(power dissipation calculated using + 25 c temperature rise.) 6. printed circuit board materials : type CWR11 is compatible with commonly used printed circuit board materials (alumina substrates, fr4, fr5, g10, ptfe-fluorocarbon and porcelanized steel). 7. attachment: 7.1 solder paste: the recommended thickness of the solder paste after application is .007" .001" [.178mm .025mm]. care should be exercised in selecting the solder paste. the metal purity should be as high as practical. the flux (in the paste) must be active enough to remove the oxides formed on the metallization prior to the exposure to soldering heat. in practice this can be aided by extending the solder preheat time at temperatures below the liquidous state of the solder. 7.2 soldering: capacitors can be attached by conventional soldering techniques - vapor phase, infrared reflow, wave soldering and hot plate methods. the soldering profile chart shows maximum recommended time/temperature conditions for soldering. attachment with a soldering iron is not recommended due to the difficulty of controlling temperature and time at temperature. 8. cleaning (flux removal) after soldering: the CWR11 is compatible with all commonly used solvents such as tes, tms, prelete, chlorethane, terpene and aqueous cleaning media. however, cfc/ods products are not used in the production of these devices and are not recommended. solvents containing methylene chloride or other epoxy solvents should be avoided since these will attack the epoxy encapsulation material. 8.1 when using ultrasonic cleaning, the board may resonate if the output power is too high. this vibration can cause cracking or a decrease in the adherence of the termination. do not exceed 9w/l @ 40khz for 2 minutes.
