The materials used to manufacture the fixture are the most important. I have used other shops and have had issues with the fixtures not holding up and would start to delaminate. The other issues are how thick the material is that comes in contact with the solder. I have found if you have some pockets that have less than 0.100 mils you might run into trouble. The fixture material will start to degrade and leach solder into the fixture. The fixture house I use also has a way of color coding the fixtures if you want to identify them for a lead free process. This can be important because the residual solder that might be left on the fixture could contaminate the solder pot. One think I like about these guys is if you need a minor change to your fixtures they don't charge you for modifications. I have had some fixture houses want to change me for mistakes they made designing the fixture.
