| Could someone shares their experience on the causes of 'Open' in the BGA after reflow. | | You must have been in the same meeting I was in earlier today. We are currently having some opens on BGAs. The problem joints are all on the perimeter of

| Surprisingly enough, ever since the addition of an omega wave, we solder those often-troublesome SOT23's just fine and dandy.. anyways, long-term, well be getting a universal GDM which uses positive displacement pumps..currently we're using fuji g

Hello, I am trying to find out your opinion about using soldering bench top soldering robot to solder THT connectors (diffrent). What is your experinces and what is limitation for this system. We can't use wave soldering machine due to the complex

Lead Contamination of wave solder carriers

Electronics Forum | Wed Jan 23 14:09:10 EST 2008 | lmartenson

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

Solder balls - Pb wave soldering

Electronics Forum | Mon Aug 16 16:57:06 EDT 2004 | Shean Dalton

Try to observe the board as it exits the wave, look for solder snapping as the leads finally exit the solder. The surface tension could be such that a "string" of solder stretches away from the wave until it finally breaks. Then, as the string reco

Solder Balls on end of long pins

Electronics Forum | Wed Sep 08 16:44:15 EDT 1999 | Rob Jankowski

I am wave soldering a single sided through hole PCB array with (6) .040" round diameter pins that sit .5" off the PCB, and .080" apart. The problem being experienced is that solderballs are appearing on the end of the pins. I have tried decreasing

hi, NEMI recommends separate solders for reflow sodlering and wave soldering. Reflow soldering- Sn-3.9Ag-0.7Cu Wave sodlering- Sn-0.7CU Wavesoldering- Sn-0.7Ag What will happen if a mixed technolgy PCb board containing both through hole and surface

Delta wave solder

Electronics Forum | Mon Jun 12 07:52:21 EDT 2017 | tch

We have had this issue on our Delta 3 waves and determined that there are small pin holes in the solder pot. We had plates welded to the outside of our solder pot on the lead free wave and this bought us enough time until we could replace the wave, a
