Subject: Re: bit cleaning while drilling PCBs - drilling plexi

Hi,
Keep in mind when drilling PLEXI, that you build up thermal stress
into the material and can easily break thereof. If critical parts are
machined thermal treatment in owen is requiered. Manufacturers of
plexi can give advise how to do it, also ∗data∗ on drilling/milling.
