Non-Copper Flexible Circuit Applications - While pure copper is the most common choice for flexible circuit fabrication, there are times a different metal is more suitable for an application.   Copper is well known for its excellent electrical and thermal conductivity, but there are applications where “the best” thermal or electrical conductivity can be a disadvantage. Flexible heater circuits often use metals other than pure copper. Higher resistance copper alloys are popular substitutes f...

Specifying a Flexible Circuit - Flexible circuits are custom engineered parts built to a set of engineering and documentation requirements.  The IPC Association, a global trade association for participants in the electronics industry, has created a specification document, IPC 6013, which is referenced for many flexcircuit applications. This commercial document, in combination with the CAD data and print, is used as the product specification.  Most of All Flex’s internal quality standards ar...

Preventative Maintenance and Flex Circuit Fabrication - Many manufacturing operations rely heavily on equipment and machinery to build product.   Properly maintained equipment is a vital part of supplying a quality product at a predictable delivery schedule.   The amount of resources spent on maintenance varies from business to business.   A company’s philosophy and execution strategy in regards to maintenance typically falls in one of the following three categories: No Formal Preventative ...

Flexible Circuit Prototypes - Most electronic projects begin with at least one build of prototype parts before moving into volume manufacturing.  But the definition of a flexcircuit prototype can vary considerably from one project to another.  In many cases a prototype build is only a few parts used to verify form, fit and function.  In other instances a prototype must not only satisfy the requirement of form, fit and function but the materials and processes used in the prototype stage are ...

Environmental effects on flexible circuit fabrication - Humidity and temperature can be a major factor in many manufacturing organizations, including flexible circuit fabricators.   Humidity is the amount of moisture in the air.  The most common way that we discuss humidity is in terms of relative humidity (RH), which is the percent of moisture in the air relative to the full saturation point at a given temperature.  So when ambient air is at 100% humidity, the air cannot hold any more wate...

Lead free soldering flexible circuits - Ever since the European community adopted the RoHS directive in 2006 the US electronics industry has been steadily increasing its use of lead free solder.  Medical was the first US industry to go totally lead-free.  Today, a significant percentage of electronics soldering is done with lead-free solder.  After several years of refinement and withstanding some mischaracterizations, lead-free soldering is proving to be cost effective and reliable. While ...

FAQ on RoHS as it applies to flexible circuits - What is RoHS? RoHS stands for Restriction of Hazardous Substances.  In 2003 the European Union (EU) adopted a standard that restricts the use of certain materials in electronic products and electronic equipment.  The standard officially became a directive in July 2006.  The intent is to reduce the environmental impact of known hazardous materials.  Currently the following materials are restricted under RoHS: Lead < 1000 ppm Mercury < 100 ppm ...

Soldering Flexible Circuits - The most common methods for component attachment on flexible circuits and rigid printed circuit boards involve soldering.  The basic principles for soldering are the same for both flex and hard board, but soldering components to flexible circuits involves certain specific considerations vs. our rigid cousins.  The nuances are related to material handling and flexibility; reflowed solder is not flexible and can fracture under the various stresses a circuit may e...
