Subject:  [TN] PCB panel design.




Dear sir/madam,
        I am in the process of panel design for the FR-4 double sides 1 oz
PCB,
0.4 mm thickness and 1.475 x 1.087 square inch dimension. This is the first
designing job for me, I'm looking for the information about the V-cut and
perforation requirement. Does anyone can give me some information regarding
the following I will appreciate very much.
        1. The critical requirement for panel designing.
        2. With the 0.4 mm thickness substrate, should I select the v-cut
technic
or perforation technic for depanelling to serve the firm board during
assembly and easy to brake after assembly.
        3. How to calculate the v-cut depth relate to the substrate
thickness.
        Further information that is necessary for panel design please
advise.
        I look forward to hearing from someone.

With best regards,
Noppadol S.
