Subject: [TN] Adhesion, Polymer Coating ( IPC-TM-650 2.4.16 )

Will like to check whether it is a common practice  to subject parylene coated boards to thermal shock cycles before performing adhesion test method in accordance to IPC-TM-650 2.4.16 (similar to ASTM 3955)?

At the same time, Section 4.0 (Apparatus or Material) of IPC-TM-650 2.4.16, does not indicated what tool is used to create the pattern under section 5.2 (though it refer to IPC-DD-135 which is an obsoleted standard) as the line width of the pattern is 0.1mm. Razor blade thickness is about 0.2mm.

Hope to get advice you all.
