwm muab lub Circuit Court rau ib tug me me PCB, thiab tom qab ntawd cov khoom invented tawm lub resistors, capacitors ntawm lub PCB. Tag nrho cov thev naus laus zis ntsuas hauv cov txheej txheem no yog SMT.

Cov khoom siv hluav taws xob niaj hnub compressed rau hauv ib lub ntim ntawm tsuas yog ob peb feem kaum ntawm cov cuab yeej ncaj qha mus rau qhov chaw sib dhos ntawm cov khoom sib dhos, luam tawm ntawm cov ntawv luam tawm Circuit Board nto qhov chaw ntawm kev sib dhos tshuab.

Piv nrog cov txheej txheem ib txwm muaj, SMT muaj qhov siab ceev, siab ntseeg tau, tus nqi qis, kev sib txawv, suab teb automation thiab lwm yam yam ntxwv.
