We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to bu

Glenn, i am aware of one unique problem with voc free fluxes. since these fluxes have certain amountb of water content they cause sputtering leading to solder balls & voids problems. Regards Vinesh Gandhi | I require some feed back from any one

Hello everyone, at the Institute for Manufacturing Automation and Production Systems of the University of Erlangen (Germany) one focus of our research activities is the use of lead-free solder alloys for electronics production. In different publicat

Hope some of you out there can help me with this one. I am getting feedback from our test department that they are showing opens on solder joints which have visually good wetting. The touch-up operators confirm that the joint looks good. All they do

i am working with the noclean process and getting white residues on the bottomside of the board probably due to the wave soldering flux.i am using a no-clean solder paste and a noclean wave solder flux.The boards passed the accelerated temperature a

| hi, | i am working towards developing a no-clean process for a customer at contract manufacturing facility. the assemblies have gold fingers on them. these are masked to prevent from any damage to them during reflow soldering. the earlier proces

Due to an foul up on my part, a circuit board ECO snuck up on me and I have a solder paste stencil that doesn't quite match the board. Two pads are off by about half a pad each. Can the solder paste stencil be modified? If so, what is the technique

Thanks for the info. I modified the stencil, ran the boards, and just got a new stencil. Life is good again. Bernie | Due to an foul up on my part, a circuit board ECO snuck up on me and I have a solder paste stencil that doesn't quite match the boa
