Is there any standard size in Custom PCB Manufacturing? - Electrical Engineering Stack Exchange

i have no experience of dealing pcb manufacturers except time once used pcbway's service. know if there standard pcb board sizes 1 needs create when getting custom pcb made?

my basic idea not incur cost loss of material pcb manufacturer faces. example, let's use board of 10*10 inch manufacture , submit custom board request dimension of 7*7 inch, increase cost of pcb?

sometimes pcb makers have per-panel price. tell size using..or more importantly, area have work with-- usable area (not panel size) @ least 10" x 16", maybe 10.5" x 16.5" or bit more. small panel. large production believe larger panels more typical. typically phenolic single sided boards use larger panel sizes. this reference lists typical standard pcb panel sizes follows:

panel borders (maybe 0.5" on each side) take away area.

it not particularly important unless pcbs (or self-panelized pcbs) getting size few panel- materials not biggest part of pcb cost in prototype volumes despite being charged per square cm or inch. if pcb or panel approaching or exceeding letter-size or a4 sheet , quantities more hundreds (of size, thousands of panelized boards) might worth worrying about.

when order loose boards don't have pay router kerf , tooling strips either pcb area (well, it's not figured directly costs) or shipping mass, costs incurred later.

it might interesting play online calculators many pcb makers have , see if panelization figures calculations. expect cost per square inch not follow straight line size gets bigger. keep in mind though getting large defect-free areas gets more expensive area increases large panel (without x-outs permitted) may more expensive per square inch smaller panel. may not important if technology level low, multilayer boards fine pitch , tiny holes not negligible. online quotes not final quote in such cases, , come adjusted quote (hint: never lower).
