The machine sees a magazine, but with wrong number. somehow one (maybe more) wire from the magazine bus does not reach slot 3, as the other slots work, there is probably not a short, as the magazine bus work for other slots, the problem is probably i

OK, granted, this is not exactly your hi-tech SMD production but pertains to lead-free so I'll post this anyway: Can anybody share their experiences on lead-free dip soldering of transformer terminals? I have not done any testing myself but have see

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

We had x-ray and optical microscopy analyses done on transformers dip soldered with Sn/Pb, SN100C3 and SN100C4 alloys using temperatures 400�C ... 450 �C, with dip times of 2..4 seconds. We found that SN100C4 is at least as good as Sn/Pb 62/38 and SN

We are implementing a high volume dedicated product line that will be doing lead free selective soldering. There seems to be 3 basic technologies. Wire fed (Panasonic Softbeam or Laser), solder pumps and chimneys (Pillarhouse, SEHO, ERSA, etc) and

There's also microflame which uses a mini gas flame to melt the solder. We tried a number of ways then modified some conveyorised robot cells we bought at auction, using wire feed & an iron head, incorporating veriable tinning & preheat, with point

We need more information about the situation. For instance: * Describe the green residue * Talk about the distribution of the problem, including a single lot or from various lots and over components and component types on the board * Tell us about t
