10.7 - Cam350
While modern versions exist (v12, v14, v15+), version 10.7 represents a critical "golden era" release—stable, widely cracked (unfortunately), but functionally robust. This article focuses on its CAM350 10.7: The Engineer’s Deep Dive into a Legacy PCB Verification Workhorse 1. Introduction: The 10.7 Zeitgeist Released in the late 2000s / early 2010s, CAM350 10.7 arrived at a pivotal moment in PCB design. The transition to higher densities (HDI), microvias, and embedded passives was accelerating, but manufacturing tolerances had not yet reached the sub-20µm extremes of today.
import win32com.client cam = win32com.client.Dispatch("CAM350.Application") cam.OpenJob("C:\\pcb_data\\board.cam") cam.SetLayer("TOP_COPPER") cam.SetUnit("Mil", 4) cam.RunDFMCheck("Copper Slivers", "MinArea": 0.5, "MinWidth": 1.0) cam.ExportReport("C:\\reports\\slivers.txt") cam.Quit() The COM object has no event handler for "modal dialog box." If a DFM check finds zero errors, the script hangs waiting for a non-existent "OK" button. Workaround: redirect to a log file. 7. Known Limitations & Workarounds (Engineer’s Notes) | Issue | Symptom | 10.7 Workaround | |-------|---------|------------------| | ODB++ Support | Import fails on v7.0+ | Convert ODB++ to Gerber X2 via third-party tool first. | | Embedded Components | Resistors inside PCB disappear | Manually draw copper on a separate layer; 10.7 doesn't read embedded. | | Backdrilled vias | DRC errors on stub length | Ignore; manually mark backdrill layer as "mechanical." | | Large boards (>24x18") | Panning lag | Disable "Dynamic Redraw" ( View -> Preferences ). | | IPC-2581 import | Not supported | Not supported at all. Use Gerber. | 8. Comparison to Modern CAM350 (v14+) | Feature | CAM350 10.7 | CAM350 15.0 | |---------|-------------|--------------| | UI | Classic MDI (floating toolbars) | Ribbon-based | | HDI Microvia support | Manual | Automated via rules | | Flex/rigid-flex | Separate files | Unified model | | 3D viewer | No (2.5D only) | Yes (OpenGL) | | Scripting | COM/OLE only | COM + JavaScript + Python native | | License cost | $0 (abandonware) or $3k (legacy) | $12k+ annual | 9. Practical Use Case: Rescuing a Legacy Design Scenario: You have Gerber files from 2005 (RS-274D, not X). Modern tools reject them. Cam350 10.7
