It sounds like you are asking a question we have been dealing with in the 
US. From my experience I used to optimize my panel size to the individual 
printed circuit board. We would have a large inventory of press plates and 
glass tooling frames to accommodate any panel size we could think of. 
However, we were building process lots where the total customer order would 
add up to thousands of process panels. It was all about saving on materials. 
Since the volume orders have left the US, many of us are all now quick-turn 
and prototype shops. In place of one large order to work on for days we have 
many small orders. I went from as few as 3 setups a day to as high as 25 
setups in a given department for a single shift. Multiple panel sizes were 
killing us with regards to production through-put. When we restricted our 
panel inventory to three sizes our set-up time was greatly reduced. We ended 
up having more waste on the panel but save on setup and throughput. I hope 
this helps.

Subject: [TN] any idea about standart panel application


Dear Technetters,

        I have a question about standart panel application. As you know that 
first step CAM , 2. step panel cutting in pcb production.
sta. pn. appl. is for panel cutting section. I mean we have a few standart 
dimension. there are more than one pcb on every panel.
We adjust places of every pcb at CAM depart before  we put pcb on standart 
panel. We try to use all place of panel minimium lose. That
mean pcbs positions are adjusted for stable dimension. But sometimes we must 
design new dimension panel for special order of pcb. That
mean panel dimension is adjusted for pcb. Both of situation the target is 
get a minimum panel lose and get using max. I request that can you compare
both of them of their advantage and disadvantage
       Best Regards
