MA4FCP305 Silicon Flip Chip PIN Diode 1269 Outline Drawing Features n n n n n n n V 3.00 Low Series Resistance : 1.7 Ω Low Capacitance : 50 fF Fast Switching Speed : 20 nS Silicon Nitride Passivation Polyimide Scratch Protection Designed for Automated Pick and Place Insertion Rugged by Design Top View A B F Description Side View D M/A-COM’s MA4FCP Series consists of Silicon Flip Chip PIN diodes fabricated with M/A-COM’s patented HMIC process. This diode is fabricated on epitaxial wafers using a process designed for repeatable electrical characteristics and extremely low parasitics. This diode is fully passivated with Silicon Nitride and has an additional layer of Polyimide for scratch protection. These protective coatings prevent damage to the junction during automated or manual handling. This flip chip configuration is suitable for pick and place insertion. E D C Bottom View Applications The small 0315 outline and low 0.085 pS RC product, make the device useful for multi-throw switch and switched phase shifter circuits requiring < 20 nS switching speeds up to 18 GHz operating frequency.

Assembly Considerations Mounting Techniques The following precautions should be observed for successful assembly of the die. These devices were designed for insertion onto hard or soft substrates with the junction side down. They can be mounted with electrically conductive epoxy or with a low temperature solder preform. The die can also be assembled with the junction side up, and wire or ribbon bonds made to the pads. Cleanliness These chips should be handled in a clean environment. Do not attempt to clean die after installation. ESD These devices very susceptible to ESD and are rated Class 0 (0-199 V) per HBM MIL-STD-883, method 3015.7 [C = 100 pF ±10%, R = 1.5k Ω ±1%]. Even though tested die pass 100 V ESD, they must be handled in a static-free environment General Handling The protective polymer coating on the active areas of these devices provides scratch protection, particularly for the metal airbridge that contacts the anode. Die can be handled with tweezers or vacuum pickups and are suitable for use with automatic pick-and-place equipment. Solder Die Attach Using Electrically Conductive Ag Epoxy and Solder These chips are designed to be inserted onto hard or soft substrates with the junction side down. They should be mounted onto silkscreened circuits using Electrically Conductive Ag Epoxy, approximately 1-2 mils in thickness and cured at approximately 90 °C to 150 °C per manufacturer’s schedule . For extended cure times >30 minutes, temperatures must be below 200 °C. Sn Rich Solders are not recommended due to the Tungsten Metallization scheme beneath the gold contacts. Indalloy or 80 Au/20 Sn Solders are acceptable. Maximum soldering temperature must be <300 °C for <10 sec. 2 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
