Hi, There are many companies shifting lead free solder wave. My question is can anyone give me idea if we can still use our old solder wave machine for lead free eventhough the solder pot is stainless steel 316L? Our solder bath has titanium nozzl

Dear all, We observed visible micro crack at top side of solder fillet during lead free wave solder process. We did not see any visible micro crack at bottom side, and it always located at joints of transformer. Any input be much appreciated. Best

Hello Could somebody inform us about real consumption of lead free solder alloy SN100C on your wave solder process. We do not use some antiaxidant and had had alloy consumption about 1 kg per hour. What is your experiance? All sugestion will be well

You have provided very little information. Two similar possibilites come to mind: poor pad solderability protection and old boards. POOR SOLDERABILITY PROTECTION: Maybe the nickel plating under the gold is oxidized, contaminated, or otherwise very

No clean solder paste. One further observation ... the parts have a metal shell and are 'floating' high on the paste. Though there is wetting on the metal shell, it doesn't seem to sink as far as it should and this could be lifting the soldertails f

Hi guy Does anyone have experiance with printing problem between solder paste water soluble 62/36/2 and gold plating PCB? I do have problem about insufficient solder after printing although I used the same printing parameter as when I print with ano

Yes, we use solder paste,solder bar and solder wire from different manufactureres for 1PCB assembly. And, what JAX said, we never mixed solder paste from different manufactures and used.

Will the flux residue from solder paste A come into contact with flux from solder paste B? If so you better do some tests. There is always a possibility of a bad reaction between 2 fluxes. You need to test to make sure. Jerry

Thanks, I do observed more solder paste terms of percentage in 0.06mm stencil than in 0.08mm stencil.

So, your scenario is: * Lead Free Solder Paste * Lead Free Reflow Profile * RoHS Components * Non-RoHS (Sn-Pb HASL plated)PCB If that's the case, you should be just fine running your Lead-Free process. There is literature on the topic of lead
