Kom tso saum qhov chaw nto rau PCBs ntawm kev siv cov cuab yeej siv, nws yog qhov tsim nyog los tsim kom tau ib daim ntawv teev npe rau kev zov me nyuam. Ib daim ntawv teev npe hauv phau ntawv muaj tag nrho cov tsis tseem ceeb xws li hais tias lub tshuab paub qhov chaw muab ib qho kev tivthaiv thiab hauv kev cob qhia rau ntawm PCB. Ib cov ntaub ntawv hauv xov hauv nruab nrog cov ntaub ntawv hauv qab no:
Siv Tus Designator (RefDes)
Txheej
X qhov chaw
Y qhov chaw
Kev qhia ntawm kev sib hloov
RefDes
RefDes sawv cev rau tus neeg muab khoom siv. Nws yuav haum rau koj daim nqi ntawm cov ntaub ntawv thiab PCB cim.
Txheej
Txheej hais txog sab saum toj los sab nraud ntawm PCB los yog sab ntawm qhov chaw uas muab tso rau. PCB fabricators thiab assemblers feem ntau hu rau sab saum toj thiab sab nraud ntawm lub tog sab nrauv thiab sab laug sab, raws li.
Qhov chaw
Qhov chaw: X thiab Y Cov Chaw Qhia txog qhov tseem ceeb uas taw qhia qhov chaw nruab nrab ntawm txoj cai ntawm PCB nrog rau tus thawj tswj hwm lub hauv paus. Qhov chaw yog ntsuas los ntawm lub hauv paus chiv keeb mus rau qhov chaw nruab nrab. Tus thawj coj ntawm lub rooj tsavxwm yog txhais tau tias yog tus nqi (0, 0) thiab nyob ntawm sab laug ntawm sab laug ntawm lub rooj tsavxwm los ntawm qhov pom ntawm sab saum toj. Txawm tias sab nraud ntawm lub rooj tsavxwm siv sab qis sab laug raws li keeb kwm qhov chaw siv. Qhov tseem ceeb ntawm qhov chaw X thiab Y yog ntsuas mus rau kaum txhiab ntawm ib nti (0.000).
Kev sib hloov
Kev sib hloov yog qhov kev taw qhia ntawm txoj kev hloov ntawm PCB cov kev qhia txog qhov chaw kawm ntawm qhov kev taw qhia ntawm sab saum toj. Cov kev sib hloov yog 0 txog 360 degree tus nqi ntawm lub hauv paus chiv keeb. Ob qho tag nrho sab saum toj thiab qhov chaw sab nrauv siv qhov pom ntawm sab nraud ntawm qhov lawv xav tau.
Cov nram qab no yog cov lus qhia rau kev tsim cov ntaub ntawv hauv xov tooj nrog ntau hom software:
1. Dav dawb hau Software
Khiav mountsmd.ulp los tsim cov ntaub ntawv hauv xov tooj.
Koj tuaj yeem saib tau cov ntaub ntawv los ntawm kev mus rau hauv cov ntawv qhia zaub mov. Xaiv Cov Ntaub Ntawv thiab ces khiav ULP los ntawm qhov sau cov npe. Tus software yuav ceev nrawm tsim lub .mnt (mount saum) thiab .mnb (mount nraud).
Daim ntawv no tswj xyuas qhov chaw ntawm lub cheebtsam thiab cov haujlwm ntawm PCB lub hauv paus chiv keeb. Cov ntaub ntawv yog nyob rau hauv txt hom.
2. Siv Software
Qhov software no yog siv los tsim qhov tso npe tawm thiab qhov chaw tso tawm uas yuav siv tau rau hauv txoj kev sib dhos. Muaj ob qho kev xaiv tsim cov zis
Tsim ib qho Kev Ua Lag Luam Cov Chaw Ua Hauj Lwm (* .outjob). Qhov no yuav tsim ib qho tsim tawm tso zis generator.
Los ntawm cov ntawv qhia zaub mov xaiv. Tom qab ntawd los ntawm dropdown lub npe, nias rau ntawm qhov sib dhos tawm thiab ces Generates De thiab Muab cov Ntaub Ntawv.
Tom qab txhaj, ua tiav, koj yuav pom qhov kev tso tawm hauv Pick and Place Setup dialog box.
Lus Cim: Cov zis uas tau tsim los ntawm Cov Ntawv Tawm Tawm Hauj Lwm Cov Ntawv Txiav Txim txawv ntawm qhov tso tawm los ntawm Pick and Place Setup dialog box. Cov chaw muab khaws cia rau hauv cov ntaub ntawv config thaum siv Cov Ntawv Tawm Hauj Lwm Configuration cov ntaub ntawv xaiv. Txawm li cas los xij, thaum siv lub Pick and Place Setup dialog, lub tsev kawm ntawv muab cia rau hauv cov ntaub ntawv.
3. ORCAD / ALLEGRO Software
Cov txheej txheem tsim cov ntaub ntawv Centroil rau Orcad lossis Allegra software zoo sib xws. Ntawm daim ntawv qhia zaub mov, xaiv Cov Ntaub Ntawv. Tom qab ntawd, hauv daim ntawv teev npe cia, nyem rau Export thiab Placement.
