I would think that 'whiskering' will require several years to quantify impact. Does anyone know what the typical period is for either whisker or dendrite growth ? In any case, we have had RoHS-compliant products in the field for almost 2 years with no problems.
My initial HALT results were less than what we needed. After several false starts and process 'tweaks', the margins indicated by previous HALTs returned, the birds resumed singing, and the sun continued to shine. But, because some customers demand non-RoHS construction, logistics and parts control probably eats a little more of our overhead. In any case, the manufacturing people need to pay constant and close attention, because RoHS materials seem to be less forgiving of any slight process deviations. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Bill Flanigan Sent: Monday, August 27, 2007 6:22 AM To: [email protected] Subject: Post-ROHS; any defect experiences? Colleagues, Now that we are several months into the ROHS regime, have any of you experienced product non-conformances that you attribute to the new metallurgies? There have been discussions and concerns about 'whiskering' and the legislation - I think - granted an extension to servers. What is the group's experience so far? Is there a forum for this matter anywhere? Respectfully, WmFlanigan Ameritherm Inc - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
