High performance epoxies such as Nelco's N4000- 13, Isola's FR408 and General Electric's GETEK (similar to Matsushita's MEGTRON) have become essential for boards operating in the higher frequency range. For applications at the highest frequencies material choices are very limited. These materials, tailored for high frequency use, have disadvantages - either with their thermomechanical properties or with their process 410 0$aCircuit World.$nNo. 4 ;$vv. 30. 606 $aElectronic circuits 606 $aMaterials science 608 $aElectronic books. 615 0$aElectronic circuits. 615 0$aMaterials science. 676 $a621.319 676 $a621.3192 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910449978103321 996 $aSubstrate technology$92267355 997 $aUNINA
