Thank you Graham. I have found variability in the measurement. Often our operators close down the micrometer until the first click of the clutch. If the mike is a little cockeyed, and not perpendicular to the board, there is enough resistance to pop the clutch, hence an inaccurate reading. What did you find bad about the rounded end anvils?

We currently use a Mitutoyo 293-711, it has flat ends, we rounded the sharp edge so as to avoid damage. I find the flat anvils ensure the operator knows they are holding it perpendicular to the PWB. regards, - Graham -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas Pauls Sent: Thursday, June 30, 2011 11:53 AM To: [log in to unmask] Subject: [TN] Conformal Coating Measurement - rounded anvil mikes Good morning all, For those of you that measure conformal coating thickness using micrometers, do any of you use micrometers with ball type or rounded end anvils? If so, what make and model? Thanks. Doug Pauls ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
