I agree with one of the previous posters that phpbb is a great forum software. Tons of features and it's easy to manage. I also believe that we are very fortunate to have this free forum. I've grumbled under my breath a few times about the load times

Hi, you want something that will not break down, and something not American then. I would look at the Fuji XP-143E (if you are not going bigger than 20mm x 20mm) or the Juki then. Also I would look at what they are predominately using in Turkey, as

I think Sr is right. Miss prints are prolly a result of your tooling moving the board after the camera looks at the fids. It also could be the camera itself hitting the board from warpped board or tooling raising the board up. It may be the camera
