| I am fairly new to the SMT game and I am getting conflicting answers to the following. Maybe someone can help me! When printing, one person is telling me that the stencil should be wiped completely clean of all paste because the quality of the

Dave, Ceramic sheets of that size are not always flat and as a result will sometimes crack when clamped along the full edge. Point clamping will hold the substrate secure for placement. If you are not processing in a pallet make sure that you have

I am curious how you measure your printed paste thickness. We are considering doing the same. As it is now we assure we have squeegee pressure and speed controlled, have not actually measure the printed paste thickness.

How do you assure you "have squeegee pressure and speed controlled"? Search the fine SMTnet Archives for background on measuring paste thickness.

Process control for Photonic soldering is based on the actual temperature of the component being reworked. If the desired temperature of the component for your process is 200C then that is the process temperature programmed. This is achieved by a cl

Nordson has a viscosity control system and a laser fan width control option. We use the viscosity control system on our machine. Basically it heats the material to a set temp. The laser fan width measures the spray pattern width with a laser and a

Know the feeling about Cabletron as we have worked with them in New England for several years. Although management has been the problem I do feel it is not the fault of the engineers and production workers. Keep in mind they have had to deal with t
