73 Microwave Techniques for Hybrid Assembly M-pulse Microwave offers chip components which are intended for microwave hybrid assembly. These chip components are supplied in waffle or gel packages that must be opened with care. It is recommended that a vacuum pickup be used for removing the chip component from the waffle package. CAUTION: The vacuum needle must be sufficiently small to avoid possible passage of the chip into the needle. If a vacuum pickup is not available, the die can be picked up by using very sharp tweezers or a sharpened wooden stick dipped in alcohol. For higher than ambient room temperatures the vacuum pickup or tweezers is recommended. Die Attachment The recommended method for attaching chip components for high reliability and high power devices is with a eutectic solder preform such as Au/Sn (80%/20%) in a reducing atmosphere (N 2 +H 2 Forming gas). For some applications, such as experimental work or heat sensitive devices such as Tunnel or Back diodes, the recommended die attachment medium is EPO-TEK H31D Single Component from Epoxy Technologies Inc., or equivalent. Eutectic Preform Die Attachment Place the substrate on a heater strip, a hot plate, or use other means that will provide the necessary heat for the required time. For Au/Sn (80%/20%) the temperature and time to be applied to the chip component should be 300 C for 5 seconds. If other preforms such as Au/Ge (88%/12%), the temperature and time may have to be arrived at by experimentation, or by following the vendor s recommended schedule. When the preform has melted, place the chip component on top of the melted preform and lightly scrub to assure solder flow onto the chip backing. Remove the substrate from the heat source as soon as the die attachment has been completed. Extended exposure to extremes in temperature versus time may cause component degradation or failure. Conductive Epoxy Die Attachment Place a small amount of conductive epoxy (EPO-TEK H31D) onto the substrate where the chip component is to be attached. The exact amount of epoxy to be used may be determined by experimantation. Place the chip component on the epoxy and press the chip flat onto the substrate. This will result in some of the epoxy oozing out on the sides of the chip. This is acceptable providing the epoxy does not creep up the side of the chip, contaminate the face of the chip and interfere with the junction contacts. Bake the substrate assembly in a oven at 150 C for 1 hour or any other curing schedule that does t exceed the storage temperature limit of the chip or component.
