| | Any Comment's about mydata placment reliability (repeatablity) on all types of components. | | we have trouble quantifying just how good it is. | | Is it as good as Mydata Claim ?? | | Please help | We have 4 Mydatas running at this time. | Non vision parts must be mechanically centered which, over time | does not lend itself to placement repeatability. 0603s pose some issues, | specifically, the indexing mechanism of Mydata's magazines must be adjusted | frequently to keep the tape pocket centered. If you plan to place a lot of | passives with a Mydata machine, don't. The HYDRA option gives you the ability to gain some placment speed but doesn't make sense unless you are running product that has a low part mix and is a high runner such a SIMMs/DIMMs. Look at a machine with some form of | "non-contact" centering for passives such as laser (Zevatech) or CCD camera | (Panasonic). | As for fine pitch parts, we have no complaints. Centering repeatability has | been good. (We track placement accuracy daily) BGAs do pose a fairly serious | problem however. The current software does not allow teaching of a "non-full | array" BGA. That is an array that has center or corner balls missing. We | are currently building products with 3 different BGA packages and all are "non-full | array". I could be off base here but it appears that many BGA configurations are NOT full array. | Mydata says they will incorporate this capability into the next software release | due out towards the end of the summer, but they have typically been late with feature | enhancements. | Prototyping and low volume environments are what these machines were built for and | they serve the purpose in that regard. Think hard about what your operation will | be doing in 6-24 months before selecting Mydata.
