5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Hey guys, I ran a couple of profile in our wave solder machine using wave optimizer and this is what i got: Parallelism = 0.0 Immersion Depth = 2.1mm to 2.4mm with varying immersion time from 1.1 sec to 3.1 secs. Contact Length = between 5.0 to 6.0

One other thing you may want to look at is your nitrgen settings and the difussers. If you don't have them correct, you can also see bridging and icicles.

Try: * Prebake * Flux density * Conveyor speed * Upper preheat * Cooling time * Chip wave * Solder temperature You could add immersion depth (1/3 to 2/3 of the board) to convince yourself that it has the least impact of any variable in wave solderin

Il ne pas de quois. Two most important parameters are: * Solder temperature * Dwell time Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering.

I would definitely try a more agressive flux. Are you using a W.S. or No-Clean? And of course check the usual preheat temp flux application dwell time immersion depth

Annular rings are too big, it is acceptable to have shorts on the common conductors. I would be willing to say the "other" supplier may have modified the artwork as well. Good fluxing, preheat and proper immersion depth are key to eliminating short

Check out http://www.solderstar.co.uk/wavePro.html This tool measures all key wave solder information with a single pass. Wave/PCB contact, immersion depths, etc. Also has a reflow pack to allow use on reflow, 9 channels with predictive software. B

1500 lbs) vary by a couple of degrees) were standard. I thought that flux penetration into PTH barrel and solder pot immersion depth and solder pot parallelism would be also critical factors. We are using the ECD WaveRider to measure the implied sold

John, we have waved 0603 packages for a long time, We have also started on 0402. Are you concerned with shorting across the component body or to other components? You should have no problems with these parts in a wave process. A couple of things
