Hello There Charlie!
Sent the ol' dawg out again (woof, woof!) and he's been sniffin' for ya'
(gonna have ta get him some milkbones after today!..hehehe), he's found this:
Amitron, Incorporated
http://www.amitron.com
Telephone: (978) 686-1882
Fax: (978) 686-0622
Address: 85 Flagship Drive, North Andover, Massachusetts 01845
What is Amitron?
Amitron manufactures ceramic printed circuit boards and custom chip resistors
utilizing Thick Film Technology. Our manufacturing capability includes
multilayer circuitry, capacitor & resistor printing and fine line printing to
3 mils & etching to 1.5 mils line width and spacing. With our ceramic
machining capability, substrates can be configured to meet most geometrical
requirements
Our capability for custom resistors provides values from milliohms to gigohms
with sizes as small as .020" x .030". Chips can be provided with standard
solder over nickel plating or with palladium silver, platinum gold, gold or
silver terminations. Amitron chip attenuators have been tested and perform
well at frequencies as high as 18 GHz.
SUBSTRATES
Standard substrate materials include alumina (Al2O3) in sizes to 6x4 inches
and beryllia (BeO) in sizes to 3x3 inches.
Laser scribing .025" thick rectangular alumina provides the most effective
approach to meeting mechanical requirements. When necessary, substrates can
be machined or green punched to produce virtually any shape. Other available
substrate materials include quartz, sapphire, ferrite and kapton. See Also:
