Hi All, after many years of talking about it we WILL be setting up a lead free line. What alloys and products would you recommend. We are seeting up a new wave machine here soon and could us some input.thanks

The LF wave solder solder alloy that marketing-types of other LF wave solder alloys compare themselves to is Nihon Superior SN100C

Grant, Why don't you try a water-base flux which is No-clean, VOC-free also? I have tried the 270WR flux from AIM with good results even on lead-free process. My $0.02, George

Hi, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le

Hello everybody, We are in the process of implementing NC process on the wave solder. We have a Sonotek XL fluxing system. Any ideas out there? Solder used: SN100C Flux options so far: 264-5 flux, 270WR VOC-free 9both from AIM solder) The flux ch

Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

unfortunately you need to increase your maintenance on these ovens, I would doubt if anything is wrong with your equipment. the Flux accumulation is normal, and you are putting alot of flux through those ovens. Just clean more often Russ

Probably because the flux manufacturers have deemed it necessary to increase flux volume by 20 - 25% compared to Leaded this is why more is being left over. Really not convinced of this increase in volume actually does anything. Black residue will be

With high volume production, this can happen. The flux is vaporizing in the heating zones, and is condensing in the cooling zones. Depending on the machine, cooling can act differently on different machines. Less cooling may reduce this problem.
