What size panels for chain oven | 23 July, 2022

Is there are reason for going for larger (or smaller) boards when designing panels for use with a chain conveyor oven? My panels range from 0.6mm 2 layer (for touch with hatched ground) to 1.6mm 4 layer. I'm planning to go for smaller panels to reduce the chance of sagging but I'm not sure what sizes are okay. The oven is an Essemtec RO300fc-c. The 0.6 mm board only has a few components on it as most is a touch sensor. The other boards can be thicker than 1.6 mm if it helps. I'm planning to use routing for the panels with mouse bites not v scoring but open to either if it's a good idea.

I generally do not design an array larger than 10" x 12".

Other than just thermal mass, the one issue to watch with extra length is if the array is so large that it spans multiple heat zones at the same time.

We have panels that are up to 48" long, and so they span 3 to 4 zones at a time and it can play havoc with the recipe.

10x6 to 12x8 is ideal for most equipment. Too small panel is not good too for handling by humans and machines. 1.6mm you can use as and depanel on the router. 0.6mm you might need to run on SMT carrier, if you see warping.
