Compact, fast and easy to use plating system specially developed for the professional production and small batch production of PCBs featuring reverse pulse plating.

The LPKF Contac RS and MiniContac RS are through-hole plating systems specially developed for the professional production of prototype and small batch production printed circuit boards, featuring Reverse Pulse Plating and unmatched ease-of-use. The systems are ideal for any rapid PCB prototyping situation, especially small runs and tight work locations. They employ reliable formaldehyde-free Blackhole® Technology for direct metallization.

The Contac RS offers the largest board size capacity of any LPKF plating solution, plating boards as large as 16.9” x 11.4” (430 x 290 mm), as well as a heated tank for chemical tin plating (tin plating is excellent for optimal soldering of through-hole plated circuit boards and oxidation protection). A sink bath is connected via an external water supply for the cleaning step.

The LPKF MiniContac RS handles circuit boards as large as 7.8” x 11.4” (200 x 290 mm). The system is completely closed and needs no external connection.

The LPKF Contac RS and MiniContac RS systems use switchable reverse pulse plating, producing more uniform copper plating for difficult aspect ratios and smaller holes. Reverse pulse plating is also very useful for small holes on high density PCBs and improves production reliability during soldering. Reverse pulse plating uses precisely controlled reverse pulses to remove excess material during the plating process

The through-hole plating process starts with the cleaning of the circuit boards. The PBCs are degreased, then pre-treated, then activated. A galvanic bath adds the copper coat, and after rinsing and cleaning, the boards are ready for soldering. The LPKF Contac RS provides an additional sink bath for rinsing circuit boards, and a bath for chemical tin plating.

Easy Interface

The microprocessor-controlled LPKF MiniContac RS is easy to use, featuring a four-line display with a menu-driven user-interface.

Simple Chemistry

The LPKF MiniContac RS uses only four chemical baths, which can be changed simply and easily when required. The LPKF Contac RS uses only six baths, also easily changed when required. No Chemical knowledge or background is necessary.
