There are also Process monitoring tools that mount directly to your blades and monitor the paste. Impedance Spectroscopy is the process monitoring theory behind the tool. It works by having good sample data logged that the monitoring tool can compare

If you require several changeovers per shift the quick connect closed loop pump option would be your best bet.You can change between pump and blades within minutes. Hoever if you have several different size pumps a simple pump switch over would be pe

| Anyone knows what is the optimum squeegee angle for screen printers. | | 45 Degrees. The forward velocity creates a downward pressure equal to the vector pressure (equalibrium). This is commonly known as paste "rolling action". Too obtuse an an

200 boards an hour and probably does. Our slow P&P machine keeps us from getting that benefit. But we get to have all the headaches. I think the printer runs on a 286! That's pretty sorry for such an expensive piece of equipment. The stencil frame is
