We'll never know if we don't explore things. The same could be said for silver plated, titanium antenna parts... I can see more use for a flexible board. What are your "more" uses for flexible boards? I can't think of any. But a general construction practice (and flexible circuit board qualifies) seems to have more value than some very expensive method of making an antenna. Michael Did you read the article? Making these flexible boards is an arduous process and requires a LOT of capital outlay, so you have to make a LOT of boards or they will be very expensive. -- Jim Pennino |

Maybe true if they're made of mylar or kapton, which most are, but I already posted that very thin FR4 exists, and can be processed in exactly the same way as any other copper clad FR4, and possibly it may even accept laser- printed toner directly on to it, as it will roll just fine through the printer. I don't know where to buy it, but I was given some by a guy who would not have done that it it was particularly expensive or hard to come by. Reread the article, this is NOT how he is making boards. He is basically cutting the conductors from copper foil, laying the foil on the printer, then printing the plastic on top of it. The plastic is whatever the printer prints. -- Jim Pennino |
