Hi Dave, It sounds like you haven�t been shopping for stencil cleaners in awhile. Ultrasonic stencil cleaners start at $12,900, evaporators start at $6,800 and 440-R SMT Detergent is $19.00 per gallon. For $19,719.00 you get everything you need to

Here is an excellent technical explanation of stencil cleaners and their differences (spray, ultrasonic, chemistry type) that I found in the archives: http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=3026&#Message1232

The ultrasonic frequency used in today�s stencil cleaners is usually a 40 kHz �sweep� frequency (also used on semiconductors and other sensitive cleaning applications). This frequency is not low enough to cause stencil damage (the lower the frequen

Well, your wipes are a good first step in removing the bulk of the material, but they do little or nothing to remove the material from the apertures. * It would probably be cheaper to use poly stencils and then throw them away after each use, eh? ;

We are soldering a 8 pin TTL chip on to a CEM1 board that has a hot air level soldering. We use no clean soler paste for the reflow process. Now the customer wants us to clean since he is afraid of flux attracting the dust. We have some SMT LEDs that

Sorry it has taken me so long to respond. I got pulled off onto other projects and was not able to work on the solution to the problen until recently. The solution we have come up with is to change from no-clean flux based solder paste to water sol

What does "maintain it really good" entail? For reference, this is our maintenance procedure for the FX-D: - At the end of an 8hr shift, the solder paste path is purged start-to-finish using Nordson's ValvePurge. The machine's then powered down and

Kerryn, It's the first time I hear someone who needs an automated inspection machine to check the cleanliness of stencils. Why not improve on the cleaning method itself. I use ultrasonic batch cleaner. It takes 3 minutes to clean a stencil, 2 minutes

We're stencil printing a Loctite 3614 Chipbonder adhesive, and we're using BioAct SC-10 presaturated wipes to clean the stencil after printing, without much luck. Operators are not able to remove all adhesive material left in the aperatures, and aft

We just bought a new/used ultrasonic stencil cleaner. The solvent we use is Zestron Vigon SC200. We currently number our stencil frames with sharpies. The Zestron eats the sharpie markings off. I have also tried acrylic paint markers.....eats the pa
