So, after 101 checks of my board design, I sent it off for a set from a popular house in Asia. The boards came back looking very nice, but ended-up being $70 of trash. The issue is that everything measured correctly in Fritzing, but the board hole spacing does not match that. So, I’m asking if the error might be on the factory side, or if it may be on the Fritzing side, as I can’t do many of these mistakes. I might also get some credit if it was the board house causing the error.
Here is how to duplicate: I used a string of ten (10) 3.5mm 2P screw terminals from the Core parts. I made 10 and spaced them with 3.5mm grid spacing. In Fritzing, the part holes are wrong (should be 3.5mm, duh), but holes measured less than 0.5mm off, and the actual OAL of terminal blocks came-out right-on at 70mm using the Fritzing ruler.
When the board were made, the holes were 68.6mm center-to-enter at the ends (not 66.9 with part error) and the overall of the silkscreen part outlines were 72mm (not 70mm as Fritzing measured). This is just big enough to make for very poor assembly at best, and are really not acceptable. Can anyone shed light as to why the actual PCB does not match the Fritzing dimensions? Can I prove the error was theirs, or am I stuck with junk boards? Any insight welcome!
