4 Component Library White Papers that You'll Keep on File!

Reading time ( words)

If you’re a PCB Librarian, PCB Designer, ECAD Engineer, NPIE, new to PCB design, involved in PCB manufacturing or anywhere in-between you’ll want to keep these four white papers on file for future reference and guidance. Each paper provides PCB design industry guidance, design best practices and the educational information you need for the surface mount component families that you use the most.

Each paper discusses everything from the land sizes for each of the applicable lead type to the placement courtyard and routing schemes to consider for the different technology and density levels.


Part 1 is dedicated to the creation of Molded Body components. Click here to download.



Part 2 covers the  Small Outline Transistor (SOT). Click here to download.



Part 3 covers BGAs. Click here to download.



Part 4 includes both QFN and PQFNs with pullback leads. Click here to download

Cadence’s Clarity: 'I Can See Clearly Now'

12/03/2020 | Clive "Max" Maxfield, Maxfield High-Tech Consulting
Do you recall the song “I Can See Clearly Now”? This catchy tune was first released by Johnny Nash in 1972, which was three years before I started my BSc in Control Engineering at Sheffield Hallam University, Yorkshire, England. I’ve just been looking at the Clarity 3D Transient Solver from Cadence, so the lyrics I’m hearing in my head are, “I can see clearly now the EMI is gone / I can see all EMC obstacles in my way..."

Stephen Chavez and Happy Holden on Designing Reliable Vias

12/02/2020 | I-Connect007 Editorial Team
Andy Shaughnessy and Happy Holden speak with Stephen Chavez, a staff engineer with an aerospace company and chairman of the Printed Circuit Engineering Association (PCEA), about designing vias for greater reliability. They also address several areas where they can look to improve reliability, a variety of steps that designers should take to help ensure more robust vias, and some testing and educational resources that PCB designers and design engineers should be aware of.

This Month in Design007 Magazine: HDI Design, Landless Vias, VeCS, and More

11/09/2020 | I-Connect007 Editorial Team
Andy Shaughnessy, Happy Holden, and Dan Feinberg recently met with James Hofer, general manager of Accurate Circuit Engineering, to discuss via design techniques and via reliability from the fabricator’s viewpoint. As Hofer explained, even with open lines of communication between the designer and the board shop, there are plenty of variables to contend with regarding proper via design, especially when working with PTFE materials.
