I believe the number 4 corresponds to the number of individual PCBs and the number 1 is for one panel.

  1. Is this the way panelized PCBs are commonly referenced? With an asterisk mark?
  2. What does the "-up" mean in Panel-up?
  3. Is there a more common way when to refer to quantities and descriptions of panelized PCBs?

Here is a link to where I saw the term used.

  • \$\begingroup\$ 4*1 probably means the panel is laid out as 4 PCB's wide by 1 high. Think it would probably be better written as 4 x 1. I think Panel-up is just a bad Chinese to English translation - as is Panelled up. \$\endgroup\$ – Tom Carpenter May 19 '15 at 16:41

    \$\begingroup\$ "4*1" stand for "four by one". I.e. 4 columns, 1 row. \$\endgroup\$ – Eugene Sh. May 19 '15 at 16:41

"4*1" is already covered in the comments: an two-dimensional array of 4 boards by 1 board.

"panel-up" is likely a neologism derived from "n-up", which is a method of arranging multiple smaller images of pages on a single printed page which panelization imitates.
