Selecting Walter Lemmen Etching Center and COMPACTA Electroplating Systems

Etching Center S and V modular units deliver high-precision wet chemical processing for rigid PCBs, flex circuits, and metal foils down to 50 µm conductor resolution. Rotary spray systems and sealless magnetic drive pumps ensure uniform copper removal across entire panel surfaces.

For reliable through-hole metallization and electroplating of gold, silver, and nickel, Walter Lemmen manufactures COMPACTA MD benchtop units and COMPACTA SPS automated lines with programmable PLC hoists.

Integrating MLP-L Multilayer Vacuum Presses and Process Automation

MLP-L hydraulic vacuum presses (such as the MLP-L 3040 VAC) deliver programmable lamination forces up to 200 kN with precision heated platens. Touch-screen recipe control and proportional hydraulic regulation guarantee void-free bonding for dense rigid-flex multilayers.
