content: I've been searching for a board like the one in this video:by Robotics Mate. Any idea where I can get one or a name for it I can use in a search. A search on 'mounting board' doesn't workAttached is a screen capture. I'm referring to the orange plastic board with the evenly spaced holes.

content: My first thought was that was some flavor of Veroboard, but that is more DIP oriented with through-hole diameter .100" spacing, so that's not it.I'm guessing it's some unique product, but acrylic pegboard (normally used to hang things on your wall) looks quite similar... Pegboard is usually 1" on center holes, not sure how the board you're looking for is designed.https://www.amazon.com/Azar-771322-CLR-Pegboard-1-Sided-Translucent/dp/B008M7RRBI/ref=sr_1_3?keywords=acrylic+pegboard&qid=1656434455&sr=8-3Edit - N/M this is WAY too big. Right idea though - search more for acrylic pegboard and perhaps there is a smaller variant?

content: If you search for “perforated acrylic sheet” or “perforated plastic sheet” you will find many variations on this type of board. There are even prototyping perforated plastic panels offered by Alibaba.https://www.aliexpress.com/item/4001056584942.htmlThere are many materials offered in perforated sheet format, including Acrylic (Perspex), PVC and Polypropylene, as available here…..http://www.harrisonplastic.com/perforatedsheet.htmlFraser

content: Back in the day before project boxes I used hardboard that I lacquered with poly. They used to make this really dense dark board, easy to drill and looked great when the pcb was mounted. Similar to this stuff.Prior to that I built bare circuits on pine offcuts using paper templates.

content: Shock,Clipboards used to be made with a hard material like this.I made speaker adaptors and templates out of them but never foundfull sheets as hard as the clipboards were.Maybe they did what you did to it?Jeff

content: Yeah perhaps it was already finished with something, some hardboard used to have a smooth satin like finish on one side now that I think about it.Fake wood flooring and paneling is probably similar. You can also get used natural wood flooring dirt cheap, bit of a sanding and stain and ideal for project boxes or breadboard/crystal radio/key set bases or soldering tip or tool holders etc.

content: Quote from: Shock on June 29, 2022, 03:34:55 amI use that stuff as a work surface because it's so hard. As a result, it's difficult to drill holes in it.

content: Probably different grades, some of the synthetic boards are almost ceramic like due to the resins or whatever they use to bind it. I remember the stuff I got locally was quite soft for drilling but once lacquered was like walnut. I assume the more lacquer it absorbs the harder it gets.

content: Looks like old style turret tag board to me. Used to come in quite big phenolic sheets, but the only ones I can find now are relatively narrow (~80mm max approx) and ridiculous prices.

content: Those sort of plates go by a variety of names. I learned them as tooling plates or fixture plates. Apparently more modern terms are:Grid platesCheese plates (probably a term used mainly by pathologists and/or Swiss)Here's a grid plate that may interest you:https://www.gobilda.com/1116-series-grid-plate-7-x-11-hole-56-x-88mm/?gclid=EAIaIQobChMI7dCI_uru-AIVj2xvBB2nKQaaEAYYAyABEgICqfD_BwE

content: well i usually find in most of the mil/lab test equipment that i dismantle. also i found it in some mil PCs. the screws i save in a bottle. but the boards I usually throw them away. I would say old ones have a distinctive smell. and for devices older as 2000 i found normaly to be some kind of resin / 3d printed.let me see if i have some pictures of some of them.
