Keithley Hosts Capacitance-Voltage Testing Webinar

Keithley Instruments will host a 45min online seminar entitled 'Semiconductor Capacitance-Voltage (C-V) Testing Fundamentals'. The seminar will be broadcast on 29 October at 15:00 CET, to enable engineers based in Europe to participate in the live event. The webcast is free to attend, but registration is required.

The seminar will introduce the topic of C-V measurements as they relate to semiconductor device and materials characterisation. It is recommended for engineers who are new to semiconductor materials and device testing and those that want to refresh their knowledge of the subject.

SMT Connector Powers LEDs From Underside Of Board

Tyco has introduced the SMT thru-board connector, which supplies power from the underside of an FR4 or aluminium-clad PC board, eliminating issues of dressing wires on the top side of LED boards. The two-position through six-position connector surface mounts on top of the board, passing through the board to present an underside interface. The connector mates with standard Mini CT connectors. The inverted design allows simpler assembly and installation of solid-state LED lighting in architectural, residential and commercial applications. The Mini CT connector is rated for three amps per contact, on 24 AWG wire. A space-saving low-profile design and rounded corners minimise shadowing. The connector fits through a hole or notch in the board. High-temperature materials allow the connector to be reflow soldered, while a flat-top surface provides compatibility with vacuum pickup. The connector uses surface-mount hold-downs to provide stability during mating and unmating. With UL listing...

Electromechanical Relays (EMRs) vs. Solid State Relays Comparison (SSRs)

Image
Electromechanical Relays (EMR) Pros (Advantages) Lower initial cost compared to solid state relays. Provides complete electrical isolation. Tolerates high current & voltage transients. Insensitive to electromagnetic interference (EMI) / radio frequency interference (RFI). Higher open resistance (air gap). Lower closed resistance. Available with many poles/circuits (up to 8 or more). Many different circuit configurations available. Multiple packaging & feature options. Most typical failure mode is open. Electromechanical Relays (EMR) Cons (Disadvantages) Higher control (coil) power consumption. Contact arcing can cause pitting & eventual open/short failure. Contacts can be affected by corrosion, oxidation or contamination. Contact bounce possible due to shock & vibration. Generates electromagnetic interference (EMI) / radio frequency interference (RFI). Can be orientation sensitive. Can be affected by external magnetic fields. Subject to mechanic...
