RoHS & WEEE
These two acronyms may seem new
to many of you, but they have actually been around for several years.
They stem from two European Union directives that address the use of hazardous
and toxic substances in electronic products and the ultimate disposal of those
products. Something we all should embrace.
As you transition your operations to produce products
compliant with the RoHS & WEEE directives, Northern Circuits stands ready to
help. We can manufacture your printed circuits using base materials and
surface finishes necessary for compliance with these directives.
Most of the questions we have received from our customers
concerning RoHS & WEEE are about solder alloy and surface finishes.
While these are important questions, laminate selection should not be
overlooked. Standard FR-4 with a glass transition temperature of 140 deg. F just
isn't designed for lead free soldering. Neither are many of the high
temperature laminates. When purchasing circuit boards that will be
subjected to lead free soldering you should specify that the base material be:
"Lead free soldering compatible".
Northern Circuits now has both "Lead free
soldering compatible" and "Halogen free, lead free soldering
compatible" laminates available. Be sure to specify your
requirement when ordering or requesting a quotation.
