RF Bypass, DC Blocking, Filters, Submounts GHz SINGLE LAYER CERAMIC CHIP CAPACITORS (SLCC) USMK35-040-2 PRODUCT DESCRIPTION AND SHORT APPLICATION NOTE US Microwaves USMK35-040-2 series SLCC - single layer ceramic chip capacitors - are available from low to very High capacitance values, with low inductance, high Q for RF, microwave & millimeter wave, by-pass and D.C. blocking applications. Temperature Coefficient is (TC) = +10% -95% maximum change (non-linear). Dielectric Constant (K) = 35. Capacitance values from 0.1pF to 12pF. Standard electrode metallization is Gold over Nickel compatible with epoxy, AuGe, AuSn die attaching and thermal compression or ultrasonic wire bonding. Gold over platinum is available on special request with custom designs. Custom designs that match 50 ohm line widths of the capacitors with various dielectrics K or different die sizes L or W are available. Capacitors kits are also available: CERAMIC CHIP CAPACITORS LAB-Kit. TECHNOLOGY DESCRIPTION: SEMICONDUCTOR-THIN FILM MANUFACTURING All thin film microwave products are manufactured using advanced semiconductors and thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. US Microwaves employs proprietary thin film technologies for deposition of a wide range of resistive films with sheet resistance films from 1ohm/sq to 10,000ohms/sq. All US Microwaves products are available in die form and are ideal for high reliability hybrid and multi chip module applications.

Gold over platinum is available on special request with custom designs. All US Microwaves products are available in die form. Typical delivery for die products is 2-3 weeks ARO. For Custom designs, delivery is 3-4 weeks ARO. Certain items may be available from stock. Inventory is periodically updated. All devices for chip and wire applications are 100% tested, visual inspected and shipped in waffle packs (WP). For high volume automated assembly, ceramic chip capacitors are supplied as 4" wafers 100% tested, inked and diced on expanded film frame (FF). SLCC DIE LAYOUT / MECHANICAL SPECIFICATIONS GHz SINGLE LAYER CERAMIC CHIP CAPACITORS (SLCC) USMK35-040-2 SLCC CHIP MOUNT GHz SINGLE LAYER CERAMIC CHIP CAPACITORS (SLCC) USMK35-040-2 ceramic chip capacitor mount SLCC ASSEMBLY PROCESS - SHORT APPLICATION NOTE US Microwaves ceramic chip capacitors are designed for thermosonic GOLD wire bonding and AuGe, AuSn or conductive silver epoxy die attach. In general, after die attach, prior to wire bonding operation an oxygen RF plasma clean operation is recommended. IMPORTANT NOTE: Aluminum wire should NOT be used with gold pads due to potential reliability problem known as purple plague. Same it applies to Aluminum bonding pads with gold wire! The following is an important note that applies to Surface Mount Multi Chip Modules. In the transition from SnPb solder to lead free and RoHS compliant packaging and assembly processes the reflow temperature has increased in some cases from 180°C to 220°C. This may cause an increase of the rate of formation of gold aluminum intermetallic compounds that are brittle and are conducive to increased contact resistance and or bond failure. This is one more reasons to avoid aluminum all together.
