Going Vertical
The annual IPC trade show was bigger and more built up than ever, which had the (unintended) net effect of making attendance look like it was down. Still, the show had its share of innovations – albeit primarily on the assembly side – that made the trip to San Diego worthwhile. READ MORE...

IPC-CC-830B vs. the ‘Real World’
A variety of commercially available, internationally qualified conformal coatings were applied in varying thicknesses to SIR coupons by dip, spray and selective-spray, then
subjected to thermal shock. The results demonstrated that the flat FR-4 test board used for IPC-CC-830 qualification does not adequately stress conformal coatings during thermal shock testing, leaving open the question whether the standard is
sufficient for simulating actual use environments. READ MORE... -
The Design Tool Challenge: More Functionality, but Easier to Use
Board designers want tools that enable sophisticated analysis and features like MCAD-ECAD and rigid-flex but without requiring an advanced degree to use them. READ MORE...

The 3 Challenges Facing the Future of PCB Design
Changing demographics is driving demand for system-oriented tools. What we can also expect in the short-term are tools that accommodate more "part-time" users as the number of dedicated PCB designers declines. READ MORE...

Breaking the Silos
Architectural validation and modular design are driving designers to more product- and team-centric approaches. READ MORE...

How Clean is Clean Enough?
A test matrix investigated 12 ionic contaminants in five concentrations to assess the electrical response under controlled heat and humidity conditions. The study used the limits per J-STD-001 for surface insulation resistance. The tests determined at what level of contamination and spacing the ionic/organic residue has a failing effect on surface insulation resistance. READ MORE...

01005: Size Does Matter
Designing PCBs with 01005 components involves tighter constraints in regard to component spacing, layout, and other related considerations, as well as access to higher levels of automation at assembly. READ MORE...

Designing Flex Circuits for Wearable Electronics
The human body has very few flat, rigid surfaces, and standard PCBs don’t easily conform to its various contours. This is where flexible circuitry really shines. But while flex circuits are able to conform to the many twists and turns of a human body, they still have limitations. READ MORE...
