MGFC4419G MITSUBISHI SEMICONDUCTOR <GaAs FET> InGaAs HEMT Chip MITSUBISHI ELECTRIC PRELIMINARY Notice : This is not a final specification Some parametric limits are subject to change. TECHNICAL NOTE 1. Characteristics and quality assurance 1.1 Electrical characteristics a. DC characteristics on spec. sheet show the test conditions and values using wafer-prober. DC characteristics are tested 100% devices. b. RF characteristics are tested using the corresponding packaged FET. When more than 80% 0f the samples satisfy the value of RF characteristics on spec. sheet , that wafer is accepted for shipment. 1.2 Quality assurance and reliability a. Mechanical characteristics are tested using corresponding package with sampling test. b. Visual inspection is complied with MITSUBISHI's technical note. c. The electrical characteristics and the quality assurance test are sampling test. And so the shipped chips are contained some sub-standard articles. d. After opening the packing , the quality of chips are influenced with storage conditions. Our recommended storage conditions and period is as follows: Ta=25±3 deg.C MITSUBISHI's packing + Desiccator 6 months Opened packing + Desiccator 2 months In the desiccator , leave the chips in the pack keeping up-side-up and store in a clean and dry enviroment , preferable dry N2. e. Packing quantity Standard : 400 pcs. or 50 pcs. / each waffle pack Custom order : 25~400 pcs. / each waffle pack by 25 pcs. step In case of long storage exceeding 2 months at customer after opening the packing , total quantity of order shall be separated and small unit quantity of each orders shall be custome ordered. In this case , we may prepare special spec. No. for each customer. (ex . -21,-22 ) 1.3 Others The device shall not be returned in the following case. a. Inadequate storage b. Mishandling c. Incorrect die/wire bonding d. RF characteristics failure rate less than 30%. 2. Ordering information The classification with Visual grade & packing quantity is listed in Table.1. Spec.No. Visual Grade Unit quantity for each waffle packe -A01 A -A02 B 400 pcs -A03 C -A11 A -A12 B 25 pcs -A13 C Table.1. Standard specifications as of Jan.'98 (4/4) |
