To reduce surface tension of the solder wave, and to achieve the highest quality soldering results, nitrogen is provided to the solder bath and solder pump unit. The unique fast remove pump system designed by the company, enables maintenance personnel to access the pump within minutes. Using the special tool, the pump head is simply turned and easily lifted out of the bath while still secured in the maintenance. Furthermore, the solder bath and pump in the system are made of Titanium, making the machine suitable for both lead and lead free production environments. All SPA-NC selective soldering machines include the Photo Editor, a Windows based software program. Utilizing a point & click” feature, soldering programs are easily created within minutes. Programming the system is intuitive and easy. A scanned image of a bare PCB is all that is needed. Once the PCB is scanned, it is loaded into the editor, and appropriately scaled. For each flux and each solder point, the operator would use the mouse to point and click on the image to teach the soldering locations. The software automatically calculates the correct X and Y value. Because the operator is looking at the PCB image when creating the program, the operator can see all neighboring components to optimize the program and select the appropriate nozzle. This negates the requirement for expensive teach cameras. The system utilizes an CNC controller. The controller is a black/white touch screen with I/O capabilities. The primary function is machine calibration, turning on/off the N2 supply, turning on/off the solder pot, etc., and is the interface for the solder program when imported from the offline editor with FTP Network connection.
