Band width relates to conveyor speed to achive a 2 second contact time for Sn/Pb wave soldering. A typical conveyor speed is 150cm/min with a band width (contact band width between PCB and solder) of 5cm. Now for Pb-Free wave soldering a longer conta

Hi, what is minimal time for fluxer to prepare for fluxing another frame ? Is it possible to run through fluxer frame after frame without any spacing between them ? Thanks for any comments, Andrzej

Just change the flux. I have had bad experience with IF2005

Hi, Does any body have the experience with wave soldering a "Gold" plated PCB with SMD assembled on it? I`m experiencing massive bridging,icicles,Shadowing & Skipping. The present soldering angle is 6 deg:,pre heating rate is 2 deg/sec , Dwell time

Hi, What would be the standard band width for Pb-free soldering? As per my knowledge this should be 3cm to 6cm. What is best?

I have waved gold (ENIG) boards. That's a pretty hot pot at 260C, wow. I have used 245C with good results. All other parameters look OK a glance. Well, PCB temp looks a little hot too at 130C before pot. 90-100C is typical for most No-Clean flux. At

Does anyone have any experience with setting up a nitrogen supply system to a wave solder machine that is equiped for it? Does the nitrogen need to be room temp or higher? Does it make a big difference with bridging or solder quality? We bought a use

We dont have the debridging knife. I had one on an old Hollis machine I had once. It was totally worthless. I am setting up the nitrogen today. I will let you know how its goes. We are using a water based no-clean. The nitrogen will probably make a

We are running an RMA flux (Kester 1515). Changing the angle didn't help any so we're back at 6 degrees and placing an order for the lambda nozzle changeover. Are you currently running the debridging knife?
