ROSS ENGINEERING CORPORATION
Extra high voltage, low corona, grounding relays of the air insulated type. Peak test ratings up to 300kV and 100 amps continuous. Units can be operated either by solenoid, motor, or air cylinder, with spring or gravity return. All models have spherical contacts. When voltage transient limiting is required, some models have an adjustable sphere gap. Also available are units with built-in high voltage discharge resistors with energy dissipation capabilities from 50 to 10,000 ohms. Some units can be reduced in height if full line to ground voltage is connected to the top high voltage contact only and the other high voltage terminal is operating at, or near, ground potential. Line to ground voltage can also be increased by adding insulation between lower high voltage contact and ground. Normally mounted base down. Base up mounting if specified.

63110A/ 63113A/63115A -
Chroma ATE Inc.
As shown on the V-I curve in figure 1, the LED has a forward voltage VF and a operating resistance (Rd). When using a resistor as loading, the V-I curve of the resistor is not able to simulate the V-I curve of the LED as shown in blue on figure 1. This may cause the LED driver to not start up due to the difference in V-I characteristic between the resistors and the LEDs. When using Electronic Loads, the CR and CV mode settings are set for when the LED is under stable operation and therefore, is unable to simulate turn on or PWM brightness control characteristics. This may cause the LED driver to function improperly or trigger it’s protection circuits. These testing requirements can be achieved when using a LEDs as a load; however, issues regarding the LED aging as well as different LED drivers may require different types of LEDs or a number of LEDs. This makes it inconvenient for mass production testing.

CB50 -
CAMI Research Inc. (CableEye®)
Populated with precision resistors, it allows users to determine empirically whether the tester requires calibration. The CB50 may be used on all CableEye models. The CB50 is intended for periodic verification of tester calibration. To ensure that resistance measurements remain accurate, CAMI recommends yearly calibration. However, depending on environmental conditions and usage, testers may need calibrating more or less frequently. Certain components within models M3U, M3UH, HVX, and HVX-21 (i.e. those capable of measuring resistance) are analog components whose characteristics change slightly over time. This aging is a natural phenomenon common to all electronic components and may cause resistance measurements or gradually deviate from normal. A tester that is out of calibration will give inaccurate results. Some (maybe all) resistance measurements will be incorrect. Consequently, it may Pass what should Fail and, conversely, Fail what should Pass. In other words product yield will be contaminated due to unreliable quality.

SEN-30004-K47 -
Playing With Fusion Inc
Four channel MAX31855 digital thermocouple Arduino Shield. Two versions of this shield are avaliable for each thermocouple type: either 'Ch 0-3' (CS pins use Uno/Mega IO pins 7-10) or 'Ch 4-7' (CS pins use Uno/Mega IO pins 3-6), with the only difference being which set of zero-ohm resistors are populated on the board. This allows use of other SPI devices that may be 'hard coded' to specific digital pins on the Arduino, or simply stacking one of each type together to get a total of eight thermocouple channels on one Arduino. The MAX31855K supports a measured temperature range of -270C-1372C with known thermal characteristics and output resolution of 0.25C. Included thermocouple connectors are type-specific to provide proper material continuity as close to the IC as possible. The SEN-30004 is interfaced via 3 or 4-wire SPI and a high-speed level shifter is included to allow the board to plug directly into an Arduino Uno or Mega

Autobuild™ Software -
CAMI Research Inc. (CableEye®)
Our optional, add-on AutoBuild™ software (Item 728) offers Guided Assembly for cables and wire harnesses. Use a supplied probe, or a finger with wrist strap, to touch an unterminated wire and the software shows (and says) exactly where the wire should be connected. As the operator attaches each new wire, AutoBuild checks the entire assembly and provides a clear checklist showing all completed good connections. When using our resistance-capable testers, you may connect diodes and resistors by name and value, check resistance values over the tester's specified range, and test conduction and isolation resistance against specified thresholds. Programmable tones accompany the graphic screen to give clear signals to the operator when good connections are completed or when incorrect connections, resistance violations, or diode insertions are detected. Combine with our Light Director™ option for light-guided assembly.

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.
