SEMICONWELL - SWKBME IS SAME AS PACKBME, PAC KBME, KEYBOARD/MOUSE PORT INTERFACE FILTER PROTECTION

SWKBME IS SAME AS PACKBME, PAC KBME, KEYBOARD/MOUSE PORT INTERFACE FILTER PROTECTION Stable resistor-capacitor network. Integrated solution. Saves board space and reduces assembly cost. ESD protection diodes. EMI/RFI filter. Pull-Up termination. ESD protection for keyboard/mouse port. The signals from the keyboard/mouse controller contain high frequency EMI signals that must be reduced before the connector. Likewise, that signals from the keyboard/mouse controller must be protected from any possible external charges such as static electricity. EMI/RFI filters are used to suppress noise at low high frequencies of the signals in the be-directional parallel communication between PC’s and peripherals. The RCD series solution improves performance and reduces assembly cost on passive components. These products are manufactured using advanced thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors, gold interconnect metalization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. In die form, these products are ideal for hybrid and multichip module applications. In package form, these products are the best solution where space and weight are a concern..Semiconwell manufactures passive network components, integrated active and passive devices, resistor networks, capacitor networks, schottky and zener diode networks, and npn, pnp transistors arrays that perform the following functions: series and parallel linear and nonlinear GTL, AC, Diode, Thevenin termination networks, precision thin film resistor capacitor networks (RC networks), isolated, bussed resistor networks including zero ohms jumper arrays, voltage divider networks, resistor networks for audio applications, EMI, RFI and ESD zener clamped diodes and transient voltage suppressors networks, EMI/RFI filter networks and clock terminations. Semiconwell's proprietary semiconductor technology, advanced thin films processes, in house assembly and packaging technologies allow manufacturing of flip chip CSP chip scale and MLF molded lead frame surface mount integrated passive networks that include unprecedented large capacitors >1microfarad (1µF) and giga ohms resistors (GW).

SHORT PRODUCT APPLICATION NOTE

TheSWKBME is a single-channel keyboard or mouse port termination device. The SWKBME integrates EMI/RFI filter components R1 and C1, and also incorporates two pull-up resistors R2. In addition, it provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The I/O pins and the V DD pin are designed and characterized to safely dissipate ESD strikes of 30kV, well beyond the maximum requirements set in the IEC 61000-4-2 international standard. Using the MIL-STD-883D (Method 3015) specification for Human Body Model (HBM) ESD, the I/O pins and the V DD pin are also protected for contact discharges of 30kV.

SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION

Integrated passive networks are manufactured using advanced 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 resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
