Halogen-Free Assembly Reliability Phase 2

Idea/Definition Information
Actual Project Stage: 
Implementation
Project Category: 
Halogen-Free
Project Leader Company: 
Dell
Background: 

Several governments in Europe and the Far East are considering regulation to prohibit or restrict the use of certain types of substances in electronic (and other) products.  Within the marketplace, the OEM's have initiated environmentally-preferable purchasing standards that also include restrictions on the use of these substances in certain products.

In order for the electronics industry to continue its commitment to product stewardship, companies throughout the supply chain will need to understand which alternatives are available, as well as the electrical, mechanical and environmental, health and safety properties of these alternatives.  This leads to the following points:

  • System integrators or OEM's are asking the supply base companies to offer and deliver cost efficient, reliable, environmentally safe products.
  • This is a challenge for the supply chain companies because of the large variety of components and assemblies that must be made Halogen-Free.
  • Although some Halogen-Free components and materials are available, there is no information on how they perform when assembled together.
  • HDPUG is proposing a cooperative effort which would give both suppliers and OEMs important information and build confidence in Halogen-Free.
Problem: 

Halogen-Free PCBs and components have different properties and characteristics than do non-Halogen-Free PCB's and components.  The properties of the HF materials are not readily available in.  It would be beneficial for all the industry to have access to key pieces of information about how a product asssembled with only Halogen-Free components and materials performed when subjected to the same test as a non-Halogen-Free product.

Approach: 
  • Indentify a PWB assembly that represents the more complex types of systems that want to go Halogen-Free.
  • Locate suppliers of Halogen-Free components and assemble the boards using a Lead Free process.

Test and evaluate the PWBAs using a full range of PCB level reliability tests and component level tests to verify performance and reliability.
