Allegro는 Skill을 이용하여 BGA 패키지의 자동 부채질 기능을 구현합니다.
9653 단어 02_소프트웨어
BGA 캡슐이 필요한 비트 번호와 오버홀을 직접 지정하여 비트 번호의 자동 슬라이싱 기능(자동 펀치 +오버홀딩 및 용접판 자동 연결)을 구현합니다. 코드는 다음과 같습니다.

1. fanoutVia="Via8d16";직접 구멍을 지정해야 용접 디스크 라이브러리에서 찾을 수 있습니다
2. lineWidth = 6, 이 단계는 용접판에서 구멍이 난 Cline까지의 선가중치를 사용자가 지정할 수 있도록 지정합니다
3. 코드는 마지막으로 원작자의 정보입니다.
코드는 다음과 같이 사용됩니다.
1. Notepad 새 *.il 파일, 그리고 상기 코드를 이 파일에 복사하여 저장하면 됩니다.
2. Allegro 명령줄에서 수행: skill load("*.il의 전체 경로")
3. Allegro 명령줄에:skill을 입력하면 skill 창으로 전환하고 bgafanout("U187"), U187은 사용자가 스스로 선택해야 하며, 리턴이 실행이 끝날 때까지 기다리면 자동으로 부채질을 완성할 수 있다.
하나의 보드에서 자동으로 부쳐야 하는 IC가 많지 않기 때문에, 스스로 위치 번호를 지정하는 것이 사용자에게 더욱 편리할 수 있습니다.
