LPKF Laser & Electronics North America Circuit Board Milling Machine for Training Applications ProtoMat E34 / E44

The LPKF ProtoMat E-Series rapid PCB milling systems are a low-cost introduction to the world of professional in-house printed circuit board prototyping. They will structure single or double-sided circuit boards, drill holes for through-plating and cut individual boards from the base material offering a 9" x 12" working area. The LPKF ProtoMat E34 includes a 30,000 rpm variable spindle, and the E44 provides a variable spindle with up to 40,000 rpm. The maximum travel speed is up to 100 mm per second. For manual tool change and cut depth control, both models include precision height adjustment by micrometer screw. With mechanical resolution of less than 1 μm, repeat accuracy of ± 5 μm, and precision of ± 20 μm for double sided alignment, these compact benchtop ProtoMat circuit board plotters enable rapid prototype PCB milling with traces as small as 4 mil (0.1mm) and spacing of 8 mil (0.2mm) or larger. Registry System and Camera In addition to increased positioning accuracy with double-sided printed circuit boards, an automated fiducial alignment camera is provided on the ProtoMat E44 model. The camera measuring function enables a desired cut width to be set more easily with the ProtoMat E44. Both models allow for set pin registry for processing double-sided printed circuit boards. They hold the processed circuit boards securely in position, even after the boards are turned over for structuring the second side. With the E44, the camera improves alignment positioning as it detects fiducials or geometric structures and orients the structuring process accordingly within the software.
