We currently are using an older Electrovert Convection 7-Zone reflow oven for our Lead-Free assemblies. It has a maximum per zone Temperature setting of 280 Degrees C. This is causing an issue with one particular customer who has a fairly dense produ

Our company has run into an issue with de-wetting of lead free components. Our profile is dead on with paste manufacturers specs. We have had this issue with both gold immersed, and hot air leveled boards. We have tried three different solder paste m

I have done noting about optimization, except manualy choosing the feeder location of the most common part or two. I do have a program that takes Protel 99SE pick and place files and converts them to the placement file. I haven't done a program for

First, on your reflow temperature comment: The 183*C focus for reflow recipes for tin-lead solder is a falicy. If you held a recipe for tin-lead solder at 183*C peak, it would never reflow. Recipes for tin-lead solder need to be at liquidus plus 20*C

The Optimizer can be run through your wave like a regular board. It measures temps, times and parallelism of your waves in relationship to your board (pot to conveyor). Run the Optimizer till you get you temps, times and are parallel to your waves.

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are

Thanks Real Chunks. We currently have an RPS opus selective solder machine that we plan on keeping. It is configured as a 3-nozzle (!) one-pump (!!) point selective solder machine w/ nitrogen preheat. Custom wet nozzles. We use lead free SN100C sold

Ck, Just to make myself clear I am not at all questioning your observations. What am trying to make clear is that when your wave contact area changes when the PC board or glass plate traveling speed is changed, something is wrong!!! Also an 180Deg
