Circuit Board Castellations Definition The industry generally accepts edge plating, or castellations, as copper plating that continues from the top and bottom surfaces and along one or more perimeter edges. Applications for PCB Castellation Edge plating and castellations are used in, but not limited to, edge soldering, edge connections, and current carrying capacity.

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

Definition Blind 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. Applications Blind and buried vias are real estate savers because features and lines can be designed above or below (without making a connection). Common Issues Laser drill, voids-desmear deash, hole preparation, copper plating. Click here to read more Cross Sections In-house lab features small hole accessory for microsectioning Cu-PTH vias.

PWB Sales History Three or more ounces of copper in the inner outer layers. Applications Copper thickness addresses the following: high power distribution boards heat dissipation planar transformers power converters Common Issues Delamination, inner layer alignment, etching and more.

Fine Line and Spacing PCB Design and Fabrication DEFINITION Circuit Board with 2-5 mil line spacing. APPLICATIONS Telecom Industrial Military Automotive COMMON ISSUES Tightening circuit designs for Miniaturization.

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