NVOC moisture cure conformal coating now comes in high viscosity, gel and aerosol versions. High viscosity is for thicker coating or manual application (brush, dip and selective spray). Gel is a single part, thixotropic material designed for glob-top applications where the coating should not flow once applied. Cures at room or elevated temperatures upon exposure to atmospheric moisture and incorporates a UV trace to aid inspection. Aerosol uses standard NVOC coating for manual application. Are based on polyurethane technology and are VOC-free.

SN100C P600 D4 is a halogen-free, no-clean, Pb-free solder paste that contains no fluorine, chlorine, bromine or iodine. Is said to be high reliability, for high-density assembly with stable printability; reflows easily with good wetting and minimum incidence of mid-chip balling, and low residue. Can be reflowed with profiles similar to SAC 305 and SAC 405 with 240°C peak.

Circuit frames for PCB repair can be custom laser engraved to match the pads or trace areas requiring repair. The patterns on the frames can accommodate spaces/traces down to 0.025 mm. For SnPb or Pb-free processes. The cutouts replace elements on 1 oz. copper PCBs. Custom patterns can be laser-machined with lot sizes as low as one in a few business days.
