IMS presenting at EDI Con Online 2022

Join IMS at EDI Con Online 2022! Wes Laquerre, Application Engineering Manager at International Manufacturing Services (IMS), will present the Signal Integrity/Power Integrity Workshop. Title: Assessment of Thick & Thin Film Passive Monolithic SMT Resistor Elements in Handling Low Duty Cycle (LDC) Signal Conditions Date: Wednesday, October 05, 2022 Time: 4:00 PM Eastern Daylight Time Duration: 30 minutes Register Today A study of risks and factors designers must consider when selecting a resistor component which will be exposed to low duty cycle pulse (LDC) power. Mechanisms and techniques to compare or predict durability of a given selection of thick and thin film components against a projected LDC form is also discussed. In the past 10 years, requests for passive resistor elements have revealed a growing trend in application specific signal requirements. These requirements include: moderate to high power, LDC pulses with fast rise/fall times, pulse widths under 1uS, low average power, and pulse repetition frequencies (PRF) ranging from 1 Khz to 40 Khz. Applications generally associated with these types of signals include Vertical Cavity Surface Emitting Laser (VCSEL) drivers used for 3D imaging and object recognition, Low Duty Cycle (LDC) algorithms used for [...]

Exploring Power Dissipation Thermal Ratings for Fixed Attenuators

IMS Presenting at EDI CON Online 2020! IMS is excited to join the global community of RF, microwave, EMC/EMI and high-speed digital design engineers at EDI CON Online 2020 for FREE, real-time networking, product demonstrations, training, and learning opportunities! Join IMS at EDI CON Online for a presentation on: Exploring Power Dissipation Thermal Ratings for Fixed Attenuators Presented by: Wes Laquerre, IMS Application Engineer Date: Tuesday, October 13, 2020 Time: 01:30 PM EST Duration: 30 minutes A number of thermal/power design challenges are found when PCB Designers evaluate the use of fixed attenuators. It is helpful to explore and understand relationships of applied power, dissipated power and the factors involved across multiple dB values of attenuators whether fixed in a component network or created using discrete individual resistors on a PCB. Understanding all factors involved with properly rating attenuators offers a useful insight into practical challenges. Further, understanding the best practices on how to self-evaluate applications and apply them to the components required to realize designs becomes even more beneficial to designers. Some factors explored here include termination style, pad and via sizing, operating temperature, component substrate, resistor size, trim style and tolerance as they relate to power/thermal performance.

New Models for Attenuators and Resistors Released by Modelithics

Modelithics® and International Manufacturing Services® (IMS) Release New Models for Attenuators and Resistors Tampa, Florida and Portsmouth, Rhode Island (January 31, 2019) – Modelithics and International Manufacturing Services (IMS) have completed the development of eight new broadband Microwave Global Models™ for IMS attenuator and resistor families. The models were developed through the Modelithics Vendor Partner (MVP) Program under a 6-year collaboration plan recently established between Modelithics and IMS. New models are now available for the following IMS components: RC3-0402PW, RC4-0302PW and NDX-1020EZW high frequency resistor families, A-0402WA-C/IMS2652 and A-0603-C/IMS2533 high frequency attenuator families, and the VDR-3725SG very high-power attenuator series. The VDR-3725 attenuator model is validated up to 2 GHz, while all other attenuator and resistor models are validated to 40 or 50 GHz. The new models are substrate scalable, pad scalable and part value scalable, with the exception of the 50-ohm single-value NDX-1020EZW resistor model.

Advantages of Partial Wrap Resistors

As sensitive inline RF performance influences new designs, designers are scrutinizing components quite differently. One popular technique being utilized by designers is “planarizing” the components so they align in the same plane as the transmission line in RF applications. Keeping the resistor and the transmission line in the same plane reduce losses and minimizes the effects of capacitance. At DC, the resistor is simply governed by ohms law. However in an RF environment, certain parasitic effects and contributions must be accounted for. The same resistor that performs termination functions adequately at DC or low frequencies can often exhibit different performance at higher frequencies due to unwanted capacitance and inductance present when utilizing various package designs. When using a wraparound, (WA) termination, the resistor forms a small series inductance and the chip terminals form a small shunt capacitance. As frequency increases the capacitance value eventually becomes dominant and must be managed. The partial wrap, PW resistors are designed to be mounted face down and therefore have better parasitic performance than the WA style under similar layout and operating conditions. The terminals are partially wrapped around the side of the chip so when they are mounted face down, the solder joint can [...]
