Menu 3. How does the spray unit handle over-spray?
Touch screen input of board dimensions and photocell detection of board position allow the operator to control the spray pattern and coverage of the desired area of the PCB, thus minimizing over-spray. The exhaust system, which is designed to remove solvent vapors and any over-spray from the low-volume spray chamber, maintains straight-line flow in the direction of spray. This configuration combines efficiency of operation with reduced equipment size and cost. Any LPISM which adheres to the edge-contact conveyor is continuously removed by an automatic cleaning system. Back To Top Menu 4. What is the expected LPISM efficiency? Typical spray operation will provide 140 to 150 square feet of a 1 mil thick dry coating per kilogram of LPISM; this easily equals or exceeds the efficiency and economy of other methods of application. Because of the heated spray gun technology, this 1 mil coating will adequately cover much higher traces than a coating produced by other methods, yielding additiona
