The testing is designed to simulate the worst-case environments the product may experience during assembly, test and life in the end user application. The device is electrically tested to the appropriate catalog specifications. The HMC681LP4E was selected to qualify the 5x5mm QFN surface mount plastic encapsulated family of packages. 1.1 General Description The 32L 5x5mm QFN package uses a copper alloy lead frame. The lead frame is silver plated internally to enable gold wire bonding. The MMIC device is attached to the paddle using conductive epoxy. The device interconnection is performed using 1 mil gold ball bonds. The part is encapsulated using Sumitomo EME G700 or equivalent epoxy encapsulating compound. The leads are finished with 100% Matte Sn plating. The HMC681LP5(E) is a digitally controlled variable gain amplifier which operates from DC to 1 GHz, and can be programmed to provide anywhere from 13.5 dB, to 45 dB of gain, in 0.5 dB steps. The HMC681LP5(E) delivers noise figure of 2.8 dB in its maximum gain state, with output IP3 of up to +36 dBm in any state. This serially controlled digital VGA incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The HMC681LP5(E) is housed in a RoHS compliant 5x5 mm QFN leadless package, and provides the user with a highly integrated solution. This functionality is also available with parallel control as the HMC626LP5(E).

The HMC681LP4E was selected to qualify the 5x5mm QFN surface mount plastic encapsulated family of packages. The results of these tests qualify by similarity all other product using the same package. 3.1.1 Initial Characteristics - 160 HMC681LP4E devices were electrically tested for DC and critical RF parameters. These tests are performed at ambient temperature (+25°C). This test was performed at Hittite. There were no failures in this test. 3.1.2 MSL1 260°C Reflow Preconditioning – 160 devices from 3.1.1 were subjected to 168 hours at 85°C/ 85% RH then a reflow simulation at a peak temperature of 260°C for 3 passes (see Figure 1 for profile). 3.1.3 Temperature Cycle - 80 devices from 3.1.2 were subjected to 500 cycles of non-operating temperature cycling from -65°C to 150°C. This test is performed at Hittite. 3.1.4 Final Electrical Test - 80 devices from 3.1.3 were electrically tested at ambient temperature to DC and critical RF parameters. Any out of specification parameter is considered a failure. This test was performed at Hittite. There were no relevant failures in this test. 3.1.5 Autoclave - 80 devices from 3.1.2 were subjected to 96 hours of humidity (100%), temperature (121°C) and pressure (15 PSIG). This test is performed at Hittite using an Espec environmental chamber. 3.1.6 Final Electrical Test - 80 devices from 3.1.5 were electrically tested at ambient temperature to DC and critical RF parameters. Any out of specification parameter is considered a failure. This test was performed at Hittite within 48 hours after removal from the chamber. There were no relevant failures in this test. Package Type: 32L LP5 Package Style: 32L 5x5mm QFN Package QTR: 10009 Rev: 05 3.2 Package Mechanical Tests 3.2.1 Physical Dimensions - 15 devices were measured to the requirement of the data sheet package outline drawing. These devices need not be electrically functional. Any out of specification parameter is considered a failure. This test is performed at Hittite. There were no failures. 3.2.2 Solderability - 15 devices were subjected to the steam aging and solderability test in accordance with MIL-STD883 Method 2003. These devices need not be electrically functional. This test was performed at Hittite. There were no failures.
