content: Looking for a source of prototype DIY boards. Amazon has lots of them, but they all have plating on them. I want the bare board only, no plating. What are they called, and a source?

content: Quote from: B J on October 04, 2020, 04:45:42 pmDo you mean a base without a copper coating? This is called fiberglass, if I call it correctly in English.But you can buy a blank with a copper foil coating and tear off this foil carefully.

content: The fiberglass material is called "FR-4".They come in different thicknesses and dimensions. Here's an alibaba listing... should lead to other options:https://www.alibaba.com/product-detail/XJEA-1020-1220mm-G10-g11-fr4_60822978935.htmlI found some more listings on aliexpress by searching for "epoxy sheet" - e.g.:https://www.aliexpress.com/item/33060923943.html

content: Quote from: ledtester on October 04, 2020, 05:18:04 pmIs FR-4 the name of the material? After all, this is a set of material characteristics, a certain standard.I do not know for sure it is only a description of the base material or other parameters of the PCB design such as the minimum thickness of the track and the distance between them, etc.

content: I do not want any copper layers, the base material only. I'm looking for the board only, with holes at 0100 inch. I prefer a fiber board, not fiber glass. I have some from years ago and running out, but can't remember where I got it.

content: Thanks all. I have some on the way. Didn't find exactly what I was looking for, but shortly I will be able to build a couple more boards I am getting ready to do. Amazon had some hiding that took awhile to find.

content: Quote from: B J on October 04, 2020, 11:31:03 pmGenerically that's called "perfboard". I used to use it quite a bit but I've since moved on to other techniques. Used to be able to buy it at Radio Shack and Active Electronics, both of which are now gone though.

content: Quote from: B J on October 04, 2020, 04:45:42 pmJust a little pedantic note: a PCB means “printed circuit board”, which perfboard with no copper cladding decidedly does not fall under! :p
