Phase Change -materiaalit

Olomuotoaan muuttavat Phase change –materiaalit (phase change materials) ovat ohuita, lämpöä ja sähköä johtavia kiinteitä arkkeja tai dispensoitavia komponentteja, jotka alkavat muuttaa muotoaan ns. sulautuen käyttökohteensa rajapinnoille saavutettuaan tietyn lämpötilan. Kun lämpötila alittuu, kiinteytyy materiaali uudestaan levyksi.

Kun käyttökohde, esim. elektroninen laite kuumentuu, tukkii levy sulaessaan pintojen huokoset, jolloin rajapinnalta saadaan poistettua ylimääräinen ilma. Tämä on tärkeää lämmönsiirron kannalta, koska ilman kautta lämpö ei siirry käytännössä lainkaan. Myös pintojen koveruudet ja vääristymät saadaan tasoitettua materiaalin lämpölaajenemisen avulla.

Vaihtoehdot:

Alumiiniarkit phase change -pinnoitteella
Phase change -kalvot
Printattavat ja dispensoitavat komponentit

Edut:

Erittäin alhaiset lämpöresistanssit vähäisen puristustarpeen takia
Silikonittomuus
Helppo asennus
Materiaalikerroksen paksuuden luotettavuus vs. piitahna
Ideaali sotkuisen piitahnan tilalle

Saatavilla:

Arkkeina ja rullissa
Kiss-cut-leikattuna rullissa
Die-cut-muotoon leikattuna
Liimapinnalla tai ilman, osittain tai kokonaan
Eri paksuisilla phase change -pinnoitteilla

SMT

For more than 20 years SMT is the designated specialist for thermal processes with more than 5000 sold units. Know-how easily could be purchased at SMT.

Progress, innovative technology that takes the preservation and protection of resources and the environment into consideration is the philosophy of SMT. Not without reason is SMT the manufacturer of the most energy-saving and easiest to maintain reflow soldering systems in Germany, systems where heat transfer is effected exclusively via a positively-driven convection system.

The portfolio consist from extremely small systems for laboratories and development, via medium-sized units and on down to large systems for the industrial production of electronic modules. Customer-related wishes are always taken into consideration and so flow into our company as part of the continuous improvement process.

Milestones:

Foundation of SMT company by Hans-Günter Ulzhöfer in 1987
First Reflow soldering systems based on IR-radiation technology
First full convection-reflow-soldering systems in 1994
Patent of the revolutionary “Slot Nozzle System” to optimize heat transmission in 1995
Patent of “Double Peak Method” for further optimation of heat transmission especially for difficult PCBs in 1997
Presentation of a new product generation with intention and target „lowest operation costs in power and nitrogen consumption“ and highest availability in 2000
Presentation of the technical unique „ABS process gas cleaning system“ in 2003
Market introduction of the intelligent nitrogen control and measurement system to stabilize the ppm-levels in different operating modes and reduction of operation costs in 2003
Totally new development of the „Power Nozzle Systems“ in 2004 as our answer to higher requirements related to heat transmission in the age of lead-free soldering processes.
In 2007 amendment of the established product range of reflow soldering systems for „frontend area“ by the product range of HTT systems for the „backend area“
April 2008 Opening of the American branch, SMT North America, Inc., in Glen Allen, Richmond, VA
