I will try that next. I did speed up the wave pump motor with a larger pully(20% more speed) This was done at the time to try to increase the size of the wave because I had component leeds touching the wave pot as they passed by. Due to the wave high

It does sound like your leads are to long, speeding it up will reduce volume on lead and most will wick up the joint but when slow excess solder is left as long leads will have little flux left to aid drainage when it leaves the wave, thus giving a s

I am glad this thread is still alive as I have a concern. I have just entered the wave soldering business after many years in smt. After wave I am getting icicles or flags on my component leeds. My temps seem to be all with in spec as does my NC flux

Frank-In addition (Dave gave some good scoop) we use a Pyrex Glass board to run through the wave. This is useful as you can see through the board .....you can watch the flux coverage, preheat, and Wave (be it Chip, lamda, or??) as it goes through the

Hi, All these guys have provided you good solid infos already! All I can say is that check your wave solder machine's mechanical set-up too...and the Molten Solder Level in the bath must be maintained at an accurate level/height specially after ded

tell us a your setup parmeters. What is your dwell time? What flux are you using?

Here is some more info with regarding my Wave. 1. PCB .065" thick 2. leed length .20" (.135" protrution) I know this is high but we use many thousands and cutting each is not practical. 3. no clean flux by way of foam fluxer 4. wave machine is a HOL

Hexacon sells the LevChek, it is a special tempered glass plate for checking a wave solder machine. They make different sizes, so you can get one that is close to the maximum width of your wave. They also have grid lines etched on them so you watch i

I did have my solder analyzed and it is clean. The Hollis preheat coils are a bit hard to control but I have measured the board top side and I am getting a temp of 105c just before wave contact. I would like to move to a spray fluxer but I am going

Correct preheating of the assembly is critical. Check with your flux manufacturer regarding the recommended topside pcb temperature as it enters the first wave. It is important that this temperature be achieved without burning the flux on the bottom
