We also use a UR conformal coating. In the "olden days" we did have an occasional plastic components which the coating would not adhere to. At that time we masked off those components and did not conformal coat them. ---------- From: CINDY KEMP ORLANDO ISC *8-306-6873 To: dabonz; jasatt; 'mail@ih <[log in to unmask]>' Cc: 'mail@ih <[log in to unmask]>' Subject: FWD: pwb-cca : conformal coating Technet, I'm forwarding this from a colleague.

Question - is this seen as a problem ? I am proposing that a note should be added to our designs as follows: CONFORMAL COAT DEWETTING ON PLASTIC ENCAPSULATED MICROCIRCUIT COMPONENT BODY IS ACCEPTABLE. If there is a better way please let me here from you. What is the real would doing ? thanx; Skip Greb ======================================================================== To learn more about this email exploder (majordomo), including how to unsubscribe from this list, send e-mail to: [log in to unmask] and place the command "help" in the body of the message - subject may be left blank.
