Definitionrf-impedanceControlled impedance maintains specified tolerance in the characteristic impedance of an interconnect (transmission) line used for connecting different devices on a circuit. ApplicationsPCB designers utilize controlled impedance for high-speed digital and high-frequency analog circuits. Our customers span these industries:MWRF, Telecom, DUT Chips Common IssuesSEC provides solutions for design and final product verification, puddling and more.

DefinitionDepth-controlled cutouts exposing inner layer(s) to air. Applications IndustriesCavities are required for antenna purposes as well component assembly in the following industries: Microwave, Telecommunications, and Automotive. SEC SolutionsRegistration, bleed out of bonding material into cavity, shallow cavity routing.

PWB Sales HistoryThree or more ounces of copper in the inner outer layers. ApplicationsCopper thickness addresses the following: high power distribution boardsheat dissipationplanar transformerspower convertersCommon IssuesDelamination, inner layer alignment, etching and more.

DefinitionBlind Vias start on an outer layer but terminate on an inner layer; Buried Vias exist only between inner layers and do not begin or terminate on an outer layer. ApplicationsBlind and buried vias are real estate savers because features and lines can be designed above or below (without making a connection). Common IssuesLaser drill, voids-desmear deash, hole preparation, copper plating.Click here to read more Cross SectionsIn-house lab features small hole accessory for microsectioning Cu-PTH vias.

Transmitting Heat to Less Critical Areas DefinitionThermal Management PCBs transmit heat away from critical components (or operating areas) to ancillary spaces using one or more of the following: metal heatsink , metallic cores (e.g, aluminum, Cu), and heavy copper plane layers. Applications IndustriesInitially prevalent in military applications, thermal management has extended to LEDs and Power applications. For more information, check out our LED PCB Resource Center.
