Ironwood Electronics
Ironwood’s GHz BGA & QFN/MLF sockets are ideal for prototyping and testing almost any BGA or QFN device application. These ZIF sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss up to >40GHz and supports BGA or QFN/MLF pitches down to 0.3mm was utilized in these sockets. GHz BGA sockets are mechanically mounted over a target system’s BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry’s smallest footprint). They support IC devices with body sizes ranging from 55mm down to 1mm. Larger body sizes may require a backing plate. If the backside of the target PCB contains capacitors and resistors, a custom insulation plate with cavities cut for those components can be designed. This insulation plate sandwiches between the backing plate and target PCB.

On one hand, there are signal converters which transform an input frequency range into an analog signal. These signal converters are very easy to program and control. Other signal converters can transform analog input signals into analog normalized signals with galvanic insulation. Due to the fact that these signal converters can be freely graduated, they offer endless possibilities and 110 combinations can be selected by means of a DIP switch. Other kinds of signal converters can be connected to devices with RS-232, RS-485 or RS-422 protocols.

The Rotation Link SAS
Separates are typically rings and insulation material assembled on an axis along with separate contact brushes. They are usually designed with flying leads. Once integrated, they provide electrical contact between stationary and rotating parts of a slip ring assembly. They use bearings from the host system and provide a more compact and economical solution than self-contained Slip Rings. The coupling of these items requires technical skills from the OEM and is suitable for applications that have tight mechanical requirements.

Pickering Interfaces Ltd.
Suitable for use on the front of PXI modules this connector block provides a simple method of connecting to high density 200-Pin LFH connectors. The screw terminals use a rising cage screw clamp mechanism to minimize risk of copper strand breakage. PTFE cables are recommended for use with this connector block to maximize copper cross sectional area and insulation properties. Users should make their own cable strain relief arrangements and ensure that appropriate electrical safety precautions are observed.

Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.
