We have just installed an omega wave to our W/S machine and are tring to W/S some of our bottom side surface mount components. I am still getting skips on some sot 23's. The component lay out meets all IPC 782 guidelines. I have verified these setti

The Electra is Electrovert's top-of-the-line wave solder machine. Just about the best you could get. Conveyor concerns should focus on the condition of the extruded rails. A machine that new should not have a problem, buy worth a look see. Find out i

Sure you can use SPC charting on the wave setup parameters to warn of impending problems. Examples of useful points of analysis are: * Dwell * Temperature * Pot analysis Certainly there's a range of other process controls that could be monitored.

Its more than likely the conveyor is slightly out and needs dropping. You do have a fairly significant contact though so are you sure the Solder pot isnt running too cool for Lead free, needs to be around 275C for good wicking and flow or 250C if lea

Folk's, Been asked / told by my boss to look into our board prepping area for wave soldering and find another way of doing it. Thing's I'm looking at are: PCB Breakout - do you do it before or after wave Connector's that need to be pressed in due to

| | | we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any

It sound you have already discovered to root cause, flux entrapment in the via holes. Short of changing the desing, here are sone suggestions. The main thing is you have to dry out the via holes of the wet flux. Some things to try are: slow down t

Larry, SOTs are a wonderful thing to try and wave solder! They are about as nice as Tant caps. I have found that shadowing is usually the biggest problem assuming that the other wave parameters are good, in your case it seems that they are. Couple

Most machines for lead free have adjustable conveyor angles (4 to 8 degrees). In the good ole days with lead, we typically ran at about 6 degrees. Often we see closer to 4 degrees with lead free. This is very common, and provides longer immersion

I have an alternative way for you guys to clean the chains on your wave solder machine. We currently use Oil Eaters (live bacteria). The bacteria attacks the oil and any other chemical making it easier to clean the chains. The product is environmenta
