IMAPS PDC Webinar Series on
RF/Microwave Hybrids: Materials and Processing

This two-session on-line Professional Development Course (PDC) webinar was held:
Tuesdays, April 6 and 13, 2010

All webinars were held 12:00 noon - 1:00 pm EDT

IMAPS Members: $125 per webinar; 2-course series $200
Non-members: $200 per webinar; 2-course series $375 (includes one-year complimentary individual membership in IMAPS)

Registration Deadline: April 5, 2010

Key Words

RF/Microwave, hybrids, basics, substrates, deposition, photolithography, etching, transmission line components, wire/ribbon and via parasitics

Program Description

High frequency circuits are perhaps unique in that impedance matching between components is critical for proper performance. Transmission line effects, such as reflections must be controlled to prevent misinterpretation of data or other malfunctions. As a result the proper choice of material and/or fabrication process is vital to achieve efficient, viable circuits. Depending on the application, some combinations will be more appropriate than others. Each session is scheduled for 50 minutes of lecture followed by 10 minutes of Q&A.

Tuesday, April 6, 12:00-1:00 PM EDT

In Session 1 we focused on:  

  • Hybrids vs. MIMICs
  • High frequency basics
  • Planar wave guides
  • Current flow and loss considerations
  • Substrates
  • Thin film deposition

Tuesday, April 13, 12:00-1:00 PM EDT

In Session 2 we focused on:

  • Thick film deposition
  • Polymers
  • Process strategies
  • Photolithography
  • Etching
  • Transmission line components
  • Wire, ribbon and via parasitics
Richard Brown


Richard is President of Richard Brown Associates, a consulting firm specializing in hybrid manufacturing with emphasis on RF/microwave hybrid technology. Previously he worked at the Bell Telephone Laboratories, the RCA Solid State Center and RCA Sarnoff Laboratories in their Microwave Technology Center (MTC). At MTC he won 2 technical achievement awards. He has been awarded 9 US and 2 foreign patents, has more than 35 technical publications, including chapters in 2 handbooks and is the author of 2 texts. Major contributions include the introduction of innovative physical vapor deposition and electroplating technologies for the manufacture of high rel military hybrids, and the development of high performance, high frequency packages up to 18GHz.

In 1995 he won the John A. Wagnon Technical Achievement award from the International Society for Hybrid Microelectronics (ISHM, now IMAPS). At IMAPS he presents the popular PDC on RF/microwave hybrids. He is a Past President of the Garden State Chapter, and a senior member of IMAPS.

Dick is a graduate of Wagner College, Staten Island, NY, where he earned his BS in Chemistry and from Seton Hall University, South Orange, NJ, where he was awarded an MS, also in Chemistry.
