PCB rapid prototyping machine ProtoMat E34 / E44

The E series LPKF ProtoMats 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. The LPKF ProtoMat E34 has a 30 000 rpm spindle, and the E44 even reaches up to 40 000 rpm. The maximum travel speed is up to 100 mm per second. For manual tool change both possess a collet with a precise height adjustment by micrometer screw. With a resolution of less than 1 μm, a repeat accuracy of ± 5 μm, and a precision of ± 20 μm in the fitting hole system, the small ProtoMat circuit board plotters are more than able to meet the demands of milling single- and double-sided printed circuit boards. Registry System and Camera In addition to increased positioning accuracy with double-sided printed circuit boards, the camera with its measuring function enables milled slots to be set more easily for the ProtoMat E44. After the measuring process, the machine software helps the user arrive at the optimum setting. Registry systems are indispensable 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, a camera helps with positioning: It detects fiducials or geometric structures and orients the structuring process accordingly.
