> We are requiring a lot 30x30mm 5 - Layer multilayers with ca 30
> embedded resistors.
>
>
> There are following questions:
>
> R values from 68+/- n % Ohm to 10 kOhm+/- n %
>
> Tolerances:n= +/- 1% bis +/- 5% depends of application and nominal
> value. Lasertrimming ?
>
> One resistor on top-layer is to be trimmed under functional test.
> Which kind of laser is necessary for trimming? Is there any service?
>
> Is Rigid flex multilayer as an option possible?
>
> Are there any manufacturers of pcbs, who have experiences in tjis matter?
