Subject: Re: [TN] Serigraphy Method
Dear Muthu
we sometimes face with the problem that the edges and the sides of the
traces or tracks and conductive patern can not be coverd fully. so this is
what you understand?. what do you think about this? is it always possible to
cover edges with the technology of serigraphy. Or do you have any standard
or criteria which specify the amount of covering of the edges and sides.

Mustafa,
You mean after printing solder mask is not covering the traces at the edges
of the panel.

Subject: [TN] Serigraphy Method
Dear Sir/Madam
We have been coating 35 micron Copper Clad Laminates(CCL)with the
techonology of serigraphy by using U.V Solder Mask. We rarely failed to coat
the sides and edges of the conductive paterns completely. By considering
serigraphy method, up to which limit or criteria this coating is
acceptable?. Is it always possible to coat every edges and sides of
conductive paterns with serigraphy method ?. We sometimes have quarrel with
our customers about this subject. Can you help us to overcome this quarrel
and support us for our knowledge about this. Can you advise us any criteria
or standard related with this problem which can change the thoughts about
coating in our customers.Thank you for your sharing knowledges with us.
