Oshpark is very good, with 3 board per order for the price of 5 dollars per square inch.? I should point out that the board set I saw would be rather expensive.Their boards are purple, and ENIG (gold plated)The typical Chinese made boards may have a size limitation for lowest cost, and the lowest price will be for HASL (Hot Air Solder Leveled) boards.? On the other hand, a 100 mm square board can be had for 4.90, and that's for 10 of them.? Shipping with DHL is likely 20 to 25 dollars, but that price range covers 5 different boards, all 100 mm in size or less.Using Chinese made boards will require a different physical design.HarveyOn 12/31/2020 6:33 PM, Michael W.
