The ion exchangers have been found in the field of waste water a very large application. The rinse water accumulate on the process baths with the metals. The legislature prescribes a recycling and cleaning of the rinse water. Principle: In the ion exchanger system, the rinse water is continuously circulated. The solids are hold back by a fine filter. Depending of the kind of resin the ions are reversibly or irreversibly caught in the ion exchange resin. After complete loading of the resin, the ion exchanger needs to be regenerated or smelted. The smelting of the resins or the regeneration is carried out by specialist companies. The particular advantage of the System is that the ions are completely removed from dilute rinse water into the reson, where they can be recovered in a concentrated form.
VARIODRILL is a PCB drilling machine for prototypes and small batch production. The demand for operating comfort and high quality has led to an untraditional design which meets the necessary requirements for an ergonomic correct working position.
With integrated frequency transformer A professional brushing machine designed for use in small series production and laboratories. High quality wet-processing brushing machines for PCB production at low price are possible! The proof is the Bungard RBM 300. The smaller sister of our RBM 402 is reduced wherever possible but not at quality, endurance and high precision details.
This machine from the COMPACTA-series was consequently designed to meet the demands of professional direct metallization. It can take boards up to 210 x 300 mm² and has 5 treatment tanks (cleaning - pre-dip - catalyst - intensifyer - reserve tank) and one galvanic plating tank. Two treatment tanks are thermostatically controlled and equipped with a teflon heater. Bath movement on all tanks is performed with DCgear motor. The stroke speed is stepless variable. The galvanic plating tank comes with an integrated air injection and a stepless regulated rectifier. A Volt- and an Amperemeter show the current electric values. Special emphasis was put on a unique rinsing technique. A double cascade rinse and a spray rinse, the latter activated via foot switch and a magnetic valve, are integral parts of the COMPACTA 30. We also offer the COMPACTA as a complete system including chemicals, anodes, anode holders and board holders.
The RLM is a dry film laminator especially made for small companies, schools, research and development departments. All commercial laminates for PCB manufacture and mould-etching technique can be processed. Due to adjustable pressure control and adjustable laminating speed, solder mask application is also possible without problems. The machine is also used in very successfully in other application fields like WAFER MASKING and SMT STENCIL production or METAL WORKING.
The RBM 402 series is the highest highest developed brushing machine in our range. It is ideally suited for professional prototyping or small batch production in modern PCB laboratories. The machines perform double side operation. Upper and lower brushing rollers are adjustable in pressure and have a digital read-out. Oscillation and transport speed are variable. The wet procession system comes together with a powerful squeeze + hot-air dryer. The standard version KF - has a closed loop rinsing system with integrated rinse water tank, filter and pump unit. This saves the user money for fresh water and headaches about how to meet waste water regulations. On request we offer version F with external water supply. The "F" is indicating an integral, automatic filter system. That is urgently recommended in order to comply with German and European waste water pollution directives. These "F" machines are equipped with a 100 m filter tape (5 µm) and a waste water level control. As the tape load of filtered particles increases, the sensor will automatically start the filter transport, so that fresh filter tape is supplied. The last version of the RBM 402 is the BLC model. This is a simple benchtop machine with external water supply and no filter unit.
Based on the same principle of construction as our Compacta 30 series, the Compacta 40 2CU is optimized for higher productivity. You can manufacture boards with a maximum size of 300 x 400 mm2 . This enlargement plus an integral, second plating bath leads to almost 4 times higher daily throughput with only little more space requirements. Based on the COMPACTA-series we also produce machines for other chemical systems. Alternatives for improved surface qualities: Bungard is also experienced in galvanic nickelgold-systems for long lasting, bondable surface quality. Moreover tin-, blackening- or sealbond-systems are available. Contact us for your individual, customized solution.
Powerful spray etching or spray developing machine mainly designed for use in pcb labs. Capacity up to 3m²/h possible (single-sided, positive material).
