CAD 환경 변화에 따른 라이브러리 관리 방법

신 CAD 환경 도입시 기존 CAD 환경과 병행해서 운영하는기간이 필요.

기존 라이브러리 관리— 신 CAD 환경에서 사용할 수 있도록 변환 필요

신규 라이브러리 관리— 기존 CAD 및 신 CAD 환경에서 동시에 사용할 수 있도록 생성 필요

LP Wizard (Land Pattern Wizard)

Land Pattern synonyms:— Decal – PADS — Cell – Expedition — Model, Geometry – Board Station— Footprint – Allegro — CAD library part – All CAD tools — ‘Land Pattern’ is the IPC standards term

More than 500,000 different component packages exist

Every unique component package requires a unique land pattern

What’s Included in the LP Wizard?

LP Viewer— Provides access to a company’s CAD library documentation

LP Calculator— Auto-generates accurate land patterns from component dimensions on

라이브러리 변환 Scope 및 조건 정의— 라이브러리 작성은 Board Station에서 하고, 변환기를 사용하여

Expedition 라이브러리로 변환— UI control을 최소화 하기 위해서 Batch 파일을 사용하여 쉽게

변환해야 할 것— 라이브러리 구성 요소 중에 변환 대상은 Symbol과 Geometry로

한정— lua 스크립트 파일을 명령어 라인에서 실행하는 방법— 변환 중 또는 변환 후, Target 라이브러리 보정 사항 도출 (Layer

Mapping 등) 및 보정 자동화

Symbol 변환 방법

Symbol 변환— Design Architect에서 Symbol 생성— 생성된 Symbol을 Design Manager에서

C:\Translations\LMS2LMC\BS_Library\BS_DEVLIB\components\da_

comps 폴더에 복사— C:\Translations\LMS2LMC\Scripts\sym_trans.bat를 실행해서

DxDesigner Symbol로 변환— EE Library Manager에서 Library Service 기능을 사용해서 변환된

Symbol을 Production 라이브러리에 등록

22

Geometry 변환 방법

Geometry 변환— Librarian에서 Geometry 생성— 생성된 Geometry와 함께 연관된 Padstack을

C:\Translations\LMS2LMC\BS_Library\BS_DEVLIB\geometries

폴더에 복사 또는 저장— C:\Translations\LMS2LMC\Scripts\cell_trans.bat를 실행해서

Expedition Cell로 변환— EE Library Manager에서 Library Service 기능을 사용해서 변환된

Cell을 Production 라이브러리에 등록

결론 및 기대효과

제시한 솔루션 사용으로 두 개의 CAD 운용환경에서라이브러리 관리자의 라이브러리 작성시간을 단축

Translator를 사용한 환경 구성일 경우— 기존에 보유하고 있는 CAD License를 활용하여 구축 가능— 변환 후, Automation을 사용한 커스토마이징으로 사업부

특화환경 적용 가능 및 매뉴얼 조작 최소화

라이브러리 전체 작성시간 단축 및 표준화, 균등한품질확보를 위해서는 상용 솔루션(LP Wizard) 추천
