Yeah that is about right. We typically see 2-5 micro inches gold over 150 +/- 50 Nickel.

Do these thicknesses look right? Some folks in the company are questioning whether this is standard for most fab houses. Thanks in advance for any insight. ******************************************************* Alexis Meehan Wavespan Corporation Mgr Engineering Srvs 500 N.
