Jeffrey, In my former lives we had used different colored solder masks, Red for R&D, Blue for Pilot and Green for Production. The rule was red boards could not ship without "papal dispensation", blue boards were expected to be shippable with necessary operational modifications and green should be modification free production stuff. Phil Nutting -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of McGlaughlin, Jeffrey A Sent: Tuesday, April 13, 2004 10:39 AM To: [log in to unmask] Subject: [TN] Prototype Identification I am looking for a "best practice" for identifying engineering prototype boards in a high-mix low-volume production environment. In the past we have been a prototype only facility but are adding the capability to do small run production in house. Since we have more engineers than production techs we often have engineers involved with assembly and need to track their project development boards separately.
