Rehm features void free Vacuum Soldering Solutions for solar and semiconductor packaging applications

Rehm Thermal Systems will showcase its newest vacuum soldering technology at this month's Semi Con West and Intersolar exhibitions in San Francisco. Members of Rehm's technical team will be on hand at the booth of American business partner Technica USA (#5757) to explain the numerous advantages available from this enabling technology

Rehm offers void free vacuum soldering solutions for a variety of applications covering a temperature range from 50°C to 450°C which including advanced condensation reflow for lower temperatures up to their latest high temperature VS offerings. On display in booth 5757 at Intersolar will be the VS 160S vacuum soldering system which features void free vacuum soldering at temperatures up to 450C with the use of controlled gasses. Oxidation free and void free interconnections between chip and substrate in packaging applications are just two of the many advantages that the process delivers.


Rehm's VS systems are particularly significant for (CPV) photo voltaic concentrator module assembly processes which require high temperatures and where high power interconnections need to be void free. PV concentrator technology replaces the majority of the semiconductor content of traditional modules with less expensive optics, and thereby reduces costs while promising to boost cell efficiency to far over 25%.

The small, powerful and affordable Rehm VS vacuum soldering systems enable improvements in numerous other high temperature soldering, including formic acid, Microwave Plasma, and 100% hydrogen processes.

VS soldering technology is just one part of a large group of Rehm products that contribute every day to the advancement of photo voltaic manufacturing technology. For instance, RFS and RFS-D Fast Firing Systems offer a range of advanced process features and thermal control that enable PV manufacturers to move their processes to entirely new levels of efficiency and yield. A holistic approach to energy efficiency has resulted in new benchmarks for reduced power consumption and ambient atmosphere influence. Rehm's RFS Fast Firing system measures in at a typical 17KWh, and the RDS Drying system a meager 7KWh. In addition, external cover temperatures are maintained at <35 degrees C .

Rehm's firing furnace boasts a wide process window, better performance, lowest cost of owner ship, and proven high throughput. These benefits are important for PV manufacturers that are looking to advance their productivity and cell efficiency more than ever before.

3M™ Extreme Sealing Tape is a family of single coated, pressure sensitive adhesive tapes designed for difficult sealing applications. The backing on this tape is an ionomer film that is very tough yet flexible and abrasion resistant. The very soft and thick acrylic adhesive has excellent sealing properties and good outdoor durability. This single coated tape is designed to seal over an existing joint, seam, or penetration. The adhesive is designed to adhere well to the ionomer film so that overlapping tape joints can be made while maintaining a strong seal. 3M™ Extreme Sealing Tape - instant sealing that rolls on fast and looks good.
