Unfortunately, in what is surely another misnomer (and mistake), some people/companies refer to "environmentally friendly" materials (e.g. halogen-free) as "green".

I used to see this frequently in the late 70's and once in a while on older drawings.

The color of the laminate (or the soldermask)? Halogen-free? Compatible with Pb-free assembly? If the latter, what is the Pb-free alternative being used? What material you get will depend on how you (or I suppose more appropriately, the board fabrication house) answered these questions. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Gary Bremer Sent: Wednesday, January 12, 2005 7:18 AM To: [log in to unmask] Subject: [TN] Hello Designer Council members At the company I am working for is calling out matterial .062 thick FR4 green copperclad laminate for their bare board. My question for the form: When this design was done in the Northeast by the electrical engineer and outsourced to a board assembly house as a turnkey component. What type of quality problems can I expect to deal with durning final assembly and final test? What long term (customer returns) problems may result from this? Do the board fabracation houses on the east coast march to a different drummer than the rest of the country? The electrical engineer does not want to change the drawing to specify what laminate matterial he truly intends to use. The last company I worked for also had this same type of problem. The electrical engineer designs/releases and I have to fix his mistakes.
