You can stop cleaning after a job when there is no more paste in the apertures. Under wiping should be done with a quality cloth and should leave no paste on the underside of the stencil (assures good contact on the next print and reduces chances of

I agree with Mainteneer on this. Depending on the active components, I would check the datasheets of them. Particular groups of components to pay attention to: microphones, microprocessors, transformers, relays, switches. Washing may be in some cases

5 stencils/day. Not sure of the cost, it is high, but I only use a little each month so it is cheaper than the 50+ gallons I was dumping out each month of the old stuff. Mix it with water and use at room temp (don�t have any eaters).Don�t create any
