I wouldn't recommend a metal squeegee, because if you can't wipe the step-etched area completely clean (that's the problem with metal) you'll have problems with the definition of the fine-pitch (it may stick in the holes). Best is a 70 Shore polyuret

You want to use a rubber squeegee with as high as a durometer as you can get away with, order two or three sets of blades starting with the softest and then progress up the the hardest, the reasoning behind this is the softer squeegees will wear out

Our company has had one of these machines and it worked ok. It is my understanding that the upgrade to a 575 allowed it to go down to 15mil pitch. Although I have never tried it. I would call their North Carolina office and ask to speak with Rick

How about someone on a drum like they used to have in the bowels of a ship to control the speed of the unfortinuate ones that were rowing. The beat could be increased to speed up production or slowed down to adjust for a bottleneck. We had a manage

Be careful on how you go about this. Some older wave chains will have anywhere from a bit to lot of lead embedded into the grease. Ive had best luck sending it out to a shop that can hot tank them. Costs about $25 and it comes back all clean and lube

I made a small bean bag from 100% cotton filled with rice, to hold down small resistors that wanted to tilt over solder wave. It worked fairly well as long as I didn't try to take it off the components to soon, as sometimes they would want to stick

I have used these bean bags for several years now. They work great for holding down odd formed components during the wave process. I use the cotton ESD smock material and cut out what ever size I need. Works Great!.

I dont know what kind of screener you use but my 1st impression is that the board and stencil are separating too fast,the paste doesn't have enough surface tension to stay on the board, you're tearing the paste off the board. If you can, slow down th

Hi Again, As I was thinking about this, I remembered another unconventional way that I was told about from one of the starters of this technology. Now I don't think anyone would use this technique anymore, yet here it is: Press Cutting and Pushing

If your looking for a small footprint at lower cost a Zevetech 575 or Quad 4c should do a good job for you. If your boards get more complicated or you go down to fine pitch, 402's, BGA, you may need to look at a newer technology. We just went throug
