BDS-AMN Automatic Impedance Matching Networks

BDISCOM is proud to introduce a new generation of automatic matching network units operating at the standard ISM frequency of 13.56MHz. Designed for industrial and laboratory use, it’s typical application include magnetron sputtering, PECVD deposition, plasma activation, dielectric heating and, laser excitation.

The Model BDS-AMN 750 automatic impedance matching network includes two variable air-gap capacitors and an analog user port that mates with our series BDS-HF RF power generators. The internal DC bias probe enables measurement and display of the bias voltage developed in the plasma discharge.

BDS-AMN Inside              178_bds_amn600

The BDS-AMN functions to continuously transform the complex 13.56MHz plasma load impedance to the 50 ohm (non-reactive) system impedance. The RF circuit’s “L” topology uses high quality variable caps driven by precision servo motors. Typical tuning time is less than 2 seconds. Using the BDS-HF control panel (located on the RF generator), the user can program and select a wide range of tuning position presets. Independent control and preset operation is possible using 0>10VDC input voltages.
