Agenda

Defining your circuit

• Defining your BOM• Functionality of components.

• Availability of components ?

• Package to use ? Footprint definition.

• Testing implications ?

• Heat Management ?

• Pricing ?

• Etc …

• Schematics

Defining your circuit

• What are the PCB cost drivers ?

• What makes a PCB hard/impossible to make ?

• Which tools are available to help me ?• Offline direct consulting RFQ - All

• Online capability catalogues - All

• Online smart menus - Eurocircuits

Smart menus

Smart menus – buildup validation

• Technical support• Build wizard

• 892 builds

➢ faster prices, faster deliveries, lower costs

Smart menus – technical validations

• Technical support • Technical validation

• > 300 rules

➢ No production delays

Smart menus – classification aide

• Technical support • Classification wizard

• Pattern

• Holes

• Copper weight

➢ No production delays

Smart menus – price guidance

Poolable options– Extra cost expressed

as single coin symbol

Non-poolable options– Extra cost expressed as multiple coin symbol and remark

Smart menus – panel efficiency

• 2-layer,65x55mm in customer panel, +/- 1.600 pieces needed.

• Customer panel of 4x4 has a production panel efficiency factor of 59% and will result into a price per piece of 16.23€/16 = 1.014€.

Smart menus – panel efficiency

• Changing the customer panel to 5x3 will solve all remarks and results into a price per piece of 10.64€/15 = 0.709€ or 30% less by simply permitting us to utilize the production panel space more efficiently.

Make your board layout

• Place your components• Footprints

• PCB Layout• Tracks, vias, …

Bill Of Material - Jibberish

• Different file formats used

• BOM output from CAD system is limited - Cryptic description of component and package

Bill Of Material - editor

• BOM editor:• Detect BOM list format

• Assign column types

• Automated search

Bill Of Material – editor – manual search

• Integrated search on different sources• Eurocircuits component database• Supplier/Manufacturer websites

• Direct access to spec sheets

Component Placement List – editor

• CPL editor - Read and Visualize • Detect CPL format

• Assign column types

• Visualize component locations on PCB data


• Footprint – we check CAD-info against the eC-verified database• Incorrect component chosen. Same device available with different

packages• Incorrect footprint definition in CAD library


• Location• PIN1 vs centroid location in CPL file


• Rotation• Each library can define its own default rotation• Verified against eC standard rotation
