Each version introduced capabilities that addressed evolving PCB design trends. The jump from CAM350 v9.5 to CAM350 10.7 brought modernized interface elements. Moving from CAM350 10.7 to CAM350 12.1 delivered performance improvements through multi-threading. And CAM350 14.6 added specialized analysis for flex and rigid-flex designs that simply wasn’t possible in earlier releases.

CAM350 v9.5: The Legacy Foundation

CAM350 v9.5 represented the mature classic interface that many CAM engineers still remember fondly. Released in 2007, this version established workflows that persisted through multiple subsequent releases.

Key Features in CAM350 v9.5

The v9.5 release introduced several important capabilities that improved daily operations:

AutoImport Templates: This feature allowed engineers to save default import settings, eliminating repetitive configuration for standard file formats. For shops processing similar designs repeatedly, AutoImport templates reduced setup time significantly.

ODB++ Netlist Reference: CAM350 v9.5 added support for using CAD netlists directly from ODB++ imports as reference data. This improved electrical verification accuracy when comparing against extracted netlists.

License Borrowing: Engineers gained the ability to borrow floating licenses for offline work, useful for travel or remote operation without network access.

Vista Compatibility: Windows Vista support ensured the software remained functional on current operating systems of that era.

Netlist Extract Performance: Algorithm updates improved processing speed for large designs, addressing a pain point for complex multilayer boards.

System Requirements for CAM350 v9.5

Component	Requirement
Operating System	Windows XP, 2000, NT, Vista
Processor	1 GHz or faster
Memory	512 MB RAM
Disk Space	200 MB available
Architecture	32-bit

By today’s standards, these requirements seem minimal. However, CAM350 v9.5 was designed for the hardware capabilities of its time and runs surprisingly well on period-appropriate machines.

Limitations of CAM350 v9.5

The major constraints of v9.5 become apparent when compared to modern requirements. No support for ODB++ version 8.0 or IPC-2581 revision B means newer design data may not import correctly. The 32-bit architecture limits memory utilization on complex designs. And the lack of multi-threading means analysis runs on a single processor core regardless of available hardware.

CAM350 10.7: Interface Modernization

CAM350 10.7 marked a significant interface evolution while maintaining familiar command structures. This version introduced the Navigation Pane and Project Explorer that changed how engineers interact with design data.

Major Improvements in CAM350 10.7

Navigation Pane and Project Explorer: The new Project Explorer bar provided hierarchical views of layers, components, nets, Dcodes, and drill tools. Engineers could select and highlight multiple data items simultaneously, keeping them visible during investigation and modification. This dramatically improved workflow efficiency compared to the dialog-based approach of CAM350 v9.5.

Design Compare: A completely new feature in v10.x series, Design Compare allowed engineers to verify changes between design revisions. This capability proved invaluable for ECO verification and catching unintended modifications.

Xpedition CrossProbing: Cross-probing support expanded beyond Allegro to include Mentor Xpedition, allowing bidirectional navigation between CAM350 and the source PCB tool.

Flip Panel Support: Enhanced panelization features supported flip panel configurations common in double-sided assembly processes.

BluePrint-PCB Integration: Direct reading and writing of BluePrint-PCB files enabled smoother documentation workflows.

VB Macro Encryption: CAM350 10.7 added macro encryption capability, protecting intellectual property when distributing automated workflows.

Clear Silkscreen Enhancement: The utility for removing silkscreen from solder mask openings was updated to handle any combination of data types, not just drawn silkscreen.

Why Some Shops Still Use CAM350 10.7

Several factors keep CAM350 10.7 in active use. The interface represents a balance between modern convenience and familiar workflows. Licensing costs for existing perpetual licenses make upgrade decisions non-trivial. And for shops processing standard rigid PCBs without advanced HDI or flex requirements, v10.7 capabilities remain adequate.

CAM350 12.1: Performance and Standards Update

CAM350 12.1 delivered the most significant interface overhaul since the v10.x series, adopting Microsoft’s Ribbon interface paradigm while adding substantial performance improvements through multi-threading.

New Features in CAM350 12.1

Ribbon-Based Interface: The transition from toolbars and menus to function-based ribbons aligned CAM350 with contemporary Windows application standards. Context-sensitive ribbons present object-specific commands based on current selection, reducing menu navigation.

Multi-Threading Support: Perhaps the most impactful change for daily work, CAM350 12.1 implemented multi-threading in DFM analysis algorithms. On multi-core systems (which by 2015 were universal), analysis processing became 3-5 times faster for some designs. This alone justified upgrades for shops running extensive DFM checks.

IPC-2581 Revision B Support: Full import and export support for IPC-2581 Rev B ensured compatibility with designs from CAD tools outputting the updated standard.

ODB++ Version 8.0 Support: Similar compatibility updates for ODB++ v8.0 maintained interoperability with current design tool exports.

NC Tool Table Enhancements: New options in the NC tool table allowed defining hole types including through drill, backdrill, dual drill, via, laser via, blind via, and buried via. This intelligence improved DFM analysis accuracy.

Enhanced Detection Algorithms: Improved detection for backdrills, laser vias, and global fiducials addressed requirements for HDI designs becoming more common.

Negative Plane Analysis: Expanded checks for negative plane layers included minimum width detection, minimum gap between copper elements, and anti-pad to anti-pad spacing verification.

Dockable Interface Panes: Interface elements could be detached from the main application window, hidden when not needed, or auto-hidden to maximize workspace area.

CAM350 12.1 System Requirements

Component	Requirement
Operating System	Windows 7, 8, 8.1, 10 (64-bit)
Processor	2 GHz multi-core recommended
Memory	8 GB RAM minimum
Disk Space	1 GB available

Visual Basic API with Record and Playback: A complete rewrite of automation capabilities, CAM350 14.6 implemented a full Visual Basic scripting environment. The embedded VB editor supports script debugging, and record/playback functionality allows capturing command sequences without manual coding. This superseded the previous proprietary macro language while maintaining backward compatibility.

Rigid-Flex DFM Analysis: Over 39 new flex and rigid-flex specific DFM checks address manufacturability concerns unique to these designs:

• Trace fracture detection in bend areas
• Via presence in flex regions
• Trace corner analysis
• Solid copper in bend zones
• Coverlay exposure verification
• Coverlay to soldermask overlap checking
• Silkscreen ink in coverlay exposure detection

Inter-Layer Analysis: Beyond flex-specific checks, CAM350 14.6 introduced customizable inter-layer analysis. Engineers can define constraints between any two layer types for annular ring, coincidence, minimum gaps, and other conditions.

Net Bridge Support: For designs with intentional shorts, net bridge import/export, assignment, and management prevent false error reporting during netlist comparison.

IPC-2581 Revision C Support: Updated standard support includes via in pad and net bridge definitions per the Rev C specification.

OpenGL Graphics Acceleration: A new 2D graphics engine based on OpenGL improves display performance, particularly noticeable when zooming and panning complex designs.

Expanded Rigid-Flex Layer Types: Support for Conductive Foil, Conductive Film, and Dielectric Bondply layer types ensures accurate import of flex/rigid-flex stackup data from CAD systems.
