If we were talking about a single board problem, we�d be thinking about the laminate, but since you imply the problem is broad-based across multiple assemblies, consider the following machine parameters: * Crank-up preheat time / temperature to driv

I think your solder mask is a partial cause of your solder balling. Additionally, adjusting some machine set-up parameters may also help. 1 If we were talking about a single assembly problem, we�d be thinking about the laminate, but since you say t

As Wolfgang says: Conveyor speed may be too high. Excuse me for not stripping-out my repetition from your list, but other machine adjustments to consider are: * Using more efficient [higher specific gravity] flux. [Got it!!!] * Adjusting wave shape

Good answer slthomas! This has got to be the biggest misconception out there. To perform SPC on a wave process you must first perfrom DOE to determine the critical parameters and or control limits. For example you will need temp reading devices tha

Revelation Industries has an Electrovert MPK1-24774. The manual lacks sufficient information to troubleshoot and fix this problem: Reference: Minipack 300 Wavesoldering System 1986 edition, pg, 18, fluxer, Threshold adjustment. After completin

A Customer has asked me about a chart that allows for temperature compensation when measuring specific gravity in a wave solder machine. Anyone know of any temp. conv. chart? Thanks

Bruce, Using a foam fluxer with no-clean flux is a very touchy situation. It is imperative that the specific gravity of any flux be maintained within the manufacturers recommendations. If it is not, you will get icicles and bridging. Maintaining the

Hi This will vary between flux used your flux supplier should be able to furnish with these easily.

Jacki - using the airknife is not going to help your bridging problems. You will need to keep an eye on your specific gravity of your flux. You may need to thin the flux that you are using. Also the ultimate fix is a vibra wave. I would almost be tha
