NC265LR alcohol-based no-clean liquid flux is said to offer low residues and excellent wetting for Pbfree and SnPb wave soldering applications. Reportedly offers faster wetting for SN100C and SAC alloys and is compatible with a range of alloys. Reduces preventative maintenance requirements for spray fluxing applications. Has a 1-year shelf life when stored at room temperature and comes in a variety of packaging. Passes SIR per IPC-TM-650 method 2.6.3.7.

Fine Pitch Bump Adapters accommodate boards with pitches down to 0.40 mm. Permit use of higher pitch devices on smaller pitch boards. Adapter tops have landing pads that can be designed to accept any device on any pitch, and settle into fine pitch footprints, including TSSOP and QFP. Adapter bottom has raised connection pads up to 0.010" that provide easy mounting to the target board. Are 0.062" thick FR4 or Rogers 370 HR, with 1oz. copper traces on both sides. Non-solder mask-defined pads are finished with ENIG. Apparatus can operate up to 221°F for FR4 and 266°F for Pb-free. Are available in tape and reel for high-speed SMT assembly; can be manufactured for RoHS compliance. Standard line and trace spacing down to 0.003" can be used. Are available in panelized form, as adapters only, or as turnkey solutions with devices mounted.

Keratherm U 90 silicone-free thermal interface material has a light tack adhesive to provide high thermal conductivity where contamination threats prevent the use of silicone-based thermal pads; permits easy positioning between components and heat sinks. Is a ceramic-filled polyurethane film with a thermal conductivity of 6.0 W/mK and thermal impedance of 0.05 Kin2/W. Is available in thicknesses of 0.125 mm, 0.225 mm and 0.325 mm. Keratherm U 80 provides 1.8 W/mK of thermal conductivity and 0.11 Kin2/W of thermal impedance; is 0.175 mm and 0.325 mm thick. Typical applications include medical devices, laser equipment, LED lighting, solar energy, disk drives and automotive electronics. Both are available on roll stock or custom shaped pads.
