fuji feeders | 29 October, 1998

I am currently in the process of rebuilding and maintaining a never-ending supply of tape-feeders for Fuji CPIII and IPII (Fuji and Hover-Davis). I have seen the videos and am not having all that much trouble, but I would like to compare notes with some one and maybe share some things that I have picked up. Any help would be appreciated. Thanks

Re: fuji feeders | 2 November, 1998

Thanks for your reply. I am interested in knowing about maintenance schedules and levels. I'm wondering how to know if I must replace a part. What part? What type of lubrication (for Fuji). Etc. My company is small in terms of number of lines and the amount of feeders we have for each line. Up until recently, we had a " If it ain't broke, don't fix it" attitude towards feeder maintenance. But then, after 6 or 7 years, we had some problems. I started dismantling and cleaning them and putting them back in service. My methods are sometimes less than scientific, but I am getting generally good results. However, I feel,even after all this time, like I am working blind. So what I am trying to find out is this: what do others do? Thanks for any advice you may have.

As far as preventative maintenance here is what I do:

CP machines, follow recommended schedules as specified in FCP maintenance manual. It does not take very long to do a PM. Remember, PM's are 90 % inspection and cleaning. It is possible to over PM equipment! I even run my FCP test pcb to verify calibration and that takes less than 5 minutes.

FIP-3, same as above.

Feeders, I have about 350 CP feeders and 90 IP feeders. I rely heavily on two methods to determin feeder malfunction. 1. Operator training 2. Statistical error processing Here I have the machjine do the work for me. If it reaches "max. nozzle skip" (3) then there is a feeder malfunction (99 % of the time). Then I just de-bug the situation. It's usually 1 feeder causing a problem. Remember your machine should be running at 99.97 % placement reliability. Fuji feedes are very reliable. I have some that have 2000 hours on them and work great (I place about 500,000 0603's per week) Be careful excessive service can cause problems (oops, missing feeder parts). I perfer to monitor the manufacturing process (machines) rather than service hundrerds of feeders which are not in need of repair. Its true, "If its not broken, don't fix it".
