No mystery there... The balls are reflowed by conduction of heat from the package itself and the backside preheater just as in any other rework machine. The laser is just another method of precisely heating the entire package. The advantage is overa

You can using Ersa IR550A Rework System. The unit was NOT using any hot air process. IR550A Rework System is worldwide the only system with a genuine closed loop control system. Which employs the current temperature at the component in order to regul

Q1. Is it enough to use only water while cleaning or is it necessary to use any additional chemistries and/or saponifiers as well? A1. It depends on: * Flux residues that you're cleaning * Standoff of the components * Cleaning technology [we've neve

We need some opinions about a situation that is causing problems in our process. The pcb's in question are .125 thick with a HASL finish. The boards are coming in with a large amount of solder trapped inside the via holes. Sometimes this solder is ac

On solder in vias: It looks like the via are not solder masked well and pick-up solder either: * Solder coating ... OR * During leveling It's possible that the design specifies openings in the solder mask for these via. On solder in the unsupporte

We currently have agilis feeders and TM8 magazines for our Mydata machines. Our operators and set up people seem to dis-like the agilis feeders. When you set up a reel that already has the overlay tape peeled free from the carrier it gets in the way

Ya know, funny things, them thar agilis feeders. I remember them at the APEX 2004 show, I could'nt even get the dam tape started on them (really hung over from the night before, but I'm SURE that was NOT the problem). Mydata's big selling point was t

Hi, Yes, when we load new reels we cut off the end of the tape, just long enough so we can make sure the whole tape will feed out the back of the machine as it starts to feed. We have the Agillis TM1218 feeders, and they do have problmes with the

I think with any feeder your going to loose parts. After running the five most popular pick and place machines all I can say is, TAPE. Have your operators tape the reel after they remove it from the feeder. It coasts more in ESD tape and it�s a pain

Hi, We also had a lot of problems with tant's on the Agilis feeders, but MYDATA have a feeder that can be adjusted, and it helped a bit, however we changed the machine to a larger version, that went from a HYDRA camera to a line scan camera, and all
